How to Change Battery on Cadillac Key Fob

A dead key fob battery can turn your sleek Cadillac into a frustrating puzzle. Don’t worry, we’ve got you covered. This guide will walk you through the simple steps of replacing your Cadillac key fob battery, getting you back on the road in no time.

Why is My Cadillac Key Fob Not Working?

Before we jump into the battery replacement process, it’s helpful to understand why your key fob might be acting up. While a dead battery is a common culprit, other issues could be at play:

• Weak Battery: Your key fob battery might have some juice left, but not enough to transmit a strong signal to your car. This can result in intermittent functionality or reduced range.
• Distance: Standing too far from your vehicle can prevent the key fob signal from reaching its intended destination.
• Interference: Other electronic devices or signals in your vicinity could interfere with your key fob’s frequency, disrupting its performance.
• Programming Issues: In some cases, a key fob might lose its programming, requiring reprogramming by a qualified technician.

If you suspect your key fob issues stem from something other than a dead battery, it’s always best to consult your owner’s manual or reach out to a certified Cadillac dealership for assistance.

What Kind of Battery Does a Cadillac Key Fob Take?

Most Cadillac key fobs use a small, flat, round battery known as a CR2032. You can easily find these batteries at most drugstores, supermarkets, and online retailers.

Pro Tip: Consider purchasing a multi-pack of CR2032 batteries. This way, you’ll have spares on hand for future replacements, saving you time and potential headaches down the road.

How to Open a Cadillac Key Fob to Change the Battery

Now, let’s get to the heart of the matter: replacing that drained battery. Follow these easy steps to open your Cadillac key fob and access the battery compartment:

1. Locate the Release Button or Slot: Examine your Cadillac key fob carefully. Look for a small release button or slot, usually located on the back or side of the fob.

2. Release the Key Blade (If Applicable): Some Cadillac key fobs feature a physical key blade that you can use to unlock your car manually. If your key fob has this feature, gently press the release button and slide the key blade out of the fob.

3. Separate the Fob Halves: Once you’ve found the release button or slot, use your fingernail or a small flat-head screwdriver to gently press or pry open the fob casing. The key fob should separate into two halves, revealing the battery inside.

Caution: Avoid using excessive force when opening the fob, as this could damage the casing or internal components.

How to Replace the Battery in a Cadillac Key Fob

With the key fob open, you’re ready to replace the battery. Here’s how:

1. Identify the Battery Orientation: Take note of how the CR2032 battery is positioned inside the fob. The positive (+) side of the battery is typically facing up.

2. Remove the Old Battery: Carefully remove the old battery from its compartment. You can use your fingernail, a small flat-head screwdriver, or a plastic pry tool to gently lift the battery out.

3. Insert the New Battery: Align the positive (+) side of the new CR2032 battery with the positive (+) marking inside the battery compartment. Gently press the battery down until it securely clicks into place.

4. Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating the fob is securely closed.

5. Test the Key Fob: Try locking and unlocking your Cadillac using the key fob buttons to ensure the new battery is working correctly.

Cadillac Key Fob Battery Replacement Cost

Replacing the battery in your Cadillac key fob is a relatively inexpensive DIY task. You can typically find CR2032 batteries for a few dollars at most retailers.
