Service Procedure
The following service procedure provides instructions for reprogramming the body control module (BCM) to turn off the key lock/unlock feature. The owner's manual will also need to be updated.Notice:
On vehicles equipped with the remote vehicle start system, the system will be disabled when performing this procedure. To re-enable the feature, an SPS reprogram via "pass-thru" will need to be performed. The system CANNOT be turned back on using Tech 2 alone. Failure to perform the SPS reprogramming using "pass-thru" as instructed in this procedure will result in the remote vehicle start system being inoperable.

In order to perform the following procedure, the diagnostic interface module (CANdi) must be connected between the Tech 2 and the vehicle. Failure to use the CANdi module will result in failure of the Tech 2 to communicate with the necessary module on the vehicle.
