Hi StabbyGypsy!
I have an ideia.
First off: You need to decide if you want to have a lock that any key will open like MacGyver101 said (much easier), or you would like a lock that ONLY that key opens.
In order to do that, you need to get your hands on the original key. When you do, go to a locksmith to make a copy and return the original to it's place without her noticing it. That way you can work on it easily.
If that's impossible, stick to the idea of taking pictures of it but remember to have a ruler or something to measure it in the photo. You can also draw it in a piece of paper using the key as a template.
Then, go to a locksmith and see if he can build a lock for that key (it'll be cheap).
Or, if you already have a box with a lock, see if he can change it to fit that key.
He if can't, or wont, or you find that it has more meaning you doing it, get a couple of locks the same kind. Disassemble them (

Now in order for the key to work, you can do it like this (you really have to have a hard copy of the key for this):
- Insert the key in the lock
- Start placing the pins (the ones with a tip) in the holes (tip goes down) on the top of the plug
- Be sure that with the key in place, the top of the pins align EXACTLY with the the plug
- If they don't and you have no pin that does, file down a little a bigger pin until it does (remember, it has to align EXACTLY)
- Reassemble the lock and test it.
You can always get 4 or 5 locks and probably you will have all the pins you need.
If it works, you're set!
Any questions feel free to post them as we are pleased to help you.
And don't forget to take pictures of the process!
Be safe!
P.S. - I don't know how much you understand of locks so I tried to break down every step
P.P.S. - By the way, GREAT IDEIA dude!
Go ahead, keep plugging away, picking on me! You will end up on bypass or with rigor mortise.
