How to Replace the Key Battery for Cadillac ATS-L
2 Answers
Press the side button near the bottom of the remote key and pull out the key. Insert a flat tool into the center of the remote key's bottom to separate the two halves of the remote key. Do not use metal objects. Insert the new battery into the battery slot, paying attention to the positive and negative poles. Reinstall a CR2032 or equivalent battery.
I recently helped my family replace the battery in their Cadillac ATS-L key fob. The battery model is usually CR2032, and you can buy good brands on Taobao for just a few yuan. When replacing it, first use a fingernail or a small card to pry open the gap on the back of the key fob—be careful not to use too much force to avoid cracking it. After removing the old battery, insert the new one, making sure to align the positive and negative poles correctly. Finally, gently snap the cover back on and test the remote control range. I found this task isn’t difficult, but I recommend doing it under good lighting to prevent small parts from getting lost. The battery typically lasts about two years, and replacing it early when the signal weakens can save hassle on long trips. I keep a spare battery on hand just in case.
