If you can t budge it at all it most likely is the lock.
Sliding door lock stuck closed. Passenger sliding door is stuck in lock position and won t open 2 years ago i replaced the lock actuator i pulled the inside trim off and with some force was able to unlock the door. Your sliding door operates on a track to open and close. Sometimes the set screw holds a cover plate on take the cover plate off and then you can get at the screws underneath the cover plate. In this video i attempt to open a patio door that has got stuck locked.
There should be a stop on the top or bottom of the door that the doors hits to prevent the door from sliding to far. If you can feel your door moving in a direction other than completely straight from left to right then your sticking door can be caused by a misalignment. Difficult to advise you on how to handle the lock without seeing it. Open close lock unlock then 2 days later it did it again.
The pictures look like to me that the door slid past the stops. Went back and forth with the assembly lock and unlock worked smoothly. In order for smooth and easy operation there is some slack that can potentially cause your door to come off the track. In addition to cleaning and lubricating sliding door tracks you want to lubricate the door lock.
Power door works fine now. The mechanics of the lock have broken leaving the top section of the door completely.
