If you lose your combinations to a safe, it can be a very daunting task to have it opened. There are right ways and wrong ways to open a safe and the technique used is going to be decided on by how much the safe is worth. To open a safe correctly, it can be time consuming, but the safe can be repaired and operational when all is said and done. If its a very cheap safe however, it may not be worth the price to open it correctly. At that point, the incorrect way (hammer and a crowbar) may be the best rout. It may not be pretty, but for the easier, cheaper safes, it may be better to just break it open and replace it.
