How Does a Car Remote Keyless System Work?

We’re living in an era of exciting technological advances — and cars designed for the mass market aren’t being left behind! Car remote keyless systems are becoming increasingly common, making starting your car with the push of a button a reality. How do these systems work? Are keyless systems more secure? Above all, should you want a keyless system next time you buy a vehicle?

How Do Keyless Entry and Ignition Systems Work?

Paul Lipschultz, who worked in the automotive security industry, patented the first remote keyless entry system in 1981. This early keyless system was made possible using infrared technology. Over time, this same idea evolved into the keyless systems in many cars and buildings. Modern keyless entry systems usually use radio waves to unlock doors and start the engine.

Instead of a traditional metal key, drivers have key fobs that interact with the vehicle’s systems. This system can be used to lock and unlock car doors, and can also allow for keyless ignition. Instead of turning a key to start the car, these keyless ignition systems invite drivers to press a button, flick a switch, or rotate a dial.

Once only used for luxury vehicles, keyless entry and remote start ignition systems are now so common that over half of the new cars sold today allow for keyless entry and ignition.

Are Cars with Keyless Entry and Ignition Systems More Secure?

Keyless entry and ignition systems have come a long way over the years. Early infrared systems could be hacked by tricking cars into recognizing different fobs. However, modern keyless car key systems are much more secure. Only dealerships can program these systems, so car thieves have a much harder time gaining control of the vehicle.

What Other Advantages Do Car Remote Keyless Systems Have?

Unlocking your car with the click of a button is no longer a gimmick — keyless entry systems have been popular for quite a while now. Keyless ignition remains more of a novelty. The main advantage is that these systems allow drivers to start their cars without needing to look around for their keys. The car will start as long as the key fob is within the vehicle.

Many systems are even designed to prevent drivers from locking their cars while the key is in the vehicle, which saves them a lot of trouble.

Do Keyless Ignition Systems Come with Any Risks?

Keyless ignition systems are now secure and convenient, not to mention nifty. What’s not to like? Unfortunately, car remote keyless systems do have challenges, as well.

Because a keyless ignition system means you don’t need to turn the ignition off to gain access to your key, some people have forgotten to shut the engine off and left their cars running. While rare, this can sometimes lead to carbon monoxide poisoning as running cars are left in the garage.

Drivers have the responsibility of developing a system to ensure the car is off and put in park before they go about their lives. Those who are used to using metal keys may find this transition quite tricky, though it is possible.
