Forge Dual-Opening Guardian Locks 6 Pack Review (2027)
The Forge Guardian six pack opens by code or by key, with the key recovering a forgotten code. Our research verdict on the forgiving lock.


Forge Dual-Opening Combination and Key Locks, 6 Pack
The forgetful traveller's insurance: open by code or by key, with the key able to recover a lost code.
Our verdict
The Guardian pack solves the one problem that makes combination locks stressful: the forgotten code. A key opens the lock and recovers the combination, so the classic airport disaster of a locked bag with a lost code simply does not happen, provided the key is kept safe. Six black locks cover a household, the stainless steel shackle feels solid, and the TSA006 system is the stated Travel Sentry standard for this model. The cost is key management: six locks mean keys that must live somewhere deliberate, not loose in a bag. For travellers who know they forget codes, that trade is worth it many times over.
What we like
- Dual opening: the lock opens with its combination or with its key, so a forgotten code is not a ruined trip
- The key can recover the combination, which removes the usual combination-lock dread
- Stainless steel shackle on a six-pack of black locks covers a whole household's luggage
- TSA006 key system, the Travel Sentry system stated for this model
What to watch out for
- Six locks mean six keys to keep track of, unless the household keeps one set in a known place
- The key is small and easy to lose inside a packed bag if it is not kept in a fixed pocket
- A shackle lock still needs zipper pulls with enough clearance for the loop
What owners report: Forge Dual-Opening Combination and Key Locks, 6 Pack
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Owners describe the key backup as the feature that finally let them relax about combination locks
- Families say six locks is the first pack size that actually covers every bag they own
- Travellers like that the black shackle locks look the same on every bag, with no colour confusion
Common complaints
- Some owners admit the spare keys ended up in a different bag from the lock they open
- A few find the shackle stiff to close until the lock has been used a few times
- Owners who only needed two locks say the six pack left four sitting in a drawer
Who it is for
Travellers who forget codes, and households that want a key backup on every bag they own.
Forgiveness is a feature, not a gimmick
Most lock features add security or convenience; this one removes fear. A traveller who knows a key can recover a code stops worrying about the code, which means the code gets set properly instead of being chosen as something trivially memorable. That second-order effect matters: a lock used without anxiety is a lock used correctly, and a lock used correctly is a lock that stays shut in transit.
Six locks is a household decision
Six locks sound like overbuying until a household counts its travelling bags: two checked bags, two carry-ons, a backpack and a gym bag, and the pack is used up. The uniform black finish means no colour debates, and the same key pattern across the pack means one key habit to learn. Households that travel with fewer bags will have spares, which is a better problem than a shortage at packing time.
The key habit to build
The Guardian's weakness is the same as every keyed lock's: a lost key. The fix is a permanent home for the key in the travel kit, a pocket that is always the key pocket, and a spare kept separately from the travelling set. Owners who build that habit report no problems; owners who toss the key into a random bag pocket rediscover the forgotten-code problem in key form.

Questions, answered
How does the key recover my code?
Opening the lock with its key lets the owner access the combination mechanism and recover the set code, per the maker. Keep the key safe and follow the maker's recovery steps, rather than forcing the lock.
Do all six locks use the same key?
The pack is sold as a matching set with keys for the locks in the pack. Test every lock with its key before travel, and keep a spare key in a separate, known place.
Is the Guardian a shackle or cable lock?
It is a shackle lock with a stainless steel shackle, so it needs zipper pulls with enough clearance for a rigid loop. For awkward pulls, the Forge cable pack is the sibling to pair with it.

- Checked bags face two threats a carry-on never meets: a screener who may need inside, and a conveyor system that tests every dangling part. This ranking therefore weights TSA acceptance first, then inspection indicators that report an opening, then a shackle or cable that will not snag. Carry-on-only locks with no inspection story do not belong here, even if they are well made.The Best Luggage Locks for Checked Bags (2027)
- Cable locks exist because shackle locks do not fit every bag. This ranking starts from fit: which pulls, loops and hasps the cable can thread, and whether the length joins one pull or two. Length is then judged as a trade-off, since a long cable that is not managed snags, while a short cable cannot join distant pulls. Indicators and opening type decide the order within each length class.The Best Cable Luggage Locks (2027)
- This ranking is for travellers who have decided that a pure combination lock is not for them, either because codes get forgotten or because keys feel simpler. Within that group, the split is between pure keyed locks, which are simplest but punish a lost key, and dual-opening locks, which forgive both a forgotten code and, with a spare key kept safe, a lost code. The ranking rewards forgiveness: the lock that leaves the fewest ways to be locked out of your own bag wins.The Best Keyed and Dual-Opening Luggage Locks (2027)
