Code keys for safes

Code keys for safes

Many locks are stamped with a key code number but key codes alone are of little use. Extra information is usually needed to cut a key to code. A call to cut keys for room safes in a hotel was one such call that extra information was needed.  With no code information available these code keys needed a different approach.

Often a brand name of a safe, the make and model of a car or brand of furniture is also required to cut a key to code. The brand of the hotel room safes were an after market obscure brand that had no link to the locks that were fitted to the safes. The safes locks were all marked with a four number code between 1000 and 6000. The code numbers were a bit of a give away as to their meaning. The numbers seemed to be a direct code. A direct code is a code number that is also the cuts of the key. Such as 5226.

As there were quite a few safes to cut keys to, being able to cut them to the code number would save time and money for the hotel owner. The problem with these safes was that there was no reference to the space and depth dimensions of the keys. If you do not know accurately the space and depth of the keys, then cutting keys accurately is not possible.

In order to cut the keys to code, one of the locks was removed from the safe. The lock was then taken apart carefully, not to disturb the combination of the lock pins.

Once the lock was apart, the key dimensions were deciphered and a code card made up for a code machine. This is a fairly old code machine that is used in one of our mobile locksmith vehicles. This code machine is a punch machine and uses no electricity. It is perfect for use on a job site to cut keys to code.

Once the code card was created, the keys could easily be cut to the code numbers on the front of the locks.

Electronic safe lock vulnerability

Electronic safe lock vulnerability

You would be hard pressed finding a new safe or vault these days that does not have an electronic keypad lock. Electronic safe locks have almost completely replaced mechanical locks. The electronic locks are fast to open, easy to change the combination on, have options for delayed opening and a lot more user friendly then the older style combination locks where you spin a dial to the correct numbers.

electronic or mechanical safe lockThe old fashioned mechanical dial up safe lock made by manufacturers such as Sargent and Greenleaf had been used on safes for many years. Even the most basic 3 wheel safe lock gave a high level of security to safes. Safe dialers and manipulation techniques did give a way to open these mechanical locks but it took time. Safe dialers had to be hooked up for days in many cases to work out a safe combination.

Electronic safe locks are all mass produced and every model is pretty much identical to the next. If you want to break into a safes with an electronic lock, you just need to find a vulnerability with one safe lock. If you can find a way to open one then you can open every safe with that particular lock.

Well this is exactly what has happened. Electronic safe locks made by major manufacturers have been found to have flaws which can be exploited rather simply. By probing the keypad or battery wires connected to the safe it is possible to examine the processes which happen inside the processor chip of the lock. The processes cause electronic fluctuations which can be examined using an oscilloscope or specially designed circuit. It is possible to determine the correct keypress of a safe lock as opposed to the wrong keypress. As each process inside the chip is perfectly timed, any variation can be measured.

You can make a tool to break into these safes very easily. As they are electronic locks the tool can be used in a matter of seconds. A bypass of an electronic safe lock requires little skill and there is no barrier to opening the safe, once you have a bypass tool.

To make the matter even worse, there is no sign of forced entry when using these bypass tools. You could just be faced with an empty safe, next time you open the door.

This newly found vulnerability leaves almost every electronically operated safe very insecure.

While I am not going into detail here about which brands are affected, I would like to assure you this is a very widespread problem and measures should be taken if you are storing anything valuable in a safe secured by any type of electronic lock.

If your safe has an additional mechanical key lock, I would suggest always locking the key lock for added security.

5 ways to open a safe

5 ways to open a safe

If you have a safe that is locked and cant be opened then there are a few things that you can try to open the safe yourself.

Safe for Security documents

Security Safe

1 Check Batteries

If the safe is battery powered, then the batteries are the first think I would check. Most safes have a removeable cover or a removeable combination pad where the batteries are kept. Replacing the batteries in most safes does not affect the memory. If the dial is removable, be careful not to pull any wires as this could cause other problems. It is best to use alkaline batteries for most safe locks.


2 Bag caught in door

A money bag or other item can get caught in the door of a safe. If your safe is very full, there is a higher probability of this happening. If the safe door was hard to close the last time you used it this could give a hint to this problem.
Putting pressure on the door or jiggling the door back and forth while trying to open the door is worth a shot. The bag or stuck item will be putting extra force on the door and lock and might not easily be overcome by extra pressure.


3 Cant dial up the safe

If the safe has a combination dial and you just cant dial it open then it is possible there is a malfunction in the lock. Combination locks are precise mechanical devices that will not operate correctly without regular service.

Sometimes the combination wheels be the problem. They can spin sometimes over spin or get stuck. Try dialing the combination very slow. This can stop the over spin of the combination wheels. Also try dialing the combination fast, or with a bit of a snap. This can help if a combination wheel is stuck. Also try dialing the combination a little off the number. Just half a number to the side can be enough to allow the safe to open.


4 Stuck or broken boltwork.

The boltwork in a safe can sometimes get bent or stuck. Especially if the door is slammed with the boltwork in the locked position. If jiggling the door or adding pressure to the door does not work, try giving the door a tap with a rubber mallet. This jolt can be enough to get the door open. Give the safe a tap on the sides. Never hit the lock itself!


Key Override.

Many document safes have a key override. The key is usually under a cover on the front of the safe. Many people do not even realise their safe has a key override but it can be very important if there is a malfunction in your document safe. Just as long as the keys are not kept inside the safe itself!T


These are all basic steps that might save you from calling a locksmith to open your safe or vault.  If these fail to open your safe or you have lost the keys or combination then it might be time to consult your locksmith.  24 Hour Locksmiths Brisbane are always available to consult on your safe or vault problems.
