My 89 535im, first the rear drivers side door lock started to fail, now it is stuck closed, I can not open it manually from inside, or via key.

Same with the trunk lock, it was sticking a bit and was becomming more difficult to open with the key, now it also is stuck closed, it will not open with the key or via drivers side or passengers side door locks.

I tried re-synching the locks from the passengers side door lock but no luck.

Any help is greatly appreciated.
