2003 Chrysler PT Cruiser GT, AutomaticSECTION Programming Ignition Keys Using Customer Learn Method
To program ignition keys using customer learn method, 2 programmed valid ignition keys must be available. If 2 programmed valid ignition keys are not available, scan tool method must be used.
- Insert first valid ignition key into ignition lock cylinder. Turn ignition on for at least 3 seconds, but no more than 15 seconds. Turn ignition off and remove key.
- Within 15 seconds, insert second valid ignition key and turn ignition on. After 10 seconds a chime will sound and theft alarm indicator will flash. Turn ignition off and remove key.
- Within 60 seconds, insert new ignition key and turn ignition on. After 10 seconds a chime will sound and theft alarm indicator will stop flashing then turn on for 3 seconds and turn off. New key is now programmed to SKIM.
- Repeat this procedure for additional new keys. A maximum of 8 keys can be programmed to vehicle. Customer learn method will automatically exit if SKIM senses a non-blank ignition key when a blank ignition key should be sensed, if 8 keys are already programmed or ignition switch is turned off for more than 50 seconds.
