Step-by-Step Guide to Replacing Your 2005 Cadillac STS Key Fob Battery
Replacing the battery in your 2005 Cadillac STS key fob is a simple DIY task. Here’s a step-by-step guide:
-
Gather Your Tools: You’ll need a small flathead screwdriver or a similar thin tool to gently pry open the key fob casing. You’ll also need your new CR2032 battery.
-
Locate the Notch: Examine your 2005 Cadillac STS key fob. You should find a small notch or slot, usually on the side or bottom of the fob. This is where you’ll insert your flathead screwdriver.
-
Pry Open the Casing: Carefully insert the tip of your flathead screwdriver into the notch. Gently twist or pry to separate the two halves of the key fob casing. Be patient and avoid using excessive force to prevent damage to the plastic.
-
Access the Battery: Once the casing is open, you’ll see the circuit board and the battery. The battery is usually held in place by small clips or a retaining bracket.
-
Remove the Old Battery: Note the orientation of the old battery (positive side up or down). Use your fingertip or the tip of the screwdriver to gently nudge the old battery out of its housing.
-
Install the New Battery: Insert the new CR2032 battery into the battery compartment, ensuring it’s in the correct orientation (matching the orientation of the old battery). It should snap into place securely.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure the casing is fully closed and secure.

Test Your Key Fob: Test all the buttons on your key fob to ensure they are working correctly. Unlock and lock your doors, and try the remote start feature if your vehicle is equipped with it.
