This can help keep novice drivers safe and is useful if you have young children in the back of the vehicle.

Security

Traditionally, car keys have been made of metal and used to unlock the ignition. Smart key technology eliminates this need. Smart keys have a specific 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 for car key transmits to your car is encrypted, meaning that only the owner of the car can use it.

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

Battery Life

Many newer cars have keyless entry and push-button starting systems, controlled by a smart key fob, which uses proximity technology to communicate with the car. These systems are powered by a tiny transmitter that is powered by a coin-sized lithium battery. Like all batteries, it eventually needs replacement.

Even though smart key fobs are made to last for a long time They can be suddenly lost power. A dead fob means you won't be able to lock or start your car, even if you place it near the front door. The key fob's light flashes.

The fob is also prone to drain the battery if you place it close to other devices that emit electromagnetic fields, such as phones and computers. These gadgets produce their own magnetic field, which can affect the fob's transmitter, causing it to work slower. In some cases the fob might be unable to function in the event that the fob is too close to these devices, as per RepairPal.

Maintenance

As opposed to the traditional car key, a smart key utilizes technology to control the locks on your vehicle and perform some other functions.
