No key necessary
This person worked at a prison and was in close quarters with a guy who was in for 20-plus years. The guy seemed to be doing fine in jail and was eventually trusted to work in a garage. The warden had just purchased a brand-new Dodge Charger and tasked the inmate with parking it in the garage.
After 30 minutes, the inmate returned without the car. He couldn’t figure out how to turn the car on. So, this guy showed him the keyless ignition system. A simple push of a button was all it took to start that baby right up. Needless to say, the convict/mechanic who probably hadn’t seen a see fob was taken aback by how futuristic cars had become.
