A lock actuating device for a lock mechanism of a lock has a transceiver (309) capable of interaction with a wireless key device, a controller (313) coupled to the transceiver and capable of generating a control signal (307a), and a lock actuator adapted for actuation of the lock mechanism upon receipt of the control signal from the controller. The controller (313) has a sleep mode and an operational mode. The lock actuating device also has a wake-up arrangement (320) including a sensor (324) and associated circuitry (322). The sensor (324) is positioned to detect the presence of a user in a vicinity of the lock actuating device. The circuitry (322) is adapted to generate a wake-up control signal (326) to the controller (313) upon detection of the user, so as to cause the controller (313) to switch from sleep mode to operational mode. |
