What is a Smart Key Car Key?

Sometimes referred to as keys for proximity, key fobs or remote keys, smart keys can be used to unlock doors and start engines without the driver needing to insert the physical key. They communicate via radiofrequency signals.

Many modern vehicles also offer the option to start your engine remotely. This is particularly helpful when you're bringing groceries in or transferring equipment and passengers.

This technology is intended to protect against theft of vehicles. Instead of transmitting one frequency signal similar to a normal key fob it sends out a series of encrypted signals to the car's antennas embedded in it when you are near it. This blocks other cars from receiving and responding to the same signal. explains How Stuff Works Electronics.

Additionally, some manufacturers incorporate a computer chip into the vehicle to identify the unique fingerprint of each key, which ensures that only authorized drivers use it. This is helpful if you lend your car to family and friends.

Some manufacturers also have an emergency mechanical key blade in the key that can be used to open the trunk and start the car should it be needed.

Battery Life

The majority of modern cars have keyless entry systems and push-button starters. These are controlled by a smart key fob that communicates with the car using proximity technology. These systems are powered by a tiny transmitter which is powered by a lithium coin-sized battery. It will eventually need to be replaced, just like any other battery.

The fob can also drain the battery if placed in proximity to other devices that emit electromagnetic field such as phones and computers. These gadgets produce their own magnetic fields, which can affect the fob's transmitter, causing it to function slower. In certain cases, the fob may even cease to function entirely when the fob is placed too close to these devices, according to RepairPal.

Maintenance

In contrast to the traditional car key, a smart one uses technology to control the locks on your vehicle and perform other functions. It operates by transmitting a signal to antennas situated inside and outside of your vehicle. These antennas are able to detect the fob's signal and connect with the car's computer.
