PT Cruiser
The PT Cruiser design is currently available as two designs.

The wiper blade replacement version oscillates back and forth when the rear wiper motor is enabled (note: the PT Cruiser rear wiper only runs intermittently, so key motion is also intermittent).

The other design replaces the rear wiper motor inside the rear deck lid. This design allows the key to rotate continuously whenever the rear wiper switch is ON.

Neither design requires drilling any holes.
