Many cars come with a feature that gets rid of this hassle and makes getting in and out of your car much simpler. As the name implies, keyless entry allows you to approach your car and have it automatically unlock without having to go through your pocket for your keys. When you enter your car, keyless start will start it with the touch of a button as well—no need to turn the key in the ignition. How does it all operate though?

We describe the operation of keyless entry and keyless start systems and discuss whether you ought to install them in your next vehicle.

How Do Keyless Entry And Keyless Start System Function?

Keyless ignition is used in cars with keyless entry and keyless start. While the systems vary from one model to the next, they always use key fobs in place of the conventional metal key. The computer system of the car must be able to communicate with the fob inside the vehicle for the driver to start the vehicle by merely pressing a button.

Essentially a transmitter, the key fob transmits a low-frequency signal to the vehicle. Once the fob is inside the car and you press the button, the car’s receiver detects the signal and transfers power to start the engine. This ID signal is specific to that vehicle.

How Do Keyless Entry And Keyless Start System Function?

Keyless entry was introduced to increase convenience while reducing auto thefts as well. It is harder to steal your automobile because the vehicle will only accept the signal from that specific fob. The automobile won’t start unless it’s in park and the driver’s foot is on the brake as a safety precaution.

While pressing that button, which is frequently incorporated into the dashboard’s contemporary, cockpit-like appearance, has undeniably cool factor, keyless start systems have also come under fire from industry watchdogs, leading automakers to include new safety precautions.

The Operation Of Keyless Entry And Keyless Start

Both keyless entry and keyless start systems rely on radio waves that the automobile itself emits. The sensor in your keyfob detects these radio waves.

If your vehicle is equipped with keyless entry, placing your hand on the door handle (or pressing a button installed on the handle) sends out a signal, and if it detects the keys in your pocket, the door will unlock. The car can also detect that the key is missing after you’ve shut off the engine, closed the doors, and walked away, at which point it will automatically lock. If you routinely forget to lock your car, this may come in helpful.

The Operation Of Keyless Entry And Keyless Start

When it comes to keyless start systems, the idea is the same. The signal is activated by pressing the Start/Stop button on the automobile, and the vehicle will start if the key fob is nearby. Be aware that certain vehicles may only have keyless entry or keyless start.

Some cars have a hands-free tailgate for extra convenience while carrying things. These systems frequently use a sensor that is located below the rear bumper and allows the boot to be unlocked and opened with only a simple foot wave. You must still have your key in your pocket for this, of course.

Some vehicles, however, eliminate the requirement for a physical key by utilizing apps or data on your phone. Your phone can be unlocked on many high-end models by merely touching it against the door or B-pillar.

Pros And Cons Of Keyless Entry And Keyless Start In Cars

Adopting keyless entry and keyless start cars has advantages and disadvantages, just as implementing any new technology. Push button automobiles originally came in 1912 when Cadillac developed an electric keyless starter to replace the hazardous and difficult-to-use hand crank. However, the most recent model didn’t exist until the early 2000s. The start buttons, which were normally found on the floor or dashboard, were eventually replaced by keys.

Pros And Cons Of Keyless Entry And Keyless Start In Cars

Of course, technology is what makes the current keyless entry and keyless start different. Although that makes it more sophisticated and simple to operate, it is also the reason for some drivers’ and industry observers’ concerns. Arguments in favor of and against keyless starters include the following:

The Pros:

  • Because the car’s sensors talk directly to the fob while locking, unlocking, and starting the vehicle, the smart key can stay in the driver’s pocket or handbag.
  • The technology now makes it possible for auto owners to start their vehicles remotely, which is a convenient way to warm up a vehicle that is locked and parked in a driveway.
  • It is nearly impossible to lock your keys inside your automobile because the technology will identify if the key is inside.

The Cons:

  • Replacement costs for lost fobs are substantially higher than for regular keys.
  • Because some drivers haven’t received the correct instruction on how to switch off push-button ignition automobiles, they may forget to do so and leave the car running or put it in “park” before stepping out.
  • Since there is now no industry standardization, the functionality of the fobs varies from car to automobile.
  • The driver must be able to find and utilize the hard key that the manufacturer has concealed in the fob in order to disable the system in the event that the battery dies, or else they must call for roadside assistance.

Do Keyless Entry And Keyless Start Make Sense?

Keyless entry and keyless start systems are useful but not absolutely necessary. Although they make getting into and starting your car lot easier, these kinds of systems can have a ton of issues.

To begin with, it may be incredibly challenging to enter or start your car if the battery in your key fob dies. There is always a chance of getting stranded, even though many cars have the capacity to alert you of a low car key battery and others have backup ways to start the car.

The growth in car theft due to keyless entry is another issue. Thieves can now take advantage of the technology by simulating your key’s signal to unlock the vehicle. Although there are techniques to prevent this, the greater likelihood of theft may worry some people.


There are positives and negatives to keyless entry and keyless start systems, like with other technology and automotive industry improvements. But as they become the norm in the industry, it’s critical that every driver understand how to utilize them effectively.
