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

Battery Life

Most newer cars have keyless entry and push-button start systems that are controlled by a smart key for car key fob that utilizes proximity technology to communicate with the car. These systems use a small transmitter, powered by a coin-sized lithium battery. As with all batteries that eventually requires replacement, this one too will need replacement.

Even though smart key fobs are designed to last for a long time They can be suddenly lost power. A dead key fob means that you are unable to unlock or start the car even if you place it close to the front door, and the key fob light flashes.

These devices produce their own magnetic field which can interfere with the fob's own transmitter and cause it to function slower.
