How do i program my new ford 2001 windstar pats key?

To program a new PATS key for your 2001 Ford Windstar, you will need two working keys. Insert the first key into the ignition and turn it to the "On" position for about 3 seconds, then turn it back off and remove it. Repeat this process with the second key, then insert the new key and turn it to the "On" position for 3 seconds. If successful, the new key will be programmed, and the security light will turn off.
