An actuator-controlled electric strike for operating in conjunction with a spring latch of a lockset is provided. The strike comprises a housing having an entry chamber therein, and a spring latch keeper disposed in the entry chamber for movement between a keeper locked position and a keeper unlocked position. The spring latch keeper is rotatable about a keeper axis of rotation. The spring latch keeper includes: a keeper face configured for abutting contact with the spring latch when the spring latch is disposed in the entry chamber and the spring latch is in the engaged position; a second surface recessed from the keeper face, and a spring latch contact ridge positioned between the keeper face and the second surface, wherein the spring latch contact ridge is disposed at a non-perpendicular angle from the keeper axis of rotation.

An electronic door lock device and an electronic door lock provides electronic components on a strike plate side of a door frame rather than inside the actual door, which is a limitation to conventional electronic door lock devices. The unique design provides for flexibility in using standard doorknobs that otherwise could not be used in an electronic door lock. Electrical wiring connection need not involve the door itself for allowing flexibility in use of any door and for avoiding any disconnection of electrical wiring due to door movement when the door is opened and closed. An electromagnetic expansion block moves an auxiliary latch that locks a cam for preventing the doorknob from rotating when locked. The cam is in contact with a link strip that engages a locking tongue to lock the door. Alternatively, a blocking block moved by an electromagnetic module may be used to lock the cam.
