Funny story, not really, about my better halfs uncle/aunt and their Buick LaCrosse and keyless entry. He's a retired AF bomber pilot. To make a long story short, he didn't have his key fob in his pocket to start his push button car. His wife, sitting next to him, had her fob in her purse in the passenger seat, BUT the car wouldn't turn over cuz it didn't read him as having the key. He had someone try to jump the battery. HUGE mistake. Thank God for his extended warranty. He did over $3k worth of damage to the electrical system by trying to jump start it with that push button auto start. After mine developed a short in my 13 Avalon, I said never again.
