Security Warning Light Indicator

I kept getting a security light on my dash board and now the car starts and then stalls. I got some info about the passlock system but I got confused. My question is, can I overide the system? Do I have to take it to the dealer, tow it in my case or are there some other qualified shops somewhere in the Phoenix area that can fix this problem. Please help!!!
