This is a great method to ensure that new smart car key drivers are safe and also beneficial for families with children in the back of the vehicle.

Security

Traditionally, keys were cut from metal to unlock the ignition. Smart key technology eliminates this requirement. Smart keys have an electronic chip that transmits the signal to the car's antenna.

Some manufacturers have a mechanical key blade that can be used in an emergency to open the trunk or to start the car.

Battery Life

The majority of modern cars have keyless entry and push button starting systems operated by a smart key fob that utilizes proximity technology to communicate with the car. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. As with all batteries that eventually requires replacement, this one too will need replacement.
