What is a Smart Key Car Key?
smart car key fob replacement keys are also known as proximity keys or key fobs. They work to unlock doors as well as start engines without needing to insert physical key. They communicate by radiofrequency signals.

Convenience
You can lock and unlock your vehicle without inserting the key into the ignition slot. Simply tap the handle on the trunk or door. Modern cars often come with a feature that allows you to start your car from a distance. This is particularly useful if you are bringing groceries in or transporting passengers, or equipment.
This technology is designed to stop theft of vehicles. Smart keys transmit encrypted signals instead of a single frequency similar to a traditional keyfob. This prevents other cars from being able to receive and respond to the same signal. explaining how Stuff Works Electronics.
Certain manufacturers also have an electronic chip in the vehicle which recognizes the unique fingerprint of every key. This helps to ensure that only authorized users are using it. This is useful if you loan your vehicle to family members or friends.
Certain smart keys can also store user settings, ensuring that seat, steering wheel, mirror, and stereo presets are automatically set when the key is in the range of the vehicle.

This is a great method to keep new drivers safe and it's a good idea for families with children in the back of the vehicle.
Security
Traditionally keys for cars were made of metal and used to unlock the ignition. Smart keys eliminate this need.

Additionally, if the
smart key fob key battery runs out during a ride, many models have a backup system to open and start the vehicle. The backup system usually involves putting the key in a slot or holding it in a particular area of the cockpit, which transfers energy to an electric motor. Certain manufacturers also include an emergency mechanical key blade hidden in the key that 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 as well as 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 powered by a lithium coin-sized battery. It will eventually have to be replaced, just like any other battery.
Even though smart key fobs are made to last for a long time however, they can suddenly lose power. If the fob's battery is dead you won't have the ability to unlock or start your car even holding it close to the front door.
It's not unusual for the transmitter of the smart key to drain the battery. It sends a signal to the car each time you press an option, but the majority times the smart key is not doing anything.

The fob also drains the battery if it is placed near other devices that emit electromagnetic fields such as phones and computers. These devices create their own magnetic field, which can interfere with the fob's own transmitter and cause it to work slower. In some instances the fob might cease to function entirely when the fob is placed too close to these devices, as per RepairPal.
Maintenance
Smart keys are different from traditional keys in that they utilize technology to control the locks on your vehicle and perform other functions. It operates by transmitting a signal to antennas placed inside and outside your vehicle that detect the fob's signal and communicate with the car's computer. The car interprets the signal allowing you to start or open it without the physical key.
New vehicles are loaded with the latest electronic technology and the fob is now an instrument for many of these functions. The most obvious ones are locking and unlocking, remote starting and chirping sounds to aid in finding your vehicle in a parking lot.
