I was honestly surprised by how easy the process was. My lock stopped opening, and customer support was very helpful and quick to respond. They approved a replacement under the lifetime warranty right away. It’s nice to see a company that stands behind its products. Thank you

You know my dealings with this company they are always top when it comes to customer service. They just can’t be beat and their products are always fantastic.

The lock does lock up your bike, however it keeps it locked when you put the right code in which isn’t very helpful.

Ordered and paid for a duplicate key for front brake disc lock confirmation # 1780453393811 and never received the duplicate key. Contacted Kryptonite and was told it would be shipped this week and that was 3 weeks ago. As a motorcycle locksmith for the past 20 years I cut keys and ship on a daily basis but do not have the equipment to cut this particular key and have little call for it.

I registered my New York Diamond lock after the 30-day registration period had passed. The lock was originally purchased as a gift, which unfortunately meant I was unable to register it myself within the required timeframe. After contacting customer support and explaining the situation, they reviewed my case and made an exception so that my registration could be corrected with the proper purchase date. I really appreciate the helpful and understanding support. The process was handled professionally and quickly, and it has reinforced my confidence in both the product and the company. Thank you for the excellent customer service.

Maybe an excellent lock but customer service is up there with the worst customer service over a month to reply and as a result would never purchase their product again
