    Questions & answers

    Electronic immobilizer — Volkswagen Golf Mk7

    How does the Golf Mk7 electronic immobiliser work?
    A chip in the key transmits a code when the key is inserted or detected by Keyless Access. If the code matches the vehicle's stored data, the immobiliser releases and the engine can start.
    Can the Golf Mk7 be started without the correct key?
    No. The immobiliser prevents the engine from cranking with an unauthorised key. Even a correctly cut blade that fits the lock will not start the engine without the matching electronic chip.
    What does the Golf Mk7 immobiliser warning lamp look like?
    A key symbol in the instrument cluster. It flashes briefly during normal operation. If it stays on, the system has not recognised the key — try reinserting it or using the spare.
