ABSTRACT:
A device allowing engagement of a conventional keyed deadbolt lock tumbler assembly without use of a key is provided. The device is assembled around the tumbler assembly and is fitted into a standard:door lock cut-out. The device includes a rotatable ring extending substantially around the periphery of the device. At rest the rotatable ring is biased in an original starting position. Upon overcoming the bias, the rotatable ring is moved to a second engaging position. Upon release of the rotatable ring the ring is biased back to the original position, while at the same time the deadbolt remains engaged. The biasing back of the device prevents the lock from binding or jamming.
