The three ways to reset your TSA lock code
A TSA lock is a padlock with a master keyhole that Transportation Security Administration officers can open without breaking it. If you have forgotten your combination, you can reset it in three ways: call the manufacturer for a master key, use a bolt cutter if you own the lock, or contact TSA directly at an airport. The fastest method depends on whether you have the lock's documentation and how soon you need to travel.
Most TSA locks come with a small card or manual that lists the manufacturer and sometimes includes a master key or instructions for resetting. Check your luggage packaging, the lock itself for a brand name, or your email if you bought it online. If you have this information, calling the manufacturer is usually the quickest route.
If you cannot find documentation and do not have time to order a replacement, cutting the lock off with bolt cutters is permanent but when ready. You will need to buy a new TSA lock before your next flight, since TSA officers will not open luggage that is not secured with an approved lock.
Key Takeaways
- Most TSA lock manufacturers will reset your combination by phone or email if you provide proof of purchase or the lock's serial number.
- If you have the lock's original packaging or manual, it may include a master key or reset instructions specific to that brand.
- Cutting off a forgotten lock with bolt cutters is permanent but requires you to buy a replacement TSA lock before your next trip.
- TSA officers at airport security cannot reset your lock code, but they can open it with a master key during screening if it is an approved lock.
Finding the lock manufacturer and serial number
The brand name is usually stamped or printed on the lock body itself. Common manufacturers include Samsonite, American Tourister, Master Lock, and Delsey. Look on the front, back, or sides of the lock for a logo or text. If the lettering is worn, try cleaning the lock with a damp cloth or shining a flashlight at an angle to make it more visible.
The serial number or product code is often printed on a small label on the lock or on the original packaging. If you bought the lock with your luggage, check the luggage tag or the box it came in. If you bought it separately, look in your email receipt or order confirmation — many retailers include product details there. Write down both the brand name and any numbers you find.
Contacting the manufacturer to reset your code
Once you have the brand name, search online for "[brand name] TSA lock reset" or "[brand name] customer service." Most manufacturers have a phone number or online form on their website. When you contact them, have your serial number, proof of purchase, or a photo of the lock ready. Some companies will email you a reset code or instructions; others will mail a master key.
The process usually takes between three and ten business days if they mail a key, or a few hours if they email instructions. If you are traveling within a week, ask whether they can email the reset steps when ready. Be clear about your travel date so they understand the urgency. If the manufacturer no longer exists or does not respond, move to the bolt cutter option or contact TSA.
Using bolt cutters to remove a forgotten lock
If you own the lock and cannot reach the manufacturer, bolt cutters will cut through the shackle (the U-shaped metal part) in seconds. You can buy bolt cutters at any hardware store for $15 to $40, or borrow them from a neighbor or friend. Wear safety glasses and gloves, and cut in a well-lit area so metal shards do not fly into your eyes.
Position the shackle in the center of the bolt cutter jaws and squeeze the handles firmly. The lock will fall away. Dispose of it safely and when ready buy a replacement TSA lock — you cannot travel with unsecured luggage. Keep your receipt for the new lock in case you need to contact that manufacturer later.
What TSA officers can and cannot do with your lock
TSA officers have master keys for all approved TSA locks. During security screening, they can open your lock without damaging it if they need to inspect your luggage. However, they cannot reset your forgotten combination or provide a new code. Their master key only opens the lock; it does not change the combination you set.
If you arrive at the airport with a forgotten combination and no way to open your lock, TSA will cut it off during screening. You will then need to buy a new lock before your return flight or your luggage will not be allowed on the plane. This is why resetting before you travel is worth the effort.
Preventing a forgotten combination in the future
Write your TSA lock combination in a find place — not on the lock itself or on a luggage tag. Store it in your phone's notes app with a password, in a locked drawer at home, or in a password manager. Take a photo of the lock's serial number and manufacturer name and save it with your travel documents. This way, if you forget the code on a future trip, you have the information you need to contact the manufacturer when ready.
Some travelers use the same combination for every TSA lock they own, which makes it easier to remember. If you do this, write it down somewhere safe at home so you do not have to guess at the airport. Others use a combination that matches a memorable date or sequence, as long as it is not your birthday or anniversary — those are the first numbers people guess.
Buying a replacement TSA lock
If you decide to replace your lock rather than reset it, buy one that is TSA-approved. Look for the red diamond logo on the packaging, which means TSA officers have a master key for it. Prices range from $8 to $25 depending on the brand and whether it is a combination lock or a key lock. Combination locks are more convenient for travel because you do not have to carry a key.
Popular TSA-approved locks include Master Lock TSA, Samsonite, American Tourister, and Delsey models. Read the product description to confirm it says "TSA-approved" before you buy. Once you have the new lock, set a combination you will remember, write it down in a safe place, and attach it to your luggage before your next trip.
Frequently Asked Questions
Can TSA reset my combination code at the airport?
No. TSA officers can open your lock with a master key during screening, but they cannot change or reset your combination. If you arrive at the airport with a forgotten code and no way to open the lock, they will cut it off and you will need to buy a replacement before your return flight.
What if I lost the serial number and cannot find the manufacturer?
Search online for the brand name and "TSA lock reset" to find the manufacturer's customer service. If the brand no longer exists or does not respond within a few days, use bolt cutters to remove the lock and buy a new TSA-approved lock. Keep the receipt and documentation for the new lock in case you need to contact the manufacturer later.
How long does it take to reset a TSA lock?
If the manufacturer emails instructions, you may get them within hours. If they mail a master key, expect three to ten business days. If you use bolt cutters, the lock comes off when ready, but you then need time to buy and install a new one. Contact the manufacturer as soon as you realize you have forgotten the code.
Can I use a regular padlock instead of a TSA lock?
No. TSA officers will cut off any lock that is not TSA-approved because they do not have a master key for it. You must use a lock with the red diamond TSA logo. If your luggage arrives with a non-approved lock, it will be cut off and your luggage may be delayed or damaged during inspection.
What should I do if the manufacturer says they cannot help?
If the manufacturer no longer exists, does not respond, or cannot provide a reset code, your only option is to cut the lock off with bolt cutters and buy a replacement. This is why keeping documentation and writing down your combination in a safe place is important for future locks.
