how long do you have batteries last?
Every time that a driver wants to use their key fob, the battery will have to produce the electricity that is needed to power it. A key fob battery will usually last around three to four years before it will need to be replaced. Not having a fully functional key fob can lead to a lot of frustration and stress. In some cases, it will be impossible for a person to get into their car without a working key fob.
