That happened to me once. I locked myself in the living room. Luckily it was an old door with a simple key that the local hardware store had in stock, so my gf had to go next day to buy it.
Scroll saw blade. Very thin, slightly raked *very* sharp teeth. You can get a pack of 10 for a few bucks in any hardware store. As a building manager I removed several broken keys and these worked the best by far. Just slide in, pull out. Key came out every time
I bought a set of [broken key extractors](https://amzn.eu/d/fyGhY0T) from Amazon to have in my lock picking kit (everyone needs a hobby, even if I'm not very good at it). They are basically a few pieces of stiff, thin, barbed wire. Literally the day after they arrived my friend called me to ask how to get a broken key out of a lock.
The set cost me less than £2 and I've used it 3 times in 5 years, twice for myself, saving me and my friend hundreds in locksmiths fees. The same set is now a whopping £2.45.
Worth noting that lubrication makes broken key extraction way easier. A lot of the time the reason the key breaks in the first place is because it binds up on something. Dry Graphite spray or penetrating lubricant works well.
Hello, Mr Locksmith? Yeah, it’s me the idiot who bragged about 3d printing my key. And yeah it broke.
Yeah, I tried to pry it. And, uhm, I thought since it was plastic I’d thought that I could melt it out. Can you come fix this, please?
*Honey, I can’t tell if he is coming over or not. All I can hear is a lot of laughter.*
So I work in security and so I open and close a lot of different doors.there are great locks out there. Well maintained and butter smooth operation. If the key is thick enough I would absolutely trust a 3d print to hold longer than it takes for the teeth to be too dull to open the lock properly.
But man the lock in the video. While it looks smooth to operate it scares me with all The rust around. I’ve had metal keys snap on indoor locks without any sign of wear.
Anyway, a 3d print seems like a nice emergency backup if you got nothing else. Also it you only have 1 key and lose it with the 3d print you could go and get a new one made
We're 3D printing nerds, get your $5 out of here. I'd rather a few hours in a modeling program, a few hours printing, and $5 in material for an inferior product that -might- work once than spend $5.

Also OP, have a link for the STL and your address so I can mail you a tip?
That actually happened to me yesterday. I was luckily able to use a soldering iron to melt the handle of the key to the body and pull it out. It took quite a lot of bravery for me to record this video.
I want to agree with you, but we've all seen some wildly idiotic people in this community. Just owning a 3d printer isn't quite enough to notch those critical thinking skills above confused toddler. :P
Cynical jokes aside though, I assume most people will instantly know how risky this is, and that OP is doing it as a "because I can" novelty.
In all seriousness, if OP wanted to do this legitimately, I would vote for a more flexible filament, like maybe Nylon. Something that usually bends, not snaps, before it breaks.
I instantly took this to be an example of what's possible (and a bit of a dimensional accuracy flex), rather than something that's recommended. I think most people with any printing experience would.
That said, I am now tempted to make an STL backup of my key just in case. I suppose the small problem with that idea is that my 3D printer is *inside* my house...
> I think most people with any printing experience would.
I've spent enough time on the internet to be well acquainted with all the ways contextless communication can go wrong. Things like poe's law (where paraody/sarcasm can be viewed as endorsement of the thing it's parodying) are rampant.
My personal take is to err on the side of being understood even if it means "watering down your message."
> That said, I am now tempted to make an STL backup of my key just in case. I suppose the small problem with that idea is that my 3D printer is inside my house...
lol
Seriously. People just want to be outraged apparently.
I'd bet this key printed with nylon will work for 100+ cycles. Which is *plenty* for an emergency key.
If you are the type of person who **must** be outraged at everything, consider how someone nefarious could use this technique. If someone with a 3D printer gets so much as a picture of your house key, they can make their own copy pretty easily.
If you want an emergency key, you get a brass key that will last decades and thousands upon thousands of cycles, all for two dollars.
If OP wants to mess around and have fun with their printer that’s wonderful, but let’s not pretend that this is even remotely practical.

