    around once a month the remote locking on my b6 stops working, i have to open the door with the key then turn the ignition on and then it will work fine for weeks.
    since yesterday it has done it twice so i think its getting worse.
    i have 2 keys with a new battery in one of them but it makes no difference which key i use.
    anybody have a fix for this ?

    i have read something about a broken wire in the drivers door being to blame but not in any detail.
    mine used to be around once a month until a few days ago where it happened around 3 times in 2 days ! today it has worked perfectly everytime.

    if the key-fob is at fault, use the service fom the RAC which covers you for key-fob/imobilisers when you have the Reward or Premium account from Santander. no excess to pay and the fault is fixed mucho-cheapness.

    Ive had the same probs with my a4 , was driving me mad, locked the car put key in my pocket and everytime took key out it wouldnt work and had to use key and do a manual reset in ignition which would sort it, tried new battery, door looms fine, vag com wes reporting a key signal fault, took key fob apart again and cleaned everything up and bent the battery terminals a little more to ensure good contact and its been working 100% up till now :thumbsup:

    Ok I tackled the issue of my paggered key fob today... It was a little scary but I done it.

    The fob had been playing up at least 4-5 times a day.

    Basically bought a key case off eBay..

    Swapped all the internals out of my old key (battery, circuit board, key blade, battery and immobiliser) the circuit board was a ***** to get out but got it in the end and now I have a nice new shiny key :)

    Before...

    After...

    I wish I had gone for the b7 fob now but never mind I am happy with it looking all new and working fine so far.
