23 Distinct Types of Keys You Can Get on the Market

13 min read

Since 6000 years ago the locking system has been initiated by people in the ancient Babylonian and Egypt era. Even at that time, they already design various types of keys.

Of course, the materials used are also quite simple, such as wood or animal parts.

Over time, other nations also developed this system and increasingly create different types of keys for locks. The quality displayed is also getting better with more efficient use.

The following are some that we are familiar with today.

Primary Key to Open Everything

All locking systems are made based on the principle of uniqueness. None of the types of keys have the same shape, pattern, and curve.

However, there is one who does not apply this notion, namely the primary.

These types of keys are the most different because they intend to open multiple locks at once. Its function is as emergency access when the real one is lost, damaged, or unavailable for some reason.

Primary keys are usually not made in large quantities and used by important people, for example, the owner of a house or building.

But of course, you need special expertise to design it because you have to combine all the key-shapes in a building into one item.

As a valuable symbol of luxury, people impose fairly strict security on cars. It leads to a complicated locking system and involves many tools that are sometimes difficult to remember.

The following explanation will help a little to identify the key type for cars:

Traditional Key

When compared with the types of keys that are currently developing, the traditional seems old-fashioned. It is the most basic type commonly found on older cars.

There is no encoding system in it. Use it by putting it in the locks to open it.

The low level of security is also one reason why this model is unpopular right now. Traditional keys are easy to make and fake.

However, this locking system is still used to secure buildings, rooms, or other possible things.

Master Key

Besides the traditional type, master keys are also one of the early technologies in the locking system.

Old cars were equipped with this feature as prints when making copies and replacements. However, they are not for daily use.

If those sorts types of keys are missing, then it will be difficult to substitute. Apart from spending a lot of money, the car owner may have to replace the entire engine management system.

Because it is considered impractical, this method has begun to be unpopular.

Just a suggestion, if you buy an old car, make sure you do the double-checking to make sure the types of keys you get.

In addition, if you get the master key, make sure the system is working, and you also have backups.

Switchblade Key

There’s nothing special about these types of keys. It’s just that the switchblade model is unique as it is foldable like a penknife. These variants have a button that allows them to appear and sink.

The way to use it is standard as an ordinary key. Also, this system is considered safe because it will protect the main parts of a key from damage due to friction, fracture, or other things.

Transponder/Chip Key

Transponders, also known as chips, are the popular model today. This tool has a microchip that operates upon the wireless sign.

When the ignition code is correct, the car will start. Today, they are known as the most reliable types of keys.

Along with the sophisticated system that keeps thieves away, these tools are also not easily counterfeited.

The duplication and replacement of this key will be expensive. Even if the code is hacked successfully, the owner can easily replace it with a new one.

Mechanically Cut Key

Unfortunately, these types of keys have a low level of security. Its simple structure is easy to recreate. If you have a car with a mechanically cut model, be careful not to lose it or misuse it.

The laser-cut has many similarities to the mechanically cut model. However, these types of keys are preferable because of their higher accuracy and complexity. Hence, they also have a greater extent of protection.

Certain types of keys are known as the sidewinder too. The two sides of the lock have a unique cut pattern and ridges. Thus, the laser cut models become a unique unduplicatable tool in a locking system.

Smart Car Key

These types of keys are a technology that is one level more sophisticated than the transponder or chip model.

The basic concept is the same, namely using a signal-receiving microchip, but smart cars have undergone various improvements that make it even harder to fake them.

Apart from having a high degree of accuracy, the smart car key also allows the owner to open the lock from anywhere.

The unique code in it aims to minimize error code so that errors cannot occur.

Unfortunately, it is still very limited in number. The manufacturing and duplication process is also complicated and expensive.

However, these types of keys will be promising future technology to improve.

You should be familiar with the valet service that many car owners use when they come to a prestigious place.

No need to park the car yourself as you can hand over the car keys to the officers and they will help to park and retrieve them while you are away.

Unfortunately, this kind of system worries many people. Who can guarantee that the officer does not do anything forbidden in the car?

Fortunately, there is a valet key that will answer that anxiety.

Even though they provide access to open the door and start the engine, not everyone can get full access.

Other people won’t be able to open parts like trunks, boxes, or things that you think shouldn’t be opened just anywhere. Thus, you can calmly leave the car.

As the name suggests, these types of keys rely on dimples on their surface. This part has a crucial role as an opening tool. Generally, the cavities are conical in shape and will match those in the locks.

Dimple keys themselves are one of the most preferred choices for people. The reason is, it has a simple form and is very easy to use.

Locking systems with advanced technology do provide better security guarantees. However, those types of keys usually cost a lot of money and are therefore less economical.

But if you want a lower price, try this double or four-sided model.

Each lock has two or four teeth that will provide guaranteed safety to the building or object. The four-sided one has a higher level of locking than the double one.

In addition, the expense is considerably cheap than others.

The sophistication of technology has indeed led to various kinds of convenience. One clear evidence is the emergence of locking systems that rely on magnetic fields to open and close.

These types of keys do not involve electricity in their operation.

The use of a magnetic key is to put the push and pull parts together and then turn them. Besides, to increase security, you should enter a combination of numbers.

Besides buildings or cars, one particular item that also often needs a key is a diary that stores information and privacy.

Among the many types of keys, the digital system is perhaps the most sophisticated. Instead of using patterns, shapes, or curves, the lock and unlocked things use information that has been available on the computer.

Keycards are an example of a digital type, but some don’t use tools at all. Instead, the system will look at fingerprints, corneas, or other biometric information.

Thus, security is also more guaranteed because only certain people can access it.

Digital lock systems are popular in buildings that require a high level of security, for example, government buildings, laboratories, and so on. But of course, this security costs a lot of money.

After reading the above review, now you have more knowledge about how to identify a key based on its form and function. Thus, you can use it accordingly.

Besides, we can conclude that parts of a key have a great impact. Each safety medium in the locking system, except the primary-type, is designed to have different patterns, shapes, and curves to guarantee security.

The complexity of the locking system has led to many types of keys used by the public to date. In the future, there may still be more variants with different functions and purposes following the developments and demands of the times.
