    My key won't turn and no zzzzzz mechanical noise when inserted.
    I believe its the infrared type with RF door unlocking.

    Can I disconnect the car battery for a reset of the receiver on the lock area?
    What problems could occur when i reconnect car battery?
    Alarm goes off?
    Can live with the ECU re-learning driving style.

    I don't have a second key:(

    Also aware I might have to buy a new key :devil: £150:devil: :devil:

    Update.
    Disconnected the battery for an hour, no change.
    Car locks and unlocks OK, no noise when I insert the key in the ignition.:mad:

    Is there a fuse for the Immobilizer, or is it OK as I can lock/unlock, I.E. there fed from the same source or same unit?

    Starting to get worried now ££££££:(

    Perhaps a bit more than £10 to make it but most of the cost you pay for comes from the secure process of ordering/delivering a new key, from the hours people spend on your individual new key. Of course a spare part margin on top of everything.

    I was really worried it was gonna be the EIS.
