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. 

Whether you’ve dealt with theft firsthand or just heard horror stories from others, you might be interested in the idea of investing in a luggage lock. Can I put a lock on my luggage, though? More importantly, should you lock your luggage, or is this being a bit dramatic?

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!

Why Should You Lock Your Luggage? The Case for a Luggage Lock

Maybe you’re just being paranoid…should you lock your luggage? Let us be clear: 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.

If for no other reason than your own peace of mind when you hit the road, it’s worth investing in a strong, secure, TSA-approved luggage lock. Here’s why we won’t travel without them anymore.

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 placed several rows away during flight.

While you should never assume the worst in people, even just the sight of a lock on your suitcase is a deterrence against opportunistic theft. It may not stop a determined thief, but it discourages casual tampering and makes your luggage a less appealing target.

Preventing Accidental Opening

Even premium suitcases with secure latches or reinforced zippers can shift under pressure - and there’s no shortage of pressure during those bumpy flights or when your suitcase comes in 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. A lock keeps everything contained, helping avoid awkward baggage claim surprises or the stress of repacking in a public space.

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. A lock gives you control over what’s accessible and what’s not. 

It’s a small step that carries a big impact, especially when you're moving through unfamiliar places or 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.

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?

You’re allowed to lock your checked luggage, but it has to be accessible by TSA agents if you’re flying from or within the United States. They’re authorized to break the lock if they can’t open it for inspection, or even damage the suitcase altogether - whatever it takes to get a peek inside.

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. 

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. 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, which could result in cut locks during customs inspections. 

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.

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. Every lock we build into our luggage meets this standard, 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?

This is not something you’ll have to worry about with the luggage lock on Nobl Travel - it’s 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.
