The BetaLock™ is an aircraft-grade aluminum carabiner that can be locked with a key to deter theft. Use it to instantly connect, identify, or secure your gear. TSA approved.
Best For: Anyone who's left a bag unattended in a café, hostel, or train and hoped it'd still be there when they got back.
Carabiner speed when you need it - Spring gate clips on in half a second
Key-locked when you don't - Turn the key. The gate won't open. Not with fingers, not with tools.
Aircraft-grade aluminum - 7075-T6 alloy. The same stuff they build planes from
Stops grab-and-go theft - Deadbolt mechanism can't be squeezed or tugged open
Lighter than your keys - 55 g, fits in a palm
Two keys included - One to carry. One to stash at home
Pairs with the BetaLock™ Accessory Cable - secure lockers, helmets, or multiple zippers
*Available in 6 colours: Matte Black, Shadow Green, Canyon Orange, Gold, Metal, and Orchid.
Picture this: You're at a café in Lisbon. Your bag is on the next chair. You turn to order coffee. With a regular carabiner, someone squeezes the gate and your bag walks. With the BetaLock? They'd need your key.
Two modes. One piece of gear. - Gate open: it's a carabiner. Clip your bag to a chair, your bottle to your pack. Turn the key: it's a deadbolt. Done.
Not a padlock with a clip. - It's a carabiner with a lock built in. No dangling shackle, no combo to forget, no shape that screams "lock me first."
For travelers who don't want to think about it - Hostel dorms, train stations, café chairs, festival tents. Anywhere you'd normally leave a hand on your bag.
The old setup hurt - Cable lock the size of your forearm. Combination padlock with a pull-tab. Both look like loot. Both come off with a 30-second YouTube tutorial.
REAL QUESTIONS FROM REAL TRAVELERS
"Will this actually stop someone from opening it?" Yes. When locked, the gate is held by a steel deadbolt. You can't squeeze it, pry it, or tug it open. The only way in is the key.
"What if someone tries to cut it?" It's 7075-T6 aircraft aluminum — the same alloy they build airframes from. A determined thief with bolt cutters could get through, the same way they could with any portable lock. It's a deterrent against grab-and-go theft, not a vault.
"What if I lose the key?" You won't — Matador sends two with every BetaLock. Keep one on your keyring, one in your luggage. If you lose both, Matador's free repair program will help.
"Can I use it on a checked bag through TSA?" It's not TSA-approved (no master key). For checked-bag travel, use a TSA-approved padlock. For everything else — hostels, lockers, café chairs, day bags — this is the move.
"What if it breaks?" Matador repairs everything — in warranty or out. They fix it and send it back.
"How much does it actually weigh?" 55 g (1.9 oz). Less than a typical car key fob. You'll stop noticing it after day one.

Excellent locking carabiner—strong, lightweight, and easy to use.
I bought the betalock previously and i encountered some limitations when i used for the last overseas trip to lock my luggages using other type of cable. Finally, i ordered the betalock cables online and i found that it works well with my Betalock to secure my luggages in my next overseas trips. Thank you, Nitecore for this innovative products.
I am amazed with the Beta lock and it comes very useful with my office and travel backpack. It helps me to secure my backpack and other carry-on bags so that I will not lose them. I also see that it can be used to secure bicycles, camera, etc. Thank you very much for this innovative and useful products.
The perfect, versatile companion to the BetaLock. I ordered the BetaLock Accessory Cable to be used with the BetaLock that I purchased a while ago. I'm mostly using this combo to secure all of our luggage together at our travel destinations—and it works great! It seems pretty versatile though so I could also see us using it for locking up snowboards and other adventure gear. BONUS: The silicone storage loop is actually a pretty clever design, and helps keep the cord organized when it's not being used. Overall, very stoked on this simple little device. 10/10
Handy & Versatile Carabiner. This is my 2nd purchase. I have been using them for travel and especially international travel as a safety zipper lock with a key chain ring for my cross-body sling bag. They're very convenient to lock and to unlock. Last trip, I have used it as a hanger for my backpack on the back of the chair in front of me in a plane. It came in handy to reach for stuffs inside the backpack.
Repeat Purchase. Versatile and great for travel. Have used it as a safety lock on a zipper of a cross body sling bag. Found another use as a hanger on the back of the seat in a plane.
Added Layer of Confidence. I got this to secure my backpack in cafes, parks, and other places where I’d set down my bag next to me or on a seat at my table while eating or whatever. The Betalock gives me more confidence that my bag is safe from grab & go opportunists. Great product, Matador!
Cool and useful. It's really handy since you can use it as a regular Carabiner if it's unlocked, unlike most other locks where you have to use a key to open them each time. People also don't expect it to lock which is good for keeping items secure. It also looks like it would be harder to cut through than branded wire so that might help deter thieves. If I'm going somewhere crowded, I have a backpack that has locking zippers and metal running through the handle; I was able to lock it to a chair using the beta lock. Really happy I bought it.
Does what it needs to do while remaining stylish. I haven't gone to the full lengths of using this product yet, but I am certain that through the years I will find a way to utilize this in ways that will be most useful. The item feels very durable and has this build quality of longevity. Will update my review if anything comes up that's worth noting.
Fantastic. Hooked instantly. Fantastic. I didn't know there was a locking caribiner. I was hooked (see what I did there). Perfect for cycling and tethering up my helmet. Plus, in screaming orange to match out with iPhone17 Pro...killer!
