I have an 05 Freestar Limited (mentioned before) I was going to text my alarm. I did that by leaving a window down and locking the doors and waiting a few minutes, and then reaching in and opening the door and unlocking with the button on the door panel, however my alarm doesn't go off. Now I figure I have an alarm system because I have the red blinking light on the dash, along with the key fob, and the door keypad. Anyone know whats goin on?

 

 

I really appreciate your help however if I'm being honest I don't understand wiring diagrams 😕

 

The functionality of your vehicle's security system is contained within the PCM.

You have at least 2 choices and that is either a "certified locksmith with security clearance to access manufacturer info" or a dealership.

Even if you could follow the diagram, you need special info and tools to go further.
