I have a problem with my 2003 BMW X5, the central locking system, interior light, remote key entry, and alarm stop working, The key does open the back door but nothing else. I tried to reset the key fob, but that did not work. I got it put on the computer and it is saying there is a wire broke. Can you help or point me in the right direction of what cable it might be?

The alarm and the central locking are all part of the remote keying system. You will not fix it with changing fuses because it is likely the ECU needs to be be reset. Unfortunately, it will require a visit to an authorised workshop to do this
on the BMW there is an electronic control module that controls all of these functions, sounds like you have a problem with it. Check your fuses, if non are blow there are dealers on e bay that can repair it for around the £70 mark. I have a similar problem with my 3 series
You need to check for any lighting left on overnight if not try to fully recharge your battery and perform a load test on it to see if it will hold the charge if so possible drainage off of interior lighting switches or alarm possible
try locking and unlocking the car with the key 3 times slowly ,other than that i have no idea ?? another trick is to disconnect battery and join the cables together for a few minutes to discharge any capacitors that may be holding a charge in the computer..Only other thing i can think of is the main dealers who have the right connectors and software to re set it all .sorry i havent been of any help
with any BMW they have their problems, one is the central locking/immobilizer, the central locking is linked into the immobilizer and vice versa, the immobilizer takes it signal to disarm from the central locking and the ignition key ring. (chip in the key) if one of these starts to play up it has loads of consequences this being one of them. they all need to work together for the system to work properly. you would need to read the alarm and immobiliser codes using an ob2 tool that can detect them, and find the fault some problems it can be the drivers door sensor in the lock this is the main door as its drivers side and it controls all other doors on the central locking. if the switch is worn in any of it movements the system will not know the door has been opened, this does not work on the interior light as that is a switch in the door frame. the door lock is lock unlock and deadlock with key with remote fob its also arm disarm alarm and immobiliser. i have seen in some models there is a sensor auto lock so when you walk away with the key the doors lock automatically all lease parts work together. any one having a problem can cause no signal to be sent to the others in the system to start engine .
