The Guide to Standard TSA Locks: How to Set Your Suitcase Lock
Whether you are flying out of Brisbane for a massive European holiday or jetting off to the USA, the last thing you want to worry about is the security of your luggage. You’ve packed perfectly and checked your bags, but what happens if airport security needs to do a random inspection?
If you’re using an old school, non-approved padlock, you might arrive at your destination to find your lock snipped and your zippers ruined.
Here at Luggage Direct, we always recommend travelling with a TSA-approved lock. It is the absolute standard for modern travel. But what exactly is it, how does it protect your gear, and most importantly—how do you set the code?
Understanding TSA Locks: What You Need to Know
TSA approved locks are security devices designed to allow authorised airport and border security agencies to inspect checked luggage when required, without damaging the suitcase. TSA stands for the Transportation Security Administration, the agency that manages airport security in the United States, though the system is now global.
During screening, baggage may be opened for inspection as part of standard security procedures. If a suitcase is locked with a non-approved lock, officers are legally permitted to break the lock or force the zippers to gain access.
By using a TSA lock, travellers secure their suitcase using a personal combination, while security agencies can safely open and relock the case. You can easily spot a TSA lock by its visible approval symbol—the red diamond logo—giving you peace of mind that your luggage can be safely inspected and returned without unnecessary damage.
Why Aussie Travellers Need Them
- No More Destroyed Luggage: Avoid broken zippers and cut padlocks. TSA officers use a universal master key to safely open, inspect, and relock your bag.
- A Global Standard: Don't let the American name fool you. The Travel Sentry system is now used by security agencies in over 50 countries worldwide, including Australia, Japan, the UK, and across Europe.
- Built in Convenience: Most premium brands we carry at Luggage Direct—including Samsonite, American Tourister, Delsey, and Antler—feature high quality TSA combination locks built directly into the side of the case. No more losing tiny padlock keys!
How to Set Your TSA Lock (Standard Instructions)
Most suitcases sold at Luggage Direct use a TSA approved combination lock. When you purchase your suitcase, the combination is preset to the factory default: 0-0-0.
To unlock your suitcase out of the box, simply slide or push the TSA Lock release button to free the zippers from the housing.
To set your custom combination, follow these steps:
-
Press the Reset Button: Use the tip of a pen or pencil to press down the small reset button on the lock. (On some models, you push and hold the main release slide instead).
- Set Your Code: Turn the 3 dials to your desired combination (e.g., 1-2-3).
- Lock It In: Slide the main TSA release button across. You will see or hear the reset button pop back up.
- Secure Your Bag: Place the zippers back into the zipper housing.
To test your new combination:
- Mix up the dials and try sliding the TSA release button. It should remain locked and not move.
- Turn the 3 dials back to your newly chosen combination (e.g., 1-2-3). Slide the button across, and the zippers should pop out, unlocking your suitcase.
(To reset your combination in the future, simply set the dials to your current combination and repeat the steps above.)
Brand-Specific Lock Instructions
Got a unique lock style? While the standard steps above cover the vast majority of suitcases, some of our premium brands feature specialised locking mechanisms, such as clip-locks, dual-combination dials, or unique push-button releases.

Where is My Key? (And What if I Forget the Code?)
We get asked this all the time! The keyhole you see on your lock is strictly for TSA and Customs officers. They hold the universal master key that allows them to open your luggage. This key is not supplied with your luggage and cannot be purchased by the public.
Your security is your 3-digit combination. If you forget your code, the lock may need to be reset by the manufacturer or an authorised service agent. We highly recommend taking a quick photo of your new code on your phone or recording it safely!
