KRYPTONITE Recenzje 

Amazing warranty. So fast and easy

Great product - industry leading for a reason. I wouldn't trust my bike to any other lock. Fantastic customer support.

Great customer service regarding warranty claims

I purchased a Kryptonite D‑Lock a few years ago—it wasn’t cheap, but it was worth every penny. Recently, my original lock stopped working, and Kryptonite replaced it with a brand‑new one under their lifetime guarantee, no hassle at all.

The lock itself is excellent: sturdy, reliable, and gives real peace of mind when securing a bike. But what impressed me most was the customer service. Their team was responsive, helpful, and made the replacement process effortless.

I’m extremely happy with my purchase and the support I received. I strongly recommend Kryptonite—not only for a top‑quality bike lock, but also for customer service that truly stands behind its products.

Thank you for immediatly replacing my lock that, after 3 years of use, had started to disfunction.
Fantastic service.

Best, Patricia

OLEH was fantastic. Got straight back to me - service with a big smile. 10 out of 10. WELL DONE GREAT JOB

I have bought Kryptonite locks for a long time now and recommend them. However, this review is based on my contacting Kryptonite customer support over a failed lock. After sending them a message including the required photos, I was contacted next day by Oleh, Customer Services. After checking I had tried possible solutions, he arranged a replacement. It arrived from the USA to here in the UK in four days, less than a week from me raising the warranty issue.

This is absolutely the best 5* customer service I could expect and fully justifies both my own purchases and the recommendations I've made to many other cyclists.

When I wrote to Kryptonite about small problem with my lock, I was hoping they could sell me a replacement part. Not only did they reply quickly and helpfully, but they offered to send me an entirely new lock, free of charge! I did not expect this, and it surpassed all my expectations.

I've had bad experiences with other companies who wiggled their way out of warranty coverage. But this was NOT the case with Kryptonite. What a great experience! What a super company. (I would also recommend their instructional videos - which are very clear).

My lock developed a fault and I had a warranty replacement shipped out to me within 36 hours.

Had a problem with my old lock and the customer service team was easy to work with and they were on top of it.

Thank you Oleh

Good quality lock. Responsive customer service for the theft insurance.

Kryptonite support genuinely went above and beyond for me — they reviewed my case, explained the ATPO requirements clearly, provided the bill I needed for registration, and even arranged a replacement chain so I could register properly. Oleh in particular was incredibly helpful: responsive, patient, and very cooperative throughout the whole process, and he made a stressful situation much easier to deal with.

Best service I have ever had in my life,
No questions asked, just sent a replacement lock, this thing is like $70

Oleg was perfection!

I just received the mini u lock w/key safe. THERE IS NO INSTRUCTION OR VIDEO ANYWHERE, NOT EVEN ON YOUTUBE. There's no discernable place to open it; there's no way to find where the keyhole goes if you cannot even open it. THIS IS STUPID. It's the 21st century and Kryptonite can't get a how-to video for each of their locks? THEY SURE HAVE ENOUGH MONEY!@

The customer service rep on the phone was so helpful and very nice. His name was Oleh and he made the process of helping me with my lock quick and easy.

Not just one kryptonite lock issue I have had but two

Both became troublesome with the key and lock mechanism not working all the time despite oiling it.

Will try alternative locks in future.

Worth nothing. Had kryptonite lock on my bike only took 2 minutes for a guy to cut it off with a wireless saw. The lock was rated 7 or 8/10.

For a company whose brand needs to be based on reliability and security, it has been a disappointment. The locks work fine, but their customer service and operations do not. Our locks came without the rewired tag ## to register the locks and bikes, we never received a promised email confirming we had registered our bikes. and simply trying to replace one of the registered bikes with a new one is now up to three unreturned phone calls and three totally illogical emails where someone clearly cannot pay attention to what is being asked.

Great service on replacement keys. Ordered 2 keys at end Oct 2025, keys depatched from USA on 5 Nov 2025 and arrived via post in UK on the 11 Nov 2025. 3 weeks from order placement on line to receiving keys in UK.
