    Put the key in your vehicle's ignition and make sure all the doors and the boot are closed.

    Turn the key two clicks to the right, one click short of the "Start" position before you do anything with your replacement remote.

  3. 3

    Press and release the "Override" button on your remote car alarm remote five times in less than eight seconds.

    Remove the key from the ignition and test your remote.

Tips and warnings

  • Be careful not to do this without having an extra set of keys for your car; you don't want to turn to a remote replacement after you're locked out of your car. It should be a backup, ready if you lose your primary car alarm remote.
