RE: AUTOMATIC DOOR LOCKS
1. Enter you vehicle & close all doors.
2. Fasten your seatbelt (Fastening your seatbelt will cancel any chiming that may confuse you during this programming procedure)
3. Place key in ignition.
4.Within 10 seconds cycle the key from OFF position to the ON position four times; ending in the ON position. (DO NOT START THE ENGINE)
5. Within 30 seconds, press the driver's lock switch in the LOCK position.
6. A single chime will be heard to indicate the feature has been disabled.
7. To reactivate this feature, repeat the above steps.
8. If a chime is not heard, program mode was canceled before the feature could be disabled. If necessary, repeat the above procedure.
This I know works on the 05's, not sure on the 03.
