Abstract: A lock, particularly well suited for installation in the T-handle of a vending machine or the like, which acts as a spring latch during opening and as a deadbolt in the locked position. The lock has a cylinder with a rotatable plug supporting a drive pin, the drive pin being parallel to and offset from the axis of plug rotation. The drive pin engages a ramped guide groove in a spring biased bolt, the guide groove being configured to return the drive pin to a position where it is in registration with, but displaced from, its starting position after a complete rotation of the plug.
