Hi all. Is it possible to fit a scrap ignition barrel to my Micra Tempest K11 52 plate. The current one is knackered due to me snapping the key in it and taking it apart to remove the key. (I know,I should have taken it somewhere to have it removed). I can start the car as it is but only if the chipped key is in use (any key will now turn it) The quote for a new barrel is £183 + vat so a scrap one would be preferable. How does the chipped key work? is it chipped to the ignition barrel or to the ecu?
