No Response: A completely dead key fob will not respond at all.

Replacing the Key Fob Battery: A Step-by-Step Guide

Replacing the key fob battery in a 2003 Honda Accord is a relatively straightforward process. Here’s how:

Gather Your Tools: You’ll need a small flat-head screwdriver and a new CR2032 battery. You can easily find these at most hardware stores, electronics retailers, and even online.
Locate the Key Fob Seam: Look for a small seam or notch on the side of your key fob. This is where you’ll insert the screwdriver.
Open the Key Fob: Gently insert the flat-head screwdriver into the seam and pry the two halves of the key fob apart. Be careful not to damage the plastic.
Remove the Old Battery: Once the key fob is open, you’ll see the old CR2032 battery. Use the screwdriver or your fingernail to carefully remove it.
