If you have forgotten the safe’s combination, first you need to find out which type of safe you have in order to use appropriate measures to be able to reset the code, recover it and unlock the safe. It is also good to have this information when you call the safe company.
After knowing the type of safe, you need to determine whether the safe has a key override that you can use in this case. If you don’t have the override key, you can use the change key which allows you to change the combination and gain access to your safe.
If you have tried all the above and the safe is still locked, find a locksmith and give them all the information about your safe including the brand, model and the type of the safe, just so that they have enough information to open your safe.
