What is a Smart Key Car Key?
Smart keys are also referred to as proximity keys or key fobs. They can be used to unlock doors as well as start engines without a driver having to insert a physical key. They communicate with one another through radiofrequency signals.

Certain manufacturers also include an key blade that is an emergency mechanical lock in the key that could be used to open the trunk and start the car should it be needed.
Battery Life
Many newer cars have keyless entry systems and push-button starters. They are controlled by a
smart car key fob programming fob which communicates with your car using proximity technology. These systems are powered by a tiny transmitter that is powered by a lithium coin-sized battery. As with all batteries that eventually requires replacement, this one too will need replacement.

The fob can also drain the battery if kept near other devices that emit electromagnetic fields such as computers and phones. These devices generate their own magnetic field, which can interfere with the fob's transmitter, causing it to work slower. In some instances, the fob may even be unable to function when it is placed too close to these devices, as per RepairPal.
