Review: Excellent and sturdy lock, do not lose your code number - Great and very sturdy. Make sure you keep your documentation with the unique number of the lock on it so that if you lose the key as my careless kid dead, you can get another one from the manufacturer! :)
Review: Key-less! Love it! - I love this bike lock because it is keyless. I have deliberately eliminated as many keys as possible in my life and this was one important purchase in that effort. I commute on my bike regularly and now this bike lock lives on my daily commuter bike. I never have to worry about losing the key, and always have access to my bike when it is locked by remembering a simple 4 digit code... a code which I can reset whenever and as often as I like, very easily. The mount which affixes the lock to my bike works very well, though I did have to play around to find the best position for it. Thankfully it is rather adaptable. I hope I never need to, but I would buy this lock again if need be, and I would certainly recommend it to anyone who needs a bike lock, especially if they are trying to live a minimalistic, key-less lifestyle.

### ⭐ Brand new lock is DOA and Kryptonite support is AWOL
*by J***C on September 3, 2025*

I just received a brand new Kryptolok Combo and it does not open with 0-0-0-5 as it should. I have also tried 0-0-0-0 and 1-2-3-4 and other standard combinations, but nothing works. I have tapped the lock repeatedly with a rubber mallet according to the support page recommendations. I have sprayed pure silicone into the mechanism. I have sprayed Houdini. I let it sit out in the sun. I used a rubber mallet and a screwdriver to try to push the lever to the left with more force. I have tried to reach Kryptonite by phone and they don't respond to voicemail messages. I have tried to use the online Kryptonite support resources but the form that I have filled out multiple times has failed to send each time because of some requirement that I "read the disclaimers" that don't seem to be accessible from the form or because the form requires me to provide the key number (for a combo lock?!) or some other nonsensical requirement. This is clearly a company more interested in creating obstacles for customers than solving their problems.
