How do you reset the anti theft on a ford windstar?

There's no single "reset" button for the Ford Windstar's anti-theft system. The system is integrated into the car's computer and usually activates only under specific conditions, like a break-in attempt or a malfunction. Problems with the anti-theft system usually manifest as the car not starting or having intermittent starting issues.

If your Windstar isn't starting and you suspect the anti-theft system:

1. Check your keys: Make sure you're using the correct key, including any transponder chips inside. Try all available keys. A weak battery in your key fob can also sometimes cause starting problems. Replace the battery if necessary.

2. Wait and try again: Sometimes, a temporary glitch in the system can cause a false alarm. Wait a few minutes and try again.

3. PATS (Passive Anti-Theft System) issues: The Ford Windstar uses a Passive Anti-Theft System (PATS). If the system is malfunctioning, you'll need professional help. This could involve:

* Key programming: A dealership or locksmith specializing in Ford vehicles can reprogram your keys or the car's computer to recognize the keys. This is often necessary if you've lost keys, had the car's computer work done, or suspect a PATS malfunction.

* Computer diagnostics: A mechanic can use a scan tool to diagnose any problems with the PATS system or other related modules. This might reveal a faulty sensor or other component that needs replacement.

* Replacing the PATS module: In rare cases, the PATS module itself might need replacement. This is a job best left to a qualified mechanic.

Important Considerations:

* Never attempt to bypass or disable the anti-theft system yourself. This could damage your vehicle's electronics and might void your warranty.

* Avoid using aftermarket key fobs or programming tools. Use only OEM (Original Equipment Manufacturer) parts and procedures to avoid compatibility issues.

In short, there's no simple reset. If you're having anti-theft related starting problems, you'll need professional help to diagnose and fix the issue. A qualified mechanic or Ford dealership is your best bet.
