hello all, just purchased a s plate rover 220 diesel injection, and after 3 days my handset has quit unlocking the car and deactivating the imobilser!! can only guess its the imoboliser as the red flashing light isnt on the dash either, yet when i unlock the car manually, and try to start the car, it sets the alarm off! where is the imobilser? the fuse for it? where do i get a new one?
