Locksmithing/pinning a 6pinn medico lock


i do my nunbers take lowest number from change key then i subtract toget my master i cant figer out to get my drivers my change key works but not my master

Do your change key and master have the same angles?

If it is a mortise cylinder, pin it one chamber at a time while trying the key after each chamber.

You can do it with know cylinders but it can be a pain holding down the springs and trying the key.

Regular Medeco or Keymark?
