Imagine sitting in a theater and the guy infront of you is just sitting there with a keychain full of locks, slowly picking them

“Honey is everything okay? You haven’t picked a lock for hours”

At the movie theater: "sir, do you want some popcorn?" "No, do you have some LOTO padlocks?"

I've worked in the industrial field for 15 years and I think I know the answer to your paradox with the loto locks. A given employer may have thousands of these locks on their site at a given time (sometimes 10+ per employee), and possibly use millions of locks over the course of their business lifetime. You absolutely cannot have a key that matches a lock anywhere else than that one lock it is tied to, that is a big insurance and safety problem. So the more pins allows for more key variations. Also, people are constantly sticking their keys into the wrong locks accidentally, and so the higher quality core allows for less chance that they will force the lock open before they realize it is the wrong lock. I do this multiple times a shift, because I have several locks issued to me with many similar keys and I typically just go through them until I find the one that opens (I know I should label them). The more pins means there is more variety for the keys and less chance of a duplicate on site. The higher quality core, which is in all likelihood regulated by law, means less chance of someone forcing a very old lock open. The reason the quality of the housing is so poor is intentional. You want to be able to cut or even smash the lock off in a hurry if you have to. Maybe there is an emergency and you think of a way to operate the machine in order to try to save someone who is injured. Also, more benignly, people leave for home with their locks on machines all the time on accident handing off to other shifts. So you don't want some sort of monster lock on there that you can't get off without the key. The cheap build makes buying them much more affordable for employers, when they buy thousands of these at a time. They are not security locks, they are safety locks. High volume that must meet stringent safety standards (6 pins) for various reasons, but are not meant to be undefeatable in all circumstances.

Could you imagine sitting down with your husband to watch a romantic movie and you hear “2 clicks from 3, 4 is binding” very quietly

The LPL Paradox: he's Master Lock's biggest customer as well as their biggest enemy.

The lockout lock has probably saved lots of lives. Many years ago I was developing electronic sign control software with a fellow named Jimmy. When the electricians were working on the sign (3 phase, 400 Amp service), they would put a lock on the breaker box and put the key in their pocket. Jimmy would invariably want to test something and would run over to the breaker and try to turn on the power while the electricians were up a ladder and inside the sign.

I'm a chemical operator and I do lotos essentially daily. We have all 3 locks in this video mentioned. The plastic body is by far my favorite for its light weight (we often have to carry 30-50 at a time) and it's ability to endure weather and corrosion. We work with HCL, sulfuric acid, h2s, chlorine etc and the other locks in the video pretty much always get siezed closed in our harsh environment. The plastic ones can remain in a lockout for months and will unlock months later without issue whereas the metal ones often have to get cut off due to corrosion.

Don’t mind me while I pick these locks during the film.

when youre construction worker in a dangerous place with a switch that could kill you and you hear "number 4 is binding, got a little click of him"

As a safety professional I can explain the paradox. This is the best LOTO lock because the likelihood of mistakenly taken a lock off with a similar key is very low and uet it is very easy to remove by force when an employee goes home and locks out critical machinery. There are procedures in place to cut a lock and Noone not even management can unlock the lock without destroying it. These are Industry standard and in my carreer I have never seen the other locks he has shown. This lock is ideal to its purpose.

As an industrial electrician, I've seen a good amount of contractors leave site permanently without taking off their LOTO locks. Therefore their locks needed to be cut off. Assuming this is the reasoning for the low security exterior.

These locks are hard to pick. So hard in fact, I pick a whole ring of them while I pay attention to other things.

This video is hilarious for several reasons: 1. The fact that he has a keychain full of locks instead of keys 2. The fact that he picks those locks just for fun while watching movies 3. The fact that he said "I know a lot of you are probably thinking..." followed by some random lock picking jargon.

Masterlock: A maker of fine practice locks for lock picking hobbyists.

I can just imagine lpl watching the notebook with mrs. Lpl and while she’s bawling her eyes out he’s just quietly saying to himself “click out of 3, ooh 4 is binding” 💀💀

Imagine robbing his house and seeing a safe with 20 locks on it. You spend a full day getting in and your realize he just has locks that protect his locks..

