Keyless Entry: Description and Operation

The transmitter signal (frequency) is stored in the receiver assembly's non-volatile memory. However, the memory will be erased if the programming connector is grounded.

The remote control door lock receiver assembly is battery fed and is always monitoring the transmitter signal. When the correct transmitter signal is received to lock the front and rear side doors, a transistor driver will energize the correct lock control relay coil. The receiver assembly will also control which lock control relays will be energized to unlock the front and rear side doors, or release the rear compartment lid assembly or end gate window assembly.
