2 Answers
Buick Excelle key battery replacement method: Pry open the shell along the gap at the lower part of the key, remove the cover plate to expose the internal battery. Extract the old battery and insert the new one into the designated slot (ensure the positive pole faces upward). Finally, reinstall the rear cover to complete the process. The Buick Excelle is built on GM's global platform, with body dimensions of 4468mm (length) × 1765mm (width) × 1469mm (height). Positioned as an entry-level family car, it features dynamic styling, premium interior, a new powertrain system delivering smooth and fuel-efficient performance. All variants come standard with the 10th-generation OnStar assistant (providing 24/7 connectivity), built-in 4G LTE mobile hotspot, and eConnect intelligent interconnection technology.
Last time I replaced the battery in my Buick Excelle key fob myself, and it was actually quite simple. First, you need to prepare a CR2032 coin cell battery, which is very cheap at the supermarket. Place the key fob with the side facing up, and you'll see a small notch. Use a small screwdriver to gently pry open the casing—be careful not to use too much force, as the clips can break easily. Once opened, you'll see the old battery in its slot. Use a small tool to remove the old battery, paying attention to the battery's orientation (positive and negative sides). When inserting the new battery, make sure the positive side faces up and press it in. When reassembling the casing, align it properly and press gently until you hear a 'click,' indicating it's securely in place. Finally, test the unlock and lock buttons to check if the lights work—that's it! The whole process takes less than five minutes and saves you over 200 yuan compared to going to the dealership. If the key fob has been used for a long time, the metal contacts in the battery slot might loosen, so it's a good idea to clean the contacts while you're at it.
