Whatever it's called, this feature allows you to fire up your car's engine without fumbling for a key in your pocket or purse.

The keyless ignition system was first introduced on production cars in the late 1990s and early 2000s. Being expensive and exclusive like high-tech features, the keyless ignition system was initially available only on luxury cars. The first mass-produced car that had the keyless ignition system was the Mercedes-Benz S-Class, followed by models from Acura, Lexus, Cadillac, and Rolls-Royce.

How Keyless Ignition System Works

The innovative keyless ignition system redefines the meaning of convenience. The technology is more like a Bluetooth connection- the other device automatically gets connected with the Bluetooth enabled device. The keyless ignition comes with a fob that can be kept in your pocket, purse, bag, or anywhere, which is close to the receiver inside the car. The fob sends out a low-frequency signal to the car's system, thereby ensuring that the right signal has been sent. You can now push the button on the dashboard or console to start the engine.

Just like turning on the engine, switching it off is equally simper. All you need to do is press the start/stop button. Moreover, in addition to keyless ignition, ​several cars offer keyless entry that lets you enter your vehicle without inserting a key or hitting a button on the fob.

There's no doubt that keyless ignition has become quite popular, and is readily available, even on affordable cars. On the contrary, the system isn't an automotive necessity like power windows and door locks. The selling point of this system is luxury and its convenience factor, especially for the drivers with arthritis or other disabilities that deter their ability to grip and turn a key.


Optimum convenience and security are the pros of a keyless system. It is difficult for a potential thief to start or steal your car until and unless he has the key fob. Also, having a key fob lessens the chance of key misplacement or having to search the depths of your pockets or purse for the keys. Few systems use rolling codes for enhanced security.


Everything has both good and bad sides. A keyless ignition system is not different. The downside of this system is that its components eventually break or wear out over time. To use the system again, you will have to replace it or get it repaired, which means spending a considerable amount of money. Apart from it, the chances of the engine being switched on is high, in case you leave the key fob in or around the car. To stay safe, you should be attentive where your key fob is.

No matter how advanced the technology gets, there's always a loophole or two that arises threat. In order to keep your car safe, you should insure your vehicle with a car insurance policy. A car insurance policy covers your car in the events of accidents, thefts, natural calamities & more.
