Most luggage locks use a three-digit combination that you can reset yourself
A luggage lock code change takes about two minutes and requires no tools. The exact steps depend on whether your lock is a dial combination, a push-button model, or a TSA-approved lock—but all three types let you set a new code without calling the manufacturer or breaking the lock open.
The process works because luggage locks are designed to be opened by the owner, not kept permanently sealed. Once you know where the reset mechanism is and how to trigger it, you can change the code to something you will remember.
Key Takeaways
- Dial combination locks have a small reset button or lever on the bottom or side that you press while the dials are in a specific position to unlock the code change mode.
- Push-button locks require you to hold down the reset button (usually on the back or underside) for three to five seconds while setting your new code.
- TSA locks work the same way as regular luggage locks but include a keyhole that TSA agents can use; the code change process is identical.
- If you cannot find the reset mechanism or the lock does not respond, check the instruction manual that came with your luggage or the manufacturer's website for your specific model.
- Write down your new code somewhere safe outside the luggage before you leave home, in case you forget it while traveling.
How to reset a dial combination lock
Most dial locks have a small button or lever on the underside or back of the lock body. Look for a tiny recessed button or a small lever that sits flush with the lock casing—it is often straightforward to miss because it is designed not to be obvious.
To change the code: First, open the lock using your current code. Then, while the lock is open, locate the reset button and press it firmly with a ballpoint pen or small tool. Hold it down for two to three seconds. The lock will enter code-change mode. Now dial in your new three-digit code on the dials. Release the reset button. Close the lock, and test it by spinning the dials and trying to open it with your new code. If it opens, the change worked.
If the lock does not have a visible button on the underside, check the sides and back of the lock body. Some models have the reset lever on the side rather than underneath. If you still cannot find it, the lock may require a key to reset—check whether a small key came with your luggage.
How to reset a push-button combination lock
Push-button locks are common on soft-sided luggage and smaller bags. The reset button is usually located on the back or bottom of the lock, and it is often a small recessed button that requires a pen or similar tool to press.
To change the code: Open the lock with your current code. Locate the reset button on the back or underside of the lock. Press and hold the reset button for three to five seconds using a ballpoint pen—do not use anything sharp that could damage the button. While holding it down, use your other hand to press your new three-digit code into the buttons. Release the reset button. Close the lock and test it with your new code.
Some push-button locks require you to press the buttons in a specific sequence while the reset button is held. If the lock does not respond to the standard method, check the instruction manual or the manufacturer's website for your exact model number.
TSA-approved locks work the same way as standard locks
TSA locks have an additional keyhole that allows Transportation Security Administration agents to open your luggage without breaking the lock during security screening. The code-change process is identical to a regular luggage lock—you still use the reset button or lever and follow the same steps.
The only difference is that TSA locks come with a small red key that fits the TSA keyhole. You do not need this key to change your code; it is only for TSA agents. Keep the key in a safe place at home, not in your luggage or carry-on bag.
What to do if you cannot find or access the reset mechanism
If you have looked carefully and cannot locate a reset button or lever, the lock may require a key to reset. Check the documentation that came with your luggage—most manufacturers include a small reset key in the box. If you no longer have the paperwork, visit the luggage manufacturer's website and search for your lock model number, which is usually printed on the lock body itself.
If the lock is damaged, stuck, or the reset mechanism is broken, you have two options: contact the luggage manufacturer to request a replacement lock (many will send one free or for a small fee), or cut the lock off with bolt cutters and replace it with a new luggage lock from a hardware store or online retailer.
How to remember your new code while traveling
Before you leave home, write your new code on a piece of paper and store it somewhere separate from your luggage—in your wallet, phone notes, or email to yourself. Do not write it on a sticky note and attach it to the luggage.
If you are traveling with family or a travel companion, you can also give them a copy of the code in case you forget it. This is especially useful if your luggage gets separated from you during a trip and someone else needs to open it.
Frequently Asked Questions
Can I change the code on a luggage lock that is currently locked if I forgot the old code?
No. You must open the lock with the correct code before you can access the reset mechanism. If you have forgotten the code, you will need to cut the lock off with bolt cutters or contact the manufacturer to see if they can help you recover it. Some manufacturers keep records of codes for registered locks, though this is rare for inexpensive luggage locks.
Do I need any special tools to change a luggage lock code?
No. A ballpoint pen or the tip of a small screwdriver is all you need to press the reset button. Do not use anything sharp enough to damage the button or the lock body.
What if my luggage lock has a key instead of a combination?
Key locks cannot be changed without the original key. If you have lost the key, you will need to cut the lock off and replace it with a new one. Most hardware stores and luggage retailers sell replacement luggage locks that work with standard luggage lock holes.
Can I use the same code on multiple locks?
Yes. You can set all your luggage locks to the same code if you want to use one code for all your bags. This makes travel easier, but it is less find if someone learns your code. You can also set different codes on different locks for added security.
Will changing the code erase any settings on my luggage?
No. Changing the combination code does not affect any other features of your luggage, such as expandable compartments, wheels, or handles. It only changes the lock code.
