Keeping important documents, cash and other valuable items in a combination safe is a smart idea in case of burglary, fire or natural disaster, but what happens when you can’t get the safe open to access those important things?

Despite the numerous types of modern locking devices for safes – including electronic keypads and biometric fingerprint readers – traditional combination locks continue to be a popular way to keep cash and valuables secure. They are effective and difficult to crack, but exactly because they’re effective, trying to open a safe when the combination has been forgotten or isn’t working can prove to be difficult and time-consuming.

It looks so easy to crack a safe in the movies; just put your ear to it and turn the dial slowly. Good luck using this method! In reality, whether you forgot the combination or are unable to open the safe because of mechanical problems, it’s best to call a trusted locksmith to avoid damaging the lock and making it more difficult to open or repair. There are a few techniques that a professional locksmith can employ to troubleshoot the problem and get the safe open. Learn about the reasons why a safe may not open and how a locksmith can work around these challenges.

Why is the Combination Safe Not Opening?

When a homeowner or business manager has problems opening a combination safe it can be stressful, but don’t panic or begin taking drastic measures that could damage the lock mechanism. The first step to getting the safe open is to identify the problem.

Forgotten Combination

If you simply can’t remember the combination for the safe, take a break. It may seem like useless advice, but sometimes, if you divert your attention to another task for a short period, the thing you are trying to remember will suddenly return. You should also check with anyone who has access to the safe to be sure they have not changed the combination.

When you have verified that the combination hasn’t been altered from the one it had when originally purchased, there may be a quick fix to the problem. Find the serial number, which is usually on the side or on the back panel of the safe, and contact the manufacturer. There is a good chance that they will be able to recover the combination for you.

If this isn’t; possible, a skillful locksmith should be able to manipulate the lock. Thanks to Hollywood films, this is the technique that we often associate with cracking safes. By listening for specific sounds and feeling the vibrations that a dial makes as it’s turned, a locksmith can find the right combination to unlock the safe. This is the best way to resolve the problem as it doesn’t harm the integrity of the safe and can usually be completed in less than an hour.

Safe Not Opening With the Correct Combination

If you are sure the combination you’re using to open the safe is correct, yet the door is not opening, this may indicate a problem with the lever or hinges rather than an issue with the locking mechanism. Often the first method for opening the safe is to pry the door. Applying grease to the hinges may increase success as you apply pressure and try to pry the door and bolt work out of the safe’s frame.

This is generally the least effective way to open a combination safe and should be used with caution as there is a high risk of damaging the safe beyond repair.
