In this digitally dominated world, savvy drivers are looking for innovative and technologically advanced vehicles. Technology can make a driver’s experience behind the wheel safer and more seamless. The smart key is one of the most stellar technology features you can find with new cars.

How Does a Smart Key Work?

The smart key is an integral part of the key fob that comes along with a vehicle. Even when the key fob is in the driver’s pocket, it can still unlock, lock, or start a vehicle. All thanks to the antennas in the car’s bodywork and the radio pulse generator in the key.

The radio waves of the key communicate with the vehicle to perform these magical tasks. Some smart key systems work when a door handle or trunk release button is pressed or a sensor is triggered.

Also, some smart key systems can disengage the immobilizer in a vehicle and trigger the ignition without putting a key into the ignition. This happens as long as the driver has the key inside the car. Most cars have a starter button to enable this system to work, while some have a twist on the ignition switch.

A smart key is a key built for electronically accessing a corresponding vehicle. Some vehicles come standard with a smart key, while other automobiles provide a smart key as an upgrade. Smart keys are becoming more stellar with newer models.

Even though smart keys are very to use, you don’t want them to be unsafe. If a vehicle picks up on the low-frequency transmissions of a smart key when a driver is too far from their car, another person can get into the car and even start and drive it. This can occur at the fueling stations, for instance. To avoid theft of vehicles, many carmakers have set the maximum frequency field for various of their smart key systems at 10 cm.
