HOw much would it cost? After I get the car, whats next?
Check to see if your little red light on the drivers door lock button is blinking or red all of the time. If it is I would suggest turning the key in the door twice to the right until the car bleep's, arming the alarm. Then turn the key back to the left twice in two distinct movements. Then try to start. Good luck.
When it goes off, call the cops, they will have him fix it. Do not go near his SUV! Call more then once if you have to. Them after market alarms are junk.. I know someone that got shot, and died over them alarms, Ya call the cops!
