General Description

Remote Keyless Entry (RKE) System:




Remote Keyless Entry (RKE) is a feature which allows for the operation of the door locks, and interior lighting from outside the vehicle.

The remote keyless entry (RKE) system consists of a Body Control Module (BCM) and two transmitters. The BCM can be programmed with up to four transmitters. The transmitter sends a signal to the BCM when lock, unlock, and panic button is depressed. The BCM interprets the signal, decodes it and then executes it by activating the required circuitry to provide the requested function.

The Saturn Security System is a feature that is operated from the RKE transmitter. The Saturn Security System provides content theft protection by sounding the horn and flashing the DRL lamps if a door is opened or the ignition lock cylinder is turned. This system does not disable the vehicle.
