Keyless Entry Transmitters

2007 Cadillac XLR BaseSECTION Keyless Entry Transmitters

The keyless entry transmitters are used to passively or actively lock and unlock the vehicle. When any one of the 4 allowable programmed key fobs are challenged by a keyless entry antenna by depressing either of the exterior door open switches, the transmitters will passively send an RF signal to the remote control door lock receiver (RCDLR) via the door antennas. The RCDLR will then interpret this communication and either allow entry into the vehicle or deny it.
