ABSTRACT:
The present invention provides new door lock combination chambers for use with door locks, particularly pushbutton door locks. The combination chamber includes rotary keys which are actuated by pressing pushbuttons when entering an unlocking code into the combination chamber. The rotary keys rotate and engage idler gears which are engaged with a timing gear and code gears. The code gears have pockets which become aligned with an unlocking slide when the proper unlocking combination is entered into the combination chamber. The unlocking slide can be slide into the pockets on the code gears, and thus allow a corresponding locking mechanism retract a latch bolt in a door.
