Frequently Asked Questions

  • Can I lock two bikes with this?

    I've locked two bikes together with this before. It depends on what you're locking them to, but it's definitely possible.

  • Do the keys come with an ID to register on the Kryptonite website in case they are lost and need to be replaced?

    There is a way to register online with the lock and key. But you need to register within 10 days of purchase. I unfortunately didn't open my package and lock right away since I presently have my bike locked in a storage locker and probably missed out. There is a $10.00 charge to register for a year with a chance to extend it later.

  • Does the cable lock to the bar lovck

    Yes. You can use the u-bar lock to lock the cable to. Or you can have a separate lock to use with the cable.
    In short, they're two separate locks that can work in tandem or separately.
