What about if you have no second key and want to add one? Dealer only?
I want to add a second key when I get the chance as long as it's not too expensive. From the research I have done it's quite easy to get a blade cut and sync the remote central locking, but it's the RFID immobilizer which causes the problems. I *think* it may be possible to buy a blank RFID chip and have a local auto locksmith clone your current one?
You can do that, yes. The local auto locksmith will clone your functioning RFID chip to your blank one.
This is a chip that can be used: http://www.ebay.co.uk/itm/291274140896
Any
locksmith can make a clone key or there are some specified locksmiths.
