Forgot to mention, once you have programmed your new key to your existing key they will be the only 2 keys that will work.

So if the stolen key was used to try and start it, you could unlock the bike obviously but the fuel pump doesn't prime.

Found this out by accident, bought my Fireblade off a mate with only one key, bought and programmed the second key.

My mate finds the spare key so now I have 3 keys, but this one no longer works, fuel pump doesn't prime.

If I want this key to work, I have to program all 3 together. I'll get round to it one day.

So say I had two keys to start with,. original keys. If I buy another blank key from David Silver for example and go through the process you kindly posted above, I would have to re-code my second orig key along with the new one and this would work? I thought the chips in the keys could only be coded one time.  I guess the code is the same in both the orig keys, but you found out the found spare key would no longer work.  Is there a time limit on doing this whole process? I read somewhere has to be done in 10 seconds.
