Kryptonite shipped me a replacement lock when my lock was cut and bike stolen then recovered. The process was relatively easy and the customer service rep, Oleh, was very helpful! I got a new bicycle recently, and I got a Kryptonite lock and ATPO for it as well.

Katastrophale Qualität, wurde ich nie mehr kaufen - wird suggeriert, dass das diebstahlsicher ist, hat keine 20 Sekunden gedauert und das teuerste Keyptonite Schloss war auf geknackt...

I purchased a Kryptonite New York Diamond lock from an online vendor that turned out to be from one of the early production runs that were vulnerable to angle grinders where the shackle meets the crossbar. I contacted Kryptonite and with the help of Oleh in customer support, sent the vulnerable lock to Kryptonite so they could replace it with a new lock. After giving Oleh the serial number from the bottom of the lock, I was promptly provided a return label. Once my return reached Oleh, he quickly had my replacement out for delivery. I received the replacement lock and am very happy with the new one and with the service I received.

Their warranty scheme is incredible as they refunded me for a locksmith to come and cut the lock as well as that they send me a brand new lock.
