If the A6 layout for the modules is the same as my A4, the lock pump is in the rear corner of the car, on the passenger side. In the trunk, pull up the carpeting behind the passenger rear wheel, and tucked down in there is the pump assembly. They're known to go bad and it's a pretty likely cause for your problem, provided your fuses are not blown.

SOURCE: audi a4 1995 central locking problem

Hi there.
I had exactly the same problem and there are 2 ways of solving it. The first is to pay your Audi Service Centre £350-£550 to replace it for you and the second way is to do it yourself which will cost well under £100 (depending on ebay). Firstly check the Central Locking Pump to make sure the hoses haven't come off. This is located in the very back right hand corner of the boot so you will need to remove the carpet and internal trim and you will see a block of sponge. Carefully lift the top off this and you will see the pump sat inside it.
Actually there is a great set of photos online to help you and I will add the link for you at the end. If the hoses are still connected and not leaking it is very likely that the internal compressor wheel has shattered (quite a common fault). I believe it is possible to open the pump and replace this wheel (in fact there is one for sale on a very popular auction site at the moment) but my own preference was to simply buy a whole new pump and replace that (£16.00 + £8 p+p off the same auction site).
The most important thing for you to remember is that when you look to buy a replacement pump you need to find one with the EXACT same serial number. The one in the diagram shown is
8LO 862 257 N but I have a sneaky feeling yours might end in an A.
Anyway, I hope this is of some help and dont worry about the connections as both air connectors and all 3 electrical ones are different sizes and will only fit in one place each.
Good luck.
Rik

SOURCE: remote central locking not working

As far as the central locking issue, it sounds like you need to replace your central locking pump. You can buy them online.
I have a 95 A6 and I am in the process of looking for a new central locking pump.
The part number may be 4A0 862 257 J, that is what it is for me.
There are directions online as to how to change this yourself once you get the part. If you buy from the dealership the part is $500.
Be thankful your child locks weren't engaged. We haven't been able to open our back doors since the pump went out.

SOURCE: 1999 Audi A3 1.8T Electric Windows and Central Locking Won't work

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

If it is a factory security system, usually locking/unlocking the doors with the key fob will reset it. On some vehicles, locking/unlocking the drivers door with the key will also reset it

How do you reset the alarm on a 1999 toyota camry if i dont have the remote locking mechanisim


Operation of the theft deterrent system is discussed in the 1999 Toyota Camry Owner's Manual beginningh on page 21. Unlocking the door with the key should disarm the alarm system. If it does not disarm when using the key, there are only two possibilities:

> You have an aftermarket alarm system installed in addition to the system tht was provided by the manufacturer and they are interfering with each other.

> OR

> Your vehicle needs service to correct the malfunction.

You might try unlocking the car from the passenger side or use the key to open the trunk first to see if this works. If it does, the switch inside the driver door is probably malfunctioning.

Central locking not locking all locks from drivers door, will unlock, but not lock. working fine on passenger door with key, locks all. switch to activate central locking on drivers door unlocks but doesnt...


You will need to replace the driver door switch. You can try to pick a switch up from the dealer or a local car wrecker (i.e. Pick-n-Pull). It will involve learning to take apart the door trim panel.

Toyota corolla verso 2007 . the central locking has stopped working


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.
