Instead of transmitting a single frequency signal, like a regular key fob smart keys send out an array of encrypted signals to a car's embedded antennas as you are near it. How Stuff Works Electronics explains that it is impossible for other cars to receive and responding the same signal.
Additionally, some manufacturers incorporate a computer chip into the vehicle to recognize the unique fingerprints of each key, which can ensure that only authorized drivers are using it. This is useful in the event that you lend your car to family and friends.

This is a great method to protect new drivers and also beneficial to have children in the back of the vehicle.
Security
Traditionally keys were made of metal to unlock the ignition. With the advent of smart key technology however, this is no longer necessary.

It is now impossible to lock the keys inside your vehicle.
The smart key's signal to your vehicle is encrypted so that only you can access it. A majority of models also shut down the engine if the car hasn't been started in several minutes. This feature is particularly useful when you are in an unsafe location or need to leave your vehicle for any reason.
In addition, if the smart key battery runs out during a journey, many models have a backup system of opening and starting the vehicle. The backup method typically involves putting the key in the slot or putting it near a specific part of the cockpit. This transfers energy to an electric motor. Some manufacturers have a motorized key blade that can be used in an emergency situation to open the trunk or start the car.
Battery Life
Many newer cars have keyless entry and push-button start systems, 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. Like all batteries that eventually requires replacement, this one too will need replacement.

The fob will also drain the battery if you place it close to other devices that emit electromagnetic fields, like phones and computers. These devices emit magnetic fields of their own which can cause interference and slow down the fob's transmitter. In some instances, the fob may even cease to function completely when the fob is placed too close to these devices, according to RepairPal.
Maintenance
In contrast to the traditional car key, a smart one uses technology to manage the locks on your vehicle and perform some other functions. It functions by transmitting a signal from the fob to antennas inside and outside the vehicle. These antennas detect the signal and then communicate with the computer in your car. The car responds to the signal and allows you to open and start it without the physical key.
The fob is now a central point for many electronic features in new vehicles. The most obvious uses include locking and unlocking your vehicle, remote starting and chirping noises to help you locate your vehicle in a parking area. Some fobs even let you store specific settings for various drivers, and also open windows remotely and sunroofs.
The transmitter itself is a specialized device with an integrated circuit board and it is susceptible to damage by hard use or exposure to cold or heat. The transmitter can be damaged if it is damaged by being dropped or smashed. The battery contacts can be bent.
