SAFE-O-MAT locking systems for lockers from Hafele Australia  have been successful around the world.

SAFE-O-MAT locking systems are suitable for use with cupboards or lockers to provide safe, temporary storage.

The success of SAFE-O-MAT locking systems, can be attributed to the fact that the key can not be removed from the lock until a coin deposit is inserted. Only after the coin is inserted is it possible to lock the door and take out the key. When the locker is opened again, the coin is returned automatically and the key remains in the lock.
