Hi matt:


Try this:

Use this procedure after replacing the following components:

   •  The PASS-Key III (PK3) keys

   •  The BCM

   •  The PCM

Important: This procedure is not available on vehicles equipped with option code (Z49).

If replacing a BCM with an GM SPO replacement part, perform the procedure to setup a new BCM prior to the 30-Minute Relearn Procedure.


With a master PASS-Key III key, rotate the ignition to the CRANK position.
Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

With a master PASS-Key III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
With a scan tool, clear any DTCs.


This is right out of our service manual. If it doesn't work you will have to goto the dealer. When they say mater key that is your new key the first one you program is the "master" after that one is done then to program a second key just start the car with the master one turn tyhe car off and within 10 seconds start the car with the second key.

Good luck :)

happy new year too
