Alarm System Transponder: Service and Repair

Three programmed Smart Key transponders are included with the Smart Key Immobilizer System (SKIS) when it is shipped from the factory The Smart Key Immobilizer Module (SKIM) can be programmed to recognize up to five additional transponders, for a total of eight Smart Keys. The following "Customer Learn" programming procedure for the programming of additional transponders requires access to at least two of the valid Smart Keys. If two valid Smart Keys are not available, Smart Key programming will require the use of a DRB scan tool and the proper Diagnostic Procedures.

Customer Learn
1. Obtain the additional Smart Key transponder blank(s) that are to be programmed for the vehicle. Cut the additional Smart Key transponder blanks to match the ignition lock cylinder mechanical key codes.
2. Insert one of the two valid Smart Key transponders into the ignition switch and turn the ignition switch to the ON position.
3. After the ignition switch has been in the ON position for about three seconds, but no more than fifteen seconds, cycle the ignition switch back to the OFF position. Replace the first valid Smart Key in the ignition lock cylinder with the second valid Smart Key and turn the ignition switch back to the ON position. Both operations must be performed within 15 seconds.
4. About ten seconds after the completion of Step 3, the VTSS indicator LED will start to flash and a single audible chime tone will sound to indicate that the system has entered the "Customer Learn" programming mode.
5. Within about fifty seconds of entering the "Customer Learn" programming mode, turn the ignition switch to the OFF position, replace the valid Smart Key with a blank Smart Key transponder, and turn the ignition switch back to the ON position.
6. About ten seconds after the completion of Step 5, a single audible chime tone will sound and the VTSS indicator LED will stop flashing and stay on solid for about three seconds to indicate that the blank Smart Key transponder has been successfully programmed. The SKIS will immediately return to normal system operation following exit from the "Customer Learn" programming mode.
7. Go back to Step 2 and repeat this process for each additional Smart Key transponder blank to be programmed.

If any of the above steps is not completed in the proper sequence, or within the allotted time, the SKIS will automatically exit the "Customer Learn" programming mode. The SKIS will also automatically exit the "Customer Learn" programming mode if it sees a non-blank Smart Key transponder when it should see a blank, if it has already programmed eight valid Smart Keys, or if the ignition switch is turned to the OFF position for more than about fifty seconds.
