Smart keys are also known as proximity keys or key fobs. They function to unlock doors and start engines without having to insert a physical keys. They communicate by radiofrequency signals.

Convenience

Instead of inserting keys into the ignition slot, you can lock and unlock your car by merely touching the handle on the door or trunk. Many modern vehicles also offer a feature that allows you to start your engine remotely. This is especially useful when you're bringing groceries in or transporting passengers and equipment.

This technology is intended to protect against theft of vehicles. Instead of transmitting one frequency signal like a regular key fob does, a smart key sends out an array of encrypted signals to a car's embedded antennas when you are near it. What does this mean? Stuff Works Electronics explains that this prevents other cars receiving and responding to the same signal.

In addition, some manufacturers incorporate a computer chip into the vehicle to recognize the unique fingerprint of each key, which ensures that only authorized drivers are using it. This is useful in the event that you lend your vehicle to family members or friends.

Certain smart keys also store user preferences, allowing mirrors, seat and steering wheel adjustments as well as stereo presets can be automatically set when the key is within the range of the vehicle. For added convenience, some smart keys can be configured to stop the vehicle from exceeding a specific speed limit when it is initiated with that specific key. This can help keep unexperienced drivers safe, and is particularly beneficial for families with young children in the back.

Security

Traditionally keys were made of metal to open the ignition. Smart key technology eliminates this requirement. smart keys cars keys have a special chip that sends an antenna signal to your car. The car can detect this signal when the driver presses the button on the trunk release or door handle. It is now impossible to lock your keys into your vehicle.

The signal that the smart key transmits to your car is encrypted, which means only the owner has the right to use it. A majority of models also shut down the engine when the car isn't started for several minutes. This feature is particularly useful when you are in an unsafe location or need to leave your vehicle for any reason.

Many systems also have the option of a backup system to open and starting the car when the battery of the smart key goes out while on a ride. The backup system involves inserting the key in an opening, or keeping it close to an space in the cockpit in which energy is transferred to an electric motor. Some manufacturers have a motorized key blade that can be used in an emergency situation to open the trunk or to start the car.

Battery Life

The majority of newer cars have keyless entry systems as well as push-button starters. These are controlled by a smart fob that communicates with the car through proximity technology. These systems use a small transmitter powered by a coin-sized lithium battery. It will eventually require to be replaced just like any other battery.

Even though smart key fobs are made to last for a long time however, they can suddenly lose power. If the fob battery is dead, you won't have the ability to unlock or start your car when you place it close to the front door.

These gadgets emit magnetic fields of their own that can interfere with and slow down the fob transmitter. In certain cases the fob could cease to function completely if the fob is left too close to these devices, according to RepairPal.

Maintenance

As opposed to the traditional car key, a smart one makes use of technology to control the locks on your vehicle, and also perform other functions. It works by sending a signal from the fob to antennas within and outside the vehicle. The antennas pick up the signal and then communicate with the computer in your car. The car interprets the signal, permitting you to start or open it without a physical key.
