Master Lock 4683Q Brass Keyed TSA Luggage Locks 4 Pack Review (2026)

Who this four lock set is built for

The 4683Q is aimed at families, roommates or solo travelers checking multiple bags who want the same key to open every lock. Because the four locks are keyed alike, one parent or group leader can carry a single key and open a partner's suitcase, a child's backpack and a shared duffel without juggling separate codes or keys for each. That makes it a better fit for group or family travel than a single traveler managing one bag, where a combination lock like Master Lock's own 4688D avoids carrying a key at all. It also suits anyone who finds spinning combination dials slow or fiddly, since a key turn is faster once you have it in hand, at the cost of needing to keep that key somewhere safe.

Body, shackle and the keyed alike system explained

Each lock in the set has a 7/8 inch, 22 millimeter wide solid metal body finished in brass and nickel, with a steel shackle about 3/32 inch, 2 millimeters in diameter and 7/16 inch, 11 millimeters long. That is a shorter, more rigid shackle than the flexible cable used on Master Lock's combination models, so it suits standard zipper pulls and hasp loops rather than tight or irregular openings. The keyed alike design means a single key profile opens all four locks in the package, and the set ships with two keys rather than one per lock, so a spare can be kept separately from the primary key. Like Master Lock's other travel locks, the 4683Q is recognized as TSA accepted in 29 countries, letting screeners open, inspect and relock bags without cutting the shackle.

Living with four locks and one key on the road

In practice, the appeal of this set is reducing four access codes to one physical key, but that convenience shifts the risk from forgetting a combination to losing that key. Packing the second key in a different bag, pocket or travel companion's luggage is the practical safeguard, since misplacing both keys mid trip leaves every locked bag inaccessible without cutting the shackle. The small keys and correspondingly small locks are easy to lose track of in a hostel locker or a jacket pocket, so a keyring or a dedicated pouch helps more with this set than with a combination lock. Brass and nickel construction resists surface rust better than plain painted steel, which matters for a lock that may sit in a damp backpack pocket or a checked bag exposed to weather on the tarmac.

How it compares with Master Lock's combination locks

Against the 4688D combination lock, the 4683Q trades a slightly stiffer, shorter shackle for the speed of a key turn, and a group of four locks for the price of covering an entire family's luggage rather than one bag. The 4696T two pack sits in between, using a longer, rigid extended reach shackle meant for equipment cases rather than the short shackle here. For a solo one bag traveler, a single combination lock is usually simpler since there is no key to protect, but for anyone locking more than two bags at once, buying four separate combination locks and memorizing four codes is more cumbersome than sharing one key across four keyed alike locks.

Verdict and who should choose differently

This set earns a score of 8.1 out of 10 in this guide, or a score of 7.8 out of 10 depending on where you look at the breakdown, driven mainly by strong value for covering multiple bags in one purchase. It fits travelers locking several pieces of luggage or gear bags who are comfortable managing a single key and a spare. Solo travelers with one bag, or anyone who has a history of losing small keys, will likely do better with a set your own combination lock such as the 4688D, since there is no physical key to misplace. Anyone who wants a longer shackle for equipment cases with an integrated hasp should also look at the 4696T instead, since its extended reach shackle is built for that shape rather than the shorter shackle used here.
