Convenience

You can lock and unlock your vehicle without inserting the key into the ignition slot. Simply touch the door handle or trunk. Many modern vehicles have an option that allows you to start your engine from a distance.

This will help keep new drivers safe and can be beneficial for families with young children in the back of the vehicle.

Security

Traditionally, car keys have been cut from metal and used to unlock the ignition. With smart key technology, it is no longer a requirement. Smart keys have a specific chip that transmits an antenna signal to your car.

A number of systems also include backup systems for opening and starting the car when the battery of the smart key runs out while on a ride. The backup system involves inserting the key in a slot, or holding it close to a specific location in the cockpit, which transfers energy to an electric motor. Certain manufacturers offer a mechanical key blade that can be used in an emergency to open the trunk or to start the car.

Battery Life

Many newer cars have keyless entry systems and push-button starters. These are controlled by a smart device that communicates with your car using proximity technology.
