testy driver door key lock

[kvigeland]

I sometimes have to wait for my key to work on my '94 740il, turning the key full range around 10 times until all the doors unlock or all but the driver's side until I relock them all and then it will unlock them all. I just had the battery replaced due to low voltage although the passeger side won't unlock unless I perform the emergency entry technique and the rear drivers side interior door handle seems jammed and requires someone to open from the outside to let a passenger out. Should I spray WD-40 into the keylocks? The door system was properly reset by a BMW repair shop when they installed a new battery.
Any suggestions?
Thanks, Kurt Norman

if maybe a door bracket is broken, WD40 will not help you.
Hoe to remove the door panel and to fix a broken door bracket is shown on Johan's website.
