the rear passenger side door wont unlock cant open door to take off door panel any ideas on how to get teh door panel off with the door closed?

I had same prob the actuator is probably stuck due to weak coil or gunk.
You can't get panel off without damaging it. What I did was have some one pull up firmly on the lock button while I locked and unlocked the central locking system over and over until the door unlocked. Sounds crazy but it worked
