Problems with push button starting

"A woman in Ontario, Canada, last month hired a rental car, a black Nissan Sentra. Her first stop was a shopping mall. Over the next week or so she drove it almost every day, making a note to herself that when she returned it she’d complain about the car’s messy condition and golf clubs in the boot. Come the day, the rental agency manager was confused. “M’am,” he said, “the car you hired was a Sentra – the car you’ve returned is an Infiniti.” Yep, she’d jumped into the wrong car at the shopping mall. She and the manager found the Sentra parked where she’d left it. The Infiniti’s owner, who had reported it stolen, got his car back, along with a lecture from police about not leaving a keyfob in an unattended vehicle. The woman was reported to be a “wee bit embarrassed.”"

Can't see any problem there both cars started fine 😁

We have two keyfobs each, they stay in hubbies pocket and my bag and are never really removed as they don't need to be.

Brains not quite engaged there I'd have thought, both parties.
