Solution

1. Preparation

Tools Required: Small flathead screwdriver, non-marring prying tool (optional)
Ensure you have the correct replacement battery type (CR2032 for GMC Sierra T1XX key fob).

2. Open the Key Fob

Locate the seam on the side of the key fob where the two halves meet.
Use a small flathead screwdriver or a non-marring prying tool to gently pry apart the two halves.
Work slowly to avoid damaging the plastic casing.

3. Remove the Old Battery

Once the key fob is open, identify the battery compartment.
Note the orientation of the battery (which side is positive and negative).
Carefully remove the old battery by pushing it out from the side or using the screwdriver to lift it out gently.

4. Install the New Battery

Place the new CR2032 battery in the same orientation as the old one, ensuring the positive (+) side is facing the correct direction.
Press down gently until the battery is seated securely in the compartment.

5. Reassemble the Key Fob

Align the two halves of the key fob.
Press them together firmly until you hear a click, confirming the fob is securely closed.
