It is a well-known fact that the master keys are something that many people seem to be fascinated by.
The fascination, we believe, is due to the absolutely confusing nature of the above-mentioned device.
And you are now probably asking yourself, how is one key opening two doors, but another key that opens one of those doors is not opening the other?
Is the key special?
Is it the reason for the internal mechanics of the lock?
Well, I have to warn you that there is some math involved in these answers.
Before you stop reading, and we may have already lost some people), nothing is too complicated.
At the lowest level of understanding, it is addition and subtraction, and at the highest level of knowledge, at least what is shown here, they are exponents.
Furthermore, it is not scary.
After reading this division, you should have already understood every master key system, from the most straightforward to the most complex.
With a fundamental understanding, one should be able to extrapolate potential improvements to system security.
Keys in a Master System
The fact is that without the master key, there is only one possible lock key.
This is the key to turning a simplistic lock into a key lock.
In some systems, this will be the key to the highest ranking.
In trade, the master key can also be abbreviated to “MK”.
When it comes to changing the key, it is easy to say that this key is also called a sub-master.
It will likely open one lock and only locks that are exactly the same.
The lock key will be opened using the master key and any key above that range.
Grand Master Key
It is a well-known fact that a grand master key is used to access multiple master key systems simultaneously.
This key will likely open each central system below it and the subsequent switch keys under those systems.
In conclusion, the key can be abbreviated to GMK.
Great Grand Master Key
It is a well-known fact that the great grand master key will likely open all the existing grand master key systems below it, the master key systems below them, and the change keys below them.
Theoretically said, this trend could continue until the locks become too complicated to function.
How Do the Master Keys Work?
Most critical key systems operate outside the primary needle lock.
Quick overview of how the basic needle padlock will work mainly in order to open the lock, and the pin, which consists of a driver pin and a pin, must be raised so that the two lie on opposite sides of the shear line.
Furthermore, it is a fact that a button increases the key pins within the lock.
These key pins are of various sizes.
The driver pins will likely be of universal size.
Therefore, the key should have a suitable set of grooves to raise the key pins to their correct height.
It’s too simplistic, but if you want to know more about the specifics, you can check out the house lock section on our website.
With this understanding, it will be easier to understand the addition of a master key system.
All it takes to turn any standard Master Key needle system is to add a master needle, aka primary needle, which is between the driver and the needle.
The central needle is small in the shape of a hockey puck.
Once in place, the chimney will have two shear lines.
Furthermore, the needle shear line with the main wafer needle below or above the line is a fact.
When it comes to key takeaways, it is easy to say that a master key system allows two or more keys to be unlocked.
Major key systems often use roller locks.
The main buffer locks use the main wafer or the pin between the key and the driver pin itself.
Most large institutions absolutely do not want their employees to carry large quantities of keys.
Similarly, these institutions would like to limit the approach based on the institution’s relationship and responsibility.
The main key system will allow different levels of restricted access.
Once the master key system is completed, there may be an access level for postgraduate study.
In the example of a property manager, the tenant’s key will work on the lock but not on the neighbor.
Yet, the property manager will have one key that works for both locks.
This can work to create several possible keys.
Supposing there are five chambers in the lock and five active needle piles.
If each of those stacks has the leading wafer, each chamber will have two possible shear lines.
It is 2x2x2x2x2, or two to the fifth power (2^5), which is equal to a total of 32 possible suitable keys.
Of those 32 above-mentioned possible keys, only two types of keys need to be made necessarily.
One will be for the person who has access to what locks the lock, and the other will be for the person who has access to what each lock provides on the site.
The master keys will be able to open more locks.
The more significant the difference between the master key and the shift key, the larger domains will need.
The more the master is a wafer, the more possible buttons can open the lock.
It is a well-known fact that convenience often reduces security.
The more convenient something is for the actual user, the easier it is to beat, such as some of these locks.
The primary locking locks are an excellent example of this.
A master key system will likely make your locks vulnerable to several types of attacks.
Exploration keys are used to decode master systems with just the change key and the lock that opens.
For purposes of doing this, the first key in the exploration cycle will have a zero cut (no cross-section, as if this groove were empty) of what would be the groove closest to the shoulder of the key.
