Kryptonite Keeper 510 Foldable Lock

The 360-degree rotation allows the links to move freely, making it much easier to maneuver the lock around awkward bike racks, poles, or street signs. It essentially gives you more flexibility to find a secure anchor point in tight or crowded spaces.

No, the lock comes with a protective neoprene cover that acts as a buffer between the hardened steel links and your bike's paint. This prevents the scuffs and scratches often caused by metal-on-metal contact.

The Keeper 510 is designed primarily for quick stops and short-term parking situations. If you regularly leave your bike unattended for long periods in high-theft areas, you may want to consider a heavier-duty U-lock or chain lock for added security.

The lock is designed to fold into a very compact, manageable shape. It is easy to stow away in a bag or mount to your bike frame, making it a convenient option for commuters who don't want a bulky lock rattling around while they ride.

The lock includes two keys, so it is best to keep one in a safe, accessible place at home. Because these are wafer-style keys, we recommend registering your key number with Kryptonite immediately after purchase to facilitate potential replacements.
