The oil pressure needs to be checked with a mechanical gauge just to make sure we are dealing with a gauge issue. I suspect it is since it is running well but we need to confirm that. Then we can test wiring and finally replace the sender or gauge depending on what you find in the attached tests.

As for the door locks make sure you check fuse 9 and 13. If these are ok, more than likely the driver door switch has failed. If this is shorted, it can actually cause all of them to not work.
