Do you want to quickly copy a key ?

You can do it within 5 minutes using a soda can !

Simply trace the key on the can, cut it and mark the grooves using a pen.

Make sure that the perpendicular part at the beginning of the key is exactly at the same place. It is the part that stops the key at the right place 😉

You also may need to add another piece of metal at the top to get a stronger key.
