Protecting my bottom against the insertion of foreign objects is a major security goal of mine.

"This is the lockpicking lawyer and what I have for you today is a safe I stumbled across from the local bank"

These handles were on the residence rooms in my dorm, back in the day. Students figured out they could use coat hangers to open the doors. "Hardening" ended up just being us students who were concerned taking our door handles off, rotating them so they were vertical with the handle hanging downwards in the neutral position, and it left little for the attacker to get hold of with a wire like this.

As a locksmith I went to a class on high security access control locks the instructor had not seen the tool before and I showed him how it worked and he was amazed . I thought it was hilarious 😅

The easiest way to defeat this is to place a cat on the other side of the door.

I tried this for myself, the door didn't open but the toilet flushed.

Round doorknobs would be quite effective countermeasure for this kind of device. Upd: thanks to everyone for response guys, i learned a few new things from you. Building regulations are not that strong in my country, so round doorknobs are still very common.

Instead of "breaking and entering", your crime will be just "entering".

When LPL himself says "Okay, that opened WAY to fast" you've got yourself a great little gizmo

I’ve watched this several times and Noticed he gets smacked in the head every time, so eventually after a 100 or so times you will forget this technique.

As we say in the door hardware industry, locks only keep honest people out! Thanks guys.

Hard barrier sweeps or caps at the bottom won't help against this tool if there's carpet (like in most hotels) - you can still easily press the tool under the door. Source: I was a hotel manager on the night shift for 10 years and unlocked 5 to 10 doors a week, every week, for guests who had someone passed out inside the room with the deadbolt latched (usually drunk). For those that might wonder how pulling the handle releases the deadbolt, in hotels (at least the ones I worked with) the deadbolt is linked to the handle being opened. It's a safety thing, so that if there's a fire or some emergency and the guest needs to evacuate the room quickly, they only have to turn the handle - no fumbling with a lock that they are unfamiliar with.

If all else fails .. notice the hinges are on the outside of the door.

I was wondering why Deviant was staring so intently at me in utter silence at the start of the video. But it was just because my speakers were turned off.

I made a makeshift version of this tool, and was able to get into my room without paying a lockout fee - dorm in college. It worked great. Thanks for the amazing video!

When I was at the University of Waterloo in the late 1970s, we called these devices "Bishop's Hooks", and we used them to get into the underground tunnels. The administration responded by welding cans around the door handles so we couldn't reach them.

"OK, just hold it behind your back and look natural." 0:00 "Like this?" "Perfect"

"Who are you and how did you get in here?" "I'm a locksmith and... I'm a locksmith".

Yeah. When I was in college I made a similar device out of coat hangar wire and string. I used it when I accidentally would lock myself out of my dorm. I got good enough to work around hanging towels. It was a nifty, yet crude tool. But it got the job done.

LOL! Love how he tried to downplay smashing his head. It didn't go unnoticed.

*hiding behind security door* "I think we're safe in here, the door is locked. They can't get to us in here." muffled voice: "This is the lockpicking lawyer, and today we are going to be using a classic under-the-door-style tool."

"Bosnian Bill", "deviant Ollam"... Seriously, your friends sound like the characters of a Tarantino movie 🧐

His Defcon talk on elevators still hands down my favourite Defcon talk. Fascinating stuff

In Sweden we have threshold under almost each door, even interior doors.

I really like deviants material. Watched most of his talks. Smart guy.

when that door opened i was amazed how quick that was

I missread the thumbnail as "most effective, most destructive entry tool". I was expecting a wildly different video.

"covert entry methods and defenses against them" sounds like a wizarding class :))

1:02 When the door opened and Ollam stand up and hit his head against the door handle it made me laugh.

I made lot of these in the army for when people locked themselves out of they're rooms. A lot easier then going to CQ

Im a house burgalry and you have No idea how much help ive got from your videos i thank you and so does my customers. Um err i mean those i break into to help save them from their goods and objects. Best of wishes a Swedish House burgalry living in Texas ☺️

I use a tool just like this at work (with a ragged ol piece of 550 cord attached) to open dozens of offices each month. We call it the fishing pole. Our locksmith calls it a K22 tool. It really does work as easily as shown here for the vast amount of lever office doors in the 200+ buildings in which I service. Great vid!

