I received a replacement bike lock for a defective lock under warranty. I did not expect a new lock being sent which was really awesome. I have always used Kryptonite locks for my bike for years and can attest to their quality products and service.

I purchased a New York Lock M18-WL, in February 2026 but come April the key is already jamming, or failing to fully insert into lock barrel so I can’t rely on this expensive product to actually serve its basic purpose! The lock is 60 days old and it’s never been left outside! Key Number: PP 9804

Hey, I wanted to share a quick real-world experience, I had bought my first E bike and was on my very first ride when I was hit by a hit-and-run driver my kryptonite lock flew off the bike rack and ended up getting run over by cars in the opposite lane. It was banged up but it still worked, and the good folks and kryptonite replaced so I wouldn’t have to have a banged up lock ! And I thank them very much , and to everyone at the kryptonite team in Canton, Massachusetts. You’re the best and so your locks. Sincerely , Jason Blauner ( Dorchester ) mass .

Kryptonite kindly sent me a replacement lock after my key snapped off in my lock. Sadly unable to provide a refund for the cost of removing the lock as I couldn't provide photos of the cut lock but they gave me the benefit of the doubt on the replacement lock which I'm grateful for Small criticisms: 1. There is no clear way of raising this kind of request on the kryptonite website so I had to raise it under warranty issues 2. Due to this lack of clear pathway, and the fact that it took them about a month to get back to me, I threw away the cut lock on the assumption nothing was going to happen. Obviously, should have taken a picture but a month is ages in customer service terms. Still-grateful for the replacement lock

The padlock is amazing. Unfortunately, I think I received one with a minor defect, so after a few months of heavy use, it broke. However, customer support helped me out and we resolved the issue. In my opinion, they are the best.
