Here is the rule that trips people up at the counter: TSA gun case locks should not be TSA-approved locks<\/strong>. A firearm in checked baggage has to ride in a locked, hard-sided container, and federal rules say only the passenger may keep the key or combination. So you want ordinary keyed or combination padlocks \u2014 one in every lock hole.<\/p>\n

That is the opposite of the advice you hear for the rest of your luggage. For a suitcase, a TSA master-key lock lets screeners open, inspect and re-lock the bag without cutting anything. For a firearm case, a lock a screener can open alone defeats the point, and a sharp agent will tell you so.<\/p>\n

If the firearm you are locking up is a shotgun, see our shotgun cases<\/a>: hard, lockable and sized by interior length.<\/p>\n

Do TSA gun case locks have to be TSA-approved?<\/h2>\n

No \u2014 the opposite. Federal regulations for transporting firearms in checked baggage require the firearm to be unloaded and carried in a locked hard-sided container, and the passenger must be the only person with the means to open it. A TSA master-key padlock can be opened by anyone holding that master key, so it fails the spirit \u2014 and in most airlines’ reading, the letter \u2014 of that requirement.<\/p>\n

What happens in practice: you declare the firearm at the ticket counter, fill out the declaration tag, and the case goes with you or with a TSA officer to a screening area. If screening needs the case opened, you are called back to open it yourself<\/strong>. That is why you stay near the checked-baggage area until your bag clears. Airlines publish their own waiting window; ask the agent how long theirs is.<\/p>\n

Keep the master-key locks for the gear that is not a firearm. A set of TSA-accepted 3-digit combination locks<\/a> is the right call on a camera case, a tool case or a clothing bag, where you would rather have a screener re-lock your case than cut the lock off. On the firearm case, they are the wrong tool.<\/p>\n

How many locks does a gun case need?<\/h2>\n

The honest answer: as many as your case has lock holes<\/strong>. The regulation says “locked,” not “one lock.” But airline agents are trained to look for a container that cannot be pried open at an unlocked corner, and an empty lock hole is exactly what they notice. A 49-inch rifle case with one padlock in the middle and nothing at the ends can be flexed open far enough to get a hand inside. That is a denied bag.<\/p>\n

Buy locks by the number of holes, not by the number of guns.<\/p>\n\n\n\n\n\n\n\n\n\n

Carry one spare lock in your carry-on. Locks get lost and keys snap off in cold weather, and a spare costs you nothing but a little space.<\/p>\n

What kind of lock actually passes at the counter?<\/h2>\n

Three things matter, in this order: it fits the hole, it closes fully, and only you can open it.<\/p>\n

\"Eylar<\/figure>\n

Shackle diameter vs. hasp hole.<\/strong> This is where most online lock purchases go wrong. Hard case<\/a> lock fittings are molded to a specific size \u2014 the Eylar\u00ae 49-inch tactical slim rifle case<\/a>, for example, has two quarter-inch padlock fittings, so you need padlocks with a shackle that passes cleanly through a quarter-inch opening. A thick 3\/8-inch shackle off the hardware store wall will not go through, and you will find that out at 5 a.m. Check the spec before you buy.<\/p>\n

Shackle clearance.<\/strong> The shackle also needs enough vertical room to clear both halves of the fitting and still click shut. Short-shackle “discus” style locks are tidy and hard to cut, but on some cases they bottom out. Test every lock on the actual case, loaded, at home.<\/p>\n

Keyed or combination?<\/strong> Both are legal. The trade-offs are real:<\/p>\n\n\n\n\n\n\n\n\n\n
Lock type<\/th>\nGood for a firearm case?<\/th>\nWatch out for<\/th>\n<\/tr>\n<\/thead>\n
Keyed padlock (non-TSA)<\/td>\nYes<\/td>\nKeys get lost; keep a spare key separate from the case, never inside the bag<\/td>\n<\/tr>\n
Combination padlock (non-TSA)<\/td>\nYes<\/td>\nSet all locks to the same code; dial numbers are hard to read in a dim bag well<\/td>\n<\/tr>\n
TSA master-key lock<\/td>\nNo<\/td>\nScreeners can open it \u2014 fails the “only the passenger” rule<\/td>\n<\/tr>\n
Cable lock through the handle<\/td>\nNo<\/td>\nDoes not secure the lid; the case still opens<\/td>\n<\/tr>\n
Zip ties \/ luggage straps<\/td>\nNo<\/td>\nNot a lock; cut in seconds<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

My preference for air travel is keyed padlocks, all keyed alike, with one key on my person and a spare in a carry-on pocket. At the counter you are tired, the line is moving, and turning four identical keys is faster than spinning four dials. If you fly with a partner who may need to open the case, combination locks win.<\/p>\n

Why do cable locks, zip ties and soft cases get turned away?<\/h2>\n

A “locked hard-sided container” has to resist being opened without the key. Three common failures:<\/p>\n
