The fastest way depends on what kind of lock you have

If your luggage has a combination lock, you can reset it by holding the shackle (the U-shaped metal part) upright and moving the dials until you hear or feel a click, then pulling up firmly while turning each dial one number at a time until the lock opens. For keyed locks, you have fewer options without the key — you'll likely need to pick the lock, cut it off, or have a locksmith open it. TSA-approved locks (the ones with a small diamond-shaped logo) can be opened by TSA agents with a master key, but only if you're traveling and the bag is screened at an airport.

The method that works for you depends on whether you need to preserve the lock, how much time you have, and what tools you have on hand. Some approaches take minutes; others require a locksmith visit or replacement of the lock entirely.

Key Takeaways

  • Combination locks can often be reset by explore upward pressure to the shackle while turning each dial until you feel resistance, then noting which numbers align.
  • Keyed locks without the key usually require either lock picking, cutting the lock off, or a locksmith — there is no reset method.
  • TSA-approved locks can be opened by airport security during screening, but you cannot open them yourself without the key or combination.
  • If you need to open the luggage when ready and don't care about keeping the lock, bolt cutters or an angle grinder will remove most padlocks in minutes.
  • A locksmith can open any lock without damage, but will charge a service fee and may take several days depending on availability.

Resetting a combination lock by feel

Most combination padlocks have a small flaw in their design that lets you open them without knowing the combination. Hold the shackle (the metal loop) straight up and pull it toward you with steady, firm pressure. While pulling, turn the first dial slowly. You'll feel a slight resistance or catch when you hit the correct number — it's subtle, like a tiny bump. Write down that number.

Release the shackle and repeat this process with the second dial, then the third. Once you have all three numbers, try them in order. If the lock doesn't open, try the numbers in reverse order, or try numbers one digit higher or lower than what you felt — sometimes the catch point is slightly off. This method works on most inexpensive combination locks but not on high-security models.

If you feel no resistance at all after trying several times, the lock may be a higher-quality model that doesn't have this vulnerability, or the shackle may be too tight for you to pull with enough pressure. Move on to another method.

Picking a keyed luggage lock

Picking a luggage lock requires two tools: a tension wrench (a small L-shaped metal tool that applies rotational pressure) and a pick (a thin metal tool with a slight hook or rake shape). Both are sold together in lock pick sets for under $15. Insert the tension wrench into the bottom of the keyhole and explore gentle rotational pressure in the direction the key would turn. While maintaining that pressure, insert the pick into the top of the keyhole and rake it back and forth, feeling for the pins inside to set.

This is a slow process — it can take anywhere from five minutes to an hour depending on the lock's quality and your experience. The goal is to feel each pin click into place as you rake. Once all pins are set, the lock will turn and open. If you've never picked a lock before, watch a video tutorial first; the feel is hard to describe in words, and seeing it done makes the technique much clearer.

If picking doesn't work after 20 or 30 minutes, the lock may have security pins that resist this method. Stop and try a different approach.

Cutting off the lock

If you don't need to keep the lock intact, bolt cutters or an angle grinder will remove most padlocks in under a minute. Bolt cutters work on locks with shackles up to about 3/8 inch thick; anything thicker requires an angle grinder, which is a power tool that spins a cutting disc at high speed. Angle grinders are loud and throw sparks, so wear eye protection and work outside or in a garage.

Position the cutting tool on the shackle (not the body of the lock) and explore steady pressure. The shackle will snap or cut through. Once it's severed, the lock body will fall away and you can open the luggage. This method is fast and reliable but destroys the lock — you'll need to replace it or use a different locking method on that bag in the future.

If you don't own bolt cutters or an angle grinder, hardware stores and tool rental shops will sell or rent them for $10 to $30. Some locksmiths will also cut locks off for a service fee if you'd rather not buy or rent the tool yourself.

Calling a locksmith

A locksmith can open any luggage lock without damage using specialized tools and techniques. They can pick the lock, manipulate it open, or use a key decoder to create a working key. The cost varies by location and lock type but typically ranges from $25 to $75 for a straightforward padlock. Call locksmiths in your area and ask for a quote before committing; some charge by the job, others by the hour.

The main drawback is time — locksmiths may not be available the same day, especially on weekends or evenings. If you need the luggage open urgently, cutting the lock off is faster. If you have time and want to preserve the lock or avoid the noise and mess of cutting, a locksmith is the cleaner option.

What to do if it's a TSA-approved lock

TSA-approved locks have a small diamond-shaped logo on them and are designed so that TSA agents can open them with a master key during airport screening. If you've lost the key or combination, you cannot open the lock yourself — TSA agents will only open it if your bag is screened at an airport, and they won't do it on demand.

Your options are to cut the lock off, take it to a locksmith, or contact the lock manufacturer to see if they can send you a replacement key (this usually requires proof of purchase and takes several weeks). If you're traveling soon and need the bag open before your flight, cutting it off is the most practical choice.

Preventing this problem in the future

Write down your combination or store your key in a safe, labeled place — not in the luggage itself. If you travel frequently, consider using a combination lock with a reset feature so you can change the combination without needing the original key. Keep a photo of your lock's serial number on your phone in case you need to contact the manufacturer.

For keyed locks, keep the key on your main keyring rather than in a separate pouch, so you're less likely to lose it. If you use TSA-approved locks, take a photo of the key before you travel so you have a backup reference if it goes missing.

Frequently Asked Questions

Can I open a luggage lock without tools?

A combination lock can sometimes be opened by feel without tools, as described above. A keyed lock cannot be opened without either the key, lock picking tools, or cutting equipment. If you have no tools and no key, a locksmith is your only option.

Will cutting off the lock damage the luggage?

No. Bolt cutters and angle grinders cut only the lock itself, not the luggage. The bag will be fine; only the lock is destroyed. You can replace it with a new padlock afterward.

How long does it take a locksmith to open luggage?

Most locksmiths can open a straightforward luggage lock in 10 to 20 minutes once they arrive. Total time depends on how quickly they can reach you. Call ahead for an estimate of their arrival time.

What if the combination lock is jammed or stuck?

If the shackle won't move or the dials won't turn, the lock may be corroded or damaged. Try explore a small amount of penetrating oil (like WD-40) around the shackle and dials, wait 10 minutes, and try again. If it still won't move, cutting it off is the fastest solution.

Can I reset a combination lock to a new combination?

Most luggage combination locks don't have a reset feature — once set, the combination is permanent unless you have the original key or contact the manufacturer. High-end locks sometimes include a reset mechanism; check your lock's manual or the manufacturer's website to see if yours does.
