Really horrendous experience with this company. Purchased a lock with Anti-theft protection just to have piece of mind that if something did happen I'd get some sort of compesenation to be able to buy a new one. That day came when someone cut my lock to steal my EBike when I was at the gym one day. As soon as I filed a claim the first reed flag was that they state it takes 30 days for them to respond. Then after finally responding they refused to pay because I couldn't send a picture of the broken lock that the thieve must have took with them -- despite sending the police report with the stated events and CCTV footage. Can't believe it, simply do not buy from this company.

I took out ATPO insurance with Kryptonite, I had a claim at the end of December, I sent all the requested documents but the only thing that bothers them is knowing why it took me so long between buying my bike and buying the lock (6 months) except that I already had one but it was defective so I bought another one in December. Since then Sandy has been playing dead, she hardly answers emails, I am going to start a process to be compensated, it is unacceptable. Ms. Maillard

My claim (Claim Number 110308) was approved over two months ago. While I have received the settlement figure, I have yet to be paid despite repeated assurances that payment is "being processed." This delay has left me extremely frustrated. I rely on my bike for daily activities and work, and being without it for this long has caused significant inconvenience. Customer service, which was initially responsive, has now stopped replying altogether. The lack of communication and action is deeply concerning, and I would strongly advise others to avoid this company. It’s simply not worth the hassle.

Sounds like a story of many. Lock broke; contacted them for a new one under warranty. Very delayed response asking for the inside lock size; after that, zero response. Big promises, and big expectations; no delivery. £15 bike lock from a local London shop has lasted longer with much better customer care.

Non-existent customer support; no response to several requests (réf. 493733 about APTO anti-theft protection program). It's deplorable; I've never met a company that cares so little about its customers.

Nu har jeg i 2 år benyttet mig af en Kryptonite forsikringsgodkendt kraftig kædelås. Låsen har fra første færd været super besværlig, at åbne og lukke med den tilhørende nøgle. Nu sidder nøglen fast i låsecylinderen, for jeg ved ikke hvilken gang, denne gang kan jeg ikke få nøglen ud og nu har jeg givet op på låsen. Jeg køber ALDRIG igen en kraftig kædelås eller andet af mærket Kryptonite, låsen har vist sig at være af tvivlsom kvalitet.

I recently had two occasions to contact customer services. One was for advise on how to fix the barrel on my lock which had jammed & after showing digital images of the problem I promptly received a new lock FOC. Then I needed to order a replacement key for another lock & after a problem with their site meant my payment could not be processed, they said they would process my request FOC. Prompt & efficient service.
