As regards a second key you are going to need basic key shell , arm , transponder and PCB. Some programming will also be called for I would think. I strongly suggest you send a PM to Jamiewelch . See the recent thread I raised

Jamie may need the BCU out of the car – if so you get to it by removing the Glove box . There is a first rate guide by Arctic on doing this to be found at

As regards the rear headlining interior curtesy light I recently had the same problem and , as I recall, I –
• Drilled a couple of holes in the reflector area of the light housing
• placed a strip of wood across the opening , above the liner
• drove two screws ( in the holes) into the wood
This is holding up perfectly well. Was a bit fiddly re screws into the wood but once done things hold very firmly.
