The key starts the bike very well, and it sits firmly into the lock.  However, I suspect that the tumblers inside the lock cylinder may be worn, damaged or the lock cylinder has failed.  I can start the bike, take out the key, and the motor will still run.  Now this is scary in many ways; for example, on a bumpy ride the key can eject; I will have no way of knowing when and where this will happen. 

I spoke to a Yamaha mechanic who  seem to suggest that I have to change the ignition assembly and also the  ECU that is linked to the immobilizer.

However if you look at the diagram attached, all I seem to need is 31, but it seems reasonable to include 32, new key, and 33,34,and 35 for aesthetic reasons.

I am aware that a new key will imply also changing the locks for the seat and any other associated locks( in my case only the lock of the seat.  I do have the original red key which allows me to duplicate new keys without having to change the ECU.

Your guidance please
