2 Answers
To replace the battery in a Cadillac remote key, follow these steps: 1. Use a screwdriver to remove the screws on the back cover of the key, then open the cover to access the battery compartment; 2. Remove the old battery and install the new one; 3. Reattach the back cover and secure it with the screws. Taking the 2021 Cadillac XT4 as an example, it is a compact SUV with the following dimensions: length 4600mm, width 1881mm, height 1627mm, and a wheelbase of 2779mm. The 2021 Cadillac XT4 features a MacPherson strut front suspension and a five-link independent rear suspension. It is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 237PS, a maximum power of 174kW, and a maximum torque of 350Nm, paired with a 9-speed automatic transmission.
I've been driving a Cadillac for many years, and changing the remote key battery is a common task—it's quite easy to do. First, place the key on a clean table, locate the small gap along the edge of the cover, and gently pry it open using a thin plastic card or your fingernail. Be careful not to use excessive force to avoid damaging the clips. Once opened, you'll see a coin cell battery secured inside. Use a small tool or your fingernail to remove the old battery, and remember to note the positive side orientation—usually the flat side faces down or has a plus (+) sign. Most Cadillac keys use a CR2032 battery, which you can easily find at any supermarket. When inserting the new battery, ensure it's aligned the same way as the old one, then gently press the cover back into place until you hear a click, indicating it's locked. After replacing, test the key to see if it unlocks the car—if it works, you're done. It's advisable to check periodically; if the remote range shortens or the indicator light dims, replace the battery proactively. Battery life typically lasts about two years, so don't wait until it's completely dead. Also, exposure to water or drops can cause issues, so keep the key dry to prevent damage.
