What is a Smart Key Car Key?
Also known as proximity keys as well as key fobs, remote keys, smart keys are used to unlock doors and start engines without having to insert the physical key. They communicate by radiofrequency signals.
Among other things, this helps protect vehicles by stopping hotwiring attempts. Smart keys also transmit unique encrypted signals to prevent them from being used by vehicles of other drivers.
Convenience
Instead of inserting keys into the ignition slot it is possible to lock and unlock your car by simply pressing the handle on the door or trunk. Many modern vehicles also offer a feature that allows you to remotely start your engine. 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. Smart keys send out encrypted signals instead of a single frequency like a normal keyfob. This prevents other cars from receiving and responding to the same signal. explain how Stuff Works Electronics.
Certain manufacturers also incorporate a computer chip inside the vehicle that detects the unique fingerprint of each key. This makes sure that only authorized users are using it. This is particularly useful for when you loan your car to family and friends.

Security
Traditionally keys were cut from metal to open the ignition. With the advancement of smart keys however, this is no longer the case. Smart keys have a special chip which sends signals from the antenna to your car. The signal is then recognized by the vehicle when the driver presses on the door handle or trunk release. This means it's not possible to lock your keys in your car.
The smart key's signal to your vehicle is encrypted to ensure that only you can use it. The majority of models also shut off the engine if it hasn't been started in several minutes. This feature is particularly useful when you are in a dangerous area or have to leave your vehicle for any reason.
Furthermore, if the smart key battery is depleted during a ride, a lot of systems have a backup method to open and start the vehicle. The backup system typically involves putting the key in the slot or placing it in a certain area of the cockpit that transfers energy to an electric motor. Certain manufacturers also include an emergency mechanical key blade in the key which can be used to open the trunk and start the car should it be needed.
Battery Life
Most newer cars come with keyless entry systems and push-button starters. These are controlled by a smart fob that communicates with the car through proximity technology. These systems rely on a small transmitter that is powered by a coin-sized lithium battery. It will eventually have to be replaced just like any other battery.
The majority of smart key fob batteries last several years however, this doesn't mean that they won't fail to power up and stop functioning quickly. A dead key fob means that you are unable to unlock or start your car even if you place it near the door to the front and the key fob light flashes.
It's not unusual to find the transmitter in a smart key to drain the battery. The smart key transmits an alert each time you press a button. However, most of the time, it doesn't do anything. A single lock/unlock signal takes up a miniscule amount of the battery power of the fob and, therefore, there'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 keep it close to other devices that emit electromagnetic fields, for example phones and computers. These gadgets emit their own magnetic fields which can cause interference and slow down the fob's transmitter. RepairPal reports that the fob could cease to function if placed too close to the gadgets.
Maintenance
As opposed to the traditional car key, a smart key makes use of technology to control the locks on your vehicle, and also perform other functions. It works by transmitting signals from the fob to antennas located inside and outside the vehicle. These antennas receive the signal and communicate with the computer in your car. The car interprets the signal and allows the user to open or start it without having to use the physical key.
The fob is now a center of numerous electronic features found in modern automobiles. The most obvious are locking and unlocking, remote start, and chirping sound to assist you in finding your vehicle in a parking lot. Some fobs allow you to store various settings for different drivers, and can even remotely open windows as well as the sunroof.
The fob is a complicated device with an integrated circuit board and it can be damaged by hard use or exposure to cold or hot. The transmitter could be damaged if it is damaged by a fall or a bang and the battery contacts can also become bent.
