Changing a dead key fob battery can be a quick and easy process, saving you the hassle and expense of a dealership visit. This guide provides clear instructions on how to change the battery in your Cadillac key fob, covering various models and common questions.
Understanding Your Cadillac Key Fob
Before diving into the battery replacement process, it’s helpful to understand the different types of Cadillac key fobs. Cadillac, like many other luxury car manufacturers, utilizes advanced technology in their key fobs. Recognizing your specific key fob type is crucial for choosing the correct replacement battery. Older models might have a different design and battery type than newer, proximity-based key fobs. Understanding this distinction will ensure a smooth battery replacement process.
Locating the Release Button
Most Cadillac key fobs have a small release button or switch. This button is often located on the side or back of the fob. Pressing this button will allow you to separate the key fob casing and access the battery compartment. Sometimes, the release button can be quite small and inconspicuous. A small flathead screwdriver or a similar tool can be helpful in locating and pressing this button.
Opening the Key Fob
Once you’ve located the release button, carefully press it and separate the two halves of the key fob casing. Some Cadillac key fobs may require a bit of gentle prying to separate the two halves. Be cautious during this step to avoid damaging the key fob casing. If you are struggling to open it, you can check online resources specific to your Cadillac model.

Identifying the Battery Type
Inside the key fob, you’ll find the battery. Take note of the battery type printed on the battery itself. Common Cadillac key fob batteries include CR2032, CR2025, and CR2450. Make sure to purchase the correct battery type for your specific key fob model. Using the wrong battery type can potentially damage the key fob or cause it to malfunction.
Installing the New Battery
Once you have the new battery, carefully insert it into the battery compartment, ensuring the positive (+) and negative (-) sides are oriented correctly. Most key fobs have markings indicating the correct battery orientation. After inserting the battery, close the key fob casing by snapping the two halves back together. Test the key fob to ensure it is functioning properly.
What if My Key Fob Still Doesn’t Work?
If your Cadillac key fob still isn’t working after replacing the battery, there could be other issues at play. It might be a problem with the key fob’s programming. In such cases, you might need to reset the key fob. For more details, check out our guide on can you reset car key fob.
