KRYPTONITE Opiniões 

They are too lazy to even provide any instructions of how to mount the lock on your bike and instead just point you to their youtube page and expect you to go hunting for it. Haven't even used the lock and I don't like this company

I've been using a couple of Kryptonite locks for years — some for over 15 years — without any problems. Recently, I ordered additional keys for three locks through the Safe Key Program, and it only cost me €7!

Three weeks later, I received six perfect keys in my german postbox.

I really trust Kryptonite, even if customer communication isn't their strongest point. This program is awesome and yet another reason to recommend this high value products!

I've used these locks for years because they're secure and fix soundly to bike frames.

Recently needed to replace a couple of keys. One set arrived and worked great. They didn't have the blank for the second set so they sent me a whole new lock.

Friendly, great lock, great customer service.

Appalling have not heard back from them sent about a dozen emails about my claim have not even got a response would avoid this company for future reference.

My claim number is Claim Number: 110658

I ordered keys for my lock directly from Kryptonite.com. Two of the keys did not work. I submitted an online request for a refund and never received a response. Phone calls to the companies number go straight to voice mail and are never returned.

Kryptonite hat mir Anfang April 2 Ersatzschlüssel für 45 USD inkl. Versand verkauft, danach gab es keine Reaktion mehr und auch keinen Versand. Ich habe ein Ticket eröffnet und erhalte keine Reaktion, nachdem sich vor 3 Wochen jemand für meine Geduld bedankt hat.
Eine Klärung über Amazon, wo ich das Schloss gekauft habe, aber über die es keine Ersatzschlüssel gibt, ist nicht möglich, weil die Bestellung nicht über sie lief.
Also niemand ist zuständig, Reaktionen gibt es nicht, und ich muss mir ein neues Schloss kaufen. Finger weg!

Update 25.6.: Gestern kamen die bestellten Schlüssel an, und sie passen auch. Zwar weicht der Preis auf dem Lieferschein deutlich von der bezahlten Summe ab, aber was soll’s. Danke jedenfalls - ich ändere auf 2 Sterne.

I've made a claim on the 3rd of April 2025 and they have not replied yet. The confirmation email clearly stated that someone would get in touch. It's now the 11th of May. This is ridiculous. Claim number is 110600

trash. their locks are not good and they will do everything they can to avoid paying you the anti theft protection
ridiculous and AVOID

Submitted a claim an no response! Claim number - 110617

Suite à achat antivol Evolution. Fait le job. Attention cependant, comme tout autre antivol, il se vole en quelques dizaines de seconde (mon vélo précédent a été volé à l'aide d'une barre en métal servant à faire levier). De plus, l'assurance additionnelle (moyennant paiement) ATPO proposée exige pour fonctionner que vous transmettiez une photo de l'antivol coupé / cassé (cf les CGU sur leur site) ! Il est évidemment rarissime de le retrouver. Ne tombez pas dans ce piège commercial.

GOOD LOCK, YOU DONT RECEIVE LIGHTED KEY WITH ORDER AS STATED BUT YOU CAN CALL CUSTOMER SERVICE AND REQUEST THEM TO SEND ONE.

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.

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.

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.
