Kryptonite Keeper 12 Standard with Bracket Black

The media could not be loaded. A quality product at a nominal price. I have to bought this as my old lock from Halford decided to not work anymore. It’s lighter than my old lock. In my use case I wished if the bracket was a little smaller, as I needed to mount it on the side of frame close to wheel.Comes with two keys. You do feel a little bit rattling when it’s mounted on the frame.

The lock itself is very sturdy and more than adequate for my needs of locking a bicycle outside a supermarket. It's quite weighty and feels robust.Opening the lock was initially a bit fiddly but once used to it, is no deal breaker.The keys can be registered and, allegedly if you do, you'll receive a free replacement set if you lose the two supplied keys.The lock is supplied with a bracket to secure the lock to a bicycle frame, which was a key feature for me, and the holding bracket has a quick release system - simple button. But mine was supplied with the bracket fixing bolts and washers but no securing nuts which is both very frustrating and says something about their shipping quality control.Such a shame that my opinion of an otherwise good product is skewed because someone couldn't bother to check the product pack list. :(

Bought this a few days ago to replace an OnGuard combination D lock that failed (the combination seized up, fortunately as i was about to fit it to my bike).This lock looks good, it's not too heavy and I eventually managed to fit the bracket to part of my bike. The business end of the keys don't look too sturdy so slowly and carefully locking and unlocking seemed to be the key (!).I already have a cable from the OnGuard purchase so i will incorporate this with the lock. Looking forward to using it when it stops raining.

Bought this when I got my bike and I always feel so safe locking it up anywhere. It feels sturdy, rugged and heavy!

It's definitely not a top-secure lock and I wouldn't expect this to last for long if it's exposed to rain or snow. Also, it can be a bit noisy when mounted on the bike. However, it's more than good to prevent opportunistic thefts. I would totally recommend this for a low-end bike, but for more expensive bikes, I believe kryptolock or evolution series are more trustworthy.

When I first got my lock the key was really really stiff so much so that it was taking me about 5 mins of fiddling and the key bending to actually get it unlocked.I oiled it a number of times and after continued use the bit of metal that was causing it to be so stiff seems to have worn down and now works perfectly.The key is not very strong and due to it originally not working and being very frustrating I’d says it’s a cheap lock.The lock however is very strong and the attachment that clips to your bike is also very handy but if your bike frame anything other than cylindrical then it won’t fit very well. Note that it works fine I have no problems with the lock.

Had I read any reviews I would have bought a different lock.Pros:Discreet, robust, and compact.I especially like the included bracket for mounting the lock to your bike frame when cycling.Cons:KEYS - Inserting the key and turning the lock in a swift fashion is not something I'm able to do with this lock. It takes several attempts to get the key all the way in, then a few more attempts to successfully turn the lock open or closed. This dramatically reduces its value in my eyes.With the lock containing several internal components, when cycling over bumps, even with soft landing off the curb, these internal components make a hell of a racket, which after a few rides can get a bit annoying.Overall I think its ok value for money, the brand is reliable and nobody has tried to steal my bike... Yet.Personally I would try to find something that didn't rattle when attached to the frame, and that allowed for a smooth locking and unlocking.

I could not stop the lock from moving side to side when attached using lock hanger to the bicycle, vertically, due to frame thinness of my bicycle. But overall happy with weight (heavy) and build quality.Update 10 February 2020, the lock is now 11 months old, still now issues and it works in every possible way.It fits into my bag perfectly, so I have stopped using the lock hanger. The lock was used on around 150+ rides in different weather and still functions as in the day one.
