I have lost the spare key for my Mk1 2.3 It was the one without the remote buttons. I assumed that this was a normal key blank but Timpsons told me there was a chip in it. They said a normal blank would be £10 and not start the car and a programmed blank will be £30 and will start the car. Am I being led down the path here ? Does a non remote key have a chip in it?
