Programming pass-key

Hi and thanks for using 2CarPros.com.

There are two ways to do it. One requires a scanner and the other does not. However, it takes thirty minutes to do without the scanner. Here are the directions without the scanner:

___________________________-

30-Minute Relearn Procedure
Use this procedure after replacing the following components:
- The passkey III (PK3) keys
- The theft deterrent control module
- The PCM, see important above

IMPORTANT: This procedure is not available on vehicles equipped with option code (Z49 or BAE).
If replacing a theft deterrent control module with an GM SPO Replacement Part, perform the procedure to setup a new theft deterrent control module prior to the 30-minute relearn procedure.

1. With a master passkey III key (Black), turn ON the ignition, with the engine OFF.
2. Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
3. Turn OFF the ignition, and wait 5 seconds.
4. 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.

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

Let me know if this helps or if you have other questions.

Take care,

I have done that over twenty times and the security light does not turn off. Car turns over for a second but will not start.

And my key does not say passkey 3 it is a B97-PT.

It is not working.
