Introduction: How to Make a Simple Duplicate Key

I show how to make a simple duplicate key that can be made from a plastic card, a tin can or any other similar material. This can be used as an emergency spare key. The first step is to use a lighter and clear tape to make an outline of the key with the exact dimensions of the original. The outline of the key is on the clear tape which can be transferred to a plastic card or the lid of a tin can. The key is then cut out as precise as possible and can be used to open the lock. It may be too flimsy to turn so you can use a small Flathead screwdriver or a lockpicking tension wrench to turn the key. On stiffer plastic you may have to bend the key to make it fit into the key-way better. It is very easy to make a duplicate key this way and can be done in a few minutes. Be careful to make the teeth of the key as accurate as possible so it does not get stuck in the key-way. Only open locks you own or have permission to open.

Lock picking is the art of unlocking a lock by analyzing and manipulating the components of the lock device without the original key. In addition, ideal lock picking should not damage the lock itself, allowing it to be re-keyed for later use, which is especially important with antique locks that would be impossible to replace if destructive entry methods were used. Although lock picking can be associated with criminal intent, it is an essential skill for a locksmith, and is often pursued by law abiding citizens as a useful skill to learn or simply a hobby.
