Seeing other people's reviews clarifies that my experience is not unique. My Kryptonite lock has served me well for years until the key snapped in the lock and I could not get it out with tweezers/pliers. I submitted a claim and have heard NOTHING. Very cheeky to claim to offer a 'Lifetime warranty'. At least tell us in the small print that it will take a lifetime to hear back from you.

⭐ 1/5 - Unreliable Lock and Unresponsive Support I am a student, and I recently had my bike stolen despite using one of [Bike Lock Company's] locks, which I trusted to keep my bike safe. As a student, my budget is tight, and my bike was essential for getting to class and work. I purchased this lock based on its security claims, but it completely failed me. I tried to follow up with [Bike Lock Company] for compensation or assistance, but they’ve been unhelpful and unresponsive, even though I provided all the required details and documentation. It’s incredibly disappointing that a company promoting their locks as "high security" won’t take accountability when their product doesn’t deliver. This experience has left me in a difficult situation, and I expected more from a company claiming to prioritize customer security. Please, [Bike Lock Company], I need your support now more than ever.

Achat d'un antivol Kryptonite keeper 785 le 23 octobre 2023 à Neuilly-sur-Seine. Moins d'un après le barillet fonctionne de plus en plus mal. La clef se casse dans le barillet. Le service après vente de KRYPTONITE est sollicité. Sa réponse est :"Après vérification, la garantie à vie de Kryptonite ne couvre malheureusement pas les dommages résultant d'une mauvaise utilisation ou d'une négligence, comme c'est le cas avec la clé cassée dans le barillet". C'est la première fois qu'on me traite de négligent. Si négligence il y avait, comment aurais-je fait pendant quasiment 1 an en utilisant mon vélo et l'antivol plusieurs fois par semaine ? Bref, très mauvaise qualité de produit. Et très mauvaise expérience client. Mon vélo est toujours prisonnier du rack vélo. Marque à FUIR !

I had my Kryptonite lock for over 15 years. The locking mechanism broke, I contacted Kryptonite, provided all of the required information and 3 weeks later I got a brand new lock. It just came via UPS. I bought the lock in New York, I now live in Croatia and they sent it, free of charge. Amazing! Thank you.

Ordered a replacement key, tooks months to arrive - replacement key doesn't even work. Tried to contacting the customer service and i got one reply after 3 months, still no resolution. They were happy to take my money for it though. Shocking aftercare, non existent customer service

Registration for ATPO failed due to a technical issue with Kryptonite's website. I then sent them a service ticket on Aug 5 with all details to register for ATPO. It is now Sep 10 and I have received no response other than an automated acknowledgement. I bought the Kryptonite lock specifically because of their ATPO program and the piece of mind it was supposed to deliver from carrying their "insurance" on my e-bike. I regret my purchase of the Kryptonite lock. In hindsight I should have gone with a competitor whose lock is better reviewed but who lacks an equivalent ATPO program.

We apologize for the delay in responding while we work through a large backlog. I have requested additional information from you so that a member of our team can assist. Thank you for your patience.

I bought Kryptonite U-Lock in April. My bike got stolen and thieft cut the lock with angle grinder in a matter of seconds. I claimed it to the company as I bought ATP together with the lock. Since then I did't receive any answer to my claim no. 109762. It looks like they cash the money from customers and do not care about holding to the terms of the ATP.
