Remote keyless entry receiver

On models with the Remote Keyless Entry (RKE) option, an RKE receiver is mounted in an RKE housing, or in the overhead console housing on the vehicle headliner. The RKE receiver is a radio frequency unit that also contains the RKE system program logic.

The RKE receiver also performs as a smart relay for the illuminated entry feature.

The RKE receiver has a memory function to retain the vehicle access codes of at least one, but no more than four RKE transmitters. The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected.

The RKE receiver receives inputs from the battery, the driver door ajar switch, and the Chrysler Collision Detection (CCD) data bus. It also receives the radio signal input from the RKE transmitter. In response to those inputs, it is programmed to control outputs to the power lock motors, the courtesy lamp circuits, and the vehicle horn.

The RKE system for this vehicle also features a customer programmable horn chirp feature. This feature allows the customer the option of enabling or disabling the horn chirp request that the RKE receiver issues as an audible indication that a valid Lock signal has been received from the RKE transmitter.

See Remote Keyless Entry Receiver Programming in this group for more information on this feature.

The RKE receiver cannot be repaired and, if faulty or damaged, it must be replaced.
