The remote key of an EcoSport (across all variants) uses the battery designated as CR2032: C refers to the battery chemistry (lithium type), R refers to the shape (round), 20 and 32 refer to the dimensions (20 mm in diameter, 3.2 mm in thickness).
Battery replacement requires disassembly of the remote key, and was covered in the video (for Trend and Ambiente remotes only) Opening the Boot Door with the Remote.
