Central locking not working and stereo no power i dont have manual to check where fuse is ive tried going through them all but still no nearer

Did you happen to check main fuses under the hood

Black is ground, yellow is battery constant power for memory (clock, station memory, etc...) you burnt the fuse for that constant battery power. Just check for burnt fuses

it could be a problem with the central locking unit. you would need to have the system red on a obd read that does this part of the vehicle, you could try to reset the system key in ignition turn to number 2, press fob doors should lock and unlock with the button pressed. as for the side door this is controlled by the front door on that side this door has to be locked and the pin moved in the lock to send the power to lock the side door. with the central locking not working on the system and you manually locking it it may not be going all the way to lock both doors. or the central locking is not working at all. the fuse for central locking is in the main fuse box.

double posted,
Check all fuses... in cab and eng. bay.
try again, again, say what dont work?
key fobs (all) dead??
or keys actual, or what,
what works and what dont. ???????????

central locking is complex. lots of switches fob and doors.
try saying what dont work exactly , instead of just central.......

see that the button on your fob is not stuck.

sounds like there's an issue with your fuses, you'll probably need to buy a full fuse set for your matiz. if not check that all the cables are in tact and that nothing is disconnected.

alot of new cars have the imobilizer in the stereo ,for you sake i hope he didnt chop off the old stereo plug ,he needs to refit the old stereo ,

The door lock solenoid for the passenger side is possibly defective, and that is what caused the fuse to blow in the first place. If you apply voltage to the solenoid and it works, then the driver transistor or wiring would be the next place to check. Hope this helps.

Hi I wonder if you can advise me ,my central locking and alarm is very unreliable it keeps making a beep before the ignition goes on and clicking,it sometimes sets the alarm off,Ive had the AA round and theyve told me the car battery is dead,which I appreciate,but think the key hub central locking or alarm is running the battery low does the hand held button need a new battery,or can I take the fuse out for the central locking,dont want to pay 66 quid for a new battery if I can pay 2 quid for a new battery for the central locking button,or demobilize it

I've been dealing with similar problems (windows and sunroof dead, power locks iffy, dome light doesn't work, random chiming) and best I can figure is:

a) get rid of the leak and any standing water
b) depending on the year of your car check the relays and/or central locking module

I spent a lot of time checking the ECU and door interior parts and those were both dead ends. I also thought the standing water on the floor might be shorting actual wiring, but now I've eliminated that as well. Although my alarm hasn't been going off, the "door chime" has and the instrument cluster sometimes shows 3 or 4 doors open while driving. VAG-COM showed some alarm trip type faults as well. Central locking is my next move when I've got some time.
