The Customer Learn programming method procedures are as follows:
1. Cut the blank key(s) to match your current valid keys.
2. Insert one of the two valid Sentry Keys into the ignition switch and turn the ignition switch to the ON position. After the ignition switch has been in the ON position for longer than three seconds , but no more than fifteen seconds , cycle the ignition switch back to the OFF position.
3. Remove the first key and insert the second valid key and turn the ignition switch back to the ON position. After about ten seconds the SKIS indicator in the instrument cluster will start to flash and a single audible chime tone will sound to indicate that the system has entered the Customer Learn programming mode.
(The second valid Sentry Key must be inserted in the lock cylinder within fifteen seconds of removing the first valid key)
4. Within sixty 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. After about ten seconds, a single audible chime tone will sound and the SKIS indicator will stop flashing, stay on solid for three seconds and then turn OFF to indicate that the blank Sentry Key has been successfully programmed.
The SKIS will immediately exit the Customer Learn programming mode and the vehicle may now be started using the newly programmed valid Sentry Key
