In 5 years you’ll end up finding a underground nuke proof bunker

So I looked up the number 863 and it's an area code in Florida. This got me thinking, a lot of those numbers (the ones I can see anyways) are three digits which means they could all be area codes. So I wonder what would happen if someone took all of the codes and plotted them on a map. It reminds me of once when I was doing an escape room where we put pins on a map and in the end, it spelled a word. So maybe if we did that for all the numbers and their area codes, it would tell us something? Matthias, can you take a picture with all the numbers visible and put it on Instagram or something so we can all over-analyze this? Please like so he can see, thx. (Thank you all for your sweet comments! It makes my day.)

Imagine the former tenants watching this video saying "Oh thats where our lost keys went"

Yo it’s so weird rewatching this and seeing people in a store without a mask. Man the world has changed so much in a matter of 8 months

Matt: Talking about his migraine. Luna: Running around in circles.

Key Theory: Get a thermal gun and check the wall in all the bases.

It's strange seeing them walking over those wooden stairs and having no idea what's beneath them.

Woods and Matt are like Peter Parker and iron man

imagine this all leads to a box with a piece of paper inside saying "goteeem"

Get a thermal gun... you can scan the walls... the hollow areas are the more colder areas and the non hollow areas have insulation making it hotter... a thermal gun could work just use it around the base and try to see if you find anything... also the safe was made from metal so if the metal is conducting the cold air, it will also be picked up by a thermal gun 🤨🧐😉😉 Also if there is a key... there will be a lock

Y’all I can’t. Knowing that there’s a room under those stairs and then them sounding hollow when Matt stepped on them TRIPPED ME OUT

Who is here when the safe has been open with that weird guy who broke in

Theory: have Conner run into every wall until you find another safe

Key Theory: Hoooold up here so mini-rant. The original key was found in blue then you guys found the file cabinet in orange( i now know it was originally in blue...but still) and now there is stuff in red... I think there is stuff in every part of the building they're at. Like it was all one big place at one point and they hid stuff in different sections then spilt it up and sold it. Matt, I sincerely tell you to get the original, as far back as you can, floor plans for the complex your at. Also, the ghost stuff doesn't help it. ( If you can make sure Matt sees this that would be great comment section.)Update: Tanner just thought the same thing I did... What?

It’s so weird rewatching this from the beginning after everything that’s happened, i will forever be a fan of you

Am i the only one who cant belive that this was like just a couple months ago? just me?

Who else remembers when this all was going on like 2 years ago Now it’s 3 years haha Coming up on 4

New Series Idea: each episode is trying to figure out where each key leads

I like how you own a company but you couldn’t figure out that it’s binary code

Is it just me or does Kevin start acting really suspicious when he’s asked about the keys? Like, out of all of them he’s the most sober about it. And he’s been there through all of it. AND Kevin didn’t really want them to break walls.

My suggestion about the keys. Because they are all custom keys as in, they have designs like star wars, California state flag ect. I would assume that each key is to a specific persons safe. And since you said that the people who owned the building before you had labs, maybe each key goes to a specific persons safe where they kept record of their research and experiments. Something interesting about those key tags that you may not have known is that people have been known to take that center paper piece out and split it in half then hide something inbetween the two halfs. My suggestion is to go through each key one by one and see if any are hiding QR codes or coordinates to anything.

There has been scavenger hunts like this that lead people to treasure or it can lead you to something that someone is really trying to hide from the world. You guys should totally try getting a scanner to scan the walls and floors and see what you could find and look for the original blueprints of the location and try to find out the past of that location like what kind of business use to own the place and when it was built and look for all the previous owners and the history of the location

When Matthias has the humidifier on his nose he looks like a villager from Minecraft.

The way Matt switches to clips of him talking reminds me of the office 🤣🤣

use a metal dedecter to find more safes in the walls

when I saw those keys they reminded me of the keys that would be used to unlock and lock the lab desk cabinets and lockers at my college, the formatting of the tags is the same system of organization. Usually chemicals and lab equipment is kept in the desks which need to be kept safe and locked up after use. Those could all just be back up keys to those desks, or there was something in some of those desks that someone didn’t want people to know about and hid the keys in the wall, but why wouldn’t the company take those with them, and why do some have prints? My other thought is, that system that we use is the same organization system that some banks use for organizing safety deposit boxes. If someone went to such lengths to hid those keys they must go to something valuable or something someone wants to hide, what better place then a secure and safe bank.