I love when people have "high security locks" and they get locked out so I just pop open a ceiling tile and open the door from above! their reaction is priceless, they spent thousands of dollars on their door locks and I can open them with a broom from above the ceiling. also beside the door is typically drywall which is not very strong either

Seems like a door knob instead of a latch would easily defeat these threats.

Yet another reason to hate handles that still turn when the door is locked.

Figured this out with a coat hanger in 2002 when my dad locked the computer room. Those sounds of it riding the inside of the door before getting the handle brings back memories.

and the real answer is in his back: a doorknob instead of a handle.

Every horror movie: You are now locked and chained 10 levels deep and have to kill each other to get out. LPL: ... *tires screeching away* The End.

Best crossover, Love both of your channels.

Props for the LockPickingLawyer for not cracking up when the other guy hit his head with the handle.

As my father once told me, "locks only keep out the honest thieves".

Me sleeping at night thinking that i'm Safe *Some one at door* *this is the lockpicking lawer and what I have for you today is *

Used to be a locksmith and I love this tool!!!

People, are watching and using your technics im sure. Thanks for all you do.

My favorite part is at 1:02 when he opens the door so quickly, the door knob bonks him square on his head.🤕 The reverse shot at 1:16 is a whole other take. 👍

Good ol' Deviant Olaf.

Eyyyy! Ollam this man has eaten so many hours of my day just rewatch ING his conference talks and stuff on key alikes

I never thought I’d ever see someone get through a lock faster than you. :)

Back when I was a locksmith, this was one of my favorite tools. We always called it “Big Al”. I don’t really know why it earned that name, though. It was always funny to see people’s faces when we’d get called out to open someone’s inside office when they’d locked their keys inside. I’d open the door in about 10 seconds, just like the video, and their jaw would hit the floor. 🤪

Is no one going to talk about how he hit himself in the head with the door after it opens?😂😂

Smooth operator! Thanks for sharing 👍

Jeezus this makes it look easy!! I'm thinking out of sight, out of mind is still the best way to go

My wife was visiting the US from England recently, and about 2am she heard a noise outside her hotel room. She got up and walked to the door to see this tool being used to try and open the door. Thankfully she had the chain lock across the door, but she made a noise and the guy ran off. She called security and they didn't believe her. She called me (early in our morning) in a state of shock. Once I got her calmed down, and spoke to security, they reviewed the CCTV tapes and saw the guy. He had tailgated someone into the hotel, and reception were too busy on Facebook or something, so he slipped right past. He picked a random door and tried to get in. In the UK at least, almost every hotel needs a key card to be able to use the elevator, and so access to corridors is quite hard if you aren't a resident. They called the Police but there was nothing they could do. Needless to say she is now pretty scared every time she stays in a hotel by herself. Just thought I'd share that with you. Keep up the good work LPL.

Love the collaboration with Deviant. Keep it coming. I wanna see more.

I'm a patient at a psych ward and my visitor once a month let me watch this vid on their phone. Thanks!!

I use ceiling wire when we are locked out of offices in buildings, even though we had clearly asked for access in order to work there.

I was drinking coffee when he hit his head. Now I'm wearing coffee.

For the “dub, use a round doorknob” crowd, realize a lot of building codes and ADA require lever style handles.

I've had to use this method to defeat a bio-metric scanner on a server room door. Another thing people forget is going up and over by moving the ceiling tiles if they didn't design the room well.

For a round knob, you tie strings to each end of a belt, use the coat hanger thingy to loop the string over the knob, pull until the belt is over the knob, increase pressure on both strings to get the belt to grip the knob, then use the belt to turn the knob. Not as fast, and a bit trickier, but it can work if you have a big enough gap at the bottom of the door. Or use the “key to the city” from the SWAT movie.

Cold climate makes these types of attack (both top and bottom) totally impossible. The doors have to have proper heat isolation and now I know that there is an added bonus.

"That was way to fast!" -LPL. Yet when he picks master locks, I'm saying the same thing! "That was way to fast!" 😂 In fact, come to think of it, that is the same thing my ex-wife used to say to me!

