How It Works - Look for the Red Diamond
1.The Red Diamond on Travel Sentry® Approved locks alerts the TSA and other airport security agencies that they can open this lock without destroying it.
2. Each lock has a special code, which is used by the TSA and other security agencies to know which tool to use to open the lock.
3. Every security screening location at all US airports and now many other international airports are able to open the lock and then relock it after inspection.