Knowing what type of key it is, you can add the key codes and cut the zero cut to one.
Try that key.
The moment you have descended to the groove’s most profound depth, you need to understand how to attach the first section to the wrench.
In case there is only one depth that turns the lock, then there is no leading wafer.
If the lock is open at two depths, then there is a first needle holder’s first table.
There may be more than one shear line if there are more wafers or pins.
The following exploration key holds the depth closest to the shoulder at the sole working center or a depth not found in the original key.
Let the next intersection be at zero, then start the process again.
This process will be repeated with each biting rhythm.
Each time you make another research key, you will retain the unique depth or depth of work that your original key did not have.
To save time in the research process, you can assume that no larger areas change the depth value by a factor or greater or less than the depth of your work key.
Main wires with differential depth are often not used because they can clog the lock’s inner parts.
The lock you will probably be working on may have wires of one depth, but assuming it does not, it will potentially save you time.
When you have a key that works in your lock, which has as many different reductions as possible, you will likely know all the possible keys that will work in your lock.
It would be best if you created a key for each occasion.
To find the number of keys you need, use formula two for the power of n, aka n = number of chambers with the main wafer, i.e., the lock with the main wafer in 3 compartments has eight possible keys.
The two may vary if there is more than one main chamber in the chamber.
Furthermore, more master keys are used to make more complicated systems, such as the Grand Master key and the Great Grand Master key.
If the system is Grand Master, Great Grand Master, or even higher, you will increase the number of available key codes accordingly.
For each additional main wafer, you must add the shear line in the chamber.
Another way you can reduce the decoding time is to do some research on the lock.
If the lock is Kwikset, then there will be a maximum adjacent cutting specification, aka MACS, of four.
This means that the intersection of the two sides must not exceed a difference of four.
For example, a key can have 2, 4, 5, 2, 6 bites.
The variation between 2 and 4 is 2; the difference between 4 and 5 is, or even the difference between 5 and 2 is 3; the difference between 2 and 6 is 4.
If the 4th groove were one, then the difference would be five between forest 4 and 5.
That would disrupt MAKS. Since this will never happen, when decoding for this key, you would know that there is no possible key with biting 2, 4, 5, 1, 6.
So, out of the possible 32 biting combinations you may need to try, there may be some that you can retrieve from the list before you do.
With a few keyboards and a lock, you can decode your system’s master key.
You can assume that there is no difference in the groove greater or less than the track of your original key.
You can easily ignore biting keys that break MACS.
Adding headbands to your lock will jeopardize your safety, with a few exceptions.
However, as long as the main wafer creates a secondary and functional shear line, you will compromise safety.
Basically, there are two different ways to choose each chamber.
There are 32 various ways to select the lock in a five-chamber lock with the leading wafer in each.
This increase in lifting weakness will make the lock more susceptible to missiles as a bypass method.
Because any amateur can jump into the ridge, the number of people who can dramatically open your locks increases.
In the security industry itself, the amount of skill required to beat your defense is directly correlated with deterrence.
Although the vulnerability of your selection system can increase dramatically, you need to assess the risk.
Are harvest attacks common in your area or even in the industry?
You will also need to measure how much the master key system will help you with your security regarding key control and personal convenience.
It is easier to assemble locks with the master keys.
Locks that are easier to assemble have a more significant number of thieves that can defeat them.
The likelihood of a threat must measure this vulnerability.
Making a Master Key System
As discussed earlier, the master key system will open a lock using at least two keys.
In case you are looking to make a master key or master key system, the first step will be to assemble two buttons with the same style.
The moment you have these keys, you will need to decode their depth.
You can easily do this most quickly with a key gauge.
In case you do not have a key gauge, you will need to be creative with the tools you have.
In case you are a locksmith or have the required tools and time to make an entirely new key with the exact cuts you want, there is no need to use two existing keys.
You can additionally buy an attachment kit if you’re going to do this more often.
Whether you are making keys or using existing ones, note the current or intended groove depths.
We are willing to say that these are our keys that we find helpful in this situation for our theoretical example, starting with the first key, equivalent to 2,4,5,2,6 and with the second key, equal to 4, 2, 5 4, 6.
The next thing you will have to do is assemble a lock that matches the key type.
