Can I Put a Lock on My Luggage?

Let’s be honest - travel is stressful. Even once you make it to your gate with your luggage left at the check-in counter, you worry about what could happen to it during transit. 

Someone you know has dealt with theft firsthand . You have heard lost luggage horror stories from others. The idea of investing in a luggage lock does cross your mind. Can I put a lock on my luggage, though? More importantly, should you lock your luggage, or am I being dramatic?

At Nobl, we equip both our carry-on luggage and checked luggage with dual- or triple-TSA combination locks so you can travel with confidence knowing your belongings are safe and secure. This also saves you the uncertainty of trying to find the right lock for your luggage and risking having it cut open by TSA if they need to inspect your suitcase.

These luggage locks are just one of the many exciting features on Nobl Travel luggage. From internal compression systems to built-in phone chargers, water bottle holders, and more - discover the difference our hard shell luggage can make in your next adventure today!

But let us get back to the topic in hand.

Why Should You Lock Your Luggage?

Should you lock your luggage? We don’t think you’re being dramatic at all! A 2023 poll found that roughly 7 out of 1,000 passengers have dealt with luggage mishandling in some way or another, which includes theft.

Peace of mind is important when you hit the road. It is worth investing in a strong, secure, TSA-approved luggage lock.

Protecting Against Theft During Transit

It’s no secret that airports are busy, high-traffic environments. Your checked bags pass through multiple hands and backrooms. Carry-ons may sit unattended at gates or be handled by a gazillion people before it makes to the cargo room.

While you should never assume the worst in people, even just the sight of a lock on your suitcase can help deter opportunistic theft during air travel. It may not stop determined thieves, but it discourages casual tampering and makes your luggage a less appealing target. It also helps reduce risk and keep belongings safe, even if it won’t stop all thieves. A locked suitcase still isn’t foolproof against determined interference.

Preventing Accidental Opening

Even premium suitcases with secure latches or reinforced zipper closures can still shift under pressure and risk accidentally opening in transit. After all there’s no shortage of pressure during those bumpy flights or when your suitcase comes into the hands of careless TSA employees.

The force of being tossed, stacked, or even wedged into tight spaces can be enough to pop compartments open, especially if it’s overpacked, so a simple zip ties option or a cable tie on the pulls can help prevent accidental opening and keep clothes and toiletries contained. A lock keeps everything contained, helping with basic safety for your belongings in transit and avoiding awkward baggage claim surprises or the stress of repacking in a public space.

You can also attach a small tie, since zap straps act as a tamper-evident backup if the bag is opened before arrival.

Peace of Mind in Shared Spaces

From hotel luggage rooms to cruise ship cabins, your suitcase may spend time in shared or semi-supervised settings, including a hotel room. A lock gives you control over what’s accessible and what’s not. Some travelers also add a luggage cover in shared spaces to make a bag easier to identify and discourage tampering.

It’s a small step that carries a big impact, especially if you’ve decided you want a little extra peace of mind when moving through unfamiliar places or are around people you don’t know. You can focus on being present for the journey rather than thinking about what your suitcase is up to.

Zip ties are a cost-effective option, and cable ties can show if luggage has been tampered with. Carabiner rings are another simple way to attach zipper pulls together in shared spaces.

Can I Put a Lock on My Luggage When Flying, Though?

So can I put a lock on my luggage when I fly? The answer may surprise you. This is actually something TSA encourages you to do! 

But, there’s a few key caveats to consider when it comes to leveraging a luggage lock. Not all locks are treated equally, especially when your bag is being screened by airport security.

Can You Lock Checked Luggage?

Locking checked luggage is allowed, but TSA agents still need to be able to inspect the bag if you’re flying from or within the United States. If you use a non TSA approved locks or a regular lock, TSA agents may cut it off during inspection, potentially damaging the bag. A forced inspection can also break the lock or leave it unsecured afterward.

Always, keep valuables and money in your carry on instead of checked baggage, regardless of the lock, and pack essential items with you while leaving replaceable items in your checked bag.

This is why TSA-approved locks exist. They can be opened with a universal key used by TSA personnel to keep your bag secure while still being compliant. Have the master key accessible in your carry on at all times.

Can I Lock My Luggage on an International Flight?

Things quickly change when you’re flying overseas. Our carry-on luggage size chart, for example, distinguishes between what you can fly with at home and abroad. Are the rules different for luggage locks on international flights as well?

You should get more specific and double-check the rules of the country you’re flying into. Review your airline’s checked-bag policy too, since each airline may set its own lock rules beyond general TSA guidance. TSA locks are recognized in several other countries (including Canada, the UK, Japan, and Australia), but not everywhere.

Some international airports may not have the tools to open TSA-style locks, and if local security personnel can’t open the lock, it may be cut during inspection.

What is a TSA Lock on Luggage?

You’ll notice we’ve referenced TSA-approved locks a few times throughout this guide, but what exactly are these - and why are they so important?

A TSA lock is a travel lock designed to meet the requirements of the Transportation Security Administration. These locks can be opened by airport agents using a secure, coded master key - meaning your bag can be inspected without damaging the lock or the suitcase. That allows security agents to open the bag with a special tool instead of cutting the lock. On soft-sided luggage, a zipper can still be easily opened with a pen or ballpoint pen, so the lock is more about deterring casual access than guaranteeing full protection.

You’ll recognize a TSA lock by the red diamond symbol, typically marked with “TSA007” or similar codes. It’s the standard for travelers flying to, from, or within the US. Many modern suitcases, including ours, come with built-in TSA-approved locks, so you don’t have to think twice.

How to Set Luggage Lock: Step-by-Step Guide

So you’ve got your new luggage, or perhaps you’ve just purchased a TSA-approved luggage lock for your old suitcase. Now what? It’s just a matter of understanding how to set the luggage lock correctly. Here are some tips on protecting your gear for an upcoming trip.

Step 1: Locate the Reset Button or Switch

Start by opening the lock. Look closely for a small reset button or pinhole usually located on the side or bottom of the lock mechanism. 

Some models, especially those built into the luggage frame like ours, will have you flip a switch near the dials to enter reset mode. Check for an arrow or indicator mark.

Step 2: Set a Combination You’ll Remember

Turn the number dials to your desired combination once the lock is in reset mode. Choose something easy to recall, but not obvious (avoid 000 or 123). Many travelers use digits tied to a memorable location or date - just make sure it’s not easily guessed by others.

Step 3: Lock and Test the Mechanism

Flip the reset switch back or press the button to finalize the code. Test the lock a few times before your next trip to make sure it opens and closes smoothly. If your lock features multiple latches, test each one.

What to Do If You Forget Your Lock Code

Unfortunately, TSA locks can’t be recovered if you forget the combo. Try common combinations you’ve used before, or methodically test all 1,000 possibilities (000-999). 

You can also contact our customer service team if the lock is built into your luggage. We may be able to help troubleshoot or guide a reset if the mechanism allows.

What If the Lock Gets Jammed or Stuck?

The luggage lock on Nobl Travel is covered by your warranty! However, you can check the dials to make sure they’re perfectly aligned. Even a slight misalignment can prevent the latch from opening.

Dust, debris, or pressure on the latch can also cause sticking. Gently clean the area and try again. Otherwise, get in touch with Nobl Support for a quick resolution. Our locks are made to perform, and we're here to help if they don't.