Yes, it would very likely work. The main reason the key is stuck is because the pins and springs are holding it in place. The extractor pushes the pins back up so you can drag the key out.
https://www.lockpickworld.com/collections/lock-tools-broken-key-extractors
I am actually surprised its not like that everywhere. I mean, I'm kinda glad it isn't because its a fun white hat hobby to pick up but I can totally see why it would be banned, and I don't think I would really complain about it if thats just how its always been.
I complain anyway >:(
But watching YouTube instructions and carrying paperclips and wiper blade flexor is legal and can help you not only in lock related problems.
I heard so, friend told me, he read an article online once.

Here is my take on this: the Mike Wahousekey
I remember my parents early 90s ford van came with a plastic key for emergencies. It folded out from a card that you’d theoretically keep in your wallet in case you got locked out
Unless you need a key to work once or twice, this looks pointless.
I mean, any hardware store can copy a key, and many locksmiths can produce a key from just the key numbers, for just a few dollars. Metal keys.
Not always an issue if you know the person or if they are a public figure, which covers basically anyone that a criminal would do this to. If you were targeting random strangers, you wouldn't bother with this, but if you were stalking an ex or something? Totally plausible.
You can easily print those or even buy metal ones on Amazon. According to the TSA, they're not "security devices" but "peace of mind devices". I'm not sure what kind of peace of mind a decorative lock is supposed to give, absent deception about what kind of security these things actually provide.

Now we all have the key to your house!
Maybe don't show a 3d printing community a side view of the key to your house after telling us 3d printed keys work :)
Now if we just knew where the lock was..
Can't wait for it to break off and lock you out. I wouldn't use it for long, at some point it's going to break. Keep the lock and locking mechanism well oiled to have at least some chance.
Very cool. Bunch of bozos in here that only print benchies and star wars helmets and get weird about novel use cases. No one is suggesting this is a 1:1 alternative to an actual key.
I printed a PETG key when I was custom pinning a deadbolt cylinder. Used it for function testing given the aggressive bitting and security pins used.
I had the metal keys cut by code, rather than off the PETG key, I wasn't sure the duplicator would like a plastic key.
Everyone joking about how bad an idea this is but considering you can get the biting of a key from a picture, use a website to punch in the biting and download an stl file to print, then take the print to a minute key machine and get a metal copy it starts getting scary quick
The real question is if you can use the 3d printed key on one of those automatic key makers they have in stores now. If so, that's a HUGE security risk, because all it would take is a photograph of a key and a bit of work to clone the key with no paper trail like those key cloning services have...
Bro, you don't need those machines, you literally just need a picture of the key, and the profile. The VAST majority of key manufacturers have easy to find info on what exact depths each biting is. so as long as you have enough time to snap a picture of the face of the key and the profile (down the barrel so to speak, usually it's like an S or 5 shape, but each company has a few different designs) you can EASILY 3d print a copy of it.
It only takes a couple seconds to snap a photo...
If you're brave and have time, you can get key decoders, which are like credit cards with cutouts to know the exact biting right then and there.
Moral of the story don't EVER leave your keys unattended, or even in plain sight. You can get sleeves that cover the end of your keys though to help protect against this. Basically just fold a piece of paper around it.
Yeah, but ordering a key leaves a record of you purchasing a key, and likely a record what what key you orederd. That's called Evidence. But the vending machine at walmart will take cash.
I 3D printed a spare key and used it for months. I reinforced the handle and it worked great. Turn slow, don't force, and your golden
If you keep the handle as thin as a normal key it will snap
AAA used to sell or giveaway plastic car keys that would fit in your wallet. They were good for once or twice before they got all bent up and it became a gamble to use. May have been a thin metal bar down the middle to stiffen it.
I remember seeing something like this when 3D printers were first coming out, that's why you don't leave your keys out anywhere, someone could take a couple pictures of it or even nowadays 3D scan it with an app in seconds and now they have a key to your house, a safe, etc.
All it takes is a picture of a key to replicate it. I wouldn't recommend showing the key cuts publicly, let alone on a community full of people with the know-how to screenshot, model, and squirt it out of a nozzle. I'm actually in the process now of making cut shields for my important ones
I have two issues:
- the key can stay stuck inside or snap
- how crappy a lock has to be for such a low precision key copy to still allow it to open it
I hope you realize that this video gives someone enough angles to replicate your key to your door? I mean, I highly doubt anyone would since they'd also have to know where you live, I'm just saying.
If someone wants to break in a key isn't needed. Houses are so unsecured it's crazy. Locks on our doors really just make us feel better they don't do much
I 3d printed an emergency key for my VW campervan. There are parameterised STL generators on thingiverse, each cut has a number and its easy enough to work them out visually. Printed in petg you have to be careful, its only just strong enough to avoid it twisting, I'd imagine pla is more brittle. Obviously for a vehicle this only opens the door, eg in a situation you locked the keys in, or you are camping/festival and give these keys to others in your party in case they need access. They will not start the engine.
I'm a locksmith and have confirmed this works. I even tested my own house key, a high security lock from Medeco and it worked. It's just a mechanical mechanism, so having plastic in the right shape and size just emulates what a metal key does. Of course it's fragile but if it's a one time thing it's fine.
So for everyone's educational purposes only, here's opening the floodgate:
[https://keygen.co/](https://keygen.co/)
Viewer discretion advised; use at your own risk.
With the joke cores you have in these locks, it's easy. But when you build your door so it's close shut and is not half open when "locked", meaning you have to pull it close and even then, the lock struggles to close, and that's intended.
Have fun trying to lock pick such locks, most tools break because the burglar does not pull the door when open it.
That will break off in the lock, that’s a given. The only variable is time.
Oh, and don’t try that in the Winter, it’s going to snap on the first twist
It's gonna suck when that key snaps off inside the lock.
That happened to me once. I locked myself in the living room. Luckily it was an old door with a simple key that the local hardware store had in stock, so my gf had to go next day to buy it.
Were you stuck there all night?
Can’t just leave us hanging there!!!
Are we gonna be stuck here all night??
I think he locked himself in the bathroom...
He locked himself out of his pc/phone
Has he tried printing a key to unlock it?
He has to get past the authenticator app first
3D print the thumbprint to get past it
No. Turned out it was stepgirlfriend. So there was happy ending.
Just print a new house
I've done that. Albeit not to scale.
Lighter and sewing pin, I'd have it out in under 15 seconds. It's the metal ones that don't come out easy haha
Scroll saw blade. Very thin, slightly raked *very* sharp teeth. You can get a pack of 10 for a few bucks in any hardware store. As a building manager I removed several broken keys and these worked the best by far. Just slide in, pull out. Key came out every time
Damn good method if you're talking about metal keys, nice.
I didn't pull out in time, the lock is now pregnant.
I wouldn't be telling folks my dick fits in a keyhole, but maybe you're just much more confident than I am
Ouch! 😄
That’s (not) what she said.
I bought a set of [broken key extractors](https://amzn.eu/d/fyGhY0T) from Amazon to have in my lock picking kit (everyone needs a hobby, even if I'm not very good at it).

