Many modern vehicles also offer an option that allows you to start your engine from a distance. This is particularly helpful if you are bringing groceries in as well as transporting passengers or equipment.

This technology is designed to help protect against theft of vehicles. Smart keys send out encrypted signals instead of a single frequency, as a regular keyfob does. This prevents other cars from being able to receive and respond to the same signal, which explains how Stuff Works Electronics.

Certain manufacturers also have a computer chip inside the vehicle which recognizes the unique fingerprints of each key. This helps to ensure that only authorized users use it. This is helpful should you lend your vehicle to family and friends.

Furthermore, if the smart key battery runs out during a trip, many systems have a backup method to open and start the vehicle. The backup system typically involves putting the key in the slot or putting it near a specific area of the cockpit, which transfers energy to an electric motor. Certain manufacturers also include an emergency mechanical key blade in the key that can be used to open the trunk and start the car should it be needed.

Battery Life

The majority of newer cars have keyless entry systems and push-button starters. These are controlled by a smart fob which communicates with the car using proximity technology. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. It will eventually need to be replaced as with any other battery.

The majority of smart batteries for key fobs last for a while however this doesn't mean that they won't lose power and stop working at any time. If the fob is dead you won't have the ability to unlock or start your car even holding it near the front door.

The fob will also drain the battery when you keep it close to other devices that emit electromagnetic fields, for example phones and computers. These devices emit their own magnetic fields which can interfere with and slow down the fob's transmitter. In some cases, the fob may even stop working altogether when the fob is placed too close to these devices, according to RepairPal.

Maintenance

Unlike the traditional metal car key, a smart one uses technology to manage the locks on your vehicle as well as perform other functions.

The car interprets the signal which allows you to turn it on or open it without a physical key.
