TSA-Accepted Luggage Locks, Explained (2026)
A TSA-accepted lock is one that U.S. screening officers can open with a master key, inspect, and relock, so they may not have to cut it. Official TSA language names two systems — Travel Sentry and Safe Skies — and also says TSA has no position on these locks as a security measure and will still remove them if necessary. Look for the Travel Sentry Red Diamond (and a code such as TSA007) or the Safe Skies mark on the lock itself, not only on the box. This is not a theft-proofing guarantee, and we are not ranking a “best” lock we have not tested.

Quick answer
A TSA-accepted lock is one that U.S. screening officers can open with a master key, inspect, and relock, so they may not have to cut it. Official TSA language names two systems — Travel Sentry and Safe Skies — and also says TSA has no position on these locks as a security measure and will still remove them if necessary.

We compared official pages from the Transportation Security Administration, Travel Sentry (including a how-to article dated October 8, 2026), Safe Skies, and a U.S. Customs and Border Protection release dated February 24, 2025, all fetched November 10, 2026. We have not lab-tested locks, and we do not invent scores or a ranked product list. If a store calls a lock “TSA-approved,” check the mark on the lock and read TSA’s own wording: officers can still cut or remove it. Confirm the live packaging before you buy.
Built-in locks on many carry-ons use the same systems. For suitcase shopping, see best carry-on luggage, best checked luggage, and hardside vs softside luggage.
What TSA actually says about locks
On its official Security Screening page, under checked-baggage screening, TSA writes that it “has been provided universal ‘master’ keys under agreements with Safe Skies Luggage Locks and Travel Sentry so that certain branded locks may not have to be cut to inspect baggage.” The same paragraph says the packaging should indicate that TSA officers may open the lock, that “TSA has no position on the validity or effectiveness of these product as a security measure,” and that officers “will be forced to remove these products if necessary during the inspection.” If a bag is physically inspected, TSA says it will leave a notice of baggage inspection inside.
That is the official bar. A TSA-accepted lock is a screening convenience, not a TSA endorsement that the lock stops theft. Travel Sentry’s own official TSA-lock page makes a similar point: the locks are meant to let authorised officers inspect and relock a bag, and “no travel lock can guarantee total protection against determined theft.”
Safe Skies’ official homepage is more absolute in places (“your luggage lock will not be clipped”) and also says that in the rare event a Safe Skies lock is clipped, its lifetime warranty and hassle-free replacement policy will replace it. We report both the TSA wording and the Safe Skies wording; we do not flatten them.
Travel Sentry versus Safe Skies, and how to spot a real lock
| Travel Sentry | Safe Skies | |
|---|---|---|
| Named by TSA? | Yes, in the official Security Screening locks paragraph. | Yes, in the same TSA paragraph. |
| How to identify it, as written | Official pages: look for the Red Diamond on the lock itself, plus a short code near the keyhole such as TSA002 or TSA007, and a three-letter manufacturer code. Do not rely on the box alone. Travel Sentry warns that imitation locks may copy the look or print “TSA accepted” on packaging without meeting its standard, and that screeners’ tools will not open those locks. | Official homepage: “Recognized and Accepted by the United States Transportation Security Administration.” The pages we fetched did not isolate a single official logo name in the same way Travel Sentry names the Red Diamond; check the mark on the lock and the packaging claim against TSA’s “packaging should indicate they may be opened by TSA officers” language. |
| Where the system is used, as written | Official how-to page (October 8, 2026): founded in 2003; screeners at checkpoints in 850 airports in 80 countries are equipped with Travel Sentry tools. International use is “the best chance of keeping your lock intact, but it is not a guarantee at every airport worldwide.” A separate CBP release dated February 24, 2025 describes a formal partnership so CBP officers at U.S. ports of entry can open and relock Travel Sentry-compatible locks during customs inspections — that is a different agency from TSA airport screening. | Official homepage presents Safe Skies as “the luggage lock for the global traveler,” with a lifetime warranty and, it says, free shipping to all U.S. destinations. We did not fetch a comparable official airport-count figure for Safe Skies and are not inventing one. |
| Traveler key? | Official FAQ: combination TSA locks do not come with a key for the traveler. The keyhole is for airport security tools, not passengers. | The homepage fetch did not publish a traveler-key policy in the extract we captured; confirm the product page for the lock you buy. |
Travel Sentry’s October 8, 2026 how-to says combination locks usually start at a factory code of 0-0-0, and that if you forget the code there is no backup key for personal use — only about 1,000 three-digit possibilities to try. That is official reset advice, not a security review.
Who should skip this guide
- Shoppers who want a ranked “best lock” list with lab scores or a winning ASIN. We did not test locks and we do not guess Amazon ASINs. Official pages tell you to buy from licensed or established brands and to check the mark on the lock.
- Anyone who thinks a TSA-accepted lock makes a bag theft-proof. Official TSA and Travel Sentry pages do not support that claim.
- Travelers who only need a suitcase recommendation. Start with best carry-on luggage or best checked luggage; many of those cases include a built-in TSA-accepted lock.
- People comparing packing cubes or toiletry kits. See best packing cubes.

