Not sure if there's another route for the dreaded Car Pass... have a feeling the cost varies depending the mood of each individual stealer... as for keys, this cost can come down dramatically, the new fob, for starters can be got from a breakers as a freebie in your pocket, or off here for beer money, or ebay (in the form of slightly inferior quality, but perfectly good as a spare) for literally a few quid. Programming, your local keycutter / market stall that does phone unlocking, etc.. should be able to help. Have a feeling that there's two 'bits' ie: - the immobiliser 'bit', and the remote central locking 'bit' - the remote central locking function can go when you replace the battery, and can be easily reprogrammed by yourself inside the car, as per the manual. The immobiliser bit is the only 'specialist' element, but hardly advanced or difficult, these days, the design being approx 20 years old.
Ask around, independents should be able to do this a LOT cheaper. Seem to recall something like £30 when the old man had himself a spare made up?
