WHAT IS THE ANTI-THEFT PROTECTION OFFER?

Kryptonite stands behind its products by providing an Anti-Theft Protection Offer on specific locks. Created by Kryptonite in 1978, the Anti-Theft Protection Offer is a program that reimburses registered customers for a specific monetary amount in the event their bicycle/motorcycle is stolen due to the opening or breaking of the lock by force. ATPO coverage is not bicycle insurance and there is no affiliation with an insurance company. The offer is administered by Kryptonite.

To locate the ATPO coverage amount, look for the sticker on the front of your Kryptonite lock package, or check kryptonitelock.com. Remember, this is an OPTIONAL offer and you MUST register to participate in the Program. To be eligible, a customer must register online at the Kryptonite website within 30 days of lock purchase.
