I don't really know but the first things I would try are: push door lock/unlock button and try to unlock it with the key.
"Slide a big size screw driver to act as the rod on which the door supposed to hook in the normal operation, and try to pull the handle while pulling the door out and pulling the screw driver toward the car. Hope that will help."
Worked for my 90 thunderbird, thanks.
Isn't that annoying: it's happened to me on two different doors. It has nothing to do with the lock mechanism, but instead is a little locking hook inside the door where it meets up with the locking post. It will be in a shut position. Depending on the door, you may have to removed a little plastic cover just above it for better visability. As I recall, you need a strong flat head screw driver to snap the ring open - not forecefully, but strong enough to flip it open. As strong as that locking ring may seem, it comes right open when addressed from the proper direction.
Happened to us twice. I just lifted the outside door handle and flipped the catch with my other hand.
Just want to thank the people who submitted responses to this person's question... it worked for me -many THANK YOUs to you!!!!
man thanks alot i went to family dollar trying to buy star head alum wrench tools and got all the screw off after stripping the set and it didnt work i didnt know it would be that easy i was t'eed off but seeing this really took the pressure off of me 30 seconds later |P|O|W|!| it popped open
Rotate the latch while lifting the door handle worked for '96 Burb with power door locks.
This happens when the doors are put on child lock, or locked out from the driver door electric locks. I do not know why it happens but happens to us all the time. Be careful not to gauge out the rubber casings around the part that is stopping door from closing, seems to make it happen more often once gone. we quit using the child locks!
THANKS
I just wanted to say THANKS to the person who first answered this question!!! You da bomb!!
