Get Your Safe’s Brand and Model, You’ll Need it

The first and most important thing is to determine the kind of safe you have. Why? It gives your local locksmith an idea of what they are looking at in terms of anti-theft measures. People place all sorts of items into safes it it’s these items that originally determined what kind of safe they chose to purchase. Safes not intended for expensive content are usually cheaply made. Safes meant to hold tens of thousands of dollars are usually, if you chose wisely, well made.

Typical Locations for Safe Make, Model, and Serial Number
You will need to find the brand, model and serial number of the safe so we can research it.

The brand is usually the easiest to find. Most of the time manufactures put this on the door of the safe. Many manufactures also put the serial number on the bottom corner of the door. Finding the model for the safe can be a bit trickier. Most manufactures are placing model numbers on the back of the safe. So if your safe is bolted down or too heavy to move, you may not be able to find it.

If you cannot find the model number, but were lucky enough to find the serial number of the safe, your next step is to call the manufacture of the safe and give them the serial number, they will tell you what model it is from that number.

When you can find the brand, model, and serial number of the safe, a locksmith can determine the correct drill points of the safe and get into the safe without irreparable damage.


If you cannot find the serial number, you will need to send pictures of the safe to your local locksmith. From the images and brand name we can usually get pretty close to the correct model number.

Using the Safe’s Key to Open a Safe When You Don’t Have the Combination

Opening Safe with Override Key
Does your safe have a key that could be used to open the safe instead of entering the code. Some safe manufactures, typically inexpensive cheap safes, provide this as a second method to get into the safe.

If there is a key over ride, your safe manufacture will often mail you the override key so you can get into your safe. Once in, you can often reset the electronic lock yourself. Or take the door to a locksmith shop and they can reset the electronic lock or safe dial for you.

If the safe manufacture won’t or can’t provide a key, the key overrides can still be extremely helpful because a local locksmith can often can gain access to the safe by picking the lock or making a key to it. If there is a number stamped near the keyhole of the key override, a locksmith should be able to get into the safe quickly, without damage. Note that on high-end, high security safes, there is usually a key that must be used WITH the combination. These are not bypass keys and can’t be used to get into the safe on their own.

Safe keys make it pretty easy to get into a safe without drilling the safe open so you can save a bit of money. Once open, a locksmith can reset the combination of the safe for you.

How to Get Into a Cheap Safe When You’ve Lost the Combination

Cheap Safes Cost More to Professionally Open. Better to Just Break In and Replace Them.
With the brand and model number, or often from a photo of the safe, the locksmith can determine the value of the safe itself. Here’s why you want that information. Safe crackers are expensive. To professional open a safe, and repair it, can easily exceed several hundred dollars.

If your safe cost less than $400, the best way to open the safe is to simply break in and buy a new safe.

How to Get a Safe’s Combination – Retrieve Combination or Override Code

You most likely will need to hire a locksmith in order to try these two things. Most safe manufactures will not provide this data over the phone for security reasons. Try the manufacture first to see if you get lucky. If they can’t help you, your local locksmith can.

Safe Dial Combination Retrieval

If the safe is a dial, and you were able to find the serial number, the locksmith will most likely will be able to retrieve the original combination to the safe. So long as the safe combination has never been changed, this will open the safe. The locksmith will then be able to set the safe combination to whatever numbers you desire. Or, if you’d like, the locksmith can replace the dial of the safe with an electronic safe lock.

Electronic Combination Override

If your safe has an electronic lock, the safe serial number or the serial number of the electronic safe lock itself, can be used to see if there is a master override code for the safe. Entering the override code will reset the electronic lock so that the locks default combination will work.

To perform these services at ACME Locksmith, or your local locksmith, we will need to go to the location of the safe and verify you are the owner of the property the safe is in. We will not attempt either of these two techniques to open the safe without this verification.




Drilling the Safe Open – Your Last Resort to Get Into an Expensive Safe

Professionally Opening a Safe via Drilling
As a last resort, your safe can be opened by a professional when the combination has been lost. With the model and serial number, the locksmith (aka safe cracker) should be able to get the drill points of the safe and this makes getting into the safe more affordable than if this information were not available. The locksmith will know exactly where to drill as not trigger any of the safe’s security measures.

Opening a safe via drilling requires we pull the existing lock off and drill in through the front of save to take out the components keeping the door closed.

If you have not been able to determine the model and serial number, a locksmith can still drill the safe to get in and repair it after it is drilled so that it functions like new but it may be more costly. Typically it a pilot hole will be drilled and the safe scoped to determine where the drill point is. Without a drill point, sometimes a security feature will be triggered on the safe, such as a re-locker, and more drilling will be required.

When opening a safe by drilling, the safe’s lock body is destroyed and the safe lock will need to be replaced. Additionally, a hole will be in the door of the safe. This hole is plugged with a steal rod and ground off flush. Because this hole is under the old safe dial / safe electronic lock, the repair will not be visible and the safe will not show any damage or repair.
