How to unlock any combo lock with a can

Have you ever had a lock at home or on your bike that you forgot the combo to?
You then had to go and get a bolt cutter to destroy the lock and we all know that takes forever if you can even find one! Here I will show you how to make a lock picking device using only a metal can and scissors!

Step 1.

Find a metal can.
I started this series with a beer can but ended up cutting myself badly so I finished with a new ice tea can. You will notice the pictures switch half way in.







Step 2.

CAREFULLY cut the can top and bottom off like so.. Please be very careful not to cut yourself.







Step 3.

Next step is to cut the shape out.
Draw a M shape on the rectangle with a marker. The M should start out a quarter from the left of the square and should be about half a inch up from the bottom. It should curve down so the bottom part is a half inch in from the left and should look like this.








Step 4.

Simply cut and fold the can as shown in the picture. Use a ruler or something flat to flatten out the folds.









Step 5.

The best method to open it is to have the part of the shim that will go inside the lock on the outside of the bar. Push it down into the padlock, and then twist to unlock it. It can be very hard to master, don't give up. It will probably take a few minutes to get it to work. These are only good for a few uses, because they begin to crumple up and will no longer fit in the lock. A good practice technique is to use an open lock, look inside at the part you are trying to force open, and try moving it while the lock is open to see what you need to do when it is closed.
