Recently, automotive manufacturers have been equipping vehicles with a push button start ignition switch that takes the place of a traditional key cylinder. On some vehicles the system is integrated into the entire vehicle entry system and other times not. This feature first appeared in highline vehicles and soon will be “trickling down” to even economy minded vehicles. Whether the vehicle is propelled by internal combustion engine, electricity or hybrid, the days of the keyed lock cylinder appear numbered. This presentation was given in July at NACAT 2009 in North Carolina and explains basic operation on three specific vehicles.
