Re programming key to mk5 gti

Hi all
Have two keys on a recently bought mk5 gti, one of the keys must have been flat for a while. Replaced the battery but am unable to get the key working with the central locking. Tried the ignition on, inserting the new battery key into the drivers door lock, pressing open, twisting the key to lock, then twisting the key to unlock. Doesn't seem to work. Is there another way?
Cheers Nardoblue

 

Cheers for the reply, mine said , go to the car press the unlock on the remote and insert the key into the door lock straight away, unlock the car. Should be re synchronised, no didn't work.

 

I'll have to speak to some one at work that has VAGCOM, the key opens and starts the car, the red light lights up when pressed.....

 

What is your location?

 

Just off junction 11 m40. North Oxfordshire buddy.

 

I have a full vagcom, I'm in brackley should be quite close to you. Welcome to use it if it helps, though I don't know the process to reset the key.

 

Thanks for the offer bootsie, I'll contact you when I get back off holiday in a couple of weeks time if that's ok, just over at Chacombe, cheers Rod
