Okay, so my problem is something to do with the locks in both doors.
The Drivers door can be locked from the outside with a key, but can't be locked from the inside .
The passenger door, unlocks from the inside, won't unlock from the outside with a key, and locks from the outside , and won't lock from the outside.

The car was a bit destroyed when we got it, my friends were turning it into a Derby car, and I fell in love with the beaut , and I couldn't let it happen. So, we got it, no rear view mirror, no speakers, no power steering resevior, and doors that are a puzzle! 😂
