Keyless Entry: Description and Operation

PURPOSE
The Remote Keyless Entry (RKE) module controls the following features:
1. Door lock/unlock feature
2. Luggage compartment unlock feature
3. Automatic door lock feature
4. Panic alarm feature
5. Illuminated entry feature
6. Battery saver feature

OPERATION
Door Lock/Unlock Feature
The doors may be locked or unlocked using the door lock switches, door keypad, or the transmitter. When the door lock switch is held toward "LOCK", ground is applied to the 119 (PK/Y) circuit. The RKE module then applies voltage to the 117 (PK/BK) circuit, causing the door lock motors to lock the doors. When the door lock switch is held toward "UNLOCK", ground is applied to the RKE module via the 120 (PK/LG) circuit. The RKE module then applies voltage to the 118 (PK/O) circuit, causing the door lock motors to unlock the doors.

Entering the factory permanent code or the owner's alternate code causes the RKE module to apply voltage to the driver's door lock motor via circuit 163 (R/O). Pressing the 3/4 button within 5 seconds causes the RKE module to apply voltage to circuit 118 (PK/O), causing the door lock motors to unlock the passenger door.

Pressing the transmitter unlock button causes the RKE module to apply voltage to the driver's door lock motor via circuit 163 (R/O). Pressing the transmitter unlock button a second time within 5 seconds causes the RKE module to apply voltage to circuit 118 (PK/O), causing the door lock motors to unlock the passenger door.

Luggage Compartment Unlock
The luggage compartment may be locked or unlocked using the door lock switches, door keypad, or the transmitter. Pressing the door keypad 5/6 button within 5 seconds of unlocking the driver's or passenger's door, causes the RKE module to apply voltage to the 118 (PK/O) circuit, causing the door lock motors to unlock the luggage compartment. Pressing the transmitter TRUNK button once (twice on some vehicles) causes the RKE module to apply voltage to the trunk release solenoid via the 84 (P/Y) circuit.

Automatic Door Lock Feature
The Automatic Door Lock (Autolock) feature allows the RKE module to automatically lock the doors when the following conditions are met:
1. Autolock feature is activated.
2. Driver's seat is occupied.
3. All doors are closed.
4. Ignition switch is in "RUN".
5. Gear selector passes through "REVERSE".

Autolock activation or deactivation is accomplished by performing the following steps:
1. Enter the permanent five digit code into the keypad.
2. Press and hold the 7/8 button within 5 seconds of performing step 1.
3. Press and release the 3/4 button within 5 seconds of performing step 2, while still holding the 7/8 button.
4. Release the 7/8 button within 5 seconds of performing step 3.

When the ignition switch is in "RUN", voltage is applied to the RKE module via the 298 (P/O) circuit. When the driver's seat is occupied, ground is applied to the RKE module via the 177 (W) circuit. When all doors are closed the ground signal is removed from the 465 (W/LB) circuit. If all of the above conditions are met, the RKE module looks for a momentary ground on the PRNDL input via the 140 (BK/PK) circuit. When the RKE module sees this signal, it momentarily applies voltage to the door lock motors via the 117 (PK/BK) circuit. The door lock motors then lock the doors.

Also, after the above Autolock operation, all the doors will be relocked whenever a passenger door is opened then closed. The doors would not be relocked if either the ignition is off at the time or the driver's seat switch is open for 3 seconds or more while the door is open.

Panic Alarm Feature
When the PANIC button on the RKE transmitter is pressed, the RKE module applies a pulsing ground signal to the 6 (Y/LG) circuit and a pulsing voltage signal to the 14 (BR) circuit. This forces the horns to beep and exterior lamps to flash. The RKE module will continue this action for a maximum of 3 minutes.

Illuminated Entry Feature
The illuminated entry feature may be activated by lifting a door handle or by pressing any transmitter key. When either of these is performed, the RKE module applies battery voltage to the interior lamps and keyhole illumination lamps via the 53 (BK/LB) circuit.

Battery Saver Feature
The RKE module supplies voltage to the convenience lamps circuit. When the RKE module receives an input signal it removes voltage from the convenience lamps 45 minutes after the last input is received.

Transmitter Programming
Before any of the RKE features will operate, the RKE module must be programmed to accept signals from the transmitters. The RKE module may be programmed to accept signals from up to four transmitters. The following steps must be performed in order to program or reprogram the RKE module to respond to the selected transmitters:
1. Put the ignition switch in "RUN" or "ACC" and momentarily jumper the two program connector terminals. The system will respond by locking and then unlocking all doors.
2. Press any button on the transmitter. All doors will lock and then unlock to verify transmitter signal acceptance.
3. Repeat step 2 to program the RKE module to accept up to four transmitter signals.
4. Turn the ignition switch to "OFF". All doors will then lock and unlock.
5. Operate a button on each transmitter to verify that the system has been programmed successfully.
