What is a Smart Key Car Key?
Differently referred to as proximity keys, key fobs or remote keys, smart keys are used to unlock doors and start engines without the driver having to insert a physical key. They communicate with each other via radiofrequency signals.
This helps to keep vehicles secure by not allowing hotwiring. Smart keys emit unique encrypted signals that keep access to other vehicles.
Convenience
You can lock and unlock your vehicle without needing to insert the key into the ignition slot. Simply press the door handle or trunk. A lot of modern cars also have a feature that allows you to start your engine remotely. This is especially useful if you're bringing groceries into the vehicle, or transporting passengers or equipment.
This technology is designed to help stop theft of vehicles. Instead of transmitting one frequency signal like a traditional key fob smart keys send out a series of encrypted signals to a car's embedded antennas when you approach it. How Stuff Works Electronics explains that this prevents other cars receiving and responding the same signal.
Certain manufacturers also have an electronic chip in the vehicle which recognizes the unique fingerprint of every key. This can help ensure that only authorized users use it. This can be helpful should you lend your vehicle to family members and friends.

Traditionally keys for cars have been made of metal and used to unlock the ignition. With the advancement of smart keys this is no longer a requirement.

In addition, if the smart key battery gets depleted during a ride, a lot of systems come with a backup plan to open and start the vehicle. The backup system involves placing the key in a slot or holding it close to an area in the cockpit where the energy is transferred to an electric motor. Some manufacturers have a mechanical key blade that can be utilized in a situation of emergency to open the trunk or start the vehicle.
Battery Life
Most newer cars come with keyless entry systems as well as push-button starters. They are controlled by a smart device that communicates with the car via proximity technology. These systems use a small transmitter powered by a lithium coin-sized battery. It will eventually need to be replaced, just like any other battery.
Although smart key for smart car fobs are designed to last for years however, they can suddenly lose power. A dead fob means you are unable to unlock or start your car, even if you keep it near the door to the front and the key fob light flashes.

A single lock/unlock signal uses only a fraction of the battery power of the fob, so there is easily several years worth of signals' worth of battery life for the average smart key battery.
The fob may also drain the battery if kept near other devices that emit electromagnetic fields like phones and computers. These devices produce their own magnetic field which could affect the fob's transmitter and cause it to work slower. In some instances, the fob may even be unable to function when it is placed too close to these devices, as per RepairPal.
Maintenance
Contrary to the traditional metal car key, a smart fortwo key programming one uses technology to control the locks on your vehicle as well as perform other functions.
