ok so there is a pump that controls the locks. there is a way we can try and reset it by pulling the fuse for it., ill send over a link with the location of the fuse we need to pull and check and reinsert, if the pump works after reinserting then we may be good for a bit. if not we need to access the pump in the trunk.

Hello, did you have a chance to check the fuse and see if the locks work after removing and re inserting the fuse?