Am I like the only one who heard ones and zeroes and instantly thought Binary? Edit: Guess Mat and Sam are the only ones who didnt

Matt asking Woods "do you want to be a part of it?" Maybe he should have said no.....

Matt literally has a different personality in every channel he’s in

Here is my key theory: You said that this used to be a lab, correct? With the key kit, they made personal keys for the employees to use for their research notes in locked areas. The numbers on the keys would be the codes for the locks. Those keys you found are the back-up keys encase something happens to the employees or they need to access it. My guess for the key hunt in the first video would be where they kept the back-up encase something happen to the owner and left it hidden.

Now rewatching the series I wonder if all of these keys are meant for all of the different timelines.

omg it was PEAK comedy when connor made the cereal fell, that was literally SO FUNNY

I mean this might be weird what if they go to storage units

I CAN’T A year later and the mystery key returns WITH HIS FAMILY

Now that I see the stairs, I can't forget the things that I now know about them...

The real question is how the heck does the stalker get a safe in the wall and then cover it up like nothing happened?!

Well they solved that mystery, on to the next. Lesson of the story: Matt, keep buying more units in the area.

I feel like one day we're gonna find out this was all just Woods screwing with them.

Little did they know...... It escalates. Fast.

you are literally the luckiest person in the world to not be allergic to dust

Key Theory: Metal detect the walls for more lock boxes/safes...

The person probably wanted to keep it secure from anyone that why there is so many keys because they wouldn't have so many keys to hide something. Also there was a mini safe with a key that said TS5 which is a desk key. LIKE FOR THEM TO SEE THIS IDEA

Matt- “I’ve seen the back side of a lot of things but not locks” Woods- *trying his hardest to keep in laughter*

I still love this episode so stinking much. there is something about the beauty of these discoveries that are so innocent. It still makes me so happy to watch these old season 0 episodes.

I say, take the drawers of the desk off (where the kit was found), check for things written on every surface no of the entire desk, and check for false bottoms in drawers. Also, try to see if anything on the desk can be removed, such as the top, a side, or part of the bottom. Not only the desk can be used though, so every wall that wasn't changed, try going and using a stud finder on every wall (yes, EVERY SINGLE WALL) and seeing if something unusual comes up. And regarding the keys, try taking them and comparing them to keys that you have that go to office doors and stuff, then those keys can be eliminated as useful. Any that don't match up to any office keys, set aside and keep track of them. They are likely to be useful. My uncle used to find and collect evidence in crime scenes, and when they have no leads or ideas, they try doing these things. An alternative way to all these things, just see if you can get an expert on it. Or a whole crew that specializes in stuff regarding this whole matter. Also, don't let the situation sit and slowly disappear, please. (Added note: like this so it can be seen!)

I’m pretty sure that Hi5 Studios is just built on the site of a haunted escape room.

I bet you have all saw those stairs thinking “omg those stairs have an Apple 2 under it” at least that’s me

I come back here sometimes to remember where it all started. A puny key in the ceiling.

Dude my curiosity bone is tickled because of this Office style vlog

So remember what you guys found a year ago... *Here we go again*

After 3 years watching this back brought memories back and noticing that there’s some way to translate those number from the QR code

Im rewatching the whole key thing right now and I literally remember all of the videos coming out on this channel. I can't believe its been going on for years

I can't tell if this is real or not. Hi5 is haunted I swear. 😂

“Wild goose chase simulator: Keys Edition.” Coming soon.

Who else is looking back on this and knows what some of the keys go to?

Tanner: “I can’t believe 863 had resolution.” Me: “Less like a resolution and more like an inciting incident.”

Fake Wall:”Nobody will Know What’s Behind Me” Connor: I’ma End This Whole Man’s Career Like this if you want them to make this in like a series

When matt has no clue what binary code is.

Remember when gunner said that it could be a safe and he is right

this is where it all began. Its amazing where it went. A fantastic series!

Matt acting like he doesn’t know what binary code is is hilarious 😂

What if the numbers on the keys lead to different building addresses that they owned or built

at 25:12 under mat there is the biggest plot twist ever

When you watch this to help with the safe and you realize you remember when it was posted

Theory: the previous tenants saw your key video and just decided to make a bunch of fake keys.

