I used to skip the luggage lock. My reasoning was thin: the bag would probably be fine, the TSA could cut it open anyway, and it was one more thing to remember. Then I came home from a weekend trip to find my suitcase zipper had clearly been unzipped and re-zipped by someone who was not a TSA agent. Nothing was missing, but the feeling stuck with me. That was the last trip I flew without a lock on every checked bag.
The Forge TSA-approved combination lock is the one I settled on after trying a few others. Four locks in a pack, zinc alloy body, easy-read dials, a built-in open-alert indicator, and a 4.6-star rating across more than 13,000 reviews. It is not complicated gear, but it does a specific job well. Here are the ten reasons I think it belongs on every suitcase you ever check.
Your bag is going into a system you cannot watch. A lock costs less than your flight snacks.
The Forge 4-pack gives you enough locks for multiple bags and trips. Rated 4.6 stars by more than 13,000 travelers.

Most baggage theft is opportunistic. Someone with quick hands and thirty seconds of unsupervised access can unzip a bag and rifle through it faster than you'd believe. A combination lock does not have to be impenetrable; it just has to be slower than the next unlocked bag. Casual thieves skip locked bags. That alone makes the Forge lock worth every penny before you even get to the airport.
TSA Can Still Open It Without Destroying It
A regular padlock on your zipper means TSA will cut it off or slice your bag open if they need to inspect it. A TSA-approved lock like the Forge uses a recognized master key system, so agents can open it cleanly, relock it, and send it on its way. Your bag arrives intact. This is the key distinction between a TSA-approved lock and any random lock from a hardware store.
The Open-Alert Indicator Tells You If TSA Inspected Your Bag
The Forge lock has a small indicator that triggers when the TSA master key is used to open it. After your bag arrives, a quick glance tells you whether the lock was opened in transit. Most budget locks skip this feature entirely. Knowing that your bag was inspected, or was not, gives you real information instead of a guessing game about why your clothes are rearranged.
It Keeps Zippers From Migrating During Baggage Handling
Checked bags get thrown, stacked, and dragged. Unzipped zipper pulls can catch on conveyor edges or other bags and travel sideways, opening a gap in your bag. A lock pins the zipper pulls together so they cannot separate even under rough handling. I have had unlocked bags arrive with their zipper pulls pulled apart halfway around the bag. Never once with a locked suitcase.
A lock does not have to be impenetrable. It just has to be slower than the next unlocked bag on the belt.
The Zinc Alloy Body Holds Up to Real Travel Abuse
Plastic-body combination locks crack when bags are dropped hard or stacked under heavy luggage. The Forge uses a zinc alloy housing, which is the same material used in quality padlocks, not a toy-grade shell. I have had mine scratched, dragged across concrete, and returned from a notably aggressive baggage system in South America without any cracks or dial stiffness. It is genuinely built to last.
Easy-Read Dials Mean You Can Reset Your Combo in Two Minutes
Some combination locks have dials so small or stiff that resetting the combination feels like a punishment. The Forge dials are large, clearly numbered, and reset with a straightforward process that takes about ninety seconds. If you share bags with a travel partner or want to change codes between trips, it is not a project. This sounds minor until you are standing in a hotel lobby trying to reset a lock with luggage-tag hands.
A 4-Pack Means Every Bag on Every Trip Is Covered
One lock protects one bag. If you travel with a partner, or you check two bags, or you want a spare, buying singles adds up fast. The Forge 4-pack covers you for a family trip, a multi-bag itinerary, and a spare to keep in your gear drawer. The per-lock cost in a 4-pack drops significantly compared to buying individual locks from competing brands, and you always have one when you need it.
It Works on More Than Suitcases
The Forge lock fits the zipper pulls on checked bags, but the shackle size also works on soft-shell duffel bags, gym bags used as checked luggage, and tool cases if you are traveling with equipment. I have used mine on a camera gear pelican-style case and on a duffel for a sailing trip where the bag was going into a cargo hold without any oversight at all. One lock type, multiple use cases.
It Removes the Mental Load of Worrying About Your Bag
Part of the value of a luggage lock is psychological, and that is not a knock on it. When I know my bags are locked, I stop thinking about my bags. I am not scanning the baggage carousel already bracing for something to be wrong. That mental overhead, the low-grade wondering whether your bag is okay, disappears when you have a lock on it. Better travel starts before you board the plane.
It Costs Less Than Replacing a Single Stolen Item
The Forge 4-pack is priced well under most single items a thief would take from an unlocked bag. One stolen travel adapter, a pair of earbuds, a camera cable, a prescription bottle. Any one of those exceeds what four locks cost. The math is not complicated. If a lock prevents even one theft across the life of the pack, it has paid for itself with room to spare. And it will last many more trips than that.
What I'd Skip
If you are carrying on only and your bag never leaves your hands or overhead bin, a luggage lock is genuinely unnecessary. Carry-on bags sit above you or between your legs; the security threat is minimal and TSA is not opening overhead bins. The Forge lock earns its keep specifically on checked luggage. For a carry-on-only traveler, save the space and skip it. But the moment a bag leaves your hands at the ticket counter, a lock belongs on it. Full stop. If you want to go deeper on the full luggage security process, the guide on how to secure your luggage before every flight covers everything from locks to tracking tags.

I have also used the Forge locks alongside luggage tracking tiles, and the two work well together. The lock deters the immediate grab; the tracker helps locate a bag that gets lost or misrouted. For a full look at the lock's performance over multiple real trips, the Forge TSA luggage lock long-term review goes into the open-alert feature in much more detail and covers the specific trips where it triggered.
Four locks, one pack, every bag covered from here forward.
