10 Best TSA-Approved Luggage Locks UK 2023 | Anvil, Master Lock and More

With a name like 'Anvil', you just know your luggage is in strong and capable hands. The only locks on the list with four-digit dials, Anvil have ensured good odds on your luggage arriving as it should with no chance of tampering. 

Featuring a hardened and durable zinc alloy body as well as a thickened steel shackle, you can travel easy knowing your cases are locked with the best. We believe that this handy pair is worth every penny and absolutely the smartest TSA-approved option while in transit. 

If you're after a traditional padlock design with very good security, we recommend this pair from the affirmable Master Lock. This reassurance is achieved through a miniature clearance of 1.3 cm for the shackle, making it absurdly hard to cut through. 

Being locked by keys instead of a combination also gets shot of any would-be thieves who fancy their combination-code-breaking skills. Small in size but big in design, with this particular pair, Master Lock have stopped at nothing to protect your luggage. 

Hitting every mark in terms of design and construction, Sure Lock's Travel Sentry lock could well be the answer to your luggage locking woes. Using a cable design means that the lock is ready to fix itself to even the more obscure pieces of luggage out there. 

The larger-than-average vertical clearance of 4.4 cm makes it incredibly versatile and also guarantees that this lock will fit no matter where you place it. Another nod to the premium aspect of the lock is the black and white dial, which utilises maximum contrast for minimum confusion.

Possibly the brightest pack of locks there is, Travoce's six-pack guarantees that your luggage will be visible on the carousel – even if you have the simplest-looking black case. Having white numbers set to a black dial is another clever feature that will help you make no mistake when cracking your code. 

Better yet, the reinforced locking mechanism can handle over 70 kg of weight while the heavy-duty steel shackle is extremely cut-resistant. This multipack is an excellent choice for families who take their security breaches seriously, although if you're going solo or as a pair you can grab a smaller quantity if you prefer. 

Entering the more premium side of security, this option comes from Master Lock, a brand with an excellent reputation. Throughout their wide-reaching range of locks, there's a convincing level of quality that sees them with a loyal customer base of happy travellers. 

This is their three-digit dial that comes in a lucky dip of colours including black, orange, blue and purple, so you'd have to be happy with one of those! Colours aside, this is a dependable, well-made TSA-approved lock that's ready to serve your luggage for a good few years of use.

Another offering from the acclaimed mid-range brand OW-Travel, the body of these locks is again desirably small in size. Using the traditional key locking system, each lock has a set of two keys on its own individual ring for security. 

The biggest talking point of the locks is their oversized cables. With a vertical clearance of 4.3 cm when secured, these locks may be small in stature but they will be excellent for multi-zip cases. Bear the disadvantages of this in mind too though, as they may actually be a burden otherwise. 

OW-Travel are big players in the flight accessories market, producing an endless array of products that include luggage locks, straps and packing cubes to name but a few. This is their TSA-approved lock which is so miniature in stature that you'll barely notice it. 

OW-Travel have done away with the looping aspect of standard locks, including a straight cable with a plastic end instead. This makes it much more compact than most, but also makes it less about security and more about being as light and slim as possible. 

Here's another combination lock from a trusted brand with a three-digit dial, except this one benefits from a steel shackle padlock. This stronghold makes it much harder for thieves to cut their way into your valuables. 

Although the vertical clearance has not been stated, it's clearly a compact lock with a low clearance, which is another valuable asset for deterring thieves. The only slight hindrance is that the dial features a more budget styling of steel with black numbers, which may be tricky to make out for some people. 

The people behind the travel security brand Pacsafe have clearly done a fair share of exploring in their time. With this double cable design, you'll be able to not only lock your case but also lock it to a fixed object like a chair or table. 

Great for solo travellers, this means you'll be able to get some shut-eye or nip to the toilet in a cafe without the fear of your suitcase being stolen. Two cables also give you more flexibility in how your luggage can be locked. This dual design won't be for everyone, especially if travelling light, but it will be a must-have for some. 

First up is this popular pair of combination locks that come with a three-digit dial for security. Each lock features a steel cable that has been wrapped in vinyl for cut-resistance, which is a good thing because the vertical clearance is pretty high at 5.2 cm. 

While this is handy for fitting purposes, it does, unfortunately, give rise to people being able to cut the cable easier than a lock with a smaller one. However, at such a good price for the pair and with plenty of happy reviewers, you could certainly do a lot worse than this duo.
