We all know how it feels to forget the keys somewhere and being unable to find them. That’s why, today we have a special tutorial for you in which we will show you how to make a spare key for the lock using only the key needed duplicate for, lighter, scissors and a can lid.

These steps are very simple but precision is required because if you cut the lid wrong, then the key will not work at all. Luckily, the good old Dave Hax is here to guide you through the process.

First thing that you need to do is to apply heat to the original key with the lighter to the point that the key will become black from the fumes.

Than take the key in your hand and lay it down on a piece of scotch tape, so that the marks from the fumes will be stuck on the tape. When you see clearly the shape of the key on the tape, just stick the tape on the can lid gently.

Be careful not to damage the traces. After you stick the tape on the lid, start cutting with the scissors carefully, on the edge of the traces. After you finish with cutting, try out the new spare key that you just made.
