Product Overview
Sure Lock TSA Approved Combination Luggage Locks are the trusted choice of millions of travelers worldwide, offering a seamless blend of security, convenience, and smart design. As a licensed Travel Sentry distributor since 2013, Sure Lock has built its reputation on reliability, innovation, and customer trust—earning recognition as an Amazon No.1 Best Seller for over six years and being featured in major publications like MSN News and Star Tribune.
Each lock in this 4-pack set features a patented open alert indicator that instantly notifies you when your bag has been accessed during a TSA inspection. The red button visibly pops up when opened with a master key and remains visible until you enter your personal code to reset it. This gives you peace of mind knowing exactly what happened to your luggage—no guessing, no uncertainty.
Constructed from ultra-durable zinc alloy with a crush-resistant body and corrosion-resistant internal components, these locks are built to endure the rigors of airport handling. The included 4-inch flexible steel cable allows threading through zippers, handles, and tight spaces where rigid shackles can’t reach—making them ideal for suitcases, backpacks, gym bags, Pelican cases, tents, toolboxes, and more.
Why Choose Sure Lock?
Unlike traditional padlocks that require keys—and risk losing them—Sure Lock uses a fully customizable 3-digit combination system. With over 1,000 possible codes and a user-friendly reset mechanism, you control your security without relying on physical keys. Whether you’re a frequent flyer, outdoor adventurer, gym enthusiast, or someone who simply values smart protection, Sure Lock adapts to your lifestyle.
Large white numerals on matte black dials ensure effortless reading under any lighting condition, from bright terminals to dim hotel rooms. And because the design is intuitive, even first-time users can set or change their code quickly and confidently.
Key Features
- Travel Sentry Licensed & TSA Approved: Each lock displays the official Red Diamond logo and bears a unique code (TSA001–TSA008) recognized by U.S., Canadian, and international security agencies. Agents can open your luggage for inspection using approved tools—without damaging the lock or your belongings.
- Open Alert Indicator: A red button rises visibly when the lock is opened by TSA personnel. It stays raised until you unlock it with your personal code—giving you immediate confirmation of whether your bag was screened.
- Customizable 3-Digit Code: Set or change your combination anytime using the patented side window and reset switch. Default code is 000; over 1,000 unique combinations provide strong protection against unauthorized access.
- Durable Zinc Alloy Construction: Engineered to resist crushing, prying, and harsh handling, this robust material ensures long-term durability across years of travel.
- Flexible Braided Steel Cable: At 4 inches long, the coiled cable easily navigates tight zipper pulls, curved handles, and awkward bag shapes—offering versatile locking options beyond standard luggage.
- Large, Easy-Read Dials: High-contrast white digits on a non-reflective black background eliminate guesswork, even in low light or without glasses. Perfect for rushed mornings or crowded airports.

Versatile Applications
These locks aren’t just for suitcases—they’re built for real-world use. The flexible cable makes them perfect for securing backpacks during hiking trips, gym lockers after workouts, camping tents at night, duffel bags on road trips, computer satchels, briefcases, and even specialized gear like Pelican cases and gun safes. Wherever you carry valuable items, Sure Lock provides discreet, effective protection.
For travelers, the open alert feature is especially reassuring: after arriving at your destination, you’ll know immediately if your checked baggage underwent inspection—helping you spot potential tampering or missing contents.
How It Works
Setting up your lock is simple. Start by opening it using the default code 000. Then locate the small reset switch on the back of the lock (beneath the dials). Flip it right with a pen or paperclip to enable code changes. Rotate each dial to your desired 3-digit combination—such as 123—then flip the switch back left to lock in the new setting. That’s it.
To change the code again later, repeat the process using your current code. Remember to write down your new combination and store it securely—resetting doesn’t erase prior settings unless you manually change them.
Important Notes
- All locks ship pre-set to code 000—you must create your own code before first use.
- This listing includes four black locks only. Sure Lock offers other colors and sizes, but this pack is optimized for standard carry-on and checked luggage.
- While multiple models exist, this version features a universal size suitable for most zippers and handle types.
- Always record your final combination in a secure place separate from your luggage.
