My Buick Park Avenue Car Door Won't Openby Diana Braun
The Buick Park Avenue is a full-sized sedan that was made from 1990 to 2005. The car features a central automatic locking system that controls the locking and unlocking of all doors and the trunk. The ignition key or key remote is used to unlock and open the doors. A door that doesn't open may be the result of a key remote with a dead battery. A sticky door lock may also cause a door to fail to open.
Spray lubricant into the door keyhole. Insert the key and wiggle to open.
Check the battery on the key remote. Insert a flathead screw driver into the remote to pry open the two halves and access the battery compartment. Remove the battery and replace with a new one. The battery model number is stamped on the battery.
Resynchronize your car remote. Stand 3 to 10 feet from your vehicle. Aim the car remote at your vehicle and press and hold the "Lock" and "Unlock" buttons on the remote at the same time for about 8 to 10 seconds.
Bring your car to a local Buick dealership. The lock mechanism may be jammed or broken. A mechanic can properly diagnose and repair the exact problem.