There were too many double entendres in this video for people to resist capitalizing on. I don't blame any of them cuz they're funny!

I like how he mentioned all these crazy ideas to solve the problem when a simple deadbolt would suffice

"Deviant Olaf?!" Sounds like some weird Disney spinoff!!!

1:18 - simply remove the "hook" end at the end of the door handle, and shorten the door handle to just long enough to fit your hand. A loop over it will slip right off.

Two of my favorite KZfaqrs in one place.

A simple magnetic piano hinge that flips up with door closed as door closed it has multiple fingers along it that bite in to the doors bottom we have been able not even get a wire under it.

congratulations on 1 million subs!! well deserved!

In environments where sound proofing is desired, a drop down seal from the door can be triggered as the door closes. If there is a floor plate with even the smallest lip that works in conjunction with this, you can negate this kind of attack.

Those locks are usually available in a knob or a lever on the inside but some building codes may require the handle type.

To the left of Deviant Ollam (to his right) there is a door handle invulnerable to such attack

oh damn I've seen this guy's Defcon talks. Tons of interesting stuff

This guy looks like those raptors in Jurassic Park movie. Hero: "Are you sure the raptors are secured" Heroine: "Yes, unless they figure out how to open doors"

Very neat the control string actually bends it in a perpendicular plane to the door !

Would simply changing the interior lever to a knob defeat this? I realize that the lock would then probably no longer be ADA compliant.

We call this an "airman's key". Everyone in the dorms who locks themselves out uses this

This is the same concept as what we called “cat’s eye” unlocking where you poke a tool thru the peephole. That’s why our locks can’t be open with just a handle pull but a button must be pressed as well to unlock

I lived in a student corridor once. It was not uncommon people looked themselves out of their room. The easy solution that everyone knew was to of course just remove the hinges, as they were on the outside.

LPL: check out this new tool! Me: ladies and gentlemen, the door knob!

"This is the Lockpicking Lawyer and today I'm going to show you how to get in when the neighbour locks you out of his house."

I’ve been waiting for this all night

Also swapping for a knob type style handle would mitigate this as well.

Abloy/Finland, has a 2 stage method, where you need to turn a knob even on the inside to turn the handle

"anything that can prevent the insertion of foreign objects will help you out" #GeneralLifeTips

After reading some of the comments on this video, and the top door video, I wonder if it would be useful to have a short explanation of how the Americans with Disabilities Act (ADA) and certain fire codes influence door design. It seems quite a few people don't understand why door knobs aren't a thing anymore outside of housing, why you can't just "lock the door from both sides," and why having doors that move freely and loosely are prevalent.

I have a buddy who lives in a different town. His door lock had a flaw where if you slammed your hand down and twisted just right you could open it. I'd visit with his door still locked and be in the dark on his recliner waiting for him to get home. Good times. He started circling the block after getting home to look for my car.

At least in British Columbia you can’t install door KNOBS has to be levers like these, because people with hand issue struggle with knobs. Well LPL just added to the discussion.

Sometimes the door gap does need to be that big. It’s actually often specified when building to allow return air flow to the air handling system.

I just enjoy how this nice guy is part of the video, he is so into it :)

Always love your videos

you should have added a picture of that albino alligator at the end of the video.

Another with the fan favourite Deviant "I'm not supposed to be here" Ollam.

I love the fact that 200 years ago people put proper heat insulation on their doors and it protects against most attacks other than attacking the actual lock. There's something beautiful there.

I admire LPL's work, since a very very long time, especially the passion and time that he has for it. But you have to admit that this whole channel is the representation of one of USA's biggest issue. There are so many countries where we don't even lock our car knowing that nobody would ever try to open it. Here we learn about how to secure our doors and guns against the weirdest attempts to bypass the securities.

This is how we'd get back into our barracks rooms on Fort Bliss when our key cards would quit working.

Just install the lock upside down, very effective to stop cats from escaping

I cannot believe that’s a real tool - GENIUS

I used to do maintenance at a hotel, yes that is the go-to method, those key locks have batteries that need replacement now and then.

Oh man, gotta love when two favourites work together.
