2 Answers
To replace the battery in a Cadillac XTS key, follow these steps: 1. First, remove the mechanical key. Hold your car key upright, press the metal switch, and pull out the mechanical key. 2. After removing the mechanical key, use a flat-head screwdriver to pry open the key by inserting it into the gap. 3. Once opened, the battery will be clearly visible. However, pay attention to the clips near the battery. Replace it with a new one and reassemble the key. The remote key functions include: 1. Vehicle locator. There is a button on the remote with a horn symbol. Pressing it will make the car alarm sound, effective within a range of over 40 meters. However, use caution in residential areas or during late-night hours. 2. One-touch window closing. Press and hold the lock button on the remote to automatically close all windows.
Last time I helped a friend replace the key battery for a Cadillac XTS, here's a quick guide. The key is a keyless entry fob with a smooth plastic section on the back. Near the top, you'll find a small indentation. Gently push inward with a fingernail or coin to slide open the cover. Remove the old battery—it's a CR2032 coin cell, which you can buy new for just a few bucks at supermarkets or online. When reinstalling, remember the positive side faces up (usually the marked side outward), align it with the battery compartment slot, and avoid reversing it to prevent short circuits. Press the cover back gently to ensure a snug fit without looseness. The whole battery replacement takes about 3-5 minutes, and the battery typically lasts around two years—replace it periodically to avoid sudden failure. After completion, test the unlock button to ensure stable signal transmission and prevent mishaps. It’s cost-effective and simple—skip the dealership markup and enjoy the satisfaction of DIY!
