Remote Keyless Entry (RKE) System Operation The Remote Keyless Entry (RKE) transmitter functions work up to 30 feet (9 m) away from the vehicle. There are other conditions which can affect the performance of the transmitter. See Remote Keyless Entry (RKE) System on page 2-3. Programming Transmitters to the Vehicle Only RKE transmitters programmed to this vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer/retailer. When the replacement transmitter is programmed to this vehicle, all remaining transmitters must also be reprogrammed. Any lost or stolen transmitters will no longer work once the new transmitter is programmed. Each vehicle can have up to four transmitters programmed to it. Battery Replacement The battery in the transmitter is weak and should be changed if it does not work at the normal range in any location. LOCK: Press to lock all the doors. The parking lamps may flash and the horn may chirp. If a door is open or ajar when LOCK is pressed, the doors lock, but the theft-deterrent system does not arm until the open door is closed. L (Panic): Press to activate the alarm. The horn sounds and the headlamps and taillamps flash for up to 30 seconds. To turn the alarm off press Lagain, start the vehicle or wait 30 seconds.
