When registering keys, which number is the Kryptonite key#? I've just bought a new Kryptonite lock and am about to register the keys at www.kryptonitelock.com, but which number do I enter in the Key# box? Both? The keys each have two numbers, one LXXXX and one SSXXXXX, and they're in a different order on the big key and little keys.

(Also, I was surprised that the "Personal Password (for security purposes)" entry field on their site is in plaintext! Not very secure, especially for a lock/security company...)
I directly contacted Kryptonite customer service for an answer to this question.

I quote directly:

"The number that you need to register is just the SS followed by 5 numbers. The L code is used at the factory and is not needed."

Hope this helps!
