The 5 Best Luggage Locks
A luggage lock tells you more about access than it guarantees security. Soft zippers and fabric remain vulnerable, and a TSA-accepted lock can be opened during screening. I would decide whether I need an inspection indicator, a flexible cable for awkward zip pulls or several locks sharing one key. Those details change the purchase more than a generic 'TSA approved' label.
Forge is my first choice for two checked bags because its cable locks flag an opening. BV does a similar job at a lower offer. SURE LOCK gives one bag a four-digit code, while Master Lock's keyed four-pack suits a family that can keep track of the key. Its basic single cable lock is the inexpensive fallback.

01 — Forge
Best two-bag open alertForge Two-Pack Open-Alert Cable Locks
Forge puts two combination cable locks with open-alert indicators in one package. I would choose it for two bags when noticing a security inspection matters and a flexible cable helps reach narrow zipper pulls. A lock can signal opening, but it cannot make soft luggage theft-proof.
Forge leads for two checked bags when I want a cable to reach zipper pulls and an indicator that flags opening. The two-pack is more useful than buying single locks twice. BV below costs less for a similar brief; Forge earns first place through its stronger current review record, not a promise of theft prevention.

02 — BV
Best lower-cost alert pairBV Two-Pack Open-Alert Cable Locks
BV provides two three-digit cable locks with an indicator for inspection opening. I would pick it when two travelers need the same straightforward arrangement at a lower offer than Forge. Three digits are easier to set than four, but give fewer code combinations; the indicator still needs checking on arrival.
BV is my second pick for two bags when I want an inspection indicator but prefer its lower offer to Forge. The flexible cable helps with smaller zipper holes. I would choose Forge for the more strongly rated pair; BV also uses three digits, so code choice is narrower than on SURE LOCK.

03 — SURE LOCK
Best single four-digit lockSURE LOCK Four-Digit Open-Alert Lock
SURE LOCK uses a four-digit code and an inspection indicator in a single cable lock. I would choose it for one checked bag when an easy-read code is more useful than a two-pack. Only one bag is covered, and a stronger combination does not compensate for weak zippers or unattended luggage.
SURE LOCK moves to third for someone who checks just one bag and wants a four-digit code with visible inspection alert. I would pay for one rather than an unnecessary two-pack. It is not the best value for a family, and the extra digit does not make the suitcase itself secure.

04 — Master Lock
Best keyed family packMaster Lock Four-Pack Keyed-Alike Locks
Master Lock sells four keyed-alike TSA-accepted locks, useful when a family prefers one physical key for several bags. I would pick it over a combination pack only if keeping track of that key is easy. Lose it and the convenience disappears; these locks also lack the cable flexibility of the zip-pull options.
Master Lock gives a family four keyed-alike locks, so one key can open several bags. I would choose it only if the key has a reliable place in a carry-on. Losing that key is a worse failure than forgetting one combination, and the rigid shackle is less adaptable than the cable locks above.

05 — Master Lock
Best inexpensive single cableMaster Lock Three-Digit Cable Lock
This Master Lock is the lowest-cost single combination cable lock in the selection. I would use it when I need a basic visual deterrent for one suitcase and can live without an open-alert indicator. Its three-digit code and single-unit package are less compelling for several checked bags.
The basic Master Lock cable model finishes for someone who wants one low-cost three-digit lock and no extra features. I would use it as a modest visual deterrent, not as a security plan. The absence of an open-alert signal and single-lock package keep it below the more useful choices.

FAQ — Luggage Locks
01Does a TSA-accepted lock prevent luggage theft?+
No. It may deter casual opening and lets authorized screeners access a bag, but it cannot secure fabric, zippers or an unattended suitcase against theft.
02What does an open-alert indicator tell me?+
It signals that the lock has been opened. It does not explain who opened it or prove that contents are intact, so inspect the bag when you collect it.
The short answer
Start with the Forge Two-Pack Open-Alert Cable Locks.
I recommend it for two checked bags and opening alerts. Choose something else if you only need one simple lock.
