How to Open a Samsonite Lock When You Can’t Remember the Numbers

It is common to find a Samsonite suitcase in storage or purchase a pre-owned one only to realize the combination is unknown. If the numbers are a total mystery, you don’t need to break the lock to get inside. There are proven methods to identify the current password so you can open the bag and reset the combination to your own preferred digits.

The most common way to find an unknown password on a Samsonite lock is the mechanical bypass method. Peer into the space beside the dials with a flashlight and find the small flat indentation on the axle of each wheel. Turn the wheels until these notches are all aligned and facing the same direction. From this point, shift the numbers together until the release button works.

Once the bag is open, the combination currently showing is the “lost” password. You can now easily erase it and set your own. Locate the small reset button on the lock housing and press it down with a pen or paperclip. Select your new 3-digit combination and slide the release button to confirm the change.

To ensure you never have to deal with a forgotten code again, consider using a number that has personal significance but is not easily guessed. Storing a photo of the new code on your smartphone ensures that you have a backup reference if you ever find yourself unable to remember the digits again.

 Can I unlock my suitcase if I forgot the combination?

Yes. Most luggage locks have a mechanical flaw that allows you to decode them using the “gap detection” method shown in our video. You don’t need to cut the zipper.

What if my lock does not have a reset button?

If there is no visible reset button, simply push the main latch towards the “open” position and hold it there while rotating the dials to set your new code.

Can I use a Master Key to open it?

Absolutely. If your lock has a red diamond logo, it is a TSA lock. You can buy a universal TSA Master Key online to open it instantly.

My lock is jammed, what should I do?

Try spraying a lubricant like WD-40 inside. If it’s still stuck, the internal spring might be broken, and you may need to replace the lock head.

What if I don’t have a reset button on my lock?

If there is no visible reset button, your lock likely uses the “hold-and-turn” method. Push the main release button towards the “open” position and hold it there while you rotate the dials to your new code.

Can I use a TSA Master Key to open my suitcase?

Yes! TSA Master Keys (like TSA007 or TSA002) are designed to open these locks without the combination. You can buy these keys online if you are completely locked out.

My lock is jammed and won’t open with the correct code.

This happens when the internal tumblers get stuck. Try spraying a little WD-40 or lubricant into the mechanism. If that doesn’t work, verify the code again using the “gap detection” method shown in our video.

Is it possible to pick a 3-digit luggage lock?

Yes, it is actually quite easy. Most 3-digit locks provide visual or tactile feedback (small gaps) that reveal the correct combination. Our guide above shows you exactly how to find them.
