Experiencing a finicky key fob with your 2016 Cadillac ATS? Before you jump to conclusions about a faulty system, consider this: it might just be a dead battery. Key fob batteries don’t last forever, and thankfully, replacing them is usually a quick and easy DIY project. This guide will walk you through everything you need to know about changing the battery in your 2016 Cadillac ATS key fob.
How to Identify a Dying Key Fob Battery
Several telltale signs indicate your Cadillac ATS key fob might be running out of juice. Keep an eye out for these symptoms:
- Decreased Range: You find yourself needing to be much closer to your car for the key fob to lock, unlock, or start the engine.
- Intermittent Functioning: The key fob works sometimes but not others, creating a frustrating game of chance every time you approach your car.
- No Response: The key fob simply doesn’t respond at all, leaving you stranded.
- Dashboard Warning: Your ATS might display a “Key Fob Battery Low” warning on the driver information center.
What You’ll Need for the Battery Replacement
Before you begin, gather the following items:
- A new CR2032 battery: This is the standard battery type for most Cadillac key fobs, including the 2016 ATS.
- A small flat-head screwdriver: This will be used to pry open the key fob casing.
- Optional: A plastic prying tool: This can help prevent scratching the key fob during opening.
2016 Cadillac ATS Key Fob Battery Replacement Steps:
- Locate the key release button: On the back of your key fob, find the small button.
- Release the metal key: Press the key release button and gently pull out the metal key.
- Identify the seam: With the metal key removed, you’ll notice a seam running around the edge of the key fob.
- Gently pry open the fob: Carefully insert the flat-head screwdriver (or plastic prying tool) into the seam. Gently twist the screwdriver to separate the two halves of the fob. Be cautious not to use excessive force, as this could damage the casing.
- Remove the old battery: Once the fob is open, you’ll see the CR2032 battery. Carefully remove it, noting the orientation (positive (+) side facing up).
- Insert the new battery: Place the new CR2032 battery into the fob, ensuring it sits in the same orientation as the old battery.
- Reassemble the key fob: Align the two halves of the fob and press them firmly together until you hear a click, indicating the casing is securely closed.
- Test the key fob: Try locking and unlocking your car, and starting the engine to confirm the new battery works correctly.
Troubleshooting Tips:
- If the key fob still doesn’t work after replacing the battery, double-check that the new battery is properly installed and that the positive (+) side is facing up.
- If the issue persists, try cleaning the battery contacts inside the key fob with a cotton swab and rubbing alcohol.
- In some cases, the key fob itself may need to be reprogrammed. Consult your Cadillac owner’s manual or contact a certified Cadillac dealership for assistance.
Keeping Your Key Fob Happy
Here are a few additional tips to help extend the life of your Cadillac ATS key fob battery:
- Avoid extreme temperatures: Exposing your key fob to extremely hot or cold temperatures can shorten battery life.
- Store it properly: When not in use, store your key fob in a cool, dry place away from direct sunlight and moisture.
- Don’t panic about accidental button presses: Contrary to popular belief, a few accidental button presses won’t significantly drain your battery.
