ABSTRACT:
A keyless entry system is disclosed for use with a deadbolt latch mechanism on a door. The latch mechanism includes an arm having a slot for engaging and disengaging an associated deadbolt. The keyless entry system comprises an interior portion, an exterior portion and a drive arm connecting the portions. The interior portion has a housing mounted on the door. The housing has a base plate with a first opening aligned with the slot. A camlock with a ratchet is rotatably mounted on the base plate, the camlock having a second opening aligned with the first opening and the slot. A solenoid with a slug is also mounted on the base plate. The slug has a retracted position and an extended position with the slug engaging the ratchet in the extended position to prevent rotation of the camlock. An electronic controller is mounted on the base plate in electrical communication with the solenoid. The controller moves the solenoid slug from an extended position to a retracted position in response to entry of a coded sequence. The exterior portion comprises a linkage and a keypad in electrical communication with the electronic controller for manual entry of the coded sequence. A drive arm extends through the first and second openings and rotates in conjunction with the camlock and operably engages the slot of the latch mechanism. The drive arm is connected to the linkage and is rotatable thereby when the slug is retracted.
