Step-by-Step 2015 GMC Sierra Key Fob Battery Replacement
Let’s get started with replacing your key fob battery. Follow these easy steps:
Step 1: Open the Key Fob
-
Remove the mechanical key: Locate the small release button or latch on your key fob. Press and hold it while pulling out the mechanical key. Set the key aside.
-
Pry open the back cover: Use a penny or the small flat blade screwdriver to gently pry open the back cover of your key fob. Insert the edge of the penny or screwdriver into the seam of the fob and twist gently. The back cover should pop open.

Step 2: Access the Battery Compartment
-
Locate the small holes: Once the back cover is off, you’ll see the internal housing of the key fob. Look for two small holes on the side of the housing.
-
Separate the housing: Insert the #0 Philips screwdriver (or a similar round object) into one of the holes. Apply firm, gentle pressure straight in, without twisting. This will release a clip. Repeat this process in the other hole.
-
Open the housing: After releasing both clips, you should be able to pull the two halves of the key fob housing apart with your fingers. They should pop right open.

Snap the housing back together: Align the two halves of the key fob housing and press them firmly together until they snap securely shut.
