Central Locking not working remote makes indicators flash but doors wont lock or unlock. Also the switch in side on door panel

My 2007 astra central locking went crazy doors not locking some wouldn't unlock ,tail gate not latching, hole locking system not working, no indicator flashes when pushing remote, wires from body to door inside rubber boot were broken , very hard brittle plastic coating on wires where they need to bend n flex

It's only an educated guess. If all other locks switches are working it' either the switch panel itself or an electrical short. Switches are popular, get it checked first

Could be a few things. Do they unlock from the central locking switch in the car? Close all the doors first then push the button. Do they unlock with the key remote? Does the drivers door unlock when the key is inserted? If they don't work at all check the fuse in the trunk area on the right side. There is a panel that pulls down and reveals 5-10 fuses.

Try the following:

Toyota Corolla Verso - Central locking has just stopped responding


So you don't waste your time, here are some assumptions: -

1. When I press the key fob there is no sound of doors trying to lock/unlock and I know the key fob is fine.


Solution:


In this situation reset the alarm/locking system

Below is the procedure I followed to get the central locking working again: -

Open the passenger door, and look at the side of the dash board. There should be a triangular panel. Pull the panel off to reveal a small set of fuses(see the back of the panel for the fuse map). To power down the central locking you need to remove the Dome Light fuse, this is located top left. Second one down 7.5 amps. (if in doubt remove the top two 7.5 amp fuses I did)

When you remove the fuse(s) you will notice the interior light go out indicating you have powered down the system.

Now leave them out for at least 30 mins so any capacitors can discharge properly. (Be aware while the fuse is removed all central locking is disabled, so the other doors are open. I left the fuse(s) out over night with all the doors open but I don't recommend it, 30 mins should be fine)

After 30 mins replace the fuse(s) close all doors, and then try your key fob, hopefully you should here that satisfying locking sound.


2. When I press the key fob I hear the locking system trying to engage.

This could be a faulty door switch on any door including the boot, or there could be a dent in the inner door panel of any of the doors, usualy the rear doors due to the seat belt not retracting properly.

Solution:

Check all door switches for damage, and check inner panel for dents, just a small dent where the switch connects can be enough to not engage the switch. This will stop the central locking.

Use some kitchen roll wrapped in tape (as a makeshift pad) and tape to the inner door as a temp measure to engage the door switch. At least you can then lock the car.

Programming
When
Key batteries completely discharged. Key batteries not replaced within 60 seconds. Key added or replaced. DO NOT press remote control buttons during battery replacement.
How
Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button Fig. 1 [1]. Press lock button Fig. 1 [2] briefly 3 times within 10 seconds keeping unlock button [1] depressed. Release unlock button Fig. 1 [1]. Some models: LED Fig. 1 [3] flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Some models: Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously

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.

To change batteries remove panel back of key then screws on plastic bar
Batteries are available from your local motor factor shop
You might not need new batteries try re programing as described above

If all the doors do not lock or unlock when using the passenger side switch, then the switch itself is probably bad.   If the passenger side switch locks or unlocks all the other doors except for its own, then the power lock solenoid inside the door is bad or jammed.  If it is jammed, try locking and unlocking the door manually while activating the switch to work its way free.
