Alarm System Transponder: Service and Repair
Transponder Programming
STANDARD PROCEDURE - TRANSPONDER PROGRAMMING
Two programmed Sentry Key transponders are included with the Sentry Key Immobilizer System (SKIS) when it is shipped from the factory. The
Sentry Key Immobilizer Module (SKIM) can be programmed to recognize up to six additional transponders, for a total of eight Sentry Keys. The
following "Customer Learn" programming procedure for the programming of additional transponders requires access to at least two of the valid Sentry
Keys. If two valid Sentry Keys are not available, Sentry Key programming will require the use of a DRB III(R) scan tool.
Customer Learn Programming
1. Obtain the additional Sentry Key transponder blank(s) that are to be programmed for the vehicle. Cut the additional Sentry Key transponder blanks
to match the ignition lock cylinder mechanical key codes.
2. Insert one of the two valid Sentry 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 Sentry Key in the ignition lock cylinder with the second valid Sentry 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
Sentry Key with a blank Sentry 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 and then turn OFF to indicate that the blank Sentry 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 Sentry 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 Sentry Key
transponder when it should see a blank, if it has already programmed eight valid Sentry Keys, or if the ignition switch is turned to the OFF position
for more than about fifty seconds.
NOTE: While in Customer Learn mode (LED flashing), the engine will not START and RUN.
