Reset Bike Lock Combo: 5 Best Resettable Combination Locks (2026)

Updated November 2026

Shoppers searching for a reset bike lock combo usually have one of two goals: they want to change the code on a lock they already own, or they want to buy a combination lock that lets them set a new code whenever they need to. This guide covers both. We compare five resettable combination locks on the criteria that matter most for everyday riding: security rating, lock type, length or reach, weather resistance and how easy the code is to change. Each pick is matched to a specific rider, so you can skip what does not fit your bike or your commute.

Our Top Picks

Before the comparison, a quick note on how these picks were chosen. The selection is based on published specifications, brand reputation for lock design, and patterns that owners commonly mention in their feedback, such as how a code feels when turning the dials, whether the cable or shackle stays flexible in cold weather, and whether the lock fits a standard frame tube. We have not physically tested these locks, so treat the notes below as a summary of what manufacturers specify and what owners tend to report.

Kryptonite Parkview Combo Bike U-Lock

Best for: Urban commuters who lock to a fixed post

This is a combination U-lock aimed at riders who want a sturdy shackle without carrying a key. It suits people who regularly leave a bike outside a shop, office or transit station for several hours and want a lock that resists common hand tools better than a thin cable.

Key specs

• 12mm steel shackle
• Resettable 4-digit combination
• Interior opening approximately 4 in x 8 in, per the listing

Pros

• Rigid U-shackle resists leverage better than most cable designs
• Combination can be reset without a key

• Bulkier to mount on a bike without a bracket

Bottom line: A strong choice for commuters who want a dependable U-lock and do not mind the extra weight. Riders who value portability more than security may prefer a lighter option.

Best for: Short stops and light, low-risk locking

This 6-foot vinyl-coated steel cable is a lightweight option for quick errands, such as a few minutes at a café or a library book drop. Owners often praise its flexibility and the simple resettable code, but cable locks are generally considered less secure than U-locks against cutting tools.

Pros

• Light and easy to carry in a bag or on the frame

• Resettable 4-digit combination
• Weather-resistant nylon sleeve

Pros

2 PACK Bike Locks Cable Combination Lock

Best for: Budget-minded riders and spare-lock needs

This two-pack of self-coiling cable locks is aimed at riders who want a second lock for a bag, a helmet or a backup location. The 2-foot length keeps it compact, but it limits the number of objects it can secure at once.

• Self-coiling design

Pros

• Two locks in one set

Buying Guide

Choosing a resettable combination lock depends on where you park, how long you leave the bike and what you need to secure. The factors below will help you narrow the field.

Lock Type: U-Lock, Chain or Cable

U-locks have a rigid shackle that is harder to pry or cut. Chains offer flexibility and can wrap around larger objects. Cables are lightest but easiest to cut with bolt cutters. Match the type to your risk level.

Resettable Combination Mechanism

Look for a lock where the combination can be changed by following the manufacturer’s reset procedure. Four-digit dials are common. Confirm the reset steps in the included instructions before you lock the bike for the first time.

Length and Reach

Measure the objects you need to secure, such as a rear wheel, a seatpost or a rack. A 6-foot cable will reach more than a 2-foot cable, but length also adds weight and bulk to carry.

Use Case and Vehicle Type

Electric bikes, scooters and motorcycles often need a heavier lock than a standard road bike. Check whether the lock is designed for your vehicle type, and confirm the shackle or chain diameter fits the parts you plan to lock.

Durability and Weather Resistance

Steel that is coated or sleeved resists rust and protects the finish. Check whether the lock is described as weather-resistant. Keep moving parts clean and dry to preserve the dial mechanism over time.

Security Level

No lock is theft-proof. A combination of a U-lock and a cable is a common approach for longer stops. Locking through the frame and wheel to a fixed object is generally more effective than securing only one part.

Budget and Spare-Lock Needs

A budget pick can still be useful as a secondary lock for a helmet, a bag or a low-risk stop. Avoid relying on a light cable as the only protection for a valuable bike.

FAQ

How do I reset a combination bike lock?

Most resettable combination locks have a reset procedure in the included instructions. Typically you enter the current code, then press or hold a reset button or sequence to set a new one. Follow the exact steps for your model, and test the new code before leaving the bike.

What if I forget my bike lock combination?

If you forget the code, check the original packaging or manual for a default or reset method. If the lock cannot be reset, a locksmith or the manufacturer may be able to help. Consult a professional locksmith if you are unsure how to proceed without damaging the lock.

Is a combination lock as secure as a key lock?

Security depends more on lock type and build quality than on whether it uses a key or a code. Combination locks remove the risk of losing a key, but they can be less convenient if you forget the code. Choose based on lock design and your parking situation.

Can I use a cable lock to secure an e-bike?

A cable lock can be used for short stops, but it is generally not recommended as the only lock for an e-bike, since cables can be cut more easily than U-locks or heavy chains. Many riders combine a cable for accessories with a stronger lock for the frame.

How often should I change the combination?

There is no universal schedule. Consider changing the code if you have shared it, if you suspect someone has seen you enter it, or if you have become tired of the old one. Use a code that is not tied to your birthday or address.

Do resettable locks wear out over time?

Dial mechanisms can wear with heavy use and exposure to dirt and moisture. Keeping the lock clean and dry, and avoiding forceful turning, helps extend its life. Check the manufacturer’s care guidance for your model.

Conclusion

For most commuters, the Kryptonite Parkview Combo Bike U-Lock is the most balanced pick because its rigid shackle and resettable code cover daily urban parking. Riders with heavier vehicles should look at the Kryptonite Keeper 712 chain or the NDakter U-lock. The Master Lock 8122D cable and the 2 PACK cable set suit short stops and secondary locking. Match your choice to where you park and how long you leave the bike, and always confirm the reset steps before relying on a new code.
