When I got my 08 reg 197 it came with 2 key cards which worked fine keyless as they should, unfortunately I lost 1 of the cards so I bought a non OE replacement and got a locksmith to program it for me. The new card worked fine but not keyless and the worst bit is it killed the original card I had left, now I’m left with just one key which I have to put into the slot to use and press a button to unlock/lock the car. I know replacement OE keys are very expensive so I was wondering if I find someone breaking a 197 and I was to buy the key cards, uch and ECU from them and fit them to my car would I end up with a working system or would I just be setting myself up for a load of problem?
