You may not wish to hear this but, I would suspect in your case that the key lock cylindedrs are getting all full of bad grease. I would take them out and spray them good with WD-40. I just had a similar issue with my 1990 325ic and I ended up repalcing the drivers door lock motor as well as the central lock controller. If cleaning up the lock cylinders does not work, try unhooking the door lock motor and with door shut using lock button to lock and unlock the door. If this works smoothly then it is probably bad lock cylinders and you can buy a rekey cylinder at the dealer, rekey and then replace the old with the new.
