How to Copy a key with a Coke can

This is a how-to video explaining how to copy a key with a can of cola. All you need is an aluminum soda or beer can. To make it come out better, add a additional side to the one piece. This technique works well when you don't have time to get a new key cut. Watch this video tutorial and learn how to duplicate a key with a Coke can.


Would it really be strong enough?

Is it really to week?

Cas it looks really week!

Can't seeing it getting you out of trouble

I'll try it over the weekend. There are a couple of doors I wouldn't mind opening...

You would need the orginal Coder...

doesnt work , i tried it, the aluminum is too weak to turn a lock

it pushes the pins up.. you only need an extra piece to turn it

the turning piece is called a torque wrench, you can use a flat head screw driver for that

Man this whole vidieo was a waste of 1 minut and sevon seconds. :~(

man, then what the #$%@ are you doing on the internet?

it would probobly get stuck and you would pretty much be screwed

2 layers might not be sufficient enough, i would recommend 3 layers or even 4...think about the thickness of the original key, it is at least as thick as 3 or four layers....

its very weak

why even bother, when you can just go get a key copied?

Maybe if you dont have enough money or time.Duh


thats not as Mc Gyver-esq

if you look at the video at the end where he use's the key, it looks like the normal key with a round bit of coke can stuck to the end

Nah... might work the more you layer the key

Nice. Personally more work than a $1 is worth.

But for backup keys for serialized keys (Master lock, ...) that can't be copied legally by a locksmith, this is an excellent alternative.

A small screwdriver could assist in providing the torque needed to turn stubborn locks.

I would probably make the folds first and then use an Exacto knife to cut the tumbler lands afterwards. There are only 0.023" difference between each of 6 tumbler locations.

To accurately cut these surfaces with scissors or a knife would be time consuming.

Most anywhere will copy any key that you have. The eceptions are not for Master Locks. Master Lock is a cheapo brand name that you use to lock your bike. The keys you can't get copies of are for locks like Medico. The only time you would see a Medico key is on the doors to your work place. Basicly, if Home Depo or Walmart can copy it, anyone will. Home use.

iv already tryed it itz to weak

Add more layers it worked for some people.:)

good.. now i can make a copy of that apartment gym key

The copy would just move the pins above the shear line. Then you could use a screwdriver or something hard and small to turn the tumbler. [for all you complainers of weak turning ability]


There is a great how to make a bump key video on WHT, that might be a more successful route to take; I wouldn't mind keeping one of those on my keyring.

Is it really to week?

i wonder if a thicker can like a slimfast can would work better

if u use a thicker can then it will be harder to cut out and also shape the ridges in the can.

Just get a bunch of cans .Then make the same key over and over again.take some super glue and glue it or hold it together.Simple.

I do not work at all

then get a job

does the crop after the yielding process taste better with organic nutrients?

the aluminum is too weak and on top of that your gonna rip the top of the fake key off leaving your door stuck until you find a way to get it out

try using a steel can instead of aluminiumand still doubleing it as above mentioned

How many more times do people have to say... It will be to thick to add the ridges! n00b

Smart smart we have a smart on here.Listen to him hes right itll be to hard and thick,its STEEL that is some hard metal.

Use the multiple copy key method above. Then use tempering to harden the individual slices of aluminum that have been preshaped and clamped together. at that point the "Accelerated Aging" of the alloy will harden it as its repeatedly heated and then immediately cooled. it'll be harder than the original and work for even side indented tumbler keys as well.

Necrit, if you do that the aluminum will be as brittle as a Dorito chip. I was a locksmith for 6 years. To anyone who tries this key making thing I say to you, don't wast you f**n time. For the average Joe Thinking about doing it, prepare to be disapointed as your time Should be more valuable, unless you are just plain board. Go to Home Depot and get the key copied. If you can't afford the 2 bucks then you are too young to get into what ever it is you are trying to covertly get into IE: Gun and liquor cabnets. Get a job, stay out of trouble.

ok, i saw the video and the can aluminum does look to week, so this weekend i am going to tri it and i'l get back to you all with tha review. And if doesn't work, i'l try something else and tell you guy, and chicks.

it dosent work the key breaks inside the lock and you cant get it out it dosnt work i happend to me

it does not worck, i tried it with a blank CD and i was crying of joy... (literary)
a blank CD works best!!!

in some cases it may take pins to shear line but no doubt youll need a tension bar or something similar to rotate the cylinder.. thats whats really going on and i havnt even tried it!!! its matter of simple logic fool!!!

what if the duplicated key is not the problem but the door/locked that your trying the duplicated key on is the problem?

just put the key on the can and cut that out instead of outlining it u wil cut much more precisely

I tried this trick. Did it as precise as possible. but still didn't work. the key is just too weak made out of that flimsy tin. :(

When I made this copy and tried to test it (on the door to my bedroom), I got the handle broken off and the main part stuck in the lock

You can use an old credit card or a tic tac plastic can instead.
