My mate has a T5 and has just renewed the batteries in his key fobs..................................now he puts the key in and all he gets is the horn blowing, anyone know the secret sequenced on how to reset the immobiliser please ?

Do you mean he's renewed the batteries?

Hello,

not sure whether you mean the key, transponder or remote control have been changed, but it sounds a bit like a transponder issue to me. You can use vag-com to get the immobiliser and ECU to recognise keys if you're really lucky:

but I'm afraid even Ross-tech don't know how to do it post 2002:

hope that's slightly enlightening
