Some manufacturers also have an emergency mechanical key blade hidden in the key that could be used to open the trunk and start the car if needed.

Battery Life

The majority of modern cars have keyless entry and push button starting systems that are controlled by a smart key fob that makes use of proximity technology to connect with the car. These systems are powered by a tiny transmitter which is powered by a lithium coin-sized battery. Like any other battery that will eventually require replacement.

Although smart key fobs are made to last for several years however, they can suddenly lose power. If the fob's battery is dead you won't have the ability to unlock or start your car even in the event that you put it close to the front door.

A single signal to lock or unlock takes only a tiny amount of the fob's battery which means that there's several years worth of signals worth of battery life in an average smart key battery.

The fob may also drain the battery when it is located near other devices which emit electromagnetic fields like computers and phones. These gadgets produce their own magnetic field, which could interfere with the fob's own transmitter and cause it to work slower.
