Hi Guys

Had a friend with a 2nd hand car he bought which we flashed a stock file onto the car, he wasnt sure where the tune that was on the car came from and it was surging and really running badly. After the flash the key fob stopped locking/unlocking the doors, tried all the tricks key in ignition with unlock button pressed and a few others. When trying to access to the 2 vcds modules to check the key stuff we also get an error there. I was under the understanding that the key/cluster stuff had no reference to the flash so I am a little confused why this happened after the flash?

laugh, I thought it was a coincidence but it happened as I did the flash now try explain that to your mate... well it was working 10mins ago and as I flashed your car the key stopped working... anyway thought I was right and the key/cluster stuff is not linked to the flash at all.

Have you tried Procedure for older Golf IV and Procedure for newer Golf IV??

the solution was to put one key in and turn ignition on.
then go outside close the door and lock the door.
then use the open button of the new remote to open the car.
press the open button a 2nd time.

go inside and turn ignition off.

new key should work again

A solution could be to mill a second key at a local key mechanic...

or to remove the inner doorboard do have access to the lock itself where the microswitch is located

then you can turn on ignition with your key, close the door, turn the lock from the inside and so on...

you have to use some kind of a flat screwdriver to turn the lock without a matching key in the outer door hole



sorry for my stupid english

another solution would be to turn on ignition without your key, you will find a solution
