What is a Smart Key Car Key?
Also known as keys for proximity as well as key fobs, remote keys, smart keys can be used to unlock doors and start engines without having to insert the physical key. They communicate with one another by using radiofrequency signals.

Security
Traditionally keys for cars were made of metal and used to unlock the ignition. Smart key technology eliminates this need. Smart keys are equipped with an electronic chip that transmits a signal to your car's antenna. The vehicle recognizes this signal when the driver presses the button on the trunk release or door handle. This means it's impossible to lock your keys in your car.
The signal that the smart key transmits to your car is encrypted, meaning that only the owner is able to use it.

There are many systems that also have backup systems for opening and starting the car in case the battery of the smart keys cars key runs out while riding. The backup system typically consists of putting the key in the slot or placing it near a specific area of the cockpit, which transfers energy to an electric motor. Certain manufacturers have a mechanical key blade that can be used in an emergency situation to open the trunk or to start the car.
Battery Life
Most newer cars have keyless entry and push-button starting systems, controlled by a smart key fob that uses proximity technology to communicate with the car. These systems rely on a small transmitter, powered by a coin-sized lithium battery. It will eventually need to be replaced as with any other battery.
Even though smart key fobs are designed to last for years however, they can suddenly lose power. A dead fob means you can't unlock or start your car, even when you hold it close to the door to the front and the key fob's light blinks.
It's not uncommon for the transmitter of a smart key to drain the battery. It sends a signal to your car each time you press the button, but most times the smart key does nothing. A single lock/unlock signal takes just a tiny portion of the battery power in the fob, so there is easily several years ' worth of signals' worth of battery life in the average smart key battery.
The fob will also drain the battery if you keep it close to other devices emitting electromagnetic fields, for example phones and computers. These devices emit magnetic fields of their own which can cause interference and slow down the fob's transmitter. In some cases, the fob may even stop working altogether when the fob is placed too close to these devices, as per RepairPal.
Maintenance
Unlike the traditional metal car key, a smart key uses technology to manage the locks on your vehicle and perform other functions. It operates by sending a signal to antennas situated inside and outside of your vehicle. They detect the fob's signal and connect with the car's computer. The car is then able to interpret the signal and allows the user to open or start it without having to use the physical key.
New cars are loaded with the latest electronic technology, and the fob has become the hub for many of these functions. The most obvious features include locking and unlocking your car, remote starting and chirping noises to assist you in finding your car in a parking area. Some fobs allow you to save specific settings for different drivers and open windows remotely and sunroofs.
The fob itself is a sophisticated device that has an integrated circuit board, and it is susceptible to damage through repeated use or exposure to cold or heat. The transmitter could be damaged if it is hit or dropped and the contacts on the battery can become bent.
