Sometimes it is simply catastrophically necessary to make a spare key just in case of fire. A copy of the original just do not work out, for this you need specialized equipment. But what if you need a copy for a one-time opening of the lock? I will show you an incredibly easy way to make a duplicate in 10-15 minutes at home without any special machines and devices.
You will need
A disposable lighter.
A piece of tin from a tin can or from a lacquer tin.
Make a duplicate key from a piece of tin
This method is suitable for flat keys. Usually, the teeth are asymmetrical and adjacent to one side. Light a cigarette lighter and smoke this side. The key itself is better to hold the pliers or just a cloth, reeled in several times. The main thing is not to get burned. The whole plane of the working area needs to be smoothed.
Next, give the key to cool. Be sure to completely reach room temperature. Then cut off a piece of narrow adhesive tape and glue it to the surface where the soot was formed. Smooth from the top with your finger. Carefully tear off the adhesive tape and see that the imprint of the key is pretty clearly left on its sticky surface.
Then take a flat piece of tin from any jar and glue on top a strip of scotch with a print.
We take scissors and cut out the outline by fingerprint. Carefully cut out each tooth. The work is not very painstaking, as it may seem at first glance.
For any one when cutting a key, thin tin was wrinkled.To fix this, we trim the pliers.
