Buick Envision key fob battery by model year
Buick fob batteries vary by model year and remote. Buick’s parts catalog lists a CR2032 for Envision models from 2016 through 2020, while the 2025 Envision owner’s manual specifies a CR2450. Those examples do not establish fitment for every Envision or Buick; check the manual for your exact vehicle and the code on the removed cell.
For the 2025 Envision, the manual says to remove the mechanical key, use its blade at the bottom-center seam (not the key slot) to separate the case, and install a CR2450 with the positive side up. Avoid a metal tool, and make sure the silicone mat lies flat before closing the case. Follow the manual for your exact fob design.
