I was unlucky enough to have snapped the ignition key in my mothers micra tempest 1.0 52 plate. I had to drill out the ignition so that any key fits it although the chip must be taped to it. She now wants to sell the car as she has bought another one. If I get a complete ignition with the chipped key from the scrappy will it work or does the chip need to communicate with something other than the ignition barrel. Clearly it isn't worth the 200 to 300 or more pounds that the dealer would charge for a new ignition. Help