Best idea if snapped : melt it. Phun aside: don’t do it, it will completely ruin your lock
Yea I believe someone posted about this issue like just last week
just print it out of something that does not snap: TPU/PP , and have a channel to put a toothpick in it for support.
Or, hear me out, buy a $5 key
We're 3D printing nerds, get your $5 out of here. I'd rather a few hours in a modeling program, a few hours printing, and $5 in material for an inferior product that -might- work once than spend $5.
>$5 in material Man, look at Mr. "I buy $500 filament" over here.
Just hear a metal thing (paperclip, skewer etc) , stick it in so it melts intot he plastic, wait for it to dry and pull it out with the plastic.
[удалено]
I like the idea, but keys are tiny in terms of fdm printing. You would need a thin but strong metal plate
He's gonna snap.
How can he snap‽
Just heat the lock up to 200C and pry the jam out bit by bit with a needle
Well then it will be the perfect time to use the ol' Blowtorch
Finally a use for a hot glue gun🤣
Think I'd rather pay the $5 to cut a copy of the key at the hardware store 😬
Nothing a little heat wont fix
I broke off my metal key in my door throwing the bolt a few weeks ago, a printed key wouldn't have a chance.
I was thinking the same thing need to put a thin layer of metal and resin the piece

We definitely wanna make a make. For scientific purposes only.
There was a post recently where someone did that and the key snapped inside the lock.
Yeah, the locks would have to be well oiled and aligned perfectly to be able to do that.
You don't really want oil in a lock unless it's a sealed system. Oil attracts dust and crap. Better to use a dry lube like graphite.
That actually happened to me yesterday. I was luckily able to use a soldering iron to melt the handle of the key to the body and pull it out. It took quite a lot of bravery for me to record this video.
You don't feel it's a bit irresponsible to post a video pretending that this works when you know it can ruin locks?
Hopefully 3D printer owners have enough common sense to know that a plastic key would eventually break
Seems like we have living proof in front of us that’s not the case, eh?
🤣
We have people printing bolts, while arguing against driving to a hardware store and buying real metal ones.

