Ok I have run into similar issues except for the alarm sounding. Check all the power and ground cables paying close attention to the one in the transmission tunnel. If you find it loose then remove the center console and you will see the 13mm nut may be loose on the cable on the passenger side. Also check for corrosion in the fuse box connectors.
