Hi
When i got my ten i got given these 3 keys (plus the red one). The one in the picture with the bolt through i actually found bolted to the bike when doing some work once
But only the big black one (with the Yam logo & i guess the red one) will actually start the bike. The other key will turn the engine over but is retarded by the immobiliser. The immboliser light stays flashing while using these keys but when you use the black key the light goes out. (and the bike will start)
So when your out and about....if you loose your black key....your basically ****ed then????
(ive never owned a bike with am immboliser.)
