All TSA luggage locks can be unlocked using a master key. The TSA officers have keys (a bunch of around 7 or 8 keys) that they can use to open millions of suitcases. Without the master key, you will need the combination code or the key that came if your lock. Your key is not a master key, it will only open your lock.

No, not "any" TSA key can open "any" TSA lock. There is actually a set of seven distinct master keys (labeled TSA001 through TSA007) that correspond to the different types of approved locks manufactured by various companies. If you look closely at the keyhole on a TSA-approved lock, you will see a small engraved code (e.g., "TSA007"). A TSA agent must select the specific master key that matches that code to open your bag. While these keys are strictly controlled and reserved for authorized security personnel, the "master key" designs were famously leaked online years ago, leading to 3D-printed versions becoming available in the "grey market." This means that while the system is designed to allow security to inspect bags without damaging them, it is widely considered a "convenience feature" rather than a high-security measure. For true security in 2026, many travelers use TSA locks for transit but switch to high-security non-TSA locks once they reach their hotel.
