All locks lock simultaneously when i sit in car and push down drivers side door button so that seems to be ok. I suppose all the locks have failed mechanically one by one? Was using some lubricant for a time which helped open and lock doors however that doesnt work now. The key doesnt even turn any longer in the door lock. Is this fixable ie can i replace inner workings of the lock without needing new key?
p.s. am hoping to buy replacement fob for my after market spyball alarm system.. may or may not still be working.. poor auld bimmer really needs some tlc at this stage!!
Any help much appreciated. thanks
When you say "NOT WORK" on doorlocks, 2 things come into play. the mechanical part & the electrical part.
1) the mechanical part - the key the lock cylinder, and the tumblers. some WD40 sparingly sprayed into the keyhole should free these up. In cold weather though it may be harder to turn sometimes, but u will get there provided there is no mechanical damage. Not likely all 3 locks fail in succession though.
TIP: if the key you are using is not originally from BMW, that might be the reason you are having problems. Duplication of a copy... of a copy... of a copy. wil result in a wrongly cut key.
2) the electrical part - the wires, the module(with or without anti-theft options), and the actuators. I assume that is not the problem here.
TIP2: i recently posted a caveat regarding aftermarket fobs and alarms. Don't chance it. These aftermarket fobs are not compatible with BMW electrics and I have seen too many cases of the alarm circuit overriding the bimmer electrics resulting in no-start conditions. so Watch Out.
