🔓 Lock picks

Lock picks are not on the TSA's prohibited items list, so the screener may allow them through at their discretion or may choose to remove them if they believe they pose a risk. It's not unusual for lock picks to pass through without comment at US airports, but you may be asked to explain their purpose. The outcome can vary by officer and by airport.

Rules vary significantly outside the US. In some countries lock picks occupy a legal grey area — possession itself may be illegal depending on the jurisdiction, independent of any aviation rule. If you're flying internationally, research the laws of your destination country and any layover locations before packing lock picks in carry-on or checked baggage.

Because lock picks aren't officially prohibited in the US, screeners who flag them will usually make a judgment call based on context. Calmly explaining that you're a locksmith, security researcher, or hobbyist is reasonable, and having business cards or credentials may help. At the end of the day, the final decision rests with the officer, so be cooperative and don't argue if they decide to remove them.

In the US, carry-on is technically permitted under TSA rules, but given the discretionary nature of the decision, checking them removes the uncertainty at security. More importantly, check the laws of your destination — in several US states and many countries, simply possessing lock picks without a locksmith license is a criminal offense, so the bag they're in may matter less than whether you should bring them at all.
