Why Replace Your Key Fob Battery?

A dying key fob battery can lead to several frustrating situations. You might find yourself standing next to your CT6, pressing the unlock button repeatedly with no response. Or, you might have to resort to using the physical key to unlock your car, which can be inconvenient and even damage the key slot over time. Replacing the battery proactively prevents these hassles and ensures your key fob functions flawlessly.

Identifying a Low Key Fob Battery

Several signs indicate a low key fob battery in your 2016 Cadillac CT6. Reduced operating range is a common symptom. You might notice that you need to be much closer to your car for the key fob to work. Another sign is a weak or intermittent signal. The car might not respond to every button press, or the response might be delayed. Dimming or flickering key fob lights also indicate a dying battery.

Tools You’ll Need for 2016 Cadillac CT6 Key Fob Battery Replacement

The good news is you don’t need specialized tools for this task. A small flathead screwdriver or a similar tool to pry open the key fob is usually sufficient.

Step-by-Step Guide to 2016 Cadillac CT6 Key Fob Battery Replacement

Locate the release button: On your Cadillac CT6 key fob, there’s a small release button. It’s often located on the side or back.
Release the key: Press the release button and gently slide the physical key out of the fob.
Separate the fob halves: Use the flathead screwdriver (or similar tool) to carefully pry open the key fob along the seam. Be gentle to avoid damaging the plastic.
Identify the battery: Inside the key fob, you’ll see the battery. It’s usually a small, round CR2032 battery.
Remove the old battery: Carefully pry out the old battery using your flathead screwdriver.
Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side faces up, just like the old battery.
Reassemble the fob: Snap the two halves of the key fob back together. You should hear a click when they’re securely closed.
Reinsert the key: Slide the physical key back into its slot on the key fob.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Troubleshooting Common Issues

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

Check the battery orientation: Ensure the new battery is installed with the positive (+) side facing up.
Clean the battery contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob. Corrosion can interfere with the connection.
Try reprogramming the key fob: In rare cases, you might need to reprogram the key fob to your car. Consult your owner’s manual for instructions on how to do this.
Check for other issues: If the key fob still doesn’t work, there might be a problem with the key fob itself or the car’s receiver. In this case, it’s best to consult a qualified automotive locksmith or your Cadillac dealer.

How Often Should You Replace Your Key Fob Battery?

Key fob batteries typically last between 3 and 5 years. However, it’s a good idea to replace the battery preemptively when you notice signs of weakening signal or reduced range.

Tips for Extending Key Fob Battery Life

Avoid keeping your key fob near metal objects, as this can drain the battery faster. Also, avoid excessively pressing the buttons when the car is out of range.
