Programming Replacement Keys, Ignition Cylinder, or Powertrain Control Module. Buick GL7 (Export) 2000

For 1990-2009 cars

Important:

• | If replacing a theft deterrent controller module with an 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 controller module is replaced.

• | If 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 VTD 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.

### 10 Minute Re-Learn Procedure (Export and Domestic vehicles)
