Modern cars often include a feature that permits you to start your car remotely. This is especially helpful when you're bringing groceries in or transporting passengers and equipment.
This technology is designed to prevent vehicle theft. Instead of transmitting a single frequency signal as a standard key fob, a smart key sends out various encrypted signals to the car's antennas that are embedded when you are near it. This stops other vehicles from receiving and responding to the same signal, explains How Stuff Works Electronics.
Additionally, some companies incorporate a computer chip into the vehicle to identify the unique fingerprint of each key, which ensures that only authorized drivers are using it. This is particularly useful when you lend your car to family and friends.
Some smart keys can also save user settings, meaning that seat, steering wheel mirror, seat and stereo presets can be automatically set when the key is within the range of the car.

This is a great method to ensure the safety of new drivers and also recommended to have children in the back.
Security
Traditionally keys for cars have been cut from metal and used to unlock the ignition. With smart key technology, this is no longer necessary.

Furthermore, if the smart key battery gets 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 a certain area in the cockpit which transfers energy to an electric motor. Some manufacturers also have an emergency mechanical key blade hidden in the key which can be used to open the trunk and begin the car if required.
Battery Life
The majority of modern cars have keyless entry and push-button start systems that are controlled by a smart key fob, which uses proximity technology to communicate with the car. These systems are powered by a small transmitter that is powered by a lithium coin-sized battery. As with all batteries that eventually requires replacement, this one too will need replacement.
The majority of smart batteries for key fobs last for a while however, this doesn't mean that they won't fail to power up and stop functioning suddenly. If the fob is dead, you are unable to unlock or start your car even if you put it near the front door and the key fob light is flashing.

The fob can also drain the battery if located near other devices which emit electromagnetic fields, such as computers and phones. These gadgets emit magnetic fields of their own, which can interfere and slow down the fob's transmitter. RepairPal states that the fob might not function if it's placed too close to the gadgets.
Maintenance
Smart keys are different from traditional metal keys in that they use technology to control the security of your vehicle in addition to performing other functions.

The most obvious functions are locking and unlocking your car, remote starting and chirping noises to help you locate your vehicle in a parking spot. Certain fobs let you store different settings for various drivers, and remotely open windows and the sunroof.
