Abstract

A wireless access control system for a door may include a lock assembly carried by the door. The lock assembly may include a lock, lock wireless communications circuitry, a touch sensor, and a lock controller. The system may also include a plugin device remote from the lock assembly. The system may also include a remote access device remote from the lock. The plugin device may wirelessly send a lock communication enable command to enable the lock based upon wireless communication with the remote access device. The lock controller may communicate with the remote access device based upon wirelessly receiving the lock communication enable command, perform an authentication of the remote access device based upon the lock communication enable command, and switch the lock between locked and unlocked positions based upon the authentication and the user touching the touch sensor.
