Hey, Had my 93 sc300 auto about a week so far. Today opening my door from the out side my alarm went off. I didnt even kno my car had a alarm and all I have is a key. Then when I tried to start the car it wouldnt turn over but it would turn on. So I happend to finally see a security light on the right sode of the steering wheel. And on the left side under a little bit there is a switch and i flipped it on then off and still couldnt get the car to turn over. So I got out the car and locked it and unlocked it with my key then it decided to turn over. This has happend 2wice 2day. Is there a fix for this or a alarm button for my key chain or something?
