How to Use TSA Locks in 4 Steps

Whether you're heading out on a weekend getaway or a long-haul international trip, securing your luggage is essential. One of the most traveler-friendly ways to do this is by using TSA-approved locks. These locks are designed to keep your belongings safe while allowing Transportation Security Administration (TSA) agents to inspect your luggage without damaging the lock.

Unlike traditional locks, TSA locks feature a universal access system that enables agents to use a master key to open and relock your suitcase if needed. This means you can travel with peace of mind, knowing your luggage is secure and compliant with airport security protocols.

In this guide, we’ll walk you through how to use TSA locks in 4 simple steps, plus answer common questions travelers have about them.

Step 1: Set Your Personal Combination

Most TSA locks come with a default code, usually 0-0-0, which you’ll want to change before your first trip. Whether your lock has a 3-digit or 4-digit combination, the process is generally the same:

1. Locate the reset mechanism: This could be a small button on the side or bottom of the lock, or a lever you need to push or pull.
2. Press or move the reset tool: Hold it in place while you set your new combination.
3. Choose your code: Rotate the dials to your desired numbers. Make sure it’s something memorable but not easily guessed.
4. Release the reset button or lever: Your new combination is now set.

💡 Pro Tip: Write down your code and store it somewhere safe—just in case you forget it later.

Step 2: Lock Your Suitcase

Once your combination is set, locking your suitcase is easy:

1. Align the zipper pulls: Most TSA locks are integrated into the suitcase or come with a clasp that secures the zipper tabs.
2. Insert the zipper pulls into the lock: Push them in until you hear a click.
3. Scramble the dials: Rotate the numbers away from your combination to lock the suitcase.

Your luggage is now secure and ready for travel.

Step 3: Unlock Your Suitcase

To open your suitcase:

1. Enter your combination: Rotate the dials to match your personal code.
2. Release the lock: Depending on the model, this may involve pressing a button or sliding a latch.
3. Remove the zipper pulls: Your suitcase is now open.

If the lock doesn’t open, double-check the combination and ensure the dials are aligned precisely.

Step 4: TSA Master Key Access

TSA locks feature a small keyhole labeled with a red diamond symbol—this is for TSA agents only. If your bag is selected for inspection, agents can use a master key to open the lock without damaging it.

This feature is what makes TSA locks ideal for air travel. You won’t return to your luggage to find a broken lock or cut zippers, just a notice that your bag was inspected.

Common Questions About TSA Locks

Can TSA Locks Be Cut Off?

While TSA agents have master keys, in rare cases where a lock is malfunctioning or inaccessible, it can be cut off. However, this is uncommon and usually a last resort. Using a TSA-approved lock significantly reduces the risk of damage during inspection.

Do TSA Locks Come With Keys or Only Combinations?

Most TSA locks are combination-based, but some models include a key for personal use. However, the TSA master keyhole is not accessible to travelers; it’s strictly for security personnel. If you prefer a key-based lock, make sure it’s TSA-approved and keep your key in a secure place.

How Do I Reset the Combination on a TSA Lock?

To reset your TSA lock:

1. Open the lock using your current combination.
2. Locate the reset button or lever.
3. Press or move it into the reset position.
4. Set your new combination.
5. Release the reset mechanism.

Always test the new code before locking your suitcase again.
