How to Replace the Key Battery in a Ford C-Max?

Model: Ford C Max MK 2 - Years 2010-2019
Part: Key

Replacing the battery in the remote key of the Ford C-Max, if it is flat, is a very simple task as shown in the attached video guide. First, obtain a replacement battery, a CR2032, and a small flat-head screwdriver. Take the remote, insert the screwdriver tip into the small slot located at the bottom, just near the metal ring. Gently lever it until the two halves of the key separate. At this point, remove the flat battery and replace it with the new one, ensuring the correct polarity is observed.
