Door Locks

[BMRGRL]

Hey guys...New to this site, but I have read all threads involving door lock problems. I just bought a 1991 735il, and I'm having problems with the locks. (If you're reading this Dave---HI!) The driver's side door doesn't lock OR unlock with the key. I am able to lock ALL doors using the passenger's side, but I cannot UNlock the passenger's side at all. (except from the inside, obviously). I tried synchronizing the locks many many times, to no avail. The only way I can unlock the pass. side is by holding the handle up while turning they key. So, basically....if I go somewhere and I want to lock the car, I have to lock the drivers side manually, by pushing the button down, then go around to the passenger's side to lock the remaining 3 doors. Then, when I come back to the car to UNLOCK it, I have to use the passenger side which unlocks all doors except, oddly enough, the passenger side, itself.
I hope this makes sense. Since I JUST bought the car yesterday, I really don't want to have to spend a bunch of money to have the locks fixed, so I'm asking for your help.

wish i had low budget cure but there isn't one. several things go wrong with E32 front doors. sounds as though you have several problems. L/F door you'll need a 'lock cylinder repair kit' AND, most likely a door handle...........the cams inside the lock cyl. wear or break AND the bracket for the lock actuator breaks [which is part of the handle]. unfortunately theres no repair except replacement.

R/F door sounds like just the lock cylinder is bad. this MAY get to the point where the 'override mechanical release' will no longer work! ! THIS was designed into the door system so you could unlock the door if the battery went dead. when you normally unlock the car with the key, there's no actual mechanical connection to the door latch, just to the actuator and microswitches on the lock cylinder.

i think fixing you pass. door first would be the most cost effective way but BE SURE who ever does it knows what there doing! I've even seen dealership tech's ruin new lock cylinder kits by putting them together wrong.....best fortune to you.............jb.
