How to Open Cadillac Key Fob: Models 2014 and Newer

The new Cadillac key fob was introduced in 2020 with the new CT5, however, it is relatively similar to the models introduced in 2014. The CR2032 battery is a common battery type for many vehicle manufacturers and is required for your Cadillac key fob battery replacement. Learning how to open a Cadillac key fob is easy with these simple steps:

1. On the side of the key fob case, there should be a small release button. Pressing the button to open the case should reveal the metal key inside.

2. Once you remove the key, you’ll see a small opening. Use a flat-head screwdriver to separate the two sides of the case.

3. Inside should be the circuit board on one side and the battery on the other.

4. Pop out the old battery and put the new CR2032 battery in its place. Be sure to have the positive side facing down.

5. Once the battery is in place, simply pop the case back together. Then, test the key fob functions and take advantage of the features of your Cadillac key fob.


The CR2032 is a long-lasting battery commonly found in many car key fobs. Visit our parts center at Val Ward Cadillac to buy your Cadillac key fob battery replacement.
