Kryptonite Chain Key Chain - 8mm: Black Key Lock for Bikes

The lock works fine, but customer service is poor. Ordered replacement keys and I have been waiting almost 6 weeks for them so far. Called and was told a request to expedite would be put in two weeks ago and still no keys. Submitted an online service request 3 days ago and no response yet. I would not recommend purchasing if you think you might need replacement keys.

solid construction, easy to use

Someone tried drilling out the keyhole in the lock and gave up before they were successful. This $20 lock saved my sons $1500 bike! Since we weren’t able to use the key after they drilled we did have to pay a locksmith $200 to come remove it, but was happy to pay that vs losing an expensive bike.

I bought this lock because my U lock didn't work my other nijr was stolen. but they are not getting through this one it would take them awhile.

Defective.

Very sturdy. Easy to use

Excellent

This is nice for its simplicity and flexibility. Works great to attach one wheel and frame to parking structure. Easy to put in bag or basket when not being used.

super heavy duty

It's nice but you should mention it's best for big bikes and strong people and not kids or else just maybe home use cause it weighs a ton but good quality

The next time I'll just find it somewhere else, maybe another store so I can pick it up. The chain itself is really nice, but initially I was going to pick it up in the store, got an email that said it was no longer available but if I had it shipped I would get it the next day, so I selected that option and it automatically changes to the day after next. Okay....so the day after next comes still no chain, check online and it states there is a delay so I go to bed. It was delivered at 10:12p that night. The next time l'll cancel the order and find it somewhere else.

Bought this online and got a great deal! Definitely worth every penny!

Great lock, heavier than the bike 👍🏾

All likes no dislikes. This lock allows me to feel comfortable leaving my scooter or I should say my baby while I'm getting what needs to be done.🤩🤑🫠

awesome lock and chain

It was easy to use, but my scooter got stolen with this lock on so guess it doesn't work. The lock wasn't even broken or cut, it was picked.

Super easy to use. . Easy for my 10 yr to carry, lock and unlock . Comes with to keys.. great for scooters.

I will say that this lock is heavy. I didn’t expect it to be as heavy, but that’s a good thing when your trying to prevent theft. My youngest has a medical stroller/wheelchair (Cost 5k+) and we went to a theme park where your option is to leave your strollers. Wheelchairs, etc.. at the rides gates. Knowing we would be there 2 days and it would be unattended quite a bit I was very uncomfortable. A theme park staff suggested when I called the day prior to leaving to look at bike locks. Of course I’m instantly going to the Target app and I’m scrolling and find this beauty! It was ready same day which I love but I also loved that It was easy to unlock, easy to lock back, it didn’t scratch the metal on her Stroller. Plus thick and heavy remember?! To prevent theft! 😀 It’s wrapped around it as we speak because this was the absolute best pick I could’ve asked for for her stroller!!

This chain lock was easy to use and feels reasonably effective at keeping a bike locked up. The chain smoothly locks into place and is easy to unlock with the keys. I really like the size and weight of this chain. It's long enough to lock a frame and wheel to a stand and is not so long that it's excessively heavy or unwieldy. I prefer using this over U-Locks, which are less versatile. The protective sleeve covers the chain well and does a good job of preventing scratches. As one of Kryptonite's value-oriented offerings, this is not the thickest of chain locks, so I wouldn't expect this to hold up very long to an angle grinder compared to higher-end options. However, its budget nature lets this be relatively light for a chain lock. Great for keeping your bike light. It easily fits into my bike's 8L rack bag. I was able to register this on Kryptonite's website in case of needing a replacement key. It's under the Product Family 'N/A' and Model 'Kryptonite Key Chain'. I would recommend this lock to anyone who wants a light, budget-friendly, chain lock backed by a reputable brand.

It’s very durable, I like that it has a cloth over the chain to prevent scratching
