What is a Smart Key Car Key?

Smart keys are also known as proximity keys or key fobs. They function to unlock doors as well as start engines without having to insert physical key. They communicate with one another using radiofrequency signals.

Instead of transmitting only one frequency signal like a traditional key fob, a smart key sends out a series of encrypted signals to a car's embedded antennas when you come close to it. How Stuff Works Electronics explains that this stops other vehicles from receiving and responding the same signal.

Security

Traditionally keys were made of metal to open the ignition. Smart key technology eliminates this requirement. Smart keys have a special chip that sends signals to your car's antenna.

Some manufacturers also have an key blade that is an emergency mechanical lock in the key that could be used to open the trunk and start the car should it be needed.

Battery Life

The majority of modern cars have keyless entry systems and push-button starters. They are controlled by a smart fob which communicates with your car using proximity technology. These systems use a small transmitter powered by a lithium coin-sized battery. It will eventually have to be replaced just like any other battery.

Although smart key fobs are designed to last for years however, they can suddenly lose power. If the fob is dead, you are unable to unlock or start the car, even when you hold it close to the front door, and the key fob's light blinks.

A single lock/unlock signal takes up a miniscule amount of the fob's battery, so there is easily several years worth of signals worth of battery life left in the average smart key battery.

The fob also drains the battery if it is located near other devices which emit electromagnetic fields like phones and computers. These devices create their own magnetic field, which could interfere with the fob's transmitter, causing it to work slower. In certain cases the fob might cease to function entirely when it is placed too close to these devices, as per RepairPal.
