I have noticed a small crack develop in one of my buttons on the ignition key. I asked my dealer for a price for a new casing and i was told that casings cannot be bought separately - I need a whole new key at £227. Does anybody know if it is possible to swap the innerds from one key to another (if I can source a good 2nd hand key from another car)? And, what is the cheapest way to get a whole new working key for my car? Is there any other way that is cheaper than the dealer price of £227 (eg re-programme a key from another car)?
