What to do when you cannot find your TSA lock key

If you have lost the key to your TSA lock, you have three practical options: contact the manufacturer for a replacement key, cut or drill the lock open, or have a locksmith do it for you. The fastest route depends on whether you need the lock again later and how soon you need access to your luggage.

TSA locks are designed to be opened by TSA agents at security checkpoints using a master key, but they are not designed to be easily opened by the owner without the original key. The manufacturer will not send a replacement key based on ownership alone — they have no way to verify you own the lock. This means your realistic options are destructive (cutting or drilling) or paying someone else to do it.

Key Takeaways

  • The lock manufacturer cannot issue a replacement key without proof of purchase and the original key code, which most people do not have.
  • Cutting the lock with bolt cutters or an angle grinder takes 5 to 15 minutes and permanently destroys the lock.
  • Drilling out the lock cylinder is quieter than cutting and also takes 10 to 20 minutes, but the lock cannot be reused afterward.
  • A locksmith can open the lock in 15 to 30 minutes for a service call fee, typically $50 to $150 depending on your location.
  • If you need the lock for future travel, buying a new TSA lock costs $10 to $25 and is often faster than waiting for a locksmith.

Contacting the manufacturer for a replacement key

Most TSA lock manufacturers, including Samsonite, American Tourister, and smaller brands, will not send a replacement key to someone who calls without the original key code. The key code is usually printed on a small card that came with the lock or engraved on the lock itself — often on the back or bottom of the lock body.

If you still have that card or can read the code on the lock, contact the manufacturer's customer service with the code and a photo of the lock. Some manufacturers will mail a replacement key for a small fee, usually $5 to $15 plus shipping. This process takes one to three weeks. If you cannot find the key code, the manufacturer will tell you they cannot help, and you will need to choose another method.

Cutting the lock with bolt cutters or an angle grinder

Bolt cutters are the simplest tool for destroying a TSA lock quickly. You need a pair rated for the lock's shackle diameter — most TSA locks have a shackle between 3/8 inch and 1/2 inch thick, so standard bolt cutters from a hardware store will work. Position the shackle in the cutter's jaws and squeeze hard. The lock will snap open in one or two cuts.

An angle grinder is faster if you have one and know how to use it safely. Wear eye protection and gloves, and cut across the shackle where it enters the lock body. The cut takes 5 to 10 minutes. Bolt cutters take longer — 10 to 15 minutes — but require no power and are safer for a first-time user. Both methods destroy the lock permanently and cannot be reversed.

Drilling out the lock cylinder

Drilling is quieter than cutting and works well if you are in a hotel or shared space. You need a drill with a metal bit slightly smaller than the lock cylinder's diameter — usually 1/4 inch to 3/8 inch. Clamp the lock firmly in a vise or have someone hold it steady. Drill straight into the center of the keyhole until the bit breaks through the cylinder's back.

Once the cylinder is breached, the lock mechanism inside will be damaged enough that you can often turn the shackle by hand or with a screwdriver. If it does not turn, drill deeper or use a screwdriver to pry the cylinder out. The whole process takes 10 to 20 minutes depending on the lock's quality and your drill's power. Like cutting, drilling destroys the lock and cannot be undone.

Hiring a locksmith to open the lock

A locksmith can open most TSA locks without destroying them, though the cost and time vary by location and the locksmith's experience with luggage locks. Call a local locksmith and describe the lock — they will give you a quote, usually $50 to $150 for a service call. Some locksmiths can open the lock in 15 to 30 minutes using picking tools or by drilling and then replacing the cylinder.

The advantage of a locksmith is that some can preserve the lock if you want to keep it. The disadvantage is that you have to wait for an appointment, and the cost is often more than buying a new lock. If you need access to your luggage today, a locksmith is slower than cutting or drilling it yourself. If you need the lock for future travel and want to avoid buying a new one, a locksmith may be worth the wait and cost.

Buying a new TSA lock instead

A new TSA lock costs $10 to $25 at most retailers, including Amazon, Target, Walmart, and luggage stores. You can have one delivered the same day or next day if you order online, or pick one up in a store within an hour. This is often faster and cheaper than waiting for a locksmith, and you get a lock with a key you actually have.

If your luggage has a built-in lock that you cannot remove, you cannot replace it without replacing the luggage itself. In that case, a locksmith or drilling is your only option. If your lock is a separate padlock attached to a zipper pull, buying a new one is almost always the fastest solution. Keep the new key in a safe place — many people store a photo of the key code in their phone or email it to themselves.

Preventing this problem in the future

Take a photo of your TSA lock's key code or the card it came with and store it in your phone or email. If you lose the physical key, you will have the code and can contact the manufacturer. Write the code on a small piece of tape and stick it inside your luggage, away from the lock itself — if your luggage is searched, TSA agents will see the code and know you own the lock.

Keep your key in a small envelope or labeled bag in your carry-on luggage, not in the checked bag. Many people lose keys because they pack them in the same bag as the lock. If you travel frequently, consider buying a TSA lock with a combination dial instead of a key — you cannot lose a combination, though you can forget it. Write the combination down and store it separately from your luggage.

Frequently Asked Questions

Can a TSA agent open my lock if I lost the key?

Yes. TSA agents have a master key that opens all standard TSA locks at security checkpoints. You do not need your own key for TSA to inspect your luggage. However, if you want to open the lock yourself before or after travel, you will need to use one of the methods described above.

Will the lock manufacturer replace a lost key if I have the receipt?

Most manufacturers require the key code printed on the original card or engraved on the lock itself, not just a receipt. If you have the receipt but not the code, contact the manufacturer and ask — some will help if you can prove the purchase date and provide a photo of the lock. Many will not.

Is it legal to drill or cut open my own lock?

Yes, you can destroy your own lock. It is legal to cut or drill a lock you own. If the lock is attached to luggage you do not own, or if you are opening someone else's lock, that is a different matter.

How long does it take a locksmith to open a TSA lock?

Most locksmiths can open a TSA lock in 15 to 30 minutes once they arrive. The total time includes the service call fee and wait for an appointment, which can be hours or days depending on availability in your area.

What should I do if my luggage lock is built into the suitcase?

Built-in locks cannot be removed or replaced separately. Your options are drilling the lock, having a locksmith open it, or replacing the entire suitcase. Drilling is usually the fastest and cheapest choice for a built-in lock you cannot access from the outside.
