Abstract:
A pass-key electronic module for enabling a remote control system to activate a function of a motor vehicle equipped with an anti-theft system including a key identity sensor to transmit an identity code for validation to a vehicle control unit through a data communication link, comprising:(a) a receiver circuit for receiving a command to activate the function of the motor vehicle from the remote control system, and a request from the vehicle control unit to transmit an identity code; (b) a key identity sensor disabling circuit responsive to the command to activate the function of the motor vehicle to prevent the key identity sensor from communicating with the vehicle control unit; (c) a memory circuit for storing an identity code for validation by the vehicle control unit; and (d) a communication circuit connected to the data communication link for transmitting the identity code stored in the memory circuit to the vehicle control unit in response to both the command from the remote control system and the request from the vehicle control unit, wherein validation of the identity code from the memory circuit by the vehicle control unit enables activation of the function of the motor vehicle.
