Mother used Wrong key in trying to start car (2012 corolla) and security system locked down car . Now using correct key and car won't start

Asked by Jan 28, 2017 at 02:01 PM about the 2012 Toyota Corolla LE

Question type: Maintenance & Repair

My 86 year old mother tried to start her car with keys from her old toyota carrolla (1998) and it appears the security system has locked the car. After getting her actual keys to the car and trying to start it up it won't start. I don't have a smart key, just a fob key how do I reset the car so that the keys will work?

Usually you wind up at the dealer to have the system reset, but you can try manually lock the doors from the inside but the drivers door, then with key in hand close and the drivers door with the key, watch the dome light until it goes oput then wait at least one minute, then using the key unlock the drivers door and attempt to start the engine, if it works then you just saved yourself a bunch of cash, if it didn't then your stuck with a tow job and the dealers charges.
