Programming Sentry Keys Using Scan Tool

Once key blank is cut, insert key into ignition switch. Turn ignition switch to ON position. Using scan tool, select THEFT ALARM, SKIM, MISCELLANEOUS, then PROGRAM IGNITION KEYS. Enter 4-digit Personal Identification Number (PIN) code. When programming is completed, Sentry Key Immobilizer Module (SKIM) will exit SECURED ACCESS mode and display status of key. PROGRAMMING SUCCESSFUL is displayed if SKIM sentry key programming is successful. If ignition key programming is unsuccessful, one of the following status messages may be displayed:

• LEARNED KEY IN IGNITION is displayed if key in the ignition has already been programmed into vehicle's SKIM.
• 8 KEYS ALREADY LEARNED, PROGRAMMING NOT DONE is displayed if 8 keys have already been programmed into SKIM. If a new key needs to be added due to a lost or defective key, the ERASE ALL KEYS function has to be performed. Original 7 keys plus additional new key may then be reprogrammed into SKIM.
• PROGRAMMING NOT ATTEMPTED is displayed after an ERASE ALL KEYS function is executed.
• PROGRAMING KEY FAILED is displayed if further diagnosis is required. To program additional keys, turn ignition switch to OFF position. Remove current programmed key and insert next new blank key. Turn ignition switch to RUN position. Re-enter SECURED ACCESS mode and repeat PROGRAM IGNITION KEYS procedure.
