Are the clocks brand new and never been fitted to a bike?
If so you need your red key and at least two black keys to code them to the bike-when you turn on the red key you start a countdown and you then have to turn on each black key within 15 secs and finish again with the red one turn on and off within 15 secs and wait 30secs before turning any key on again.
If they have been fitted to a bike then you have had it-they are already coded to whatever bike they were fitted to
