The covered models use a coded fob instead of a traditional metal key. Inserting the fob into the switch allows the use of the engine start/stop switch, which actually starts the engine. Carefully pry off the switch trim, remove the mounting bolts and pull the switch from the instrument panel. Disconnect the electrical connector as the switch is withdrawn. Installation is the reverse of removal. For E-series chassis models, using a blunt, fiat-bladed tool, carefully pry the decorative trim strip/air vents from the instrument panel. Disconnect any electrical connectors as the trim is removed. Squeeze together the clips and push the engine start/stop switch from the trim. Installation is the reverse of removal. For F-series chassis models, using a trim tool, pry out the switch from the instrument panel, then disconnect the electrical connector. Installation is the reverse of removal.
