Had this D-lock 6 weeks before all the problems, hard to unlock can't get key out often, will not purchase from this company I thought had a great rep!!, 😔

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!@

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.

Order No. 1761943272385 from October 31, 2025 I am writing this comment because I expect my issue to be handled immediately. I lost a key for my Kryptonite lock and ordered a replacement key from kryptonitelock.com. When someone orders a replacement key, it is obviously an urgent matter. However, after reading the reviews here, I have learned that shipping can take several months, sometimes even half a year, and that communication with the company is almost impossible. This is completely unacceptable. I need the replacement key now — waiting several months defeats the whole purpose of ordering one. In Europe, it is standard to receive order updates, shipping information, and tracking numbers. In this case, there has been no information at all since I placed the order.(except for the order confirmation) Therefore, I demand that my order be cancelled immediately and my payment refunded unless the key is shipped and delivered no later than November 12, 2025.

I ordered a replacement key on August 20. One month later I asked for an update on the order. I received a response that the key would be sent the following week. No Key. Three more requests for status have gone unanswered. It is now 2 months since my order and no key, no update. Irresponsible customer service. (Conf. #: 1755693838510) Update: After posting this review on Trustpilot, I was finally contacted by Kryptonite, and they quickly sent me a replacement key and apologized for the delay. They also committed to refund my original payment, but I do not see that they followed through on this. In any case, I appreciate that Trustpilot provided a platform for getting this matter resolved. New Update: Kryptonite did credit me as promised. I missed it upon review of my statement. Thanks for the follow-through.

The most klunky, difficult to lock bike lock I've ever encountered. Had it now for over a year and I have problems with it everyday. Time to get something more bicycle friendly and easier to use.
