You locked your suitcase? Cute. TSA has a master key for most locks. But if you use a non-TSA approved lock, they cut it off. No mercy.
That little red keyhole on padlocks? That’s the TSA’s secret handshake. They open it, inspect your stuff, then lock it back up. Unless they find something—then they leave a friendly Notice of Inspection inside.
That notice is a little yellow slip. It says, “We looked at your underpants. Have a nice flight.” It’s weirdly polite.
What About Your Electronics?
Your laptop and tablet get special treatment. TSA assumes they could be hollowed out and filled with bad stuff. So the X-ray looks for empty cavities or extra batteries.
A Kindle? They treat it like a potential hideout. A Nintendo Switch? They zoom in on the vents. Yes, they really do that. One officer said they once found a bag full of charging cables that looked suspicious. It was just a very organized traveler.
