The slot in your device is shallower than a standard coin cell. You need the thinner profile of a CR2016, not a CR2032 that won't seat properly. This Jaycar CR2016 is that 3V lithium button battery – non-rechargeable, single use, sized for the tighter compartments in key fobs, remotes, and small electronics. You match the number on the label, you get the right cell, and it stays put
