Here are the steps to replace the battery in an XTS key: 1. Pull out the metal mechanical key from the XTS key; 2. Use tweezers to press into a groove on the top of the car key until it reaches the bottom, then pry open the battery cover; 3. Replace the battery and reinstall the key cover properly. Additional information: Taking the 2018 Cadillac XTS as an example, it belongs to the mid-to-large-size car category, with body dimensions of length 5103mm, width 1852mm, height 1502mm, a wheelbase of 2837mm, front track of 1580mm, rear track of 1591mm, a fuel tank capacity of 70 liters, and a trunk capacity of 537 liters.
I find replacing the XTS car key battery quite simple, but it requires some care. The key usually has a plastic shell. Find a seam or small hole, and I gently pry it open with a small blade to reveal the coin cell inside. Remember the orientation of the old battery, typically a CR2032 model, which costs just a few bucks at the supermarket. When inserting the new battery, align the positive side correctly to avoid short-circuiting. Finally, press the shell tightly to snap it shut. Test by pressing the key buttons to see if the car lights flash. If the shell is too tight, don’t force it open to avoid breaking—sometimes screws hold it together, requiring a small screwdriver. Weak batteries slow down the car’s response, so I recommend replacing them every two years as a precaution. Doing it yourself saves money and is convenient, but if unsure, follow a tutorial video.
