Given some isolation from prying eyes, a good non-technical method of making a key is to use a blank and grind it by hand. By binding the cylinder and wiggling the key, it leaves marks for each pin that is bound up; grind a little and repeat. Obviously not going to work for certain lock styles with security pins, or Medeco locks (but nor will audio work either, unless you can somehow hear a pin rotating a specific direction)
- Chirael 6y agoFor anyone who’s interested in this, it’s called impressioning and is really cool. It basically uses the design of the lock (pins pushed down into the keyway by springs, preventing the cylinder from turning) in the attack by using the marks those pins make on a key, to gradually fashion a working key.