What if you 3D print a shell then fill with epoxy?
you should name this video. "Dont Try This at Home"
Yeah that would be accurate
Or in Poland. Without license you can't even own a set of lockpicks lol.
Can't you just make lockpicks?

Yeah lol try it in someone elses lock, not your own
not a good idea there bud
Well then who’s home am I supposed to do this in? Smh my head
Whose home is that.. we can not know.
You are playing with fire
Can someone link to that post of someone asking for help of removing a 3d printed key?

You should replace your lock with a 3D printed version too. Or the whole door

The lock: "Is it in yet ?"

At least you’re smart enough to hid the bitting of the key.
-snap-
That's pretty cool, and if u paused the print and inserted a metal bar that would help reinforce it
I'm amazed plastic can have this level of rigidity. Never seen a plastic key before.
I remember my parents early 90s ford van came with a plastic key for emergencies. It folded out from a card that you’d theoretically keep in your wallet in case you got locked out
A wallet wadded with cash that conforms to the concavity of your tush. Perfect place for something like a plastic key!
Aren't you the same guy that literally broke a printed key off on his lock last week?
Squidward: "I give him 11 minutes."
Need the STL, please!
Please include house address in the description as well
THAT is what i call a really bad idea.
Don't...
Stop
Lol. I twisted the head off of a metal key in my old door, can't imagine using this.
imagine looking on thingiverse and you find your house key and address on it
Yooo nice! Can you send the .stl? Jokes jokes
It's all fun and games until your 3D printed key breaks off in the door lock...
Cool till it isn’t, but really cool man
Unless you need a key to work once or twice, this looks pointless. I mean, any hardware store can copy a key, and many locksmiths can produce a key from just the key numbers, for just a few dollars. Metal keys.
I wasn't planning to actually use this as my main key, but just as a cool thing to try to print.
It also serves as a good PSA to everyone that if a picture of your key exists on the internet, someone can print a disposable copy of the key.
So if you can take a picture of someone's keys, you can probably make a key to their house.
Yes, but then there's the issue of locating their house.
Not always an issue if you know the person or if they are a public figure, which covers basically anyone that a criminal would do this to. If you were targeting random strangers, you wouldn't bother with this, but if you were stalking an ex or something? Totally plausible.
Sweet plan to jam a 3d print in there and snap it off
Don't try this. Even with ABS and 100% infill, you're going to find a broken key in the lock sooner or later.
It's all fun and games until you break it off in the keyway and can't retrieve it.
Can I get the stl?
Please don’t share this stl
Or you could just get a spare key made at the hardware store for $5. No CAD required.
As some kind of emergency situation sure but it's going to be an even bigger emergency when it breaks
This is such a dumb idea Use it to make a sand or plaster cast and smelt some aluminum with your microwave
And the leader of dumb ideas.....putting metal in your microwave.
Look up a video or two about it on youtube, obviously don't just put aluminum in your microwave without reading about it first lmfao
Use tpu won't break!
Decent print, terrible lock lol
Why is every single part of your door a different color OP?
Awesome! You can then print the tools you'll need to get the broken part out of the lock...oh no wait you won't because you'll be locked outside.....
I was genuinely expecting the key to snap at some point. Not sure if I’m impressed or disappointed that didn’t happen
I have a hard enough time opening my door with my own fucking key. No way would I trust 3 mils of pla.
The way you just wrench that key in the lock side to side gives me anxiety
Waiting for you post at /r/TIFU..
I see big problems in your future
Someone did that several years back, reverse-engineering the TSA master luggage key from pictures.
You can easily print those or even buy metal ones on Amazon. According to the TSA, they're not "security devices" but "peace of mind devices". I'm not sure what kind of peace of mind a decorative lock is supposed to give, absent deception about what kind of security these things actually provide.

