1. Key

A car key or an automobile key is a key used to open and/or start an automobile. Modern key designs are usually symmetrical, and some use grooves on both sides, rather than a cut edge, to actuate the lock. It has multiple uses for the automobile with which it was sold. A car key can open the doors, as well as start the ignition, open the glove compartment and also open the trunk (boot) of the car.

  • Start the engine (by turning the ignition or pressing a start button).
  • Lock/unlock doors.
  • Open the trunk or tailgate.
  • Activate/deactivate the alarm system.
  • Trigger a panic alarm.
  • Control windows or mirrors (in some vehicles).
