Remote keyless entry system

The Remote Keyless Entry (RKE) system is a radio frequency system that allows the use of a remote battery- powered radio transmitter to control the power lock system. On vehicles with the RKE option, the power locks can be operated by depressing the Lock or Unlock buttons of the RKE transmitter. The RKE system includes an illuminated entry feature, which turns on the courtesy lamps for a timed interval (about thirty seconds), when the power locks are unlocked using the RKE transmitter.

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 system can retain the vehicle access codes of up to four transmitters. The transmitter codes are retained in memory, even if the battery is disconnected. If a transmitter is faulty or lost, new transmitter vehicle access codes can be programmed into the system using a DRB scan tool and the proper Diagnostic Procedures manual.

The RKE system consists of the remote key fob transmitter and a radio receiver with program logic.

The RKE receiver is installed in an RKE housing on the headliner of the vehicle, or in the housing of the optional overhead console, depending upon how the vehicle is equipped.

Following are general descriptions of the major components in the RKE system. Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the RKE system.
