For 1990-2009 cars

### Unlocking the Doors

1. Press the UNLOCK button once in order to perform the following operations:

• | Unlock the driver's front side door

• | Turn on the illuminated entry

• | Disarm the universal theft-deterrent system

2. Press the UNLOCK button a second time, within 5 seconds, in order to unlock the passenger door.

### Releasing the Rear Compartment Lift Window Panel

1. On vehicles with an automatic transmission, perform one of the following operations:

• | Place the vehicle into the PARK position.

• | Turn the ignition to the OFF position.

2. On vehicles with a manual transmission, perform both of the following operations:

• | Turn the ignition to the ON position.

• | Set the park brake.

3. Press the button marked with the vehicle symbol in order to perform the following operations:

• | Release the rear compartment lift window panel

• | Activate the illuminated entry

### Locking the Doors

Press the LOCK button in order to perform the following operations:

• | Lock all of the doors

• | Deactivate the illuminated entry

• | Arm the universal theft-deterrent system

### Panic Mode

### Remote Control Door Lock Transmitter

The remote control door lock transmitter transmits a radio signal to the body control module (BCM). The BCM controls the functions of the transmitter. The transmitter range is approximately 9 m (30 feet).

The transmitter data is encrypted, and changes with each use. If the transmitter buttons are pressed too many times out of range from the vehicle the transmitter and the BCM will get out of synchronization. This will result in the transmitter appearing not to work at all. This situations will occur after the transmitter button is depressed more that 256 times when it is out of range from the vehicle. This may also be necessary if the transmitter battery has been replaced and the buttons were pushed a few times out of range. If the transmitter and the BCM get out of synchronization, re-synchronize the transmitter and the BCM. Refer to Re-synchronizing Transmitter and Body Control Module.

### Re-Synchronizing Transmitter and Body Control Module (BCM)

Press both lock and unlock on the transmitter and hold for approximately 8 seconds. This will attempt to match security codes.

### Body Control Module (BCM)

The Body Control Module (BCM) is battery fed. The BCM is always monitoring the transmitter signal. When the BCM receives the correct transmitter signal the following actions occur:

1. A transistor driver energizes the correct lock control relay coil.
2. The transistor driver will arm the universal theft-deterrent, if equipped.
3. The doors lock.

The BCM also regulates which lock control relays will be energized in order to perform the following operations:

• | Unlock the doors

• | Release the rear compartment lift window panel

• | Disarm the universal theft-deterrent, if equipped

For replacement of the BCM, refer to Body Control Module Replacement
