If you've located a suitcase trunk that you hadn't seen in years or if you lost the key to your luggage on your flight, you are left with the dilemma of opening a locked suitcase trunk without the key. Many luggage manufacturers are happy to provide you with replacement keys upon request. However, because of the length of time it takes for such companies to ship keys, you may decide that it is more worth your time to simply try to open the suitcase trunk without it.
Look for the screws on the side of your suitcase trunk's lock. These are typically tiny Phillips screws. Carefully remove the Phillips screws with a screwdriver. Place the screws in a safe location, such as your pocket.
Slide the lock up and down on the suitcase trunk a few times to see if it comes off your trunk easily. If it does not, use a flathead screwdriver to pry the lock off the suitcase trunk. Set the lock aside and open your suitcase trunk.
Use a flathead screwdriver to pry open the locked suitcase trunk, if there are no screws on the lock or if you are still unable to open the trunk after removing the lock. Use force to pry open the trunk.
Use a pocket knife on your locked suitcase trunk, if the other options don't work and if you don't intend to use the trunk again. Stab the knife into the trunk carefully and forcefully. Do this near an edge in case something valuable is inside. Once you have punctured the trunk, carve your way around its outer shell to access the contents.
