Most luggage locks reset by pushing a button or lever while turning the dials

The method depends on your lock type. TSA-approved combination locks (the kind with a small diamond-shaped button on the back) reset by pressing that button inward while you turn the dials to your new code. Dial-only locks with no button typically reset by pulling the shackle (the U-shaped metal part) upward hard while turning the dials. Some locks require you to set the code first, then push the button to lock it in. A few older models need you to open the lock, then turn a small screw on the inside to change the combination.

The exact steps vary by manufacturer, so your first move is to check the lock itself for printed instructions—many have them stamped or engraved on the back or bottom. If you cannot find them there, look for a model number on the lock and search the manufacturer's website. Samsonite, American Tourister, and other major brands post PDF guides for their locks online.

If you have lost the original code and cannot find instructions, you may need to contact the luggage maker directly with proof of purchase, or take the bag to a luggage repair shop. Some locksmiths can also reset combination locks, though this costs money and takes time.

Key Takeaways

  • TSA-approved locks reset by holding the button while turning the dials to your new code.
  • Dial-only locks usually reset by pulling the shackle up hard while you change the combination.
  • Check the lock itself or the luggage manufacturer's website for the exact steps for your model.
  • If you have forgotten the current code, contact the luggage maker or a locksmith rather than forcing the lock.
  • Write down your new code somewhere safe outside the luggage in case you forget it later.

TSA button locks: the most common type on modern luggage

If your lock has a small diamond or rectangular button on the back, it is a TSA-approved lock. These are standard on most new luggage sold in the United States. To change the code, press and hold the button inward (you may need to use a pen or small tool to reach it), then turn each dial to the number you want. The button stays pressed the whole time you are setting the code.

Once all three dials show your chosen numbers, release the button. The lock is now set to your new code. Test it by closing the lock and spinning the dials, then opening it again with your new combination to make sure it works before you travel.

Some TSA locks have a button you push down instead of in. The principle is the same: hold it down while turning the dials, then release. If you are not sure which direction to push, try both gently—the button should move slightly in the correct direction.

Dial-only locks: resetting without a button

Older luggage and some budget models have locks with only three dials and no button or lever. These reset differently. Pull the shackle (the metal U-shaped part at the top of the lock) straight up as hard as you can while turning the dials to your new code. The shackle should be under tension the entire time you are changing the numbers.

Once you have set all three dials to your new combination, release the shackle. The lock should now open only with the new code. Like TSA locks, test it when ready to confirm it works.

If the shackle does not move or feels stuck, do not force it—you may break the lock. Instead, look for a small screw on the inside of the lock body (visible when the lock is open). Some models require you to turn this screw with a small screwdriver to reset the combination. Check the manufacturer's instructions before trying this.

Finding your lock's instructions if you have lost them

The fastest way to find reset instructions is to look at the lock itself. Many locks have the steps printed or stamped on the back, bottom, or inside. Use a flashlight if the text is small or faded. If nothing is printed on the lock, look at your luggage for a model number or brand name, then search "[brand name] combination lock reset" online.

Most major luggage makers—Samsonite, American Tourister, Delsey, Away, and others—post lock reset guides as downloadable PDFs on their websites. You can also call their customer service line with your luggage model number and they will walk you through the steps over the phone. Keep your receipt or proof of purchase handy if you call, as some companies ask for it.

If your luggage is very old or the brand is no longer in business, a luggage repair shop in your area may be able to help. They see many lock types and can often reset or replace locks for a fee, usually between $15 and $40 depending on the lock type and your location.

What to do if you have forgotten your current code

If you cannot remember the code and the lock is closed, you cannot reset it using the button or shackle method—you need to open it first. Trying to force a combination lock usually damages it and may damage your luggage. Instead, contact the luggage manufacturer with proof of purchase (receipt, credit card statement, or order confirmation). They can often provide the original code or send you a replacement lock.

A locksmith can also open the lock without damaging it, though this costs money and may take a few days depending on their schedule. Call ahead and ask for a quote. Some locksmiths specialize in luggage locks and can do the work quickly; others may need to order parts.

If the lock is old and inexpensive to replace, you may decide it is simpler to buy a new luggage lock than to pay for a locksmith. Combination locks cost $10 to $30 and take five minutes to install if your luggage has a lock slot. If your luggage does not have a built-in lock slot, you can use an external padlock or cable lock instead.

Choosing a strong new code and keeping it safe

When you set your new code, avoid obvious numbers like 000, 123, or your birth year. A random three-digit combination is harder for someone to guess. Write your new code down and store it somewhere safe outside your luggage—a notes app on your phone, a password manager, or a piece of paper in your desk at home. Do not write it on a sticker and attach it to the luggage.

If you travel frequently, consider using the same code for all your luggage locks so you only have to remember one combination. Just make sure it is something you will not forget, because resetting a lock you have already locked is time-consuming.

For TSA-approved locks, remember that TSA officers have master keys and can open your lock during security screening without damaging it. This is a feature, not a flaw—it means your bag can be inspected without breaking the lock. Do not use a non-TSA lock on luggage you plan to check on a flight, as TSA may cut it off if they need to inspect your bag.

Frequently Asked Questions

Can I change my luggage lock code without opening it first?

No. You must open the lock before you can reset the code. If you have forgotten the combination, you will need to contact the manufacturer or a locksmith to open it first. Once it is open, you can follow the reset steps for your lock type.

What if the button on my TSA lock is stuck and will not press?

Try using a pen, paperclip, or small tool to press it instead of your finger—the button is small and may be hard to reach. If it still will not move, the lock may be broken. You can replace it with a new TSA-approved lock from any luggage or travel store, or contact the luggage manufacturer to order a replacement lock.

Is it safe to use the same combination for all my luggage?

Yes, it is safe and convenient. Using one code across all your bags means you only have to remember one combination. Just make sure it is not an obvious number like 000 or 123, and keep it written down somewhere find outside your luggage.

Do I need a TSA lock or can I use any combination lock?

TSA-approved locks are recommended for checked luggage on flights because TSA officers can open them with a master key without damaging your bag. Non-TSA locks may be cut off if your bag needs inspection. For carry-on bags or non-flight travel, any combination lock works.

How often should I change my luggage lock code?

You only need to change it if you have shared the code with someone you no longer trust, or if you suspect someone saw you enter it. For regular travel, you can keep the same code indefinitely as long as you remember it and it is not an obvious number.
