Door lock

Programmable automatic door locks:
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.

When the automatic door lock feature is programmed to control the door lock system, the BCM will lock the vehicle doors if the following inputs are true:

Ignition 1 input is active.
All door jamb switch inputs are inactive.
Cargo door or lift gate/lift glass ajar inputs are inactive.
Transmission is shifted out of park

This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the BCM will lock all doors again.

Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.

Transmitter Programming

With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Release the power unlock button on the door panel.

The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:
6.1. Locking the doors
6.2. Unlocking the doors

IMPORTANT: All extra transmitters must be programmed at this time. When a new transmitter is programmed, it will deactivate the old transmitters.

Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:

7.1. Locking the doors.
7.2. Unlocking the doors.

Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
In order to reprogram the remote control door lock transmitter with a scan tool, refer to Scan Tool instructions.

Transmitter Synchronization

Due to the security method used by the remote keyless entry (RKE) system, the transmitter may have to be synchronized. The RKE transmitter does not send the same signal twice to the receiver because the receiver will not respond to the same signal twice. This prevents the signal from being recorded and retransmitted.

Synchronization will be necessary if one or more of the following conditions apply:

The transmitter battery is very weak.
The transmitter is replaced.
The vehicle battery is very weak.
The vehicle battery is replaced.
The vehicle battery is disconnected.

Synchronize the transmitter with the receiver as follows:

While standing close to the vehicle, simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds.
The door locks should cycle in order to confirm synchronization.
