My citroen c3 . 2003 the door lock won't work and my battery has died how do I gt into the car to open the bonnet or can I go underneath the car to release bonnet catch

You should be able to open the door manually with the key and you may have to turn it twice. Also try unlocking it whilst at the same time pulling on the door handle to the opening position or pulling the door handle to the opening position and then working the lock to open it manually. One way or the other it is designed to be opened manually with the key when there is a power failure with the power operated central locking not then operable.

Central locking not operaiting

Was the car battery disconnected before this central locking problem.Also is the central locking system operated by remote.If yes,then is the remote battery new or old.If the battery in remote is old then try with new battery.Also if the central locking is controlled by a push button in the car then it can be the problem with push button switch .The switch on driver side is got short.It has to be checked with meter to confirm the fault.Apply a direct 12 volt external battery to the switch and check if the central locking is getting done.Also confirm if you can lock the doors manually by using a car key.If you are not able to lock the door with key manually then its faulty door latch.But if the door lock and unlock manually with out any problem then this problem is related to central locking switch or the remote.

Door locks not operation correctly


there is a motor placed inside the doors for the operation of the central lockin system. when you open the door by key this motos is activated and all door locks are released. your problem may because of this motor is failed.

cause of the failure
1.the wire going to the motor may be chopped off.
2.the junction box connecting the wires may be damaged.
3.fuse may be blown out.
4.motor itsef damaged.

so please check weather power is coming to the motor using multi meter. if the power is not coming to it then the problem is with the wires. if the power is coming to it then problem is with the motor.

please vote me if my answer was useful to you.

Automatic door locks will not lock rear doors, they open fine when manually locked but will not lock with switch key fob or when put in gear.

You mean that the central locking system will not lock the rear doors but you can do so manually.

Get inside the vehicle and close all doors.

On each rear door, lock and unlock the mechanism manually a couple of times. In other words do not use the key pad.

Then leave both rear doors in the locked position (manual locking) and operate the lock button on you key pad to operate the central locking system. Wait a few seconds then hit unlock on your key pad and a few seconds later hit lock on your key pad.

If the system fails to lock your rear doors you will need to get the vehicle to an auto electrician to check out the issue and rectify it for you. There are a number of possible causes which cannot be identified without physically checking the system. So you will need to have this rectified by a professional.

Central locking

If the remote's battery has never been replaced, it's probably time now. The type of battery employed in these has a 'shelf-life' of around 5 years so if yours hasn't been replaced, you are overdue.
As far as the failure of individual door locks to operate, the mechanism may have corrosion that is impeding their travel. Check the owner's manual, it may give information about freeing sticky locks.
If you don't have an owner's manual, I can recommend the Haynes service manuals. They cost ~$20-$30 US and can be had in most auto parts stores.