Imagine him sleepwalking and picking all locks in the neighbourhood

the additional pin(s) are not for more security, it's to reduce the odds that someone will accidentally have a duplicate lock in a multiple person lockout situation. complex operations can have a dozen or more LOTO locks on one piece of equipment.

I use those plastic LOTO locks at my job everyday, and the reason why we use them is because they can be broken open pretty easily if someone forgets to take them off and leaves with the key. Not sure if that's why they're designed that way, but at work they're pretty much just to remind someone that an area or piece of equipment is locked out.

Netflix and Pick? Goes to the dates house - “You got any good locks I could take a look at?”

Coming from someone who has over a decade in the oilfield industry, my guess behind the plastic body would be for economic purposes. These are used as safety tools to keep someone from starting up a unit, rather than keeping someone out of your belongings. Considering companies purchase these sometimes in hundreds or even thousands at a time, the plastic must save some money. Not to mention how often they get lost or stolen by employees.

If there was an incident at a LOTO job site and tampering was suspected, a broken or cut lock is far more obvious than one that had been picked. When my sig is on a LOTO, the last thing I want is someone to easily pick the lock, cycle the power, pop the lock back on and exit the area. That could make an investigation very difficult.

LPL doesn’t have a set of house keys. I imagine he just brings his picks everywhere and hotwires his car every morning

Master Lock is just trying to balance their locks. If a lock had maxed out stats, that would be overpowered. Therefore they balance their locks with strength and weaknesses to promote variety in the lock meta.

Reason: it's a breakaway lock. It is made to be snapped off with a simple tool, like a pair of pliers, in a hurry. The sophisticated core is a deterrent. It's there to ensure the lock wasn't removed in a malicious way. If you don't have they key, but someone is getting cooked alive because a valve didn't hold or a line blew, you need to secure a line NOW. No time to find the guy with the key; you can bypass it in a hurry. If it was a simple lock, it could be picked easily and quickly by someone with malicious intent. So the core is there to help raise the question: "Why was the LOTO removed?", if it was removed improperly.

As somebody in the construction industry the best reason I can give is if something happens to that worker who has the key and the key is lost, a set of bolt cutters can get everything up and running again with minimal effort. Most of the time these locks are nearby sensitive switches and equipment and you don't need to be struggling to get them off.

Sees video name: masterlock Sees length: 7 minutes Nonono, this can't be right.

A lot of people here seem to be missing his point quite dramatically. He's not saying it's inherently stupid that these LOTO locks have really good cores and terrible bodies, he's saying that it's crazy that all the other locks Master Lock make for actual security purposes have terrible cores when this clearly shows that they have the technology and knowledge to produce some really good ones. He's saying that it's weird to waste these really good cores on locks where it doesn't matter as much at the expense of their security cores

Lockout tag out is practiced mostly by electricians for "locking out" electrical circuits aka turning them off and then tagging it with name and phone number. If this circuit was somehow to get turned on while getting worked on someone could die. Not designed for anti theft. Power tools are every where. I could cut the shackle off with my linemens aka side cutters. Other companies make lockout tag out locks with a picture of the person attached on shackle with "Do not turn on, my family depends on me" written on lock body.

As otherwise mentioned, we use these for safety in the oilfield for, "Lock out, tag out" of valves and pumps when equipment is shut in or being serviced. Where these are used can often be bypassed with a wrench or screwdriver to disassemble the handle or leaver leaving the lock intact. What I leaned from this vid is that they have great cores that will help prevent accidents and serve their purpose perfectly. Well done LPL, always interesting and informative.

He doesn't like movies that don't have a lot of tension.

'I can't believe he didn't cry at titanic' LPL: 'Okay, nice click on 3'

The most secure part of these locks, honestly, is the LOTO policy that goes with it. When trying to remove an LOTO lock without a key is a fireable offence without several pages of paperwork, it doesn't need to be pick/break proof. We had a bit of a problem with people confusing which lock was theirs since sometimes machines can have upwards of six locks on them. I bought a sheet of stickers from the dollar store and it looks odd, but it works.

This was probably done to provide as many possible key variations to prevent multiple people from having the same key, since it’s a lockout lock and they are generally key different. It provides an extra level of safety to ensure a lock isn’t accidentally removed and equipment re-energized.

