Before you swap it
- A CR2032 is 3.2 mm thick. CR2016 and CR2025 look the same from the front, but they aren't the same cell, and a thinner one can rattle or lose contact.
- Car still ignoring the fob after a new cell? Check it went in the right way up. The + side usually faces the marking inside the case.
