You’ll often see them described as mini padlocks, small keyed padlocks, or simply luggage/diary locks. On our site, product titles may also list the body size (for example, 20mm, 22mm, 30mm, or 32mm), which helps indicate a compact lock.

• Mini padlock: A general term for small, lightweight padlocks.
• Luggage/diary lock: Small locks commonly used on zippers, bags, and journals.
• Keyed mini padlock: A compact lock that opens with a key (often includes 2 keys).

These are popular for backpacks, gym lockers, toolboxes, jewelry boxes, and travel. Names can vary by seller, so checking size and shackle fit can help you pick the right one.

You can browse small locks in our Padlocks and Locker Locks categories on Walmart.com. You’ll see compact options for luggage, gym lockers, cabinets, and more, including multi-packs and keyed-alike sets.

• Search tips: Try terms like “mini padlock,” “small lock with keys,” or sizes like “22mm” or “30mm.”
• Categories: Padlocks, Locker Locks, and related Home Security pages feature many compact choices.
• Convenience: Depending on your location, delivery and pickup options may be available.

Product pages typically list shackle size, body width, and what they’re best for (like travel or lockers), which can help you narrow down the right small lock.

Here are four small lock types you’ll commonly find on our site, each with different benefits:

• Keyed mini padlocks: Traditional compact locks that include keys; convenient for bags, toolboxes, and lockers.
• Resettable combination locks: 3–4 digit combos; no key to carry, useful for school or gym.
• TSA travel locks: Designed for air travel screening; helpful for suitcases and carry-ons.
• Fingerprint padlocks (often with key backup): Quick access with a fingerprint; some include a key as a secondary way to open.

The best choice depends on how you’ll use it, preferred access method, and the shackle size that fits your zipper or hasp.

Small padlocks come in several styles. Here are seven you’ll see in our selection:

• Solid brass mini padlocks: Compact and versatile for cases and cabinets.
• Hardened-shackle mini padlocks: Small size with a tougher shackle for added resilience.
• Keyed-alike packs: Multiple small locks that open with the same key—handy for sets of bags.
• Resettable combination minis: No keys; 3–4 digit dials for lockers or gym.
• TSA-approved travel padlocks: Suitable for luggage during air travel screening.
• Cable-shackle padlocks: Flexible cable fits unusual zipper pulls or latches.
• Decorative mini padlocks: Fun shapes or colors for diaries, gift boxes, or light-duty uses.

Always check size and shackle clearance to ensure a proper fit.

Choosing size is mostly about shackle fit and body width. A quick check can help:

1. Measure the opening: Note the diameter of the zipper hole or hasp slot to ensure the shackle isn’t too thick.
2. Check shackle clearance: Make sure the shackle height/width will pass through and close comfortably.
3. Match body size: For zippers and diaries, smaller bodies (often around 20–30mm) are common; larger lockers may need slightly bigger bodies.
4. Consider use and environment: For travel or outdoor use, look for sturdier materials or weather-friendly designs.

These steps can help you narrow options, but exact fit depends on your item’s hardware.
