Mazda2 key fob battery (2015–2019): CR2025

The Mazda2 key fob (2015–2019) takes one CR2025 3V lithium coin cell.

Before you swap it

• CR2016 and CR2032 are the same 20 mm width as a CR2025 but a different thickness, so read the code on the old cell before you order, because a cell that's too thin can lose contact every time the fob gets knocked.
• Note which way up the old cell sits before you take it out. Fitted upside down, the key won't work at all.