Him picking locks while watching movies as practice totally explains why he can pick a lock in 30 seconds and say, "that's a good security lock"

I've worked with LOTO locks for years, and can comment on why the design is great for me and my coworkers. The shackle is un-hardened so an authorized Safety team member can use standard bolt cutters to chop it if someone's lost their key. Additionally, we use these so often that we wear them on our belt, so the lightweight plastic-exterior design really helps to not tear up your pants or bounce around too much. Finally, we use these locks several times per day for years, so perhaps the extra pinning helps the keys stay firmly in place when we're walking around with the key in, or continue to safely function. Or perhaps there was some court case where someone picked a lock and someone got hurt. I'm not totally sure, but that's the information I have!

We use this exact lock at my workplace working on trains. We often have to carry around 3+ of these when going out to jobs. It is very light so convenient to carry. If we had to carry those solidbody locks around it would get really difficult so I can understand why the design is so lightweight. They are very reliable I've been using the same ones for 10+ years.

Glad that I saw this video. My grandaughter-in-law needed to chain and padlock the driveway gate while my grandson was working a shutdown and this was the type of lock that she found in their tool shed. I was skeptical cuz it looked so plastic and flimsy. Glad to know that it isn't flimsy.

As a former LOTO supervisor, I can chime in on this one. The 6 pins core allows for a larger number of pin combinations which means that my 375 locks all had a different key. Although my department had the lion’s share of these locksets, my company had other departments & sections that each had their own LOTO locksets, each with their own keys. That way, unless you had the key, you couldn’t open the lock. These locks are only there as a reminder that the device is not to be operated. As such, there is no need for the locksets to have hardened shanks or body. The problem is that keys get misplaced, lost, or even broken. After a thorough investigation, the only resort may be to cut the lock The LPL didn’t work for us and a locksmith would cost more than buying a new lock. It’s all about economic options.

When you're watching a movie with the boys and one of em just starts picking locks

Master Lock: This is our highest security core. Customer: Oh, then this goes into water treatment facility locks? Master Lock: No, those get weaker cores, as they already have a strong body. Customer: Uhm, okay... So what is this used for then? Master Lock: Our LOTO Padlock. Customer: What would that be? Master Lock: It's a fancy Post-it, basically.

This particular video still resonates with me when looking for a lock. This video is the single reason I have watched so many LPL and BB videos. This single core has shown me how a lock intended for a $150 bicycle can be made secure enough to protect several thousands. I use this knowledge to smith my own locks, as well as play with home made picks. I even have a set of my own home made pins. About 40 total between key/driver pins and bags of almost every manufactured pin size. I'm every bit of a low level hobbyist, and I can make better locks from my scrap bin than what master sells.

the body of a peasant but the heart of a knight, this little lock would be a nice movie protagonist

I want to see the LPL review movies based on how many locks he was able to pick during the running time. A better movie will be more distracting meaning less locks picked. I think it would be a really good scale.

We use these at my work alot, the only reason I can think would be a good reason it has strong core. The reason would be that you don't want someone discreetly opening the lock, if someone snaps or breaks the lock it's totally disabled and clearly something is wrong, while if they pick it then flip the switch then re-lock it , then it could be perceived as still working properly but it's actually an unsafe scenario

LPL is the type of person to open their house locks with a lock pick instead of the keys

Fun fact: The way Master Lock makes their locks is very similar to the way the Empire makes their death stars.

The strong core is so the wrong key does not accidentally open the wrong lock by the ignorant new guy on the crew . The weak housing is so the lock can be busted open in an emergency. I worked in the engine room of a commercial tugboat, we had these all over the place.

From the viewpoint of someone who’s a novice with locks but experienced with industrial equipment, here’s my take: 1. 6 pin core to increase the total number of key combinations. Repeating key combinations within a plant or even a company is usually a no-go. 2. High security pins because industrial equipment can vibrate A LOT. I have first hand seen a lock open on its own due to nothing more than vibration. 3. Plastic body because it is non-conductive (some other lockouts have rubberized coatings).

As a complete noob starting picking today, I used one of these as my first lock, as well as a random Brinks lock I found. I would just like to mention for the Master Model 410 LOTO lock, once picked, do NOT over rotate the core past 90 degrees, for if you do you will drop all of the key pins into the lock body. Spoken from experience, that satisfying clunk of a lock picked followed by the jingle of all 6 key pins falling out filled me with a lot of emotions. Lesson learned. Thankful this video was here for reference. As for the core, can confirm, 5 spools and 1 double serrated on 5. Also, picking using LPL Genesis Set.

