Keyless Entry: Description and Operation

The electronic door lock control system has two main components: the Remote Keyless Entry (RKE) module with integral receiver, located behind the B-pillar on the driver side, and the three-button (hand-held) keyless entry remote transmitter.

The RKE module performs the following functions:
- Unlocks the driver front door.
- Unlocks all doors.
- Locks all doors.
- Turns on the interior lamps after either front door handle is lifted.
- Turns on the interior lamps when using a keyless entry remote transmitter.
- Activates and deactivates a personal security panic alarm feature that sounds the horn and flashes the parking lamps and headlamps.
- Activates the lock verify feature that sounds the horn when the lock button is pressed on the keyless entry remote transmitter twice within five seconds.
- Remembers to lock the sliding door if the door locks are activated when the sliding door is open.

The electronic door lock control system receives input from the following:
- Front door handles.
- Ignition switch.
- Door lock switch.
- Program connector.
- Lamp switch.
- Keyless entry remote transmitter.

The system distributes output to the following:
- Interior lamps.
- Power door lock actuators.
- Horn Relay.
- Headlamps.
- Parking lamps.

The electronic door lock control system is supplied with two, three-button, hand-held keyless entry remote transmitters.

The keyless entry remote transmitters have three different shaped buttons, with icons used to identify the lock, unlock and panic features.

NOTE: The electronic door lock control features will not function when the key is in run or accessory.

To unlock the driver front door, press the unlock button once on a keyless entry remote transmitter that has been programmed into the RKE module.
To unlock all doors, press the unlock button on a keyless entry remote transmitter twice. The second press must be within five seconds of the first. If more than five seconds have elapsed since the first press of the unlock button, pressing the unlock button again will only unlock the driver front door.

To turn on the interior lamps, press the unlock button.

To lock all doors, press the lock button on a keyless entry remote transmitter once. If the sliding door was open during the lock operation, the memory lock feature will activate to lock the sliding door after it is closed again. Pressing the lock button a second time within five seconds will lock the locks again and activate the lock verify feature which will provide a chirp" from the horn.

To activate the personal security alarm, press the panic button on a transmitter. The horn will sound and the parking lamps and headlamps will flash for a maximum of three minutes. Activating the panic alarm also illuminates the interior lamps.

To deactivate the personal security alarm, press the panic button on the same keyless entry remote transmitter that was used to activate the alarm, or turn the key on.

The RKE module will erase all previous keyless entry remote transmitters from memory when the keyless entry remote transmitters are programmed or reprogrammed.

NOTE: The RKE module can store up to four keyless entry remote transmitters in memory.

When troubleshooting the electronic door lock control system, it is essential that the customer leaves at least one keyless entry remote transmitter with the vehicle.

If the customer has purchased additional keyless entry remote transmitters, lost one, or if one must be reprogrammed into the RKE module, all keyless entry remote transmitters must be available for reprogramming at the same time.
