Replacing the Key/Remote Battery for the Seat Leon

Model: Seat Leon MK 3, 5F - Years 2012-2019
Part: Key

Replacing the key/remote battery for the Seat Leon is a fairly simple operation. The onboard computer indicates when the key/remote battery is low. First, extract the metal key from its slot within the plastic body of the remote by rotating it around its pivot using the small button. Now, using your fingers, pry open the small cover on the plastic body (as seen in the video images), located on the opposite side to the remote buttons, and remove it. At this point, the battery compartment is visible. Use a safety pin to pry out the battery from its slot and replace it with a new one. Refit the cover and you're done!