This one jumped out at me because I'm manage safety in a semiconductor lab. I think we have a "little column A, little column B" thing. 1. Weight. This is a factor, not because of carrying them, but because you might need to attach it to something small. For example a household style circuit breaker, a heavy lock could damage the breaker or the devices used to attach to the breaker. I have seen cases where the LOTO loop on a valve was broken through over time by the lock hanging on it. There are also cases where multiple locks are attached to the same point and you don't want 10 pounds hanging from even a robust point. 2. Cost, these locks go missing, get cut, get damaged, as someone who has to maintain a budget I can't spent $10000/year on locks. These buggers are expensive anyway, so if Master saves me $5/lock I'm grateful. 3. "Strength" defeating a LOTO usually results in termination, so they don't have to be strong. Seeing a red lock generally implies "mess with me and get fired", that's where its true strength is. 4. Secure core. I think the high end core is for good reasons, as I mentioned a decent sized site could go though a lot of these, I keep 25 new ones in my desk at all times, the EH&S manager probably has 100. So a decent core means more randomized keying. You don't want the wrong key to work, not when the result could be death (or many many deaths if it involves toxic gas release ). You also don't want the core to wear and allow the wrong key to work. Finally, despite the threat of termination, you don't want it defeated too easily, key bumping etc. 5. Authorized defeating. People lose keys, we have had people leave town on vacation and forget to switch locks, sometimes a LOTO can be in place for years. So the lock should be easy to cut when appropriate. It's also possible the lock is in a position so that you can't access the hasp so being able to cut the body easily helps in these cases. Anyway, that's just my 2 cents from 35 years in industry.....

**LPL at the movie theater concessions** “Hi what can I get for you?” “I’ll take a large carabiner of locks please” “..........”

The plastic is both non-conductive and non sparking. Both are really important in an industrial environment. The six pins probably have to do with the number of key combinations possible. I use them a lot at work.

The community in these creators comments is one of my favorites on KZfaq. Like the "tuxedo tshirts" of commenters. Lol 😊😅 what I mean is, everyone is here just to have a good time.... but there are hardly any trolls and *for the most part* people don't act or speak disrespectfully. Wholesome jokes and lighthearted fun. Formal, but here to party too.

"Do not remove" People trying to break in: *darn*

I think master lock exists just to troll this man.

Your videos are quite fascinating. The answers to your questions are simple. Master sells these things by the hundreds of thousands, and the sets of 6 locks for each worker is supposed to be unique so that no other worker on the site can open the lock. The fragile construction is so that if the worker has flown home and cannot return to remove the lock he forgot to remove at the end of shift, then a supervisor can use a bolt cutter to remove the lock. There are usually disciplinary action taken against a worker that had his lock forcefully removed by management. This is the case in Australia where people are quite anal about safety precautions.

Omg!!! I have been trying to pick my loto lock for years. Just on my breaks and such. Today I finally did it after watching how you did yours. Thank you. It’s so exciting to watch it finally turn. Lol.

You have officially scared me with that caribiner full of locks that you use to practice picking while watching a movie.

Panic mode; Wiring up a 3 phase relay when you hear this from the breaker box, “Number 2 feels good, 3 is binding”

I doubt you’ll see this but, I work in an industrial setting and my guess would be that like you said they wanted a core with plenty of options, maybe a factory with thousands of employees and each employee expected to carry multiple locks, but being a LOTO lock you don’t need security you just need a glorified sign saying somebody is inside this machine. You do however need to be able to remove the lock easily if the owner loses a key, breaks the key or say they go home and forget to remove the lock. I know the keys aren’t exactly delicate but if you lock and unlock a locks dozen times a day every day for years on end the keys eventually get worn pretty heavily. I’ve had multiple locks cut off machines for all these reasons.

These looks are placed on lockout switches that are generally power switches made of plastic and I think it's more to do with electric insulation and anti tamper than security as the switches can be removed very simply with a screwdriver

in Australia these loto locks are the standard because technicians lives are at stake. industry standards require a lock that is difficult to tamper with but possible to remove. the theory is that it is too difficult for someone to pick open and remove then have someone switch on or turn the valve and later claim the lock wasn't on then replace the lock back to the switch. but is easily cut off if the lockout lock is left behind. so it's made to easily detect brute force attacks but remain strong against non damaging attacks or tampering.

