How To Programme A New Key?

[The-Acre]

I've been trying to find a spare key on eBay for ages without success. I noticed today someone was breaking a 1998 car so I contacted them and they have a MK4 key which I bought for £25 + a blank to have cut etc.

Can someone point me in the right direction for doing the re programme please? All I can find is the info for an IS.

Thanks

I hope the one key you do have is the master or you will be stuck.

Thanks Ian, although that looks really daunting. Just reading through it gave me a headache.

And yes Steve, fortunately I do have the master key. This'll be interesting!

Just another thought on this. I notice some procedures include the foot pedals but the above doesn't. The headaches getting worse.....
