I just got this:
"We have begun sending UPS call-tags to participants for their use in
returning their Kryptonite tubular cylinder locks,
and we are preparing to send their replacement locks to them.
This is being done on a first-registered, first-served basis.
If you've not yet received a call tag from us, you should be receiving one soon."
I read it to mean the order in which people registered for replacement. I never registered my keys either. Haven't gotten the call tag yet, though.
