I finally got my email from Kryptonite to send my lock away via UPS. This must have taken 4 to 6 months. I haven't recieved a new lock in echange though the mail yet though.
If you haven't got your email from them yet you may have missed it. It states that you have 10 days to download the bar code that you need to mail it.
Reregister with them if you think you missed or deleted their email.
