What offense is committed when a man steals a car that does not belong to him after grabbing the keys?

The offense committed when a man steals a car that does not belong to him after grabbing the keys is categorized as auto theft. Auto theft specifically refers to the unlawful taking of a vehicle with the intent to permanently deprive the owner of it. In this scenario, the act of seizing the keys indicates a clear intention to take the vehicle — reinforcing the classification as auto theft, since the elements of taking and the vehicle's ownership status are satisfied.

Robbery typically involves taking property from a person through threat or use of force, which does not apply in this case where the act centers purely on the unauthorized taking of a vehicle without direct confrontation. Burglary involves unlawfully entering a structure to commit a crime inside, which is not relevant since the focus here is on the car itself. Grand theft generally refers to the theft of property exceeding a certain value but would still fall under the broader category of auto theft if specifically involving a vehicle. The proper charge in this case focuses on the nature of the offense as it pertains to the unlawful taking of an automobile.
