How to Disable a Taurus Factory Anti-Theft Systemby David Clair
The Ford Taurus is equipped with an anti-theft system that immobilizes the engine to prevent it from being started. Using the wrong type of key or attempting to start the engine without a properly coded key activates the system. The system is designed to discourage unauthorized attempts to start the Taurus by preventing the engine from turning over. Once the anti-theft system has been activated, it must be disabled before the Taurus will operate. This procedure applies to the 2011 model year Ford Taurus.
Press the "unlock" button on the remote entry transmitter.
Insert the coded key into the ignition.
Turn the ignition on. The anti-theft light will turn off after approximately three seconds, indicating the system is disabled. Repeat the steps if the light flashes rapidly or stays on for more than a few seconds.
