Certain manufacturers also include an emergency mechanical key blade hidden inside the key that can be used to open the trunk and start the car in case of need.

Battery Life

The majority of modern cars have keyless entry and push button starting systems that are controlled by a smart key fob that uses proximity technology to connect with the car. These systems are powered by a small transmitter which is powered by a lithium coin-sized battery. It will eventually need to be replaced just like any other battery.

The fob may also drain the battery if it is placed near other devices that emit electromagnetic field like computers and phones. These devices emit magnetic fields of their own which can cause interference and slow down the fob transmitter. RepairPal reports that the fob could not function if it's placed too close to the gadgets.
