flashing key light on dash

  1. #1
    hey guys
    had a quick look up on this and believe this is to do with the immobiliser! my car works fine and starts everytime but the remote locking works one minute but not the next . is the flashing light purely to do with the immobiliser side of things or would it indicate that my key fob is broken??
    Like i said it doesnt cause any other problems just annoying flashing all the time

    cheers kc

    Is your ECU unlocked?

    Theres an immobiliser relay underneath the ECU, replace that? (only like £3 iirc)
