The performance of cars depends solely on what ignites and commands other mechanical parts to start operating. At the center of it is the car key, often used to start the vehicle, which is why it is not surprising that these have undergone as many changes over time as the vehicles themselves have to improve their capabilities.
Currently, different car key types reflect the evolution of security and convenience mechanisms that have been incorporated over the years to make life easier for drivers around the world.
Most modern vehicles have an immobilizer system that uses coded keys; however, not all vehicles use the same type of ignition key.
In this article, we’ll tell you about the different types of car keys available on the market and their characteristics, so you can understand how each one works.
Types of car keys
The different types of keys available offer features that enhance vehicle security in various ways. Below is an explanation of each type:
1. Traditional keys
These types of car keys are used in older model vehicles, as they are among the first keys used in cars. They have a simple toothed key design and function only to start the car once the key is inserted and turned in the ignition lock.
Because of the simplicity of these key systems, these cars are easier for thieves to steal, because starting the car without a key is easy as it can be done simply by connecting a couple of wires. This process is called hot wiring.
Thanks to the detection of these problems in older systems, new ways of applying technology to vehicle security have emerged, leading to the development of more complex keys.
2. Transponder keys
Transponder keys feature more advanced technology than the keys mentioned previously. These keys contain a chip, also called a transponder, programmed with a code that the car must read to start when the key is inserted into the ignition.
Cars equipped with immobilizer systems use this type of key. The immobilizer system provides a higher level of security for vehicles because it’s impossible to start them without the key programmed with the corresponding code.
This system reduces the risk of theft because it’s difficult for thieves to start the car without the correct key, unlike traditional key cars. This is why this type of key is used in most modern cars.
Because these keys require programming a code that matches the immobilizer system, the coding requires professional assistance and specialized equipment to write the data to the key’s transponder. This requires devices such as key programmers.
If you have a car with this type of key and the immobilizer system is malfunctioning, it is advisable to consult professionals with automotive diagnostic equipment to determine what repairs your vehicle needs or whether you need new key programming.
3. Remote control keys
Remote key fobs, as their name suggests, are keys that can lock or unlock a car even when you’re not near it. They work via buttons that let you lock or unlock the vehicle remotely.
The design of these keys depends on the car model: some use a single device with the remote control built in, while others separate the remote from the key that starts the vehicle.
These types of keys can also have a transponder, making them convenient and easy to use while providing car security.
4. Card keys
These types of keys work similarly to remote-control keys but with a different design: they are shaped like a slim card that can be easily kept in a wallet or pocket, unlike conventional keys.
These types of keys also use a chip that allows the car to be opened and locked remotely.
The vehicle ignition works similarly to that of transponder keys: once the user is detected inside the car with the card key that includes the corresponding code, the system allows ignition via a button inside the car.
5. Keyless System: Hands-free keys
Vehicles with keyless entry are more modern and often higher-end models. The novelty of this type of key is that it’s not a key at all, but rather the absence of one. Cars equipped with this technology don’t require a device to start; simply approaching it will automatically unlock it.
Its ignition, as well as that of the key card, is activated by a button inside the vehicle, so the inconvenience of inserting and turning a key, even for some people struggles with a key stuck in the ignition, is now a thing of the past with cars equipped with this technology. It’s a system that prioritizes driver comfort and safety.
Extra for car owners
No matter which key you use or what car model you have, you will definitely need a keychain to hold your key. Especially if you are a car enthusiast, you want an automotive keychain that conveys your passion for cars.
It is important to be careful when choosing a keychain. A lightweight, minimal metal or non metal keychain is the perfect pick for every car enthusiast and car owner. You do not want a keychain that is too heavy and might damage your ignition, or bulky or made of pure metal, which could scratch your car dashboard.
The new moving 4-cylinder engine automotive keychain is designed with all these features in mind. It is lightweight and compact, crafted from carefully balanced materials to prevent unnecessary weight or scratches. Check it out now to get it shipped to you for free.
