I bought two of these and the keys are interchangeable with this particular model. Which means if someone else owns this particular model of bike lock then they can use their key to open your lock and take your bike. Each bike lock should have unique individual locks so they won't be interchangeable.
I really like this Bicycle/Motorcycle lock because it is longer and wider than standard locks for the purpose, which allows me plenty of room to secure my frame and wheel at the same time. Also, I like the 4 keys that come with it so I don't have to fuss with finding one. Another nice feature is that you don't need the key to lock it in place, which I much prefer as the last lock I had needed a key to lock it and when a friend of mine borrowed my bike, he didn't know that just closing it would not lock it. As a result, the shank portion fell off while he was riding it back and he never noticed. This will fix that problem.
