Step-by-Step Instructions

Follow these steps to replace the battery in your Chrysler 300 key fob:

Step 1: Locate the Slot

First, find the small slot on the key fob. This is where you will insert the flathead screwdriver. Hold the key fob firmly to avoid slipping.

Step 2: Insert the Screwdriver

Insert the flathead screwdriver into the slot. Gently twist the screwdriver to create an opening. Continue to work your way around the opening by pushing in and twisting the screwdriver. Be patient and go slowly to avoid damaging the key fob.
