Anti theft reset button located at in a 1999 ford windstar?

There's no single "anti-theft reset button" in a 1999 Ford Windstar. The anti-theft system, called the PATS (Passive Anti-Theft System), is integrated into the ignition system. If you're having trouble starting the vehicle because of the anti-theft system, the problem is likely one of the following:

* Faulty ignition key: The most common cause. The transponder chip in your key might be malfunctioning or the key itself might be damaged. Try all your keys.

* Low battery: A weak battery can sometimes interfere with the PATS system. Try jump-starting the vehicle.

* Faulty ignition switch: The switch itself could be failing.

* Wiring issues: Problems with the wiring related to the ignition system can also trigger the anti-theft system.

You will NOT find a reset button to bypass the system. Attempting to bypass or disable the PATS system yourself is strongly discouraged. It's complex and could potentially damage your vehicle's electrical system.

If you're locked out of your Windstar due to anti-theft, you should contact a locksmith specializing in automotive security or take your vehicle to a Ford dealership or trusted mechanic. They have the tools and expertise to diagnose and repair the problem.
