Theft Deterrent - Replacement Keys - IGN CYL, or PCM

Programming Replacement Keys, Ign Cyl, Or PCM

IMPORTANT:
^ When replacing the Theft Deterrent Module with a GM Service Parts Operation (SPO) Replacement Part, the module will learn keys immediately. The existing PCM however, must learn the new fuel continue password when the theft deterrent module is replaced.
^ When replacing a PCM with a GM Service Parts Operation (SPO) Replacement Part, after programming, these modules will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicles fuel continue password and will require a Learn procedure after programming to learn the current vehicle's password.
^ When performing the 10 Minute or the 30 Minute Re-Learn Procedures, all previously learned keys will be erased from the Theft Deterrent Module's memory.
^ Additional keys may be learned immediately after the 10 Minute or 30 Minute Re-Learn Procedure by inserting the additional key to be learned and turning the ignition to RUN within 10 Seconds of removing the previously learned key.
^ When performing the 10 Minute or the 30 Minute Re-Learn Procedures, be sure to use only a master Theft Deterrent Key (Black) during the procedure. If a Valet Key (Gray) is learned first, the Theft Deterrent Module will not allow additional keys to be learned.

10 Minute Re-Learn Procedure
Use this procedure after replacing:
^ Keys/Lock Cylinders
^ Theft Deterrent Module
^ PCM (if necessary, see Important above)

TOOLS REQUIRED
^ Tech 2
^ Techline Terminal with current Service Programing System (SPS) software

1. Connect the Tech 2 Diagnostic tool.
2. Select Request Information under Service Programing.
3. Disconnect the Tech 2 from the vehicle and connect it to a Techline Terminal.
4. On the Techline Terminal, select Theft Module Re-Learn under Service Programming.
5. Disconnect the Tech 2 from the Techline Terminal and re-connect it to the vehicle.
6. Turn ON the ignition, with the engine OFF, using a Master Theft Deterrent Key (Black).
7. Select VTD Re-Learn under Service Programming.
8. At this point the Tech 2 must remain connected for the duration of the 10 minute Re-Learn period.
9. Observe the Security telltale, after approximately 10 minutes the telltale will turn off. (The vehicle is now ready to re-learn the key information and/or passwords on the next ignition switch transition from OFF to CRANK)
10. Turn OFF the ignition and wait 5 seconds.
11. Start the vehicle (the scan tool has now learned the key and password information).
12. With the scan tool, clear any DTCs

30 Minute Re-Learn Procedure
Use this procedure after replacing:
^ Keys/Lock Cylinders
^ Theft Deterrent Module
^ PCM (if necessary, see important above)

1. Turn ON the ignition, with the engine OFF using a Master Theft Deterrent Key (Black).
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 through 3 two more times for a total of 3 cycles or 30 minutes.

IMPORTANT: The vehicle learns the the key 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. Start the vehicle (the vehicle has now learned the key and password information).
6. With a scan tool, clear any DTCs.

Quick Learn Procedure - Keys Only

IMPORTANT:
^ Additional Master Theft Deterrent Keys (Black) or Valet Keys (Gray) may be added (up to 10 keys) using this procedure when there is an available learned Master Theft Deterrent Key (Black).
^ This procedure adds keys only, it does not erase previously learned keys.
^ The keys to be learned must duplicate the mechanical cut of the current key.
^ If more than one Valet Key (Gray) is to be learned, each must be immediately preceded by a learned Master Theft Deterrent Key (Black).
1. With a previously learned Master Theft Deterrent Key (Black), turn ON the ignition, with the engine OFF.
2. Turn OFF the ignition and remove the key.
3. Within 10 Seconds insert the key to be learned (either Black or Gray) and turn ON the ignition, with the engine OFF. The vehicle has now learned the new key(s).
