Thanks for the reply.
When I use the key to unlock, everything is fine. One turn unlocks drivers door, two turns unlocks everything else. I can NOT unlock with the key fob remote. That is when the alarm goes off. I only have one key fob.
This thing worked fine up until just before we left on vacation mid-September, then all of a sudden the alarm started going off when we unlock with the remote.(Alarm sounds and the doors lock).
No add ons or modifications since I bought the vehicle in Jan 03.
Do you know how to reprogram the key fob?
