Why accounts for BMW intermittent door lock failure?

Answer by  JB19 (167)

Your door lock actuators may need to be replaced. As they age they lose strength which causes intermittent failures to lock. This will require purchasing new actuators, opening the doors and replacing the actuators. This can easily be done by someone of moderate mechanical skill however be aware that the old actuators may be riveted in place.

When this occurs you either need to replace the fuse or take it to the dealer and have the solenoids and actuators replaced. You can use your valet key to access your vehicle if the key fob stops working as well. Worse case scenario you may have a short circuit that needs tracked down by the dealer.
