OEM PACHISLO Slot Machine Door Lock / Key 3-3/8" J1 Hook. Thick key, will not snap. For most newer pachislo machines. NOTE: WILL NOT FIT SAMMY MACHINES unless it is an exact replacement. If you have a Sammy machine let us know and we will recommend the appropriate lock. If you have the same lock but different hook, let us know the hook you need and we will see if we can replace the existing hook with the one you require. Take a close look at the bottom of the mech and see the metal insert. TO OPEN DOOR WITHOUT A KEY: Refer to the EVERYTHING PACHISLO Manual available on our store.
