Great staff and customer service!

Sending a replacement lock after it was cut by a thief - very good service!

Kryptonite has an absolutely incredible customer service team! A thief attempted to steal my scooter, but I showed up just in time to catch him in the act. Unfortunately, he had already sliced through my Kryptonite New York U-Lock (unfortunatly every lock can be broken with the right tools). However, thanks to the double-bolt design, even after slicing it, he simply couldn't pull it free. The lock did exactly what it was supposed to do and kept my scooter right where it belonged. Since the lock had proven itself so well, I wanted to replace it with the exact same model. It's a bit on the pricier side, so I decided to shoot my shot and reach out to Kryptonite directly, explaining my situation and asking whether they might consider sending me a free replacement. I was completely blown away by the response I got. They acknowledged that don't typically replace locks damaged during theft attempts, but given my particular situation and the fact that the lock had so effectively prevented the theft, they said they'd love to send me a one-time replacement out of goodwill, to help keep my scooter safe. I just received a brand new lock, purely out of the kindness of their hearts. How incredible is that?! A massive thank you to Oleh and the entire Kryptonite customer service team for empathizing with my situation and going above and beyond by making an exception to their usual policy. I cannot appreciate it enough!!!

Spent decent amount of two locks last year. Both jamming even when oiled. My wife has the same problem. Spent 45 minutes trying to open my lock and a guy walking his dogs starts chatting to me and says the exact same thing has happened to him. Binned the lock. Have nearly always used kryptonite locks in the past, totally lost faith in them

Amazing warranty. So fast and easy

Great product - industry leading for a reason. I wouldn't trust my bike to any other lock. Fantastic customer support.

Great customer service regarding warranty claims

I purchased a Kryptonite D‑Lock a few years ago—it wasn’t cheap, but it was worth every penny. Recently, my original lock stopped working, and Kryptonite replaced it with a brand‑new one under their lifetime guarantee, no hassle at all. The lock itself is excellent: sturdy, reliable, and gives real peace of mind when securing a bike. But what impressed me most was the customer service. Their team was responsive, helpful, and made the replacement process effortless. I’m extremely happy with my purchase and the support I received. I strongly recommend Kryptonite—not only for a top‑quality bike lock, but also for customer service that truly stands behind its products.
