Some manufacturers have a mechanical key blade that can be utilized in a situation of emergency to open the trunk or start the car.
Battery Life
Many newer cars have keyless entry systems as well as push-button starters. These are controlled by a smart fob which communicates with the car via proximity technology. These systems are powered by a small transmitter that is powered by a lithium coin-sized battery. Like car smart key programming near me , it eventually needs replacement.
