TSA Approved Cable Luggage Locks Re-settable Combination Review (2026)

Who this budget cable lock is built for

This lock targets travelers who want a cheap, functional TSA style lock for a backpack, suitcase or gym locker and are not looking for the build quality or brand recognition of a name like Master Lock. Because the combination is re-settable to a code you choose, it works the same way as pricier combination locks in daily use, so it suits anyone whose main goal is simply keeping zippers closed against casual tampering rather than serious theft. The low cost also makes it reasonable to buy several at once for multiple bags, or to treat one as expendable if it is confiscated, lost or left behind partway through a trip. It is a weaker fit for anyone locking valuables where the lock itself needs to resist a determined attempt to cut through it.

Materials, combination and TSA design explained

The listing for this lock is sold under the Forge brand, with a lock body described as zinc alloy and a cable made of tightly braided, sheathed steel with hardened steel ends at each side. The combination is re-settable using a lever style mechanism, commonly set or changed by flipping it with a pen rather than a dedicated tool, and it can be changed as many times as the owner likes rather than being fixed at purchase. Forge markets the lock as TSA approved with an added open alert feature, meant to show when a screener has opened the lock for inspection, and states that screeners must relock the cable after checking a bag rather than leaving it open. The cable style shackle threads through tight or oddly shaped openings, such as backpack zipper pulls, more easily than a rigid steel loop.

Using it day to day and what limits it

In practice, a thin steel cable lock like this one is best treated as a deterrent against opportunistic tampering rather than a serious security device, since a determined person with basic cutting tools can get through a cable faster than a hardened steel shackle. That makes it well suited to keeping a backpack's zippers closed on a train or in a hostel common area, where the goal is simply making casual access slower and more obvious, rather than to protecting a case full of valuables left unattended. Setting the combination is a quick, one time task, and because the cable flexes, it works on odd shaped openings that a rigid padlock shackle cannot reach around. Given the low price, losing or breaking one is a minor inconvenience rather than a costly mistake, which is part of the appeal for travelers who tend to misplace gear.

A branded lock, not an unbranded one, and how it compares

Amazon listings for this lock show it sold under the Forge name with a stated zinc alloy body and a TSA approved lock core, rather than being a fully anonymous, unbranded product, though it still lacks the decades of reputation that Master Lock carries. Against Master Lock's 4688D or 4696T, this lock is noticeably cheaper and uses a thinner cable rather than a solid metal shackle, trading cut resistance for price. Against Master Lock's keyed 4683Q four pack, this lock avoids needing a shared key at all, at the cost of a less proven combination mechanism and a body material that has not been independently tested here. For travelers who mainly want a working TSA style lock at the lowest reasonable price, that trade generally makes sense; for anyone locking a bag they cannot afford to have opened, it does not.

Verdict and who should spend more

With a score of 7.0 out of 10 in this guide, the lowest among the TSA locks compared here, this cable lock earns its spot mainly on value rather than on build quality or features. It suits travelers who want a cheap, re-settable lock for light duty use on a backpack or suitcase and are comfortable with a thinner cable instead of a solid steel shackle. Anyone who wants a lock from an established brand with a longer track record, a thicker shackle or a documented warranty should look at Master Lock's 4688D combination lock or 4683Q keyed four pack instead, both of which carry a higher score in this guide for build and specs even though they cost more than this budget option.
