The method to replace the battery in a Cadillac XTS car key is as follows: First, remove the mechanical key, stand the key upright, press the metal switch, and then pull out the mechanical car key. After removing the mechanical key, use a flat-head screwdriver to pry open the key by inserting it into the gap. Once opened, you will see the battery. Replace it with a new one and reassemble the key. The Cadillac XTS has a body length of 5103mm, width of 1852mm, height of 1502mm, and a wheelbase of 2837mm. Its standard external features include a keyless entry system, automatic xenon headlights, adaptive headlights, and auto-dimming exterior rearview mirrors with folding and memory functions.

I'm quite experienced in replacing the key battery for a Cadillac XTS. First, you'll need to prepare a small flat-head screwdriver or a credit card. Gently pry open the seam of the key fob and slowly work your way around the edges to separate the shell. Remove the old battery inside, which is usually a CR2032 model. Pay attention to the positive and negative markings, and make sure to purchase the same CR2032 model for the replacement, ensuring the positive side faces up when reinstalling. Don't forget to wipe the metal contacts in the battery compartment to keep them clean and dust-free. After installing the new battery, press the cover firmly and test if the remote functions properly. I recommend checking it every one or two years. If the remote control range shortens or the indicator light flashes abnormally, it might be a sign that the battery is running low. Doing it yourself saves time and effort, and a CR2032 can be easily bought at a local supermarket. If you're unsure, it's best to visit a 4S store for assistance.

I've replaced the key battery for my Cadillac XTS several times myself. Locate the small gap in the middle of the key, then carefully pry open the cover using your fingernail or a small knife blade - be gentle to avoid scratches. The old battery is typically a CR2032 coin cell, remember to note the positive terminal position when removing it. Insert the new battery of the same type with the positive side facing up, then firmly press the key components together to ensure proper sealing. Test the remote function immediately after replacement; if it doesn't respond, the battery might be inserted backwards - just recheck. Last time I forgot to clean the contacts which caused temporary malfunction. Pay attention if your car key shows sluggish response, it's better to replace the battery proactively to avoid the embarrassment of being unable to lock your car when going out. Having technicians check it during regular maintenance is also a reliable practice.

I was also a bit nervous when I first started changing the key battery, but it's actually quite simple. Use a thin plastic sheet or a small tool to pry open the edge of the key, then gently lift the cover. Remove the old CR2032 battery inside, and insert the new one with the positive side facing up. Close the cover firmly and test the remote function. Remember to handle it gently and avoid forcing anything to prevent damaging the internal circuits. If the key still doesn't work after replacement, it might be due to improper battery placement or contact issues—in such cases, it's safer to take it directly to a professional repair shop.
