Security
Traditionally, car keys have been made of metal and used to unlock the ignition. Smart keys eliminate this need. Smart keys have a specific chip that sends signals from the antenna to your car. The car recognizes this signal when the driver presses on the trunk release or door handle. This means it's impossible to lock your keys in your car any longer.
The signal sent by the smart key to your vehicle is encrypted so that only you have access to it. Most models also disable the engine if it isn't started for just a few minutes.

A lot of systems also have an alternative system for opening and re-starting the car if the battery of the smart key is drained out while you are on a ride. The backup method typically involves placing the key into the slot or putting it near a specific part of the cockpit that transfers energy to an electric motor. Some manufacturers also have an emergency mechanical key blade hidden inside the key that can be used to open the trunk and start the car in case of need.
Battery Life
Many newer cars have keyless entry systems as well as push-button starters. They are controlled by a smart fob which communicates with the car using proximity technology. These systems are powered by a tiny transmitter that is powered by a lithium coin-sized battery. Like any other battery, it eventually needs replacement.
Although smart key fobs are made to last for many years, they can suddenly lose power. A dead key fob means you won't be able to lock or start your car, even if you place it near the door to the front and the key fob's light blinks.

A single lock/unlock signal uses just a tiny portion of the battery power of the fob which means that there's several years ' worth of signals worth of battery life for the average smart key battery.
The fob may also drain the battery if it is placed in proximity to other devices that emit electromagnetic field, such as computers and phones. These devices emit magnetic fields of their own that can interfere with and slow down the fob's transmitter. In certain cases, the fob may even stop working altogether when the fob is placed too close to these devices, as per RepairPal.
Maintenance
In contrast to the traditional car key, a smart key uses technology to control the locks on your vehicle, and also perform other functions.

The car interprets the signal, allowing you to start or open the door without a physical key.
