How to - Resync your keys / Change key battery

IIRC - Vagcom cannot do key SKB(??) code retrieval.

I've had a look on mine and it isn't apparent.

I think there is another bit of software (dos based) that is needed to acquire the code for the immobiliser. Alternatively, I have heard that VW keep a record of all codes applied to each vehicle which a UK dealer will get from them.

Correct - you need VAG KOMMANDER or Vag Tacho to retrieve the SKC code from the clocks.  Although the latter is not very reliable on Bosch clocks; VDO clocks tend to be far easier to work with 

If you're extremely lucky you'll have the plastic key and tag that came with the car as the tag has your SKC on it

sometimes your remotes can lose their coding with the car meaning your remote won't lock / unlock but there is a solution 

Worked for me - took less than a minute and saved me a few quid i am sure. My car came with two keys one of which had never been used. i used to have a renault card key and had visions of a similar nightmare rebooting the key. No such problems with the VW. Great tip many thanks.

Hi i had this issue my problem is i have no hidden keyhole. My guess is previous owner removed it (dont ask me why) so my question is is there a way without going to dealership and without using a second key? Can i do it through the lock on boot both my spare and main are not working
