Kryptonite Keeper U-Lock with Advanced Security Features

The Kryptonite Keeper Standard U-Lock is a reliable and robust bike lock, offering a top-notch security experience. The 12mm hardened steel shackle with a double deadbolt anti-rotation design ensures that the lock resists bolt cutter attacks and twisting leverage attacks.

The disc-style cylinder with a center keyway is protected by a vinyl coating, making it pick and drill-resistant. Two stainless steel ergonomically designed keys are included, which help to reduce torque and prevent the keys from bending or breaking.

Kryptonite’s patented side-mount, snap-in bracket makes it easy to transport the lock. This lock is rated at a 5/10 on our security scale and is suitable for quick stops in metropolitan areas, a couple of hours in suburban areas, or all-day and overnight in rural areas.

The combination of these features and Kryptonite’s support programs makes this lock an excellent choice for protecting your valuable bike.

Kryptonite Chrome 5-S Disc Stock Lock

I recently got the chance to test out the Krypto 5-S Disc Lock by Kryptonite. It was definitely smaller than what I imagined, but it had a good amount of weight to it. The lock is bright yellow, which attracts attention and makes conversations with random people about motorcycle security more interesting.

The installation process was easy, and the key matched the one for my bike. I added the included orange safety reminder cable to my clutch handle, serving as an extra layer of security. As a deterrent, I think it’s a great addition to other safety measures I already implemented on my motorcycle.

After having my bike secured with the Krypto 5-S Disc Lock, I can say that it hasn’t been stolen yet. It’s a sturdy and compact lock that can withstand different weather conditions. The lock’s design may not stop someone who’s set on stealing the bike, but its bright color and the reminder cable serve as an effective deterrent.

But, enough about appearances. This lock means business. I was impressed with the dual stainless steel ball-bearings that help prevent pry attacks, making it more than just an ordinary padlock. The 6 pin cylinder doesn’t shy away from being ASTM Security Grade 4, adding an extra layer of protection.

However, one downside I found was that it can be a bit of a hassle to remove the cylinder to key alike or re-key. Just a minor inconvenience compared to its overall robustness.

The high-security disc-style cylinder was pick and drill resistant, and the two stainless steel keys with ergonomic designs made it easy to unlock without any concerns about them bending or breaking. The new dust cover and weatherproof vinyl cover added to the protection and durability of the lock.

One of the biggest pros is the ease in which replacing the cores comes - making this perfect for my active lifestyle. However, one con I found is the price.
