Alarm Module: Testing and Inspection

Each ignition key transponder also has a unique ID code that is assigned at the time the key is manufactured. When a key is programmed into the SKIM, the transponder ID code is learned by the module and the transponder acquires the unique Secret Key ID code from the SKIM. To program ignition keys into the SKIM, follow the programming steps outlined in the diagnostic scan tool for "Program Ignition Keys or Key FOBs" under the "SKIM" menu item.

NOTE: A maximum of eight keys can be learned to each SKIM. Once a key is learned to a SKIM, that key has acquired the Secret Key for that SKIM and cannot be transferred to any other SKIM or vehicle.

If ignition key programming is unsuccessful, the scan tool will display one of the following error messages:
- Programming Not Attempted - The scan tool attempts to read the programmed key status and there are no keys programmed into SKIM memory.
- Programming Key Failed (Possible Used Key From Wrong Vehicle) - SKIM is unable to program an ignition key transponder due to one of the following:
- The ignition key transponder is faulty.
- The ignition key transponder is or has been already programmed to another vehicle.

- 8 Keys Already Learned, Programming Not Done - The SKIM transponder ID memory is full.
- Learned Key In Ignition - The ID for the ignition key transponder currently in the ignition lock cylinder is already programmed into SKIM memory.
