Replace the key battery of a Ford Focus

Model: Ford Focus MK 3 - Years 2011-2018
Part: Key

Do you want to remove the remote control of the Ford Focus? Remove the covering plastics to access the flat battery located inside the key. Use a screwdriver to pry between the two covers of the key (in the space that joins the two halves). Pry until the plastics separate, then extract the worn battery inside with a small screwdriver. Join the two plastics: press the two halves until you hear the locking click of the two parts. Replace the battery with one of the same size and voltage. Test the operation of the key in all its parts.
