If you bought the generic lock, depending on the type of key it uses this may be possible. I'm not a locksmith but I am somewhat addicted to Bosnianbill and Lockpockinglawyer on YouTube.
These locks can come apart. Just make sure you do it over a large pan to catch any springs that may fly out.
Even if you have to file out the inside of the cylinder to make your Kawi key work and use less wafers it's ok. I doubt anybody will try to pick a helmet lock to take your helmet. It's a crime of opportunity. A thief will go on to steal the helmet which is just resting on top of the mirror.
I use a thin cable around the chin bar then attach it to the lock.
