Description & Operation

Remote Keyless Entry (RKE) system allows for locking and unlocking of the vehicle doors by remote control, using a hand-held radio transmitter. The RKE receiver module, which is integrated into the Body Control Module (BCM), may receive signals from up to 4 transmitters. Each transmitter has its own ID and a rolling code which is stored in BCM memory. The ID of each transmitter never changes. The rolling code changes each time a button is pressed. If the transmitter is replaced, or another added, the code from all units has to be programmed into BCM memory.

The transmitter will operate within approximately 23 ft. (7 m) of the receiver. If the transmitter button is pressed more than 250 times out of vehicle range, rolling code will go out of synchronization and must be re-synchronized by pressing any transmitter button twice. The receiver is capable of retaining memory even when power is removed. The transmitter has 2 replaceable 3-volt batteries (CR2016).

Pressing UNLOCK button once unlocks driver's door and enables illuminated entry. Pressing UNLOCK button twice within 5 seconds unlocks all doors. When LOCK button is pressed, horn will sound, signaling that "lock all doors" signal was received and set. Illuminated entry operation is canceled and all interior lights will turn off. When PANIC button is pressed for more than one second, panic mode is enabled. Driver's door unlocks, interior lights come on, the horn sounds and headlights flash approximately once per second. Panic mode can be cancelled by pressing UNLOCK button or will reset after three minutes.
