All about Keyless Ignition
The technological advancements and higher convenience demand have carved the automotive standards. The engine push start button is one of them. The conventional key ignition systems are replaced, now you can operate the engine with a single push.
In the following paragraphs, we will elaborate on the keyless ignition, its working, types and more.
Keyless Ignition System in Cars
The keyless ignition system is a modern ignition system that utilises electronic authentication for entering or starting the car. Electronic authentication can be controlled by a handheld device known as a key fob. The whole purpose of introducing this ignition system was to increase the security of vehicles and convenience to the drivers. The first of its kind was introduced in the Mercedes-Benz S-Class in 1997 and became automotive standards since then. There are multiple types of electronic authentication used in keyless ignitions. Let’s take a look at these types.
Types of Keyless Entry
The keyless ignition system can vary from manufacturer to manufacturer. The working of these keyless ignition systems is more or less similar. See the following common type of ignition switch.
- Push-Button Start: The push start button in cars is the most common keyless ignition type. It uses a key fob to disarm and start the car. The car will only start by pressing the engine start button, with the key fob in the range.
- Rocker-Type: The rocker switches are spring-loaded switches that need to be flipped for turning the engine on and off.
- Rotary Switch: These are the conventional ignition systems that need to be rotated for turning the engine on and off.
- Smart Key: It is the latest form of the key fob. The ignition system can automatically detect key fobs within the 5 to 10 feet range and exempt commands for disarming. The drivers can directly enter the vehicle and start it. Moreover, smart keys can also be used for a number of other operations like running a climate control system remotely.
How Keyless Ignition System Works
A key fob also known as the smart key is the major element in keyless ignition systems. The system may vary from model to model but the significance of the fob is similar. The keyless system works on the basis of radio signals. The key fob is a radio transmitter that amplifies low-frequency signals to the car’s ignition. The ignition will unlock the car once the car computer recognizes the radio signal.
However, to start the engine driver and key fob must be inside the car. The antennas around the car use a comparative calculation to identify the position of the driver and key fob within the car. When the push start button is pressed, the receiver disables the immobiliser, the engine circuit is powered and the engine is started.
Despite all this, to increase the security measure, the car must be in parking mode and the brake pedal should be pressed. This radio signal ID or rollover security code of every fob is unique and thus, no other fob can disarm the car. Though this modern ignition system is well-equipped there are some pros and cons of this system.
Pros and Cons of Keyless Ignition
The introduction of keyless ignition was the milestone towards the modern car concept. It surely replaces all the conventional ignition switch problems, but it also has some cons. See the following list of keyless ignition issues.
- Optimum convenience to the drivers is the utmost benefit of keyless ignitions.
- The unique security code of key fob and ignition reduces car theft.
- A number of driver comfort features can be controlled from a distance.
- It reduces car accidents, as it will not start the engine until brake pedals are pressed.
- The radio frequencies transmission by the key fob is traceable and can be used for hacking car systems.
- Drivers can leave engine idling that can produce carbon monoxide which is poisonous.
- The system is completely inoperational without the fob.
Troubleshooting Keyless Ignition
Multiple reasons lead to keyless ignition switch malfunctioning. The most common one is the dead battery of the key fob. In this case, place the key fob on the engine push start button and press it. Some vehicles of Audi and Toyota have an opening in the dashboard to insert the key fob for starting the vehicle immediately. If both the options fail to start the engine, it is recommended to immediately concern a professional for further diagnosis.
Cost of Keyless Ignition Replacement
As mentioned above, the key fob and keyless ignition work in pairs. Therefore, it is recommended to concern the authorised company dealer for its replacement. However, you can also purchase it from the market, but it requires reprogramming. The starting price of the key fob is AED 120 and the ignition switch is AED 110. Whereas, the cost of reprogramming starts at AED 250.
This was all about keyless ignition in modern cars. This modern ignition system is effective in reducing car theft and is also convenient for drivers. If you are still driving the car with a conventional ignition switch, it is time to upgrade it. Browse through, these used cars for sale in the UAE, and avail yourself from keyless ignition.