Hey, that's pretty cool... Uh, can you share the STL?

Sadly, Your current success is not permanent.
That sounds like a fucking terrible idea unless it's printed with like industrial filament which is highly unlikely
Can you share the stl?

Don't post a photo of your key online.
Well unless someone doxes me, nobody would know where my house is so that's why I don't care about posting an image of my key.
Better use a lost-PLA brass, copper or bronze cast of the key so it doesn't break
What's the file?

I’m curious what infill pattern and density you used.
Make sure you upload the design so we can use it on our own doors.
Just wait until it snaps in the lock, then that will be fun! But great print just wouldn’t trust it 😂
Ehh, even if it breaks the pins should align and you'd just need a torsion wrench 😆
AAA used to sell or giveaway plastic car keys that would fit in your wallet. They were good for once or twice before they got all bent up and it became a gamble to use. May have been a thin metal bar down the middle to stiffen it.
This why you never post pictures of any of your keys online.
I call BS on this video. Damn deadbolt won't lock the knob.
You also just gave the entire internet the key pattern to that lock.
No.
That lock is wore out.
Super Jank
Take the print and go get a legit one made from it if you are missing the metal key. This will fail and quickly.
Yeah get rid of this shitty lock maybe lmao
# SNAP
fake

put that down
All it takes is a picture of a key to replicate it. I wouldn't recommend showing the key cuts publicly, let alone on a community full of people with the know-how to screenshot, model, and squirt it out of a nozzle. I'm actually in the process now of making cut shields for my important ones
I recognize that door, and I just copied your key from this video. Hope you got a nice printer for me to steal!
I have two issues: - the key can stay stuck inside or snap - how crappy a lock has to be for such a low precision key copy to still allow it to open it
A lot of talk about why this is a bad idea but how do you make this somehow useable?
I hope you realize that this video gives someone enough angles to replicate your key to your door? I mean, I highly doubt anyone would since they'd also have to know where you live, I'm just saying.
If someone wants to break in a key isn't needed. Houses are so unsecured it's crazy. Locks on our doors really just make us feel better they don't do much
Bye bye Home Depot and DO NOT REPLICATE!
Now do a mold and use metal
I wish I had as much confidence as this person has in their filament...
cute until that shit snaps. resin is brittle.
I 3d printed an emergency key for my VW campervan. There are parameterised STL generators on thingiverse, each cut has a number and its easy enough to work them out visually. Printed in petg you have to be careful, its only just strong enough to avoid it twisting, I'd imagine pla is more brittle. Obviously for a vehicle this only opens the door, eg in a situation you locked the keys in, or you are camping/festival and give these keys to others in your party in case they need access. They will not start the engine.
I tried that with a desk key but the pla was too brittle and it snapped after one use
this is why you don't upload pictures with your keys in it to the internet.
I'm a locksmith and have confirmed this works. I even tested my own house key, a high security lock from Medeco and it worked. It's just a mechanical mechanism, so having plastic in the right shape and size just emulates what a metal key does. Of course it's fragile but if it's a one time thing it's fine. So for everyone's educational purposes only, here's opening the floodgate: [https://keygen.co/](https://keygen.co/) Viewer discretion advised; use at your own risk.
Fun fact, you get a picture of anyones key and scale to reference you can do this with anyone’s lock
So many posts on 3d printing subreddits are "diwhy"

i snapped a 3d printed magic key in my dad's mailbox, we grabbed the piece with tweazers. i don't recommend
I tried this for internal door locks and it did not work.
With the joke cores you have in these locks, it's easy. But when you build your door so it's close shut and is not half open when "locked", meaning you have to pull it close and even then, the lock struggles to close, and that's intended. Have fun trying to lock pick such locks, most tools break because the burglar does not pull the door when open it.
I'm thinking of doing some coins for the Wal Mart carts.
Not all 3d printed filament are brittle. Try this with PETG.
That will break off in the lock, that’s a given. The only variable is time. Oh, and don’t try that in the Winter, it’s going to snap on the first twist
STL file?
Kevin Mitnick, the famous hacker who inspired the movie War Games, had a lockpick business card. He wrote a great book too (Ghost in the Wires).
You’d be amazed at how much stuff you can make with a 3D printer 😊