Hey you down in front - "STOP MAKING SO MUCH NOISE WITH THAT DAMN PILE OF LOCKS!!"

Friendly reminder if you see one of these out in the wild: Do Not Touch! My dad's an electrician and was working in a factory being gutted and renovated, and of course had turned off power and locked out the breaker panel using a similar lock. Turns out that the offices attached to the factory weren't wired correctly when it was built, and one guy lost power to a single outlet in his office. He decided that was Unacceptable and so walked into the construction site, snagged some bolt cutters from somewhere, and Cut The Lock Off The Breaker!! My dad was, at the time, on the top of an 8foot ladder cutting through a 6inch conduit with a reciprocating saw. In short order he found himself flat on his back 3 feet from his ladder holding a now very dead saw, complete with smoldering saw blade. He needed stitches in the back of his head, and thank gods that's all he needed. If the power had been turned on ever 30 seconds earlier his hand would have still been directly on the bare conduit! He would not have survived that. Those locks are so absolutely important and should NEVER BE TOUCHED if in use.

That's amazing how a similar lock that's used in my work industry has a plastic body, when you can go grab several types of tools or battery powered devices and just cut the body away! I like knowing I'm protected fully when I'm the one inside doing work and relying on these type of locks!

Imagine how many locks he goes through during a single movie...

My heart dropped to see the thumbnail with your name on it, showing the lock i trust my life and limbs to everyday. After watching I left more than content. Thanks from one on the line LPL.

The reason it has a seemingly secure pin setup is so that there can be MANY different keyed locks on a GIANT job site, so there are less chances of keyed alike locks, because if someone unlocked the wrong padlock, someone could die. If someone does lose their key, the bolt is easy enough to cut if everyone onsite agrees the lock should be cut. I believe, that the design and choice of features are specifically designed to suit the needs of certain buyers. I’ve seen all of them at different job sites, there is no security threat inside the job site, which is why a plastic body is ok. Great video!

As a former crew chief at a factory, our dept. had like 150ish of these. every once in a while you would have someone drop a key down a flume, or grate etc. and need to get one of these off of something. (After filling out a bunch of paperwork and whatnot, to get the OK to do so) we found out really quick the best way to get these open was a big old set of channel locks, and squeeze the shit out of them from both sides, along the seam. they fly apart and it takes literally about 1 second.

Something tells me he has another whole ring of locks in his bathroom for when he’s sitting on the toilet

2:28 This part always sounds like a really bad day at the dentist.

I would say that they design most locks now for saw, angle grinder, pry attacks which Master has been pretty decent with. They just don't see the picking as a main attack possibly. At least they don't seem to be focused on that side of it. But it is a little concerning when they have these nice 6 pin cores available cheaply and they chose to put a 4-5 pin basic core in all the top "Magnum" series.

I worked at several power plants as an operating technician and one of our duties was to secure equipment that needed maintenance, that could involve chaining and locking valves, removing fuses and open breakers etc and they all needed to be locked down and a sign with the correct work order number. The locks was all the same and all of the us technicians had the same key, so when the job was done anyone of the technicians could remove the locks when the job was done. The jobs could take hours, days or weeks so it would probably someone else then then one that had secured the equipment earlier that would be on duty. For all sake I could had found, say a faulty pump, switched over to a spare and then written a rapport on it and then secured it for the maintenance crew that would take care of it at day time. No one removed the locks without an ok from the maintenance crew as it could spell disaster and even life threatening danger.

Feels like it's almost a tamper-proof seal in a lot of ways, it's easy to bust open in an emergency if needed, but not easy to open without any trace ie picking

Netflix and chill means a whole different thing for the LockPickingLawyer

I use these locks daily for my equipment. These locks have plastic bodies so they can be more easily destroyed. LOTO procedure prevents anyone, besides the person who applied the lock, from using it. If a person of missing and the lock needs to be removed there is a lot of paperwork and a lot of attempts to get ahold of the employee in question (so that we’re sure that they aren’t locked inside the equipment.) afterwards a pair of box end wrenches can be used to blow out the non hardened shackle. Or alternatively, bolt cutters are used as well. But the main reason is to make sure that the lock is difficult to pick, but easy to destroy.

