Keyless Entry: Description and Operation

Two different Remote Keyless Entry (RKE) systems are offered on this model. One system is used on vehicles that are not equipped with the optional Vehicle Theft Security System (VTSS), and a different system is used on models that are equipped with the VTSS option.

Both RKE systems are radio frequency systems that allow the use of a remote battery-powered radio transmitter to control the power lock system. Both RKE systems include an illuminated entry feature, which turns on the courtesy lamps for a timed interval (about 30 seconds), when the power door locks are unlocked using the RKE transmitter. ON both RKE systems, the power locks and illuminated entry can be operated by depressing the Lock or Unlock buttons of the RKE transmitter. If the vehicle is equipped with the optional VTSS, the RKE transmitter also arms and disarms the factory-installed vehicle theft alarm.

The only visible difference between the two RKE systems lies in the location of the system control circuitry and logic, the RKE receiver, and the illuminated entry system relay. Models without the VTSS option have their RKE system control components and receiver integral to the power lock and Remote Keyless Entry (RKE) module. Models with the VTSS option have their RKE system control components and receiver integral to the Central Timer Module (CTM). However, the CTM-based RKE system offers several additional features that are not available with the power lock and RKE module-based system. See Power Lock and Remote Keyless Entry Module, and see Central Timer Module for more information.

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