Locate the release slot: On the side of your key fob, you should see a small slot or indentation. This is the release slot for the key.
Release the key: Insert the flathead screwdriver into the release slot and gently pry. The key should pop out.
Separate the fob halves: With the key removed, you should now be able to separate the two halves of the key fob. Use the flathead screwdriver to gently pry open the fob along the seam where the two halves meet. Be careful not to damage the plastic.
Remove the old battery: Inside the key fob, you will see the CR2032 battery. Gently pry the old battery out of its housing, being mindful of the battery’s polarity.
Install the new battery: Insert the new CR2032 battery into the housing, making sure the positive (+) side is facing upwards, the same way the old battery was positioned.
Reassemble the fob: Align the two halves of the key fob and press them together until they snap securely back into place.
Reinsert the key: Slide the key back into its slot on the fob.
Test the fob: Try locking and unlocking your Tahoe to ensure the new battery is working correctly.

Common Issues and Troubleshooting

Sometimes, even after replacing the battery, your key fob might not work. Here are a few troubleshooting tips:

Check the battery orientation: Make sure the new battery is installed correctly with the positive (+) side facing up.
Try reprogramming the key fob: In rare cases, you might need to reprogram the key fob to your vehicle after changing the battery. Consult your owner’s manual for instructions on how to do this.
Inspect the key fob for damage: If your key fob has been dropped or damaged, it might need to be replaced.
