THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15 At the time of purchase, the original owner is provided with a four digit PIN number. This number is required for dealer replacement of keys. Duplication of keys may be performed at an authorized dealer or by using the Customer Key Programming procedure. This procedure consists of programming a blank key to the vehicle electronics. A blank key is one which has never been programmed. NOTE: When having the Sentry Key System serviced, bring all vehicle keys to the dealer. Customer Key Programming You can program new keys to the system if you have two valid keys by doing the following: 1. Cut the additional Sentry Key Transponder blank(s) to match the ignition switch lock cylinder key code. 2. Insert the first valid key into the ignition switch and turn the ignition switch ON for at least 3 seconds but no longer than 15 seconds. Turn the ignition switch OFF and remove the first key. 3. Insert the second valid key and turn the ignition switch ON within 15 seconds. After ten seconds, a chime will sound and the SKIM indicator light will begin to flash. Turn the ignition switch OFF and remove the second key. 4. Insert a blank Sentry Key into the ignition switch and turn the ignition switch ON within 60 seconds. After 10 seconds, a single chime will sound. The SKIM indicator light will stop flashing, turn on for 3 seconds; then turn off. The new Sentry Key has been programmed. Repeat this process to program up to a total of 8 keys. 2
