For security reasons our locks cannot be opened or reset if the current combination is unknown. As there is no option to open the lock without the current combination also our customer service employees cannot provide you with a quicker solution to open your suitcase. The most reliable method to find out the combination of the lock is to try out all combinations from 0-0-0 to 9-9-9. It is recommended to perform this process in a structured manner and always increase one digit e.g. 0-0-0, 0-0-1, 0-0-2. Usually, it takes 30-40 minutes to find the correct combination. If the lock cannot be opened after trying out all possible combinations the lock has to be opened by breaking the locking mechanism. Please read the information below prior to proceeding with this step. We recommend setting a new lock combination after the lock has been opened (using the instructions above) and noting down the code in a safe place. Other methods to find the combination can be found online but largely depend on individual skill or the way a specific lock is constructed. As these methods are not always successful we do not recommend to use these methods. Another option is to break the locking mechanism. While this method may allow you to open the suitcase more quickly it will permanently damage the lock requiring it to be replaced. We would strongly recommend to contact our customer service in advance to ensure that the required spare parts are available. Please note that if you have forgotten the combination the cost of a replacement lock and the shipping cost are not covered by our warranty.
