How do I open my Dodge key fob to access the battery?

Opening a Dodge key fob to access the battery is a fairly simple process. Most Dodge key fobs have a small indentation or slot on the side that can be used to pry open the fob. You can use a small flathead screwdriver or a coin to carefully open the key fob without causing damage.

Once you have located the indentation or slot, gently insert the screwdriver or coin and twist to separate the two halves of the key fob.
