The short answer
Yes. The TSA allows lock picks in carry-on and checked bags.
Your picks, your tension tools and the wallet they live in can travel in the bag under the seat in front of you. There is a length limit, a few tools in a bigger kit that have to go in the hold, and one pick gun trap that catches people out every year. It is all below.
This is a US answer. The TSA runs screening at US airports and nowhere else. Other countries set their own screening rules, and so does the country you land in.
Seven inches is the line
The TSA rule for tools is a length rule. Tools 7 inches or shorter may go in your carry-on. Power tools, and any other tool longer than 7 inches, must be packed in checked baggage.
A pick set is nowhere near that limit. Hooks, rakes, diamonds, half-diamonds and every tension tool in a normal wallet sit comfortably inside it, case and all. The TSA's own entry for lock picks says the same thing in its own words, and adds one line worth reading: check with local law enforcement about traveling with the item.
What flies in the cabin and what goes in the hold
| What you are packing | Carry-on | Checked | Why |
|---|---|---|---|
| Lock picks, rakes and tension tools | Yes | Yes | Listed as allowed in both, and well inside the 7 inch limit |
| Pick wallets, cases and practice locks | Yes | Yes | Nothing on the prohibited list and nothing sharp to argue about |
| Anything longer than 7 inches, such as long reach tools | Hold | Yes | Over the carry-on length limit for tools |
| Electric pick guns | Hold | Yes | Power tools must be packed in checked baggage |
| A spare lithium battery for a pick gun | Yes | Cabin only | Spare lithium batteries are banned from checked luggage, so this one runs the opposite way to everything else |
| Crowbars and pry bars | Hold | Yes | Listed as checked baggage only, whatever the size |
| Drill bits and cylinder jigs | Hold | Yes | Listed as checked baggage only |
The pick gun trap
Your electric pick gun goes in the hold, because a power tool has to be checked. Its spare lithium battery has to stay with you in the cabin, because spare lithium batteries are banned from checked luggage.
Those two rules point in opposite directions, and the split has to happen at the check-in desk, not at the gate. If you are flying with an EPG, that is the one thing to get right.
On blades: the TSA bars multi-tools with a knife of any length from the cabin. None of our multitools carry a blade, so they screen as ordinary tools. If you are packing a pocket knife or a Leatherman alongside your picks, that is the item to move to the hold.
Pack them so they screen cleanly
- Keep the set flat in its wallet or case. A tidy row of picks reads as tools on the X-ray. A loose handful in a rucksack pocket reads as a puzzle, and puzzles get bags opened.
- Sheathe or wrap anything sharp in a checked bag. That is the TSA's own request, and it is there so nobody handling your case catches a tip. A zipped case or a leather wallet does the job.
- Put the set where you can reach it. If an officer wants a look, handing it over in five seconds is a very different conversation from unpacking half your bag onto the belt.
- Nothing loose in a pocket. Whatever you are carrying goes in a bag and through the scanner with everything else.
The officer at the checkpoint has the final call
Every one of these TSA listings closes with the same sentence: the final decision rests with the TSA officer on whether an item is allowed through the checkpoint. That is worth knowing before you travel with anything out of the ordinary.
The listing is what the officer is working from, so if you are asked, the whole conversation is usually three facts. They are lock picks, you pick locks as a hobby, and the TSA lists them as allowed in both bags. Be straight and be calm about it. Screening staff see far stranger things than a pick wallet.
Flying outside the US is a different question
The TSA rule stops at the US border. Other countries set their own screening rules and their own laws on carrying picks, and a connection counts, so changing planes in a third country brings that country's rules into play for the bag in the cabin with you.
Before an international trip, check the rules for your destination and for every airport you transit. If you cannot get a clear answer for a country on your route, the calm option is to leave the picks at home and get back to practice when you land back in the US.
Your own state's law still applies
Airport screening and state law are two separate questions, and clearing one does not answer the other. In most US states, owning lock picks for hobby, sport or trade use is legal. A few states treat possession differently, so it is worth knowing your own code before you carry a set across state lines. We cover that in full in our guide to picking locks.

Common questions
Can you bring lock picks on a plane?
Yes, on US flights. The TSA lists lock picks as allowed in carry-on and checked bags, and tools 7 inches or shorter may go in the cabin, which covers any normal pick set. The officer at the checkpoint always has the final call. Outside the US, other countries set their own rules.
Do lock picks have to go in checked luggage?
They do not. The TSA allows lock picks in carry-on bags. Checked is allowed too, and if you choose it, wrap or sheathe the picks so nobody handling the bag catches a tip.
Can you fly with an electric pick gun?
Yes, in your checked bag. An electric pick gun counts as a power tool, and power tools must be packed in checked baggage. Its spare lithium battery runs the other way and has to travel in the cabin with you, because spare lithium batteries are banned from checked luggage.
Will the TSA take my lock picks?
They should not on a US flight, because the TSA lists lock picks as allowed in both bags. The screening officer still has the final decision at the checkpoint, so keep the set tidy in its wallet, keep it easy to reach, and say plainly what it is if you are asked.
Can you fly internationally with lock picks?
That depends on where you are going and where you connect, and the TSA rule does not answer it. Other countries set their own screening rules and their own laws on carrying picks. Check the rules for your destination and for every airport you transit before you pack them.
Is it legal to own lock picks in the US?
In most US states, owning lock picks for hobby, sport or trade use is legal. A few states treat possession as evidence of intent, so check your own state's code. Picking locks you do not own or have permission to open is illegal almost everywhere.
