I'm having a huge problem! I bought a 2013 Corolla LE last Saturday from a used car dealer. First note: The battery had some corrosion, so I cleaned it. Car ran fine all week. I went to the locksmith today to have the keypad programmed since no functions on it were working. He couldn't get it to work so I puchased a new one which he programmed. I used it twice during the day and all was good. I went to go back out this afternoon and I have absolutely no power in the car. Even the power switches for the door locks don't work. Is this because the engine immobilizer system kicked in? If so how do I reset it? I have no other vehicle to use.
