Disconnected battery to reset computer when central locking failed after a blown fuse and as a result bluetooth is now not connecting, it is a 2005 320i and the little telephone icon is not appearing above the telephone button.
Re: Disconnected battery to reset computer when central...
I recently replaced the battery in my 2006 X5 diesel, now the central locking is not working, I am in a remote location and not able to attend a BMW dealer, is there anyway I can resent the central locking. Cheers allen

There is only one fuse that mentions 'Locking', but also refers to the General Electrical Module (GEM). If you change the fob battery, you need to reprogram it to the vehicle. Or you could open any Transit around you. Lots of help below including resetting..
Follow the wiring after the fuse. look for burnt wires. pinched wires, failed locking solenoid wire to earth some where. Remember that the wire you are following will be live up to the point it earths out and over loads the fuse. Check all lock solenoids or the point where the wires go from the body to the door.
I would suspect the fuel flap actuator has failed. Open the trunk. In the right rear corner is the access cover. Open it and you'll see some insulation matting near the top. Behind it is a fuse/relay carrier, I believe either fuse 55 or 56 is blown. If so the fuel flap actuator needs replaced. The fuse also controls the central locking system.
Check all the fuses if the fuse is blown that gives power to the computer while the key is off the computer can loose it memory. On some cars for some unknown reason when the car is off the computer losses the readiness test results. The only thing you can do is drive the car around for at least ½ hour then take it to the inspection station and have the test run but DO NOT shut the engine off. A dead or disconnected battery will also clear the readiness results. The bummer is there is no bulletproof fix.
I will suggest to check the wire harness from truck. try to take off the rubber grommet close to trunk hinges. then inspect if there is dammage wire but if you can;t find any fault with it, i suggest to disconnect one by one the connector from each door and and obseve the fuse and if the fault still existing check the central locking module for possible water ingress resulting to blown your fuse
fuse 56 and 57 control central locking,the issue is caused by surges typically in the front door lock actuators, normally at a dealer they would replace fuse 56 and 57 with a 20a mini fuse and if still occuring repl the door lock(s) that dont work or typically both front, first replace fuse 56 and 57 with 20a fuses as were too small from factory and than operate ten to 15 times, if it doesnt work at first dont panic,let the car go to sleep which takes about 16 min and than try again this problem has nothing to do with the key fob or the lock unlock button inside,also the fuses are located behind the glove box just rere the access panel and they are found at lower left section
hello, there is a central locking fuse located in the fuse holder above the battery in the trunk. when you access the trim, look on the fuse description on the back side of the trim cover. I believe it may be either fuse #54 or #56. if the fuse is blown, you probably have a failed fuel flap actuator.