I would laugh if all the keys lead to nothing but a empty safe with $1 and a note saying “Use it wisely”

Here from John Doe video 1/15/21 , 843 actually shows up under 615 at 31:55

I love how the desck was right in front of the secrat starcase room

My theory: They may lead to a buch of safes, OR they used to be keys belonging to previous workers rooms or something until they quit or got fired, and finally what if in one area or multiple areas,they have a wall of lockers with secrets or belongings of past employees, and when the company disbanded they put them there, leaving behind anything in those safes? O_O ok now i want to make a story about this, like an actual book, if i do just know this video caused it :D Edit: Thanks for the likes 😅☺️

It’s like that episode of the office where Jim created a random scavenger hunt for Dwight as a joke, forgot about, and then when it came up he couldn’t remember if he actually hid anything or not, but it just turns out that one of the warehouse workers had already found it and had been using it.... maybe someone already found the thing you think your on the verge of finding... 😂

*faint in the distance* this is a story all about how my life and I got turned upside down-

I get migraines all the time when I get severe anxiety. Mostly from school, and I end up vomiting 5-10 times and it can last up to two days

Ideas that can probably help: 1) Ask Izzy/Israel 2) Use a metal detector at the walls 3) try these keys on the hi5 bases doors and see if they work on a specific door and then maybe search that room Edit(s): 4) Get a locksmith that can probably help y'all out Reply with more ideas that I can edit in this comment so Matt can see!

Key theory: There’s another safe some where maybe even with more keys. In the keys you found only one of those go to the safe and all the others are just to confuse you. My suggestion get a thermal gun and search the walls for more safes

Remeber when this was the end of the key saga

Honestly when the safe opened, it reminded me of those old fashioned hotel key racks. Like at wall behind the front desk when you first walk into the main lobby. Maybe they go to rooms of an abandoned hotel or something wild...

The line "Daddys trying to vlog" is a perfect example of this generation

Matt: We found a safe in the wall Me: NOT ANOTHER SAFE (still watches)

24:56 he didn't even know he was so close to the rabbit hole

HE IS CALLING A BINARY CODE!!!!!? DIDNT EXPECT THIS FROM YOU MAT!

And here we go, back down the rabbit hole of curiosity.

This was likely the resident locksmith leaving himself or a future locksmith a note. The numbers on the locks might not correspond to anything the previous tenant was aware of. You may find a 3 digit number stamped on the faces of locks throughout the building. Potentially ones you already have keys to.

8:18 is where it all began. our beloved gangs first mystery which would lead to many fallen tears and questions what are yet to be answered. remember to breathe :)

3:16 “Some tenants left over some stuff that they thought we’d appreciate” I don’t think they’re appreciating it...

“Who has that much keys”Said all of them Me “they own an escape room”

THE RETURN OF THE FILE CABINET IN THE CEILING

When the crew walk around with their phone, they are like playing games such as Pokemon Go.

2:02 did anyone else see the glitch?

Ask Kevin if he still is able to contact the old residents but don’t tell him why then ask them about it

Matt: talking about really serious allergy stuff Luna: * runs circles around him*

Man. After some of the latest videos having to do with the mountaineer, and syntech. Its crazy go see how its transitioned out of that vlog style and more into a "help us solve the mess that is our lives"

I love how this gives me the office vibes with the little “interviews” Matt did

My thought: the keys are to lockers/mailboxes. That’s why each one has a different number on it, it’s the locker number.

Omigosh. Now there needs to be a group of people with metal detectors that scan the walls. That's literally their job.

It's crazy to see the team coming together

Over a year later, I would have NEVER guessed that these mystery vids would end up being THE channel. Crazy

This gave me major “The Office” vibes, Matt being Michael Scott, Sam is Pam, Connor is Dwight, Tanner is Jim, Hannah is Erin, Woods is Andy, Amanda is Jan

Key mystery ideas: When looking at a multi part puzzle, look at the similarities and the differences of the objects (keys in this case) and see if anything forms a pattern. Numbers on the tags, color of tags, colors of the keys, special keys (like the star wars one) Sort them and order them in the different ways that makes sense and see if anything else makes sense after that. Does the design on the keys form anything if you take the first letter (S for star wars, C for California) and sort them by color/number/etc? Compare the bitting on the keys to see if there are duplicates, or if they are part of a system set. Look at hidden places, like behind the paper and on the back side of the paper on the tags. Does the amount of keys correspond to the number of hangers in the key box? Use it as a template by hanging the keys in the different orders mentioned above, and see if anything new appears. And the most obvious, try them in all the locks in the building ;-) Time for a little Easter egg hunt ;-) Good luck and stay safe.

Once he's done with Battle Universe he should make a new universe where these keys are a whole thing.

34:35 the only thing that scares me is how many times has Matthias done this??!?!?!?!?
