Regarding Kryptonite keying, I've bought locks from Wiggle in the UK and they have different information on the colored label tubing.

Such as:

"Sold Secure Gold"
"VdS Klasse A"
"VdS Klasse B+"
"Art 3115 (with 1-5 possible stars)

I know it's unlikely Kryptonite would honor a US claim for a UK lock, but is other country keying different than the US? Just curious, because I know there is still a master key that looks like a portable angle grinder.
