Variously known as keys for proximity Key fobs, proximity keys, or remote keys, smart keys function to unlock doors and start engines without the driver having to insert the key. They communicate with each other by using radiofrequency signals.

A lot of modern cars also have the option to start your engine from a distance. This is particularly useful if you are bringing in groceries or transporting passengers, or equipment.
This technology is designed to prevent vehicle theft.

This stops other vehicles from being able to receive and respond to the same signal, explain how to unlock a smart car without a key Stuff Works Electronics.
Certain manufacturers also have computers in their vehicles which recognizes the unique fingerprint of every key. This helps to ensure that only authorized users use it. This is helpful should you lend your vehicle to friends and family members.

This feature is particularly helpful if you are in a risky location or you need to leave your vehicle for any reason.
Additionally, if a smart key battery runs out during a ride, many systems offer a backup method of opening and starting the vehicle. The backup method is to insert the key in an opening, or keeping it near a particular area of the cockpit which transfers energy to an electric motor. Some manufacturers also have an emergency mechanical key blade in the key which can be used to open the trunk and start the car in case of need.
Battery Life
Most newer cars come with keyless entry systems and push-button starters. These are controlled by a smart fob which communicates with the car through proximity technology. These systems are powered by a tiny transmitter which is powered by a coin-sized lithium battery. It will eventually have to be replaced, just like any other battery.
The majority of smart batteries for key fobs last for a while, but it doesn't mean they won't lose power and stop working suddenly. A dead key fob means that you can't unlock or start your car, even if you keep it close to the door to the front and the key fob's light flashes.

The fob also tends to drain the battery if you place it close to other devices emitting electromagnetic fields, like phones and computers. These devices produce their own magnetic fields, which could interfere with the fob's transmitter, causing it to operate more slowly. In some instances the fob might cease to function entirely if the fob is left too close to these devices, according to RepairPal.
Maintenance
Smart keys differ from traditional metal keys because they use technology to control the security of your vehicle in addition to performing other functions. It works by transmitting an indication from the fob to antennas inside and outside the vehicle. These antennas detect the signal and then communicate with your car's computer. The car interprets the signal, and allows you to begin or open it without a physical key.
New vehicles are loaded with the latest electronic technology, and the fob has become the hub for many of these functions. The most obvious are locking and unlocking, remote start, and chirping sounds that help you find your vehicle in a parking lot. Some fobs even let you store specific settings for different drivers and remotely open windows and sunroofs.
The transmitter itself is a specialized device that has an integrated circuit board, and it is prone to being damaged by hard use or exposure to cold or hot. The transmitter could be damaged when it is dropped or banged or smashed. The contacts on the battery can become bent.
