Keyless Entry Transmitters

By operating any of the exterior door handle buttons, a nearby transmitter is challenged by a keyless entry antenna. The transmitter will send an RF response to the remote control door lock receiver, which communicates with the BCM. The BCM will interpret this communication and either allow entry into the vehicle or deny it. Transmitters programmed as number 1 or 2 will have certain corresponding features on equipped vehicles. For example transmitter 1 will activate the memory seat associated with that transmitter and the same for transmitter number 2. On vehicles equipped with approach logo lighting only transmitters 1 and 2 will activate the approach logo lighting.
