You’ll be happy to hear that this process isn’t as difficult to do as you might think.

How Long Does a Car Key Fob Battery Last?

All car key fobs contain electronic chips that they use as transmitters. When you push one of the buttons on a car key fob, the electronic chip in your fob will send a signal in the direction of your car and let it know that you would like to lock/unlock the doors, sound the panic alarm, remote start your car, etc. But this electronic chip won’t be able to do this without a fully functioning car key fob battery.
So, how long does a car key fob battery last? It’s really going to depend on how often you use it and how close you tend to keep it to your car. But generally speaking, most car key fob batteries will last for three to four years before they’ll need to be replaced. So you shouldn’t have to worry too much about trying to change the battery in a Nissan key fob too often.

- Your car key fob doesn’t seem to be working from the same distances that it used to.