For our example, these keys will be from the model of Kwikset.
You should also be able to turn the lock on again before accessing the pins.
Now we start creating the master system with the following 10 phases.
The first one is to vertically compare groove depths (2 and 4, as well as 4 and 2; 5 and 5; 6 and 6, and finally 2 and 4) and mark the most lightweight one in a set.
Here we can mention the differences in the key one, which is consisting of 2, 4, 5, 2, 6, and key two, which is equal to 4, 2, 5, 4, 6.
The next two steps you will need to take is to write down all the lowest depths in the correct order.
In this case, this would be 2, 2, 5, 2, 6.
Of course, if the depth is repeated, it is the lowest depth.
And the second step is that you will have to subtract the lowest number from the vertically adjacent number.
Consequently, you will have to write down the numbers in proper order, for example, 2, 2, 0, 2, 0.
Furthermore, the list of numbers from step 2 will be the bottom pin, and the list of numbers from step 4 will be the values for the leading wafer.
As an example here, we can mention the lower pins: 2, 2, 5, 2, 6, and the main wafer: 2, 2 and without main wafer, 2, without main wafer.
Bottom pins: 0.195, 0.195, 0.285 0.195, 0.265.
The next thing you need to do is open the lock and remove the existing pins.
It is a well-known fact that you can store the pins for any chamber in which no main wafer has been added.
For example, these will be chambers 3 and 5.
Insert the pins into their respective chambers, starting with the lower pins, then add the appropriate wafer.
Install the lock again. And finally, you will have to try both keys.
The moment you have a working lock, you can open it with two keys.
One key can be assigned as the master key and the other as the change key.
To continue building the master key system, repeat this process with your master key, third key, and second lock.
Try to stay away from using major wards number one.
As mentioned earlier, the smaller the main wafer, the higher the risk of damaging the lock is, which means that you will have to call a locksmith to repair the damaged locks.
When it comes to seizing keys, we can easily say that to make a master key system, and you need locks and keys that are the same and models.
Start with one lock and two keys and repeat the procedure until you get the locks’ desired number.
Use large compartments with a value of 2 or even greater.
There are additional security measures designed to maintain your home’s security, which can be added to the master system.
These precautions will make selection and decoding challenging but not impossible.
Adding sidebars and key active elements will make the research much more complicated.
The primary system does not even need to use a lock for adjustment.
You can master retaining disc locks to serve as a more sophisticated and secure means of protection.
As protections are added, the lock will likely have to become more complex.
Whenever you add security, make sure you understand the complexity of the system.
Our general rule is that you should not do your own thing if you can not separate and assemble it.
If you are creating ideas for your own additional security ideas, we would definitely recommend exploring your idea.
In the rare case that someone does not have your idea, try to find a device that works similarly or in a more fundamental way than your opinion.
This is the mechanism that needs to be deconstructed and completely understood.
Test all additional security before using it in your operational security.
When it comes to word about the key takeaways, you could easily say that the additional security will make the lock challenging to select and decode.
Sidebars or types of locks that use sidebars can increase the safety of the lock.
Understand the mechanisms if you install them.
The Bottom Line
From all that we have said and all that this guide has shown us, we can easily conclude that the main key system allows two or more keys to open a single lock.
To make a master key system, you will need to have locks and keys that are the same brands and models and a way to return those locks.
Basic tablet needle headlights use the leading wafer or the pin between the key and the driver pin.
Although these systems often use roller locks, they can use different locks for different security levels.
The main selling point of key locks is limiting the number of keys needed to open multiple locks.
These systems can become quite complicated with the introduction of large master keys and large master keys.
The more mast nets, the more buttons can open the lock as the number of shear lines increases.
The main key systems are very susceptible to harvesting and decoding.
The easier it is to assemble the lock, the more thieves can steal from you.
By completing a risk assessment, you will likely be given a deeper understanding of whether your threats and vulnerabilities should affect you.
At all times, try to do everything for your safety, evaluate the strengths and weaknesses.
Furthermore, there is no need to break down door locks, aka a vital part of home security, for the purpose of saving a few bucks.
It is essential to note that you should not use any of this information for any criminal or illegal activities.
Therefore, we can entirely say that this article is for educational purposes only.
