To change the battery in the smart key for the 2017 Nissan Pathfinder, you will need a CR2032 or a similar 3-volt battery. The process is quick and easy, taking only a minute. Start by extracting the mechanical key from inside the key fob. Next, use a flat head screwdriver or another tool to gently separate the two halves of the fob. This will allow you to reach the old battery, which can be easily swapped out for a new one. After replacing the battery, reassemble the fob by putting the parts back together.
