For most modern Samsonite luggage, you do not need a physical key because they are equipped with integrated TSA-approved combination locks. When you purchase a new suitcase, the "keyhole" you see is actually intended exclusively for TSA agents, who possess a master key that allows them to inspect your bag without damaging the lock or the zipper. For the owner, the lock is operated by setting a three-digit code (usually defaulted to 0-0-0). If you have an older Samsonite model or a specific "hardside" case without a combination pad, it may have come with a small physical key; however, in 2026, these are increasingly rare as digital and combination security is the industry standard. If you lose your combination, Samsonite recommends trying all 1,000 combinations or taking the bag to an authorized repair center. It is important to remember that if your bag has a TSA-approved keyhole, you should never attempt to find a consumer key to fit it, as those are strictly for airport security personnel to use during mandated baggage screenings.
