  • Publication number: 20220145673
    Abstract: A push button lock mechanism is remotely and manually operable. The mechanism has a lock cylinder that is rotatable when a key is located therein; an actuator that is connected to the lock cylinder to be rotated thereby and that is biased toward an outwards position; a locking gear formed to be rotated by the actuator between a first position in which the actuator is prevented from passing therethrough and a second position in which the actuator can pass therethrough from the outwards position to an inwards position; a push button for linearly moving the actuator through the locking gear from the outwards position to the inwards position; and a remotely operable motor that acts to rotate the locking gear between the first position and the second position when operated. The motor can be remotely operated by a radio frequency fob or any other passive keyless operating device.
