Key Programming Using Diagnostic Equipment

Key Programming Using Diagnostic Equipment

General Procedure

NOTE: To enter PATS (Passive Anti-Theft System) security access if no programmed IA (Intelligent Access) keys are available, start a vehicle session using a tear tag or PCM (Powertrain Control Module) part number. PATS (Passive Anti-Theft System) security access can still be granted even with the ignition off.

1. Insert the unprogrammed IA (Intelligent Access) key into the backup slot.

2. From the scan tool, enter TOOLBOX. Select Body>Security>PATS Functions and follow the IDS (Integrated Diagnostic System) on-screen instructions to enter PATS (Passive Anti-Theft System) security access.

3. From the scan tool menu select "Program additional ignition key" and follow the IDS (Integrated Diagnostic System) on-screen instructions.

4. NOTE: The engine will not start until there are at least 2 keys programmed.
The engine should now start with the IDS (Integrated Diagnostic System) key.

5. If it is desired to program an additional key (only up to 4 keys total can be programmed), insert the additional key into the backup slot and repeat Step 3 for the additional key that needs to be programmed.
