How to Set Your Luggage Combination Lock – 2025 Guide for U.S. and International Travelers
Question: How do I set the combination lock on my suitcase or carry-on luggage?
Quick Answer: Start from the default 0-0-0 position, hold down the reset button or slide the lever, set your new 3-digit code, release the reset, and test it before locking. That’s it — your luggage is now secure and travel-ready.
Whether you’re heading on a weekend getaway or an overseas flight, securing your carry-on luggage and luggage set properly is a must.
With FAMISTAR’s TSA-approved locks, both U.S. and international travelers can protect their belongings while complying with TSA-approved luggage standards recognized worldwide.
Why setting your suitcase lock correctly matters
According to the Transportation Security Administration, setting your combination lock properly helps ensure that airport agents can inspect bags without damaging them. Beyond the U.S., many airports in the Travel Sentry network of airports follow the same TSA-compatible system, meaning your suitcase can be opened safely for screening in over 70 countries.
By taking a minute to correctly configure your lock, you reduce the risk of getting locked out, losing valuables, or having your suitcase forced open during inspection. It’s a small action that prevents big travel headaches.
Step-by-Step: How to Set Your Luggage Combination Lock
- Start from the factory default (usually 0-0-0). Confirm that the zippers are inserted into the lock slot and the suitcase is open before setting a new code.
- Find the reset mechanism. Many locks include a small button or switch near the dials; a few may require a pointed tool, as shown in Master Lock’s official combination setup guide.
- Hold or slide the reset mechanism. Keep it pressed while turning each dial to your chosen code — for example, 4-2-9 — avoiding easily guessed patterns like 1-2-3.
- Release the reset button. This saves your new combination. Some locks may require returning a lever to its original position.
- Test your new code. Rotate the dials away and back again to confirm that it unlocks smoothly.
- Record your code securely. Keep it written in a secure note or cloud document, as recommended in the U.S. State Department traveler’s checklist.

Understanding TSA-Approved Locks
TSA-approved locks were created through collaboration between the U.S. Transportation Security Administration and Travel Sentry to allow security officers to open and re-lock checked luggage without damaging it. Each lock features a small keyhole compatible with official TSA master keys used by security agents at screening checkpoints.
Look for the red diamond logo on your FAMISTAR suitcase — it signifies that your lock complies with TSA’s inspection standards and can be opened safely during screening. For international travel, these same locks are recognized at customs agencies in regions like the EU, Japan, and Australia under the global Travel Sentry partnership.
Tips for International Travelers
When crossing borders, rules about locked luggage can vary, but most major countries follow the same TSA-compatible guidelines. Before your next trip abroad, review the U.S. Customs and Border Protection traveler information and check that your suitcase uses a Travel Sentry-approved TSA lock. This ensures compliance with inspection standards while maintaining personal security.
- Keep your combination accessible in case customs requests inspection.
- Do not pack prohibited items; review TSA’s “What Can I Bring” list before flying.
- Always double-check your suitcase after customs to confirm the lock was re-secured correctly.
Frequently Asked Questions (FAQ)
Can I use the same code for all pieces in my luggage set?
Yes, though varying your codes slightly increases security. Consistency helps if you’re managing multiple pieces, but always store combinations in a secure location before travel.
What if I forget my combination?
If you forget the combination, try the factory default first. If it fails, most TSA-approved models can be reset using manufacturer-specific guidance available on the Travel Sentry Help Center.
Can TSA agents open my lock without my code?
Yes. U.S. TSA officers can open approved locks using a master key system — an essential feature of TSA-approved security standards — allowing safe inspection without cutting your lock.
Do I need a TSA lock for international travel?
It’s highly recommended. TSA-approved locks are recognized in over 70 countries through the Travel Sentry partner program, making them ideal for international itineraries.
