Smart keys are also referred to as proximity keys or key fobs. They function to unlock doors and start engines without a driver having to insert a physical keys. They communicate with each other via radiofrequency signals.

Convenience
Instead of having to insert keys into an ignition slot it is possible to lock and unlock your car by simply pressing the handle of the door or trunk. A lot of modern cars also have a feature that allows you to remotely start your engine. This is particularly useful when you are bringing in groceries, or transporting passengers or equipment.
This technology is designed to help prevent vehicle theft. Instead of transmitting only one frequency signal like a regular key fob does it sends out various encrypted signals to a car's embedded antennas as you come close to it. How Stuff Works Electronics explains that this is a way to prevent other cars from receiving and responding to the same signal.
Certain manufacturers also have a computer-chip in the vehicle which recognizes the unique fingerprint of each key. This helps to ensure that only authorized users use it. This can be beneficial in the event that you lend your car to family and friends.
Some smart keys also store user settings so that mirrors, seat and steering wheel adjustments, as also stereo presets may be automatically set when the key is within reach of the vehicle.

This can help keep inexperienced drivers safe and can be helpful if you have young children in the back.
Security
Traditionally keys were made of metal to open the ignition. Smart key technology eliminates this need. Smart keys have an electronic chip that transmits signals to the car's antenna. This signal is acknowledged by the vehicle when the driver presses a button on the handle on the door or trunk release. It is now impossible to lock your keys into your vehicle.
The signal that the smart key sends to your car is encrypted, meaning that only the owner can use it. A majority of models also shut down the engine if the car hasn't been running for just a few minutes. This feature is particularly useful when you are in a risky location or need to leave your vehicle for any reason.
In addition, if the smart key battery is depleted during a trip, many models have a backup system of opening and starting the vehicle. The backup system involves inserting the key into a slot or holding it close to an area of the cockpit which transfers energy to an electric motor. Certain manufacturers offer a mechanical key blade that can be used in an emergency situation to open the trunk or to start the car.
Battery Life
The majority of newer cars have keyless entry systems as well as push-button starters. They are controlled by a smart device that communicates with the car via proximity technology. These systems rely on a small transmitter, powered by a lithium coin-sized battery. Like all batteries, it eventually needs replacement.
The majority of smart key fob batteries last for several years However, that doesn't mean they'll never go out of power and stop working abruptly. If the fob is dead, it isn't able to unlock or start your car, even if you keep it near the front door and the key fob light flashes.
It's not unusual for the transmitter inside a smart key to drain the battery. It sends a signal to the car every time you push the button, but most times the smart key is not doing anything. A single signal to lock or unlock takes up a miniscule amount of the battery power in the fob and that's many years of signals worth of battery life in the average smart key battery.
The fob is also prone to drain the battery if you place it close to other devices that emit electromagnetic fields, for example phones and computers. These devices emit their own magnetic fields which can cause interference and slow down the fob's transmitter. RepairPal states that the fob can be inoperable if placed too close to the gadgets.
Maintenance
Unlike the traditional metal car key, a smart key utilizes technology to control the locks on your vehicle as well as perform other functions. It operates by transmitting a signal through antennas situated inside and outside of your vehicle. They detect the fob's signal and connect with the car's computer. The car then interprets the signal and allows you to open or start it without having to use the physical key.
New cars are packed with modern electronic features, and the fob has become an instrument for many of these functions. The most obvious ones are locking and unlocking, remote starter, and chirping sounds that help you find your car in a parking space. Some fobs allow you to store specific settings for different drivers and open windows remotely and sunroofs.
The transmitter itself is a sophisticated device that includes an integrated circuit board, and it can be damaged by repeated use or exposure to heat or cold. The transmitter can break when it is damaged by a fall or a bang, and the battery contacts may also be bent.
These problems can be hard to diagnose and fix. You can use your phone to overcome this issue to see if it works. However you should always keep a spare key in your pocket in a case.
