Abstract

An electronic door lock is operable to control access to an access controlled area adjacent the inner side of a door. The door lock includes an outer base, an inner base, a locking mechanism movable between a locked and unlocked position in response to a control signal, and a control circuit disposed within the inner base and operable to generate the control signal in response to the presentation of an input credential. A plurality of different types of credential readers are each selectively attachable and removable from an attachment interface when the outer base is attached to the door to electrically connect the selected one of the plurality of different types of credential readers to the control circuit. The selected credential reader receives data from a user or credential and generates the input credential. A communication module is operable to communicate with a device separate from the electronic door lock.

7. The electronic door lock of claim 1, wherein the communication module is one of a wired communication module and a wireless communication module, each of the wired communication module and the wireless communication module being selectively removable and replaceable without disturbing the locking mechanism and without disturbing the control circuit.

8. An electronic door lock that mounts to a door, the door including an inner side and an outer side and the electronic door lock operable to control access to an access controlled area positioned adjacent the inner side of the door, the electronic door lock comprising:

an inner base supported by the inner side;

an attachment interface coupled to the outer side and including a mounting portion;

a locking mechanism coupled to the door and movable between a locked position and an unlocked position in response to a control signal;

a reader selected from a keypad, proximity detector, proximity detector with built-in keypad, magnetic stripe reader, magnetic stripe reader with built-in keypad, and biometric reader, each of the keypad, proximity detector, proximity detector with built-in keypad, magnetic stripe reader, magnetic stripe reader with built-in keypad, and biometric reader removably mountable to the attachment interface;

a control circuit coupled to the door and configured to selectively move the locking mechanism between the locked position and the unlocked position to control access to the access controlled area, the control circuit including software or firmware operable to receive input data from the selected reader, the control circuit further operable to generate the control signal in response to the input data; and
