I own a 2002 Dodge Grand Caravan Sport which has just developed 2 problems when physically using a key to unlock the driver's door. I have 3 keys programmed for this vehicle. When using one of the 3 to unlock the driver's door, the alarm sounds until I start the vehicle. Secondly, all the door locks don't unlock when turning the key to unlock twice, only in the driver's door. This unlock feature still works when performing the same action in the passenger door. Anyone know what's going on? Do I have to get this particular key reprogrammed? What about the unlocking all locks function? Any help would be greatly appreciated. Thank you.
