The alarm goes off anytime I open the doors ortrunk I'm trying to figure out how to disconnect the system I have no need for it and it's try annoying. I have a key fob but most of the buttons don't work and i neveruse it anyway. I just want to disconnect the whole anti theft system

Is it under the hood and under the fuse box? Or is it in the trunk?

The car will not start on first crank when lights flash but then it will on second time cranking

It started making a grinding or rubbing sound. Almost like a wheel hub bearing, but I know its not because I took off wheel hub and CV joint and started car and put it in drive up on jack stands. It has to be transmission. It has plenty of fluid, shifts fine. It happens any time I drive.

The rear of my car slides when I turn and feels really loose and my anti-lock brakes ain't working at all either they lock up when I try to stop too fast

when I turn car off it acts like its dying but then wheni turn car back on it starts right up, what could be the problem?

Started misfiring after starting up. Took it is and have spark plugs replaced. Problems still happening whenever fielding the car. Misfiring starts and the check engine light starts blinking.
