There are several different ways to open a safe without a combination, including prying, cutting and drilling. A safe may need to be opened without the combination if there is a lock malfunction, a fire, a lost combination or a burglary attempt. Safe technicians, locksmiths and burglars alike may need to know how to open a safe without the combination.
Attempting to pry a safe open is one of the crudest methods, and it is one of the least effective. Successfully prying open a safe requires a great deal of time, energy and strength in order to work the door and the bolt work out of the door frame.
Cutting into a safe is done with either a saw or a torch. This method often results in a large mess and a lot of noise, and it requires an abundance of time. A majority of modern, high-security safes are built with a special composite barrier made from copper plate that slows down the effects of heat. Some safes contain tar in the barrier so that smoke is produced if a torch is used.
Safe technicians often drill into a safe to access it without a combination. This method is used if the safe has manipulation-resistant or electronic locks. The goal of drilling is to make a small hole so that a precision instrument can be inserted to gain access to the safe.
