Transmitter, Keyless Entry Remote
The keyless entry/computer operated lock system includes two four-button (hand-held) keyless entry remote transmitters. The transmitters are programmable and all the transmitters for the vehicle must be programmed at the same time. When diagnosis is carried out it is essential to have all transmitters to carry out the tests.

The key less entry/computer operated locks will not operate with the ignition switch in the ACC or RUN position.

To unlock the driver front door, press the UNLOCK button on the keyless entry remote transmitter once.

To unlock all doors, press the UNLOCK button on the remote transmitter a second time within five seconds of unlocking the driver front door.

To release the luggage compartment door press the blue TRUNK button on the remote transmitter.

To turn on the interior lamps and door lock cylinder illumination press either the UNLOCK, TRUNK or PANIC button on the remote transmitter.

To lock all doors press the LOCK button on the keyless entry remote transmitter once.

To confirm that all doors have locked, press the LOCK button again within five seconds of the first press. This will sound the horn and send another lock signal to the door lock actuators.

To activate the personal security alarm, press the red PANIC button on the remote transmitter. The horn will sound and the headlamps and center high mount stop lamp will flash.

To deactivate the personal security alarm, press the red PANIC button again or turn the ignition switch to the RUN position.

Electronic Door Lock Control Module
The electronic door lock control module contains a radio receiver that receives a signal from the keyless entry remote transmitter through the electronic door lock control module antenna. When a signal is received, the electronic door lock control module sends the appropriate command to the door lock actuators, the horn relay, the luggage compartment release actuator, central timer module, and the exterior lights.

The electronic door lock control module is equipped with battery back-up which maintains the programmed transmitter(s) memory in the event of vehicle battery disconnection.

Antenna, Electronic Door Lock Control Module
The antenna is a conventional co-axial cable which receives the signal from the keyless entry remote transmitter and relays it to the electronic door lock control module.

Security Mode Operation
The electronic door lock control module also controls the panic mode function.

Upon activation of the panic mode by pressing the keyless entry remote transmitter PANIC button, the electronic door lock control module sends a signal to activate the horn, flash the headlamps and the center high mounted stoplamp.

The electronic door lock control module cancels the panic alarm if the PANIC button is pressed again or the ignition switch is turned to the RUN or START position.
