What Does the Anti-Theft System Do?
The system warns you of any unwanted access to your truck. You can even get alerts on your phone if you set up the FordPass app.

Check the Key Fob & Cylinder

You should also check your truck’s door lock cylinder for any signs of theft. If there was an attempt of illegal entry into your Ford, inserting the correct key will also activate the anti-theft system.
Use Key in the Door
Insert your key into the door of your F150 on the driver’s side. Then, while the key is in the door hole, try to turn it and leave it in the turned position for 30 seconds.
This will help alert the alarm system that the authorized user is the one trying to open the door of the truck. This could deactivate the anti-theft system.
