The 3D printed version could, however, be used to create a mold to cast a more robust replica.
Here’s one way to make a mold.
Lead and cadmium? Jeez
Most locks don’t really keep people out. They just keep honest people honest. At best, they slow an attacker down and/or make it more obvious.
This jams the lock! :D
It would work a couple of times. It’s just not a long term solution.
Only if the lock isn’t worn or dirty on the inside. I wouldn’t trust this for any outdoor lock or older lock. Even cheap locks with poor fit and finish causing rough operation would not be a good idea. This is a fun gimmick that could easily cost you more money than it’s worth.
The only way I might use it is if I were to use the 3D printed key as a pattern to cast a metal one. And I ain’t got time for that.
I personally think it would hold up, so long as it wasn’t abused. 3D prints are weak and prone to breaking with in the inter layer structure. Intra layer, they are quite strong. Also when they fail, intra layer, they tend to deform, rather than snap.
Material matters however. PLA is relatively prone to breaking. PETG or nylon are far tougher.
It’s also worth noting the use case here. It’s either nefarious (breaking in) or one-off (unlocking a door where you no longer have the key available). Neither requires long term survivability.
I’ve had one of these 3d printed keys in my wallet as a backup in case I get locked out for 5 years now. I certainly don’t use it often but yeah it holds up fine.
The couple of times I have used it works fine but you certainly want to be a little extra careful with it. I’ve got locks that are only 5ish years old so they all turn rather easily, and I avoid my door with the deadbolt when I use it because that would probably be too much for it.
Mine is PETG but for how thin it is, it flexes a lot. I figured flexing is better than snapping off, but I think PLA or maybe a polycarbonate would function better. A nylon would probably be too flexible like the PETG.
Old locks can be brutal to keys, it’s what grinds the steel keys down & at some point even new keys don’t last as long.
I fully agree, but most locks aren’t in that state. 95% of the locks you might want to use this technique on would be in a reasonable condition.
Yes, I agree, it’s perfectly fine - jamming the door is more of a phobic anxiety.
Then again, 95% of such locks are prob vulnerable to simpler attacks.
This certainly doesn’t make me want a flipper any less than I already do. Seems so fun to mess with
After pen testing a home network it becomes a novelty item.
Turning off TVs and opening Tesla charging ports is fun for a bit.
The best, though, is setting off the department alerts at Walgreens, there’s a lot that exist that the employees have never heard. When you trigger “help needed in the baby department” then watch the employee reactions it’s a fun time.
Beyond that, it’s a paperweight most days.
I have a buddy that uses his to spoof people’s apartment swimming pool access cards.
Think of it like one of those 3-inch swiss army knives, but for IR tech and radio. If you mean to do work. Use the correct tool for the job, but there is no reason you cant acomplish what your trying to do. They are great for learning, if I was teaching a kids about cyber security, a flipper zero would be on the required tool kit.
Yes, you can do harm with them, per the previous analogy its still a knife. However, devices not hardened against simple replication attacks or brute force acomplished by something barely more powerful than a TI-84, those manufactures and customers needs to take the security of their products more seriously.
It was nothing more than a novelty after about a day and a half, even with the WiFi module.
I saw the video too and I found it somehow stupid to 3d printing a key when you can go to locksmith
If you’re copying keys like this, you probably don’t want a paper trail or additional witnesses.
if you have a 3D printer it
deniessaves you a trip to the hardware storeplus you could print fun… novelty keys. ( ͡° ͜ʖ ͡°)
you could even print them from dissolvable filament so that if your idiot guests lose them outside they’re likely to dissolve in the rain
or maybe there is such a thing as self destructing filament that doesn’t require water? like some kind of heat activated depolymerizer that takes a few days to break down after printing. that could be really useful for like an AirBnB
There’s a chocolate printer 🤷
Im interested in how a flipper can help? Is it some app that tells you how high the pins are?
Yes it has a key copy feature, it’s a key graph.
