Title: Key fob and central locking problem
Post by: Jayz on 09 March 2011, 08:32
I have a 1999 mk4 golf 1.8t AGU, Central locking: when I brought the car the guy told me the central locking needed fixing meaning when i use the key and open the drivers door only the drivers door opens, then i have to put the key in the ignition turn it one the press the unlock button on side on the drivers door where the window switches are to unlock the rest of the doors. But when I get out the car and lock the drivers door all the doors locks fine any ideas?

Key Fob: was not working from the start, I've put a new battery and still nothing, my guess is that the key has lost its code? Anyone know how to sort this? I've only got one key at the mo, I've brought a blank key from ebay but need to get it cut.

cheers in advance

Aparently (never tried it but been sugested on here quite a few times) you can code the key pretty easily, problem is you need a second key.

I believe you need vagcom to recode it.

I'm not entirely sure. Been a while since anyones posted about it but I'm sure it was something to do with putting one key in the egnision, having one key in the door and pressing lock or something like that, again not sure if it works. Personally if I was you and you do know someone with vagcom ide ask them if they know how to code them with vagcom, or have a look in the vagcom section on here and ask if there's anyone neer you with vagcom and if they know if/how you can code keys.

will be easy to code them with vagcom if you know someone

i think this is the method where put new key in the ignition and press a sequence on the old key fob there is a guide some where

Found it, this is copied from here (http://uk-mkivs.net/forums/p/293896/1946727.aspx)

Remote Control Programming (1997 ON)

Procedure
1. Switch Ignition ON and leave the key in the ignition.

2. Mechanically lock the vehicle using the Drivers door using a second
key.

3. Using the remote control press the Unlock button once, and the horn
will sound once.

4. Wait 6 seconds and press the unlock button once to activate the coding
procedure. The remote control will now be programmed.

NOTE : When performing programming on additional remotes the procedure
is the same, except you press the unlock button 2, 3 or 4 times for the
different remote.

For example : If programming 2 remotes press the unlock button twice with
a 1 second interval between each press, repeat for 3 and 4 remotes.

5. Switch Ignition OFF.

6. Remove key from ignition and check for operation.

7. The coding procedure can be repeated up to 4 times for additional remotes.

8. The ignition must be switched OFF between programming each remote
control.

Could the solonoids be at fault with regards to the doors not unlocking?

Are there different solonoids for locking and unlocking?

Its all one module and each door has its own module

With regards to only unlocking the drivers door, it does that by default.  Two quick successive presses unlocks the rest of the car

+1, completely forgot about that. I use my key rather than a fob and have to unlike twice to unlock the whole car.

But my cousin has a golf aswell and all his doors open when he puts the key in and unlocks it once

If you use the key then yes it opens the entire car.  Using the fob remotely its designed to open just the drivers door unless its been reprogrammed to open the entire car
