This is a great method to ensure the safety of new drivers, and it's also recommended if you have children in the back of the vehicle.

Security

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

Battery Life

Most newer cars come with keyless entry systems and push-button starters. These are controlled by a smart key fob that communicates with your car using proximity technology. These systems are powered by a tiny transmitter which is powered by a coin-sized lithium battery. Like all batteries it will eventually need replacement.

Even though smart key fobs are designed to last for a long time but they may suddenly lose power. If the fob is dead, it won't be able unlock or start your car even in the event that you put it close to the front door.

The fob will also drain the battery If you keep it in close proximity to other devices that emit electromagnetic fields, for example phones and computers. These devices emit their own magnetic fields, which can interfere and slow down the fob's transmitter. In some instances the fob could cease to function entirely when it is placed too close to these devices, as per RepairPal.

Maintenance

Smart keys differ from traditional metal keys because they use technology to control the locks of your car as well as perform other functions.
