The Kryptonite Parkview Combo U-Lock is a 12mm hardened steel, keyless combination lock that secures bikes and gear with a resettable 4-digit code and standard 4" x 8" clearance.

If you need a no-key, no-fuss security solution for everyday lock-ups, this Kryptonite U-lock balances protection, portability and convenience. Its 12mm hardened steel shackle resists casual attacks while the resettable 4-digit combination eliminates the hassle of carrying keys. The lock’s dimensions and weight make it useful for a wide range of scenarios, from commuting to securing outdoor equipment at home.

How secure is the 12mm hardened steel shackle?

The shackle is made from tempered, hardened steel engineered to resist cutting and leverage attacks common in street theft. While no lock is invincible against determined, professional thieves with heavy tools, this U-lock raises the effort and time required to compromise your bike. It’s designed to be a strong deterrent for opportunistic thefts.

• 12mm hardened steel shackle improves cut resistance
• Compact U-shape reduces leverage points for pry attacks
• Solid crossbar and locking mechanism engineered for everyday use

How easy is the combination mechanism to use and reset?

The Parkview uses a four-digit, resettable combination, so you never need to carry a key. Setting or changing the code is straightforward and user-friendly, designed for riders who prefer keyless convenience. Kryptonite also offers a registration program to help recover a forgotten combination.

• 4-digit resettable code: simple to program
• No keys to lose—reduces one common point of failure
• Combo Safe Program registration assists if you forget your code

Will the size fit my bike and typical locking spots?

This U-lock is a standard size with 4" x 8" internal clearance, a common fit for many frames and racks. The external dimensions are compact enough to carry without bulky mounts yet large enough to secure frames, wheels, or multiple items to fixed objects. If you regularly lock larger frames or unusual configurations, measure your bike and rack before buying.

• Internal clearance: approximately 4" x 8" for frame and wheel fit
• External footprint: roughly 6.5" x 9.5" for transport planning
• Good fit for most commuter bikes, city racks and anchored posts

What extras and protections come with the lock?

Along with the physical lock, Kryptonite provides customer-focused services including an optional anti-theft offer and a lifetime limited warranty. Registering your combination enrolls you in the Combo Safe Program, which can help if you misplace your code. Customer support is available to address product issues.

• Optional $500 Anti-Theft Protection offer (registration required)
• Combo Safe Program for code recovery assistance
• Limited lifetime warranty and customer service support

Who is this for? The Kryptonite Parkview Combo U-Lock suits city commuters, students and homeowners who want a dependable, keyless lock for everyday use. It’s a practical choice for riders who value ease of use and solid theft resistance without carrying keys, and for anyone securing tools, gates, or outdoor equipment where a compact, strong U-lock will do the job.
