Sometimes it is simply catastrophically necessary to make a spare key just in case of fire. A copy of the original just cannot be done, for this you will need specialized equipment. But what if you need a copy for a one-time opening of the lock? I will show you an incredibly simple way to make a duplicate in 10-15 minutes at home without any special machines and accessories.

Will need


  • Disposable lighter.
  • Narrow tape.
  • Scissors.
  • A piece of tin from a tin can or from a paint can.
  • Pliers.