Travelpro vs Briggs & Riley (2026)
These are both official two-wheel, expandable 22-inch softside carry-ons, not spinner-to-spinner twins. Travelpro’s Platinum Elite Carry-On Rollaboard is $390, 7.7 lb and 53.5 L, with overall dimensions of 23 × 14.5 × 9 inches including wheels and handles — over United’s published 22 × 14 × 9 in box on height and width, though Travelpro says it is sizer-bin tested. Briggs & Riley’s Baseline Essential 22" is $679, 9.7 lb and 39–51 L, with official unexpanded exterior dimensions of 22 × 14 × 9 inches. The warranty split is sharper than the size split.
guideHardside vs Softside Luggage (2026)
On official pages fetched November 10, 2026, Away describes hardside as an impact-resistant polycarbonate shell starting at $275, softside as abrasion- and water-resistant nylon starting at $225, and aluminum as a premium hard shell starting at $625. Monos, which sells polycarbonate and aluminum cases, not a softside line on the pages we fetched, says its German Makrolon polycarbonate flexes under impact and springs back. We compared those written material claims and the conflicting official measurements, not a drop-test scorecard. Confirm dimensions, including wheels, in an airline sizer.
best ofThe Best Medium Checked Luggage
All three official overall sizes sit under United’s published 62 linear-inch checked limit. Travelpro’s Maxlite 5 Medium Check-In is much lighter and cheaper, with more listed volume. Away and Monos list at $345 and trade a few pounds and liters; the bigger split is what each included warranty covers if an airline mishandles the bag.
best ofThe Best Carry-On Luggage for Holiday Travel
If you need a bag that matches United’s published 9 × 14 × 22 in limit (wheels and handle included), Monos’ official Carry-On dimensions do. Travelpro’s Maxlite 5 is much lighter and cheaper, and Away’s The Carry-On sits slightly over that published box on two dimensions — confirm with a sizer.
best ofThe Best Packing Cubes for a Carry-On
If you want a four-piece set that stays organized without a separate compression zipper, Away’s Insider Packing Cubes are $48. If empty weight matters more, Eagle Creek’s Pack-It Isolate Cube Set (XS/S/M) lists $59 and 3.1 oz for the three cubes. If you actually want a compression zipper, get Eagle Creek’s Isolate Compression Cube M ($30) — Away’s official FAQ says its cubes do not have a separate compression zipper.
comparisonAway vs Monos Carry-On (2026)
Both list at $275. Monos publishes overall dimensions that match United’s 9 × 14 × 22 in box and is lighter. Away’s Size block is slightly larger, and its included LifetimeCare covers functional airline mishandling for five years — something Monos’ included warranty does not.
best ofTSA 3-1-1 Toiletry Kits and Travel Bottles, Explained (2026)
TSA’s official liquids rule is a quart-sized clear plastic zip-top bag, containers of 3.4 ounces (100 milliliters) or less, and one bag per passenger. A branded clear toiletry case is not automatically that bag. On official pages fetched November 10, 2026, Away’s Clear Toiletry Bag is $75 and 8.3 × 5.5 × 3.6 in — useful as a clear organizer, not a claimed quart 3-1-1 substitute. Matador’s FlatPak bottle is $15; the same page says both 3 fl oz (100 mL) and a 3 oz (90 mL) volume. Cadence’s Large Capsule is $38 and 2.75 fl oz, with a stated fit of four in a quart-sized bag.
