A door lock (1), preferably operable both by a mechanical key (C) with a key cylinder (60) and by an electronic signal and having inside and outside handles (A, B) mounted on inside and outside hollow spindles (10, 50), for mounting on a door having an inside face and an outside face, has a cylindrical lock chassis (80) with a provision for retracting a latch bolt (4) in response to rotation of either of the hollow spindles (10, 50); a member (40) for selectively locking the outside spindle (50) against rotation; a reversible electric motor (20) mounted coaxially within the inside spindle (10), the motor being secured against rotation but free to slide axially against resistance provided by a biasing member (21), and having a motor shaft (31) extending through the cylindrical lock chassis (80) to operably engage the member (40) for locking the outside spindle (50); a power supply (101) for the motor (20); and a mechanism (42, 45, 61) for selectively moving the member (40) between locked and unlocked positions.

[ We claim:] [1.] A door lock, operable by an electronic signal and having inside and outside handles (A, B) mounted on inside and outside operators respectively and having a locking means for moving a latch bolt (4) from an extended position to a retracted position, the locking means being engaged

[ We claim:] [1.] A door lock, operable by an electronic signal and having inside and outside handles (A, B) mounted on inside and outside operators respectively and having a locking means for moving a latch bolt (4) from an extended position to a retracted position, the locking means being engaged with the operators, the inside and outside operators being rotatable from a first position wherein the latch bolt (4) is in an extended position to a second position wherein the latch bolt (4) is in a retracted position, the door lock comprising:a housing (80);means for preventing rotation of the outside operator; anda reversible electric motor (20, 102) mounted within the housing (80), the motor (20, 102) being secured against rotation but free to slide axially against resistance provided by a biasing means (21, 109) and having a motor shaft (31, 106) extending therefrom to operably engage the means for preventing rotation, the motor (20, 102) moving the means for preventing rotation between an unlocked position wherein the outside operator is free to rotate and a locked position wherein the outside operator is locked against rotation.
