Basically, I'm here as the 56-reg (UK) Passat B6 I bought only came with one key -- I've bought a spare one from eBay, and I'm trying to work out how to reassign the spare to the Passat. Not a simple job, but I really want to avoid paying the dealer the best part of two hundred quid!

Welcome! FYI, I think 2006 was the last year they had non encrypted immobilizers so you should be able to assign it. However, since you have immobilizer 4, you can't assign used keys, so if that key you got off ebay was previously assigned to another car, it won't work on yours for the immoiilzer.

Ah. Thanks!

It looks like the eBay key is used -- since the key inside is cut for someone's car.

However, I have been reading of VAG-commmander and things that be able to get the immobilizer to accept the key -- but assuming that I got hold of a cable, the software, if I screw it up, that's thousands to fix!
