Question
I am getting a message "car won't start due to security system". I've tried different keys and it still won't start.  I just get the same message.  What could the problem be?

Answer
You will need Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
