Here's a scene I've described to buyers more times than I can count, because they never see it themselves.
A US screener has a flagged bag in front of them. The inspection table is loud, the line is long, and the decision happens in seconds. The screener looks at the lock. Red diamond? Master tool, open, inspect, re-lock — the case continues its trip intact. No diamond? The lock gets cut. That's not malice. That's physics: inspection is the job, and an unopenable lock is an obstacle.
The decision is made at that table, based on the red diamond. Which is why TSA recognition is a design decision for US-bound luggage, made at the factory — not a problem the traveller discovers at the airport with a ruined lock in their hand.
What Happens at the Inspection Table
The screener's job is inspection, not destruction. When a bag is flagged, the sequence runs like this:
- The screener identifies the lock type.
- If the lock carries Travel Sentry recognition, the master tool opens it without damage.
- The bag is inspected and re-locked with the same lock.
- If the lock cannot be opened with recognized tools, the case is opened by force — the lock is cut.
The traveller's only control over this sequence is the lock they chose. That's why the choice matters before the trip, not during it.
The Cost of a Non-Recognized Lock
A cut lock is a small loss. The bigger cost is what follows:
- The case can no longer be locked for the rest of the trip.
- Contents may shift or be exposed.
- The traveller's trust in the product is gone.
- The review that follows is the brand's problem, not the screener's.
For a luggage brand, every cut lock is a negative review waiting to happen. That's why approved locks are the baseline for US-bound products, not a nice-to-have you negotiate later.
When we brief a US-market program, the lock spec gets decided in the same meeting as the shell material: TSA-recognized mechanism, approved model, and the license that authorizes the marks. A lock chosen later — "just put a lock on it" — is how cut locks happen, and how reviews get written.
What Screeners Recognize
The recognition is visual and binary: the red Travel Sentry diamond. It tells the screener the lock has the secondary override the master tools can operate. No diamond, no override — and the risk of cutting returns. The diamond is not branding. It's the interface between the product and the security system.
What Buyers Should Specify
- TSA-recognized mechanism — the lock must have the approved override.
- Approved lock model — confirm the specific model carries approval.
- Manufacturer license — the factory is licensed (CLK: LGM:20704).
- Marks applied correctly — the red diamond per Travel Sentry's rules.
- Year-current license — the license covers the production year.
Frequently Asked Questions
Why do TSA screeners cut some locks?
Because they cannot open locks without the recognized override. A lock the master tool cannot open is opened by force — the screener has no alternative for inspection.
Does the red diamond guarantee my lock is not cut?
It signals the override exists, so the screener can open it with the master tool instead of cutting. That is the purpose of the Travel Sentry system.
Can a non-TSA lock be used on US-bound luggage?
It can be used, but it carries the risk of being cut during inspection. For a brand, that risk is a review liability.
Who decides which locks are recognized?
Travel Sentry manages the approval program; TSA and other recognized agencies hold and use the master tools.
Is the lock decision really made at the factory?
For a brand, yes — the lock type is a spec decision made before production. The screener's choice at the table is already decided by that spec.
How do I confirm the lock on my product is approved?
Ask the factory for the approved lock model and the current Travel Sentry license, then verify through industry@travelsentry.org.

What happens at the inspection table
| Step | What the screener does |
|---|---|
| 1 | the screener identifies the lock type |
| 2 | if the lock carries Travel Sentry recognition, the master tool opens it without damage |
| 3 | the bag is inspected and re-locked with the same lock, and the case continues its trip intact |
| 4 | if the lock cannot be opened with recognized tools, the case is opened by force — the lock is cut |
That sequence is not malice — it is physics: inspection is the job, and an unopenable lock is an obstacle. The traveller's only control over this is the lock they chose, which is why the choice matters before the trip, not during it.
The real cost of a non-recognized lock
| Cost | Why it lands on the brand |
|---|---|
| The case can no longer be locked for the rest of the trip | a cut lock is a small loss, but the traveller's trust in the product is gone with it |
| Contents may shift or be exposed | an unsecured case for the rest of the journey |
| The review that follows | it is the brand's problem, not the screener's — every cut lock is a negative review waiting to happen |
| The lock spec decided late | a lock chosen later — "just put a lock on it" — is how cut locks happen, and how reviews get written |
Recognition is visual and binary
| What the screener sees | What happens next |
|---|---|
| The red Travel Sentry diamond | it tells the screener the lock has the secondary override the master tools can operate, so the bag can be opened with the master tool instead of being cut |
| No diamond | no override — and the risk of cutting returns |
The diamond is not branding. It is the interface between the product and the security system, which is why TSA recognition is a design decision for US-bound luggage and gets made at the factory.
What buyers should specify
Short answer: every item on this list is a specification decision made before production, and none of them can be fixed once the goods are packed. Screeners work from master tools, so a lock the tool cannot open is opened by force — not as a punishment, but because there is no alternative for inspection. What prevents that is a mechanism carrying the recognised override, and the override belongs to a specific approved model rather than to a factory or to a brand. The licence is the other half: it is held by the manufacturer and it has to cover the production year, because an expired licence on current orders is a mismatch a buyer will find later. Specification also covers the mark itself: the red diamond has to be applied the way the programme requires, or the visual cue the screener looks for is missing. Write all five into the purchase specification, then verify them on the sample.
| Item to specify | What it means |
|---|---|
| TSA-recognized mechanism | the lock must have the approved override |
| Approved lock model | confirm the specific model carries approval |
| Manufacturer license | the factory is licensed (CLK: LGM:20704) |
| Marks applied correctly | the red diamond per Travel Sentry's rules |
| Year-current license | the license covers the production year |
When a US-market program is briefed, the lock spec belongs in the same meeting as the shell material: TSA-recognized mechanism, approved model, and the license that authorizes the marks.