I love that you will keep your hands busy during a movie with your hobby/craft. I do the same!

Nobody: LPL: Here is my keychain of the 7000 master locks I pick on the daily

I picked up one of these when I first started. because it was plastic I thought it would be a easy open. boy was I wrong.

As a Pipe welder/Millwright, I’ve cut several of these LOTO’s off over the years using my “master key” (metabo) lol. Love the videos!

HEY WHAT DID YOU DO TODAY. Oh nothing just watched a movie and picked 10 or 15 locks eating popcorn with Ms LPL lmfao. LPL YOUR FREAKING INCREDIBLE it's amazing to watch you pick these locks with so much Finesse I have not yet seen a video where a lock gave you a hard time would like to see it lol👍😎🇨🇦👍😎🇨🇦👍😎🇨🇦

LPL: "...or in some sort of zone of danger." Sterling Archer: *inhales*

Masterlock R&D: “We just designed the most secure lock EVER!” The Board: “So it’s flawless?” Masterlock R&D: “YES!” The Board: “Garbage, throw it out.”

To this day this is my favorite LPL video. Its an oldie but I still use these locks daily.

I always love watching his videos, it's my asmr when I want to relax

The reason for the core is because you can potentially have 20+ people locked out at one time; we did it at one of my old jobs. With the generic 4-pin Master cores, you could definitely have some overlap where someone's key accidentally works on the wrong lock and they unlock the wrong lock...which could be deadly if you have multiple control panels. This is just their way of making sure keys and locks don't get mixed up.

"Hey, take a break from the locks for a minute and come watch a movie with me" "Sounds good, I'll meet you there!" *takes a chain of ten locks to the couch*

I love picking while watching a movie too. Best moment to use time more wisely

1:36 Perfectly shows the difference between LPL and a normal pro locksmith. Professionals learn lockpicking for work, and usually only what they need to know for most jobs. People like LPL (experts and enthusiasts) do this for fun, at literally any time or place, and they end up with way more practice and odd knowledge as a result. Similar logic also applies to most industries.

In e movie theater: People kissing each other for the first time LPL: Click out of two 😂😂

I've smashed a ton of these locks as a PLC programmer. Millwrights or electricians do some work, forget the lock and then go home leaving a machine in a locked state for the next shift. We call the name on the back, get verbal confirmation the machine is safe to run and smash it off with a hammer. Saves lots of time removing locks but I suppose everyone involved needs to respect the kind of honor system there.

I use these, and there is a good reason. The locks are tricky to pick for most people so removal is always destructive if the key isn't available. This is a safety feature. It's about the LO/TO policy of the company using the lock. The plastic lock combines a cheap to buy and replace (when it's inevitably cut) lock with maximum key combinations to minimize the chance of a duplicate in an organization.

I have been waiting a few weeks now for my Covert Companion to arrive (I live is Australia so everything takes time from the US), finally it arrives and I’m straight into putting it together (thanks for the video on that LPL!) and then madly looking for locks to pick open - the only two I could find around home are a tiny Lockwood travel luggage lock, picked on my second try, and my Masterlock isolation lock the same as this video. I was getting frustrated and disheartened that I can’t even open this little plastic lock - feel better now lol, maybe off to the shops to buy some other practice locks somewhere in the mid range 😂😂

Lockpickinglawyer at cinema popcorn stand: Hello could i get a padlock to pick during the movie?

It is a desirable feature for these locks to be relatively easy to break. Many times locks needed to be broken when an employee left the facility without removing their lock. A supervisor was allowed to break the lock after locating the employee and verifying that they were no longer at the site. Usually these locks were used with hasps that were even easier to break than the locks. As far as I know, these locks are not useful beyond compliance with OSHA regs.

Normal people: Concentrate on the movie or sitting on their phone. LPL: Opens Master Locks for practice

Im an electrician and we use the plastic loto’s alot. Its good to know they’re difficult to pick. Usually the device it’s attached to is all plastic (breaker lockout) and can be broken off easily. What keeps most trades from screwing with them is you can get some hefty jail time for tampering with one.
