It was a fantastic experience - so smart and friendly in helping me...

Great customer service. Thank you

La serrure n’arrête pas de se bloquer.
Impossible de l’utiliser une fois sur 2 !
Quelle daube

I used the standard Keeper U-lock for years and was very happy with it. When the locking mechanism broke, they sent me a new lock. Customer service was prompt and polite. I'm very happy withy experience.

I purchased the Kryptonite Evolution 790 Folding Bike Lock 90cm expecting a premium product and reliable customer support, especially at a $150+ price point. Unfortunately, my experience has been extremely disappointing.

The Click-Tight bracket/cradle failed and would no longer release the lock. The lock became stuck in the mount, and I actually damaged the lock trying to get it out. I opened a support ticket with Kryptonite and spent over a month trying to get help.

Communication was very slow, often taking weeks for responses. After finally acknowledging the issue, they shipped me the wrong replacement part entirely. When I expressed frustration after more than a month without resolution, I was told I would not receive a replacement lock or refund — only another bracket.

To make matters worse, the case was eventually closed without the issue being resolved and I never received the correct replacement bracket.

For a company that advertises a lifetime warranty and premium security products, this level of customer service is unacceptable. The lock itself may be secure, but if the mounting system fails, the product becomes unusable. I cannot recommend this product or Kryptonite support based on my experience.

Kryptonite Kryptolok Long Shackle U-Lock was not fit for purpose. I cycle on tracks and rough ground, this causes the levers in the lock mechanism to become loose. This prevents me from fully insterting the key so I cannot opertate the lock. After a few minutes of manipulation I can operate the lock. Did not try for Warranty as it does work if you have time to mess about.

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.

El candado se averió y tras una rápida gestión de garantía, me enviaron uno nuevo en menos de 5 días.

The staff were helpful and supported me in resolving my issue. Very grateful.

Fast and knowledgeable service. Kryptonite stands behind its products.

Very responsive and trustworthy company. They replaced my U Lock that was damaged with a refund and full lock replacement.

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.

Kryptonite est une marque qui n'a plus rien à prouver en ce qui concerne la solidité de ses antivols et de son service après vente, si vous voulez prendre soins de votre vélo et garantir la meilleur sécurité je vous conseille vivement de prendre un kryptonite ! En particulier le kryptonite evolution mini 7 qui est excellent ! Merci au service après vente notamment Oleh qui a su répondre à toute mes demandes. 💪🏻

Kryptonite Support was quick to respond and thoroughly professional regarding my case. I am extremely impressed by their trustworthiness regarding warranties and commitment to customers! TOP RATING for this company

I recently had an issue with my Kryptonite Evolution 1016 chain lock where the internal mechanism seized up. Since the lock was a few years old, I wasn't sure how difficult the warranty process would be. I reached out to their customer support and was assisted by Oleh.

The service was exceptionally fast, professional, and completely hassle-free. After providing my proof of purchase and a couple of photos, Oleh immediately approved a brand-new replacement lock under their Limited Lifetime Warranty. It is rare to find a company that actually stands behind their products this solidly. Thank you to Oleh and the Kryptonite team for the amazing support!

Oleh was super helpful for a replacement lock

Easy to communicate with service for replacement when the lock failed while under warranty. Thank you 🙏🏾 Kryptonite!!

I bought a Kryptonite New York Lock with my bike a few years ago based on their reputation. My bike was never stolen !
After a 4 years of keeping my bike safe, the mechanism of the key got gripped stuck, hence, the lock was unusable.
I contacted the customer service and, one week later I had a new lock that was sent for free as a replacement of my lock. They are very efficient !
