Final answer:
Using a stolen key to operate the ignition of a vehicle without the owner's consent is indeed an act of attempted theft, as it shows intent and action towards committing the crime.
Step-by-step explanation:
True or False: Entering a car without the owner's consent and operating the starter with a stolen key constitutes an attempted theft is True. When someone enters a vehicle without the permission of the owner and uses a stolen key to operate the ignition, it's an attempt to take control of the vehicle unlawfully. In law, an attempt to commit a crime involves taking direct action towards its commission, although the action may not result in the completion of the crime. Operating the car's starter with a stolen key demonstrates clear intent and an act in furtherance of the theft, thus constituting attempted theft.
