Let's see how to change the battery on a Ford Fiesta key if it is flat. Take your remote key and, using a screwdriver, open the plastic covers: pry with a screwdriver between the two parts of the plastic key cover.

Remove the worn battery, take a new one of the same size and voltage. Reassemble the plastic covers of your remote by pressing on the key cover until you hear it click into place.

Check the proper functioning of the remote key. Always replace the flat battery with one of the same size and never with a different one.
