In light of heightened security measures, if you fly to the USA, customs officers have the right to break your padlock in order to search your luggage. Under the TRAVEL SENTRY scheme, if you use a TRAVEL SENTRY lock, the customs officers will use their TRAVEL SENTRY master key to open your padlock if they feel the need to search your luggage. After searching your luggage they will relock your padlock ensuring the safety and security of your belongings. Always recommend a TRAVEL SENTRY lock when flying to the USA.
