HardWire Bicycle Key Cable Bike Lock

This lock is great. I bought a new generator for my travel trailer and used this lock to secure it to the frame. I didn't have to worry about someone walking off with it. Kryptonite was a key replacement program so that you can register your keys and if you lose them they will replace them for free the first time that you lose or misplace them.

UPDATE: After two months of use, the lock mechanism now works much smoother. If one can be patient during the "break-in" period, the lock works great.I read many reviews of Kryptonite key locks and I was skeptical about those that complained of sticking keys. Well, count me in as one that says that these locks suck. I've had this lock for a few weeks and today was the day that my lock almost would not unlock. I had put lubricant in it last week, but it quickly became sticky. Trust me, the key function in this lock is poor. I wanted this to be a good lock, but it will be difficult for me to use this lock if I must apply graphite grease every week. Save yourself the headache that I have and find something else. I am so disappointed.

The lock is very difficult to unlock. Worked fine the first three times. The last time, before I returned it to Amazon (thanks again for your great return policy), it took me 5 minutes fiddling around trying to getting the key to go all the way into the lock so it would work. The directions say not to "force" the key. Well, the only way I could get the key all the way into the lock was to force it. Too bad: I have three other, much older Kryptonite key cables with different locking mechanisms than this one and they have worked fine for years.

I have trouble getting it unlocked.It also is like trying to handle a python.Heavy and it doesn’t like to be uncoiled.I bought a less expensive one; I don’t use this anymore.

Keys work perfectly. EZ lock and un-lock. Key mechanism has a mechanical dust cover to prevent dirt and water from fouling the lock. Just be sure there's not tension or pulling on the ends when turning keys. As a bonus, write down the key numbers and the manufacturer will send a duplicate key if you loose the originals.

After my spare tire was stolen from underneath my SUV I used this cable to secure the replacement. Because I live in Chicago and Michigan I wrapped a decent amount of duct tape around the keyhole and the surrounding shroud with the hope that this would keep salt and other road dirt out - it didn't. Salt (or something) built up in the keyhole preventing me from inserting the key. I tried lubricating grease but it did not do anything for what had built up in the keyhole. I subsequently cut the cable using 24" Home Depot bolt cutters. I completely cut through the cable after 3 full squeezes of the bolt cutters.My application was probably not standard for this lock so take what you will from my experience...

I use this cable to lock my wife's and mine e-bikes. Extremely stout devise, takes a bit of effort to manipulate it around the bikes and through racks. Not very light but worth the protection it affords you.

It's heavy, somewhat inflexible and the lock didn't work until after it was thoroughly lubed with Dupont PTFE. Had to jiggle the key quite a while to work the lube into the mechanism, but eventually it freed up and now works as smooth as silk. For my purpose this cable lock works as expected and I recommend it. The product could be improved with the addition of a cap or cover to keep crap out of the locking mechanism - but a plastic sandwich bag and rubber band work as well.
