REMOTE KEYLESS ENTRY TRANSMITTER
The Remote Keyless Entry (RKE) system transmitter is equipped with three buttons, labeled Lock, Unlock, and Panic. It is also equipped with a key ring and is designed to serve as a key fob. The operating range of the transmitter radio signal is up to 7 meters (23 feet) from the RKE receiver.

Each transmitter has a different vehicle access code, which must be programmed into the memory of the RKE module in the vehicle in order to operate the RKE system. See the procedures for RKE transmitter programming. (Refer to POWER LOCKS/REMOTE KEYLESS ENTRY TRANSMITTER - STANDARD PROCEDURE - TRANSMITTER PROGRAMMING).

The RKE transmitter cannot be repaired and, if faulty or damaged, it must be replaced. The batteries for the RKE transmitter are available for service replacement.

The Remote Keyless Entry (RKE) transmitter is a radio frequency transmitter that operates on two Panasonic CR2016 (or equivalent) batteries. Typical battery life is from one to two years.

POWER LOCK SWITCH
The power lock system is controlled by a two-way switch that is integral to the Driver Door Module (DDM) and the Passenger Door Module (PDM), mounted in the trim panel of its respective front door. Each switch is illuminated by a light-emitting diode when the ignition switch is turned to the ON position.

The power lock switches and their lamps cannot be repaired. If the switches are damaged or faulty, the entire PDM or DDM unit must be replaced.

The power lock switches provide a hard wired Lock and/or Unlock signal to the power lock system control circuitry, which is located within the Passenger Door Module (PDM).

REMOTE KEYLESS ENTRY MODULE
On models with the optional Remote Keyless Entry (RKE) system, an RKE module is mounted in the mini-dome lamp housing, or in the overhead console housing on the vehicle headliner. The RKE module contains a radio frequency receiver and the RKE system program logic. The RKE module also serves as a smart relay to control the illuminated entry feature included with the RKE system.

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

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 module issues as an audible indication that a valid Lock signal has been received from the RKE transmitter. (Refer to POWER LOCKS/RE- MOTE KEYLESS ENTRY MODULE - STANDARD PROCEDURE - MODULE PROGRAMMING).

The Remote Keyless Entry (RKE) module receives inputs from the battery, the driver door ajar switch, and the Chrysler Collision Detection (CCD) data bus. It also receives the radio frequency inputs 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 horn relay.

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