Speed Triple R 2015 Fuel Cap

hi, I have a 2015 speed triple r, it came with a different key for the fuel filler cap, I do not like this, I would like to make the ignition key work the filler cap.
Can anyone advise how to get the lock barrel out of the filler cap so I can swap or remove some of the tumblers hopefully allowing the ignition key to turn it ?

 

That’s my next step, if I can get the barrel out I can make it so any key will open it, which is fine. Just trying to do it without spending as I am broke after buying the bike
