To make a long story short, my SC400 didnt come with the remote when I bought it but its not really a big deal to me, I just lock it and unlock it manually. Last night though when I locked it the alarm went off and so I just turned back, unlocked it and locked it. It did it again and again when I went to work, since the only ways are to either leave the car open(which Im not) I have to pop the hood and disconnect the battery. What would cause this all of a sudden? I have a new battery and its really annoying. I got the idea to find the stock alarm cable and disconnect it, anyone know where it is and how looks(color, location) please help me out!!!

 

Did you ever solve this? I have a similar problem, apparently just on one door, but that hasn't been tested extensively.
