ABSTRACT:
A barrel lock includes a circumferential axial pin tumbler arrangement housed in the barrel. A removable pilot post is disposed among the tumblers and has key-guides which register with mating key-guides on an actuating key. To change the lock combination, the lock can be reassembled with the pilot post located in a new rotational orientation relative to the tumbler arrangement. A particular application includes locking merchandise compartments in vending machines, for example.
