What Fords have the pats system?

Most Ford cars, trucks and SUVs built in the late 1990s and later include the Passive Anti-Theft System (PATS). In practice, if your Ford requires a coded transponder key with a chip to start, it has PATS. This article outlines which Ford models commonly feature PATS, how to identify it, and what to do if you need a replacement key or diagnosis.


Models commonly equipped with PATS


The following list covers Ford models that have widely been equipped with the Passive Anti-Theft System across most markets. It is not exhaustive; some older or special-issue variants may lack the system or use a different immobilizer configuration.



  • Mustang (modern generations from the 1990s onward)

  • F-Series trucks, including F-150 and heavier-duty variants

  • Explorer (since the late 1990s/early 2000s models)

  • Escape

  • Edge

  • Fusion

  • Taurus

  • Focus

  • Fiesta

  • Bronco (modern 4x4 lineup)

  • Expedition

  • Ranger

  • Transit and Transit Connect (commercial vans)


These examples illustrate the breadth of Ford’s adoption of immobilizer technology across passenger cars, SUVs and light trucks. Markets outside North America may have variations, and certain base-trim or fleet configurations could differ.


How to tell if your Ford has PATS


Use these steps to verify whether your Ford uses the Passive Anti-Theft System. Each step helps you confirm the presence or absence of PATS and related components.



  1. Check the ignition key for a transponder chip. A coded/ transponder key is a strong indicator that PATS is installed.

  2. Look at the dashboard security indicator. A small padlock or key icon may flash or stay lit if the immobilizer is active or if there’s a mismatch with the key.

  3. Consult the owner's manual or service documentation for your Vehicle Identification Number (VIN). The documents often list “immobilizer” or “PATS” as an equipped feature.

  4. Ask a Ford dealer or a qualified automotive locksmith to confirm via VIN or by scanning the vehicle’s modules. They can verify whether a PATS control module is present and active.


Understanding whether PATS is present can save time and expense if you need key replacements or a diagnostic check, especially since some older keys or non-transponder keys may not interact with the system.


Why PATS matters and how it works (overview)


PATS works by recognizing a coded transponder in the key and communicating with the vehicle’s engine control system to permit starting. If the key isn’t recognized, the engine will not start, helping deter theft. While broadly standard in modern Ford models, some legacy or fleet vehicles may use alternative immobilizer setups, and certain markets may have unique implementations.


For most owners, issues with PATS typically involve a worn or damaged transponder key, a faulty ignition cylinder, or a diagnostic mismatch. In such cases, a dealership or licensed locksmith with the proper tools can diagnose and restore service by programming a replacement key or reprogramming the immobilizer if necessary.


Summary


The Passive Anti-Theft System is a standard feature on the majority of contemporary Ford vehicles, spanning popular models across cars, SUVs and trucks. If your Ford uses a transponder-equipped key, it almost certainly includes PATS. Verification can be done through the key type, dashboard indicators, official manuals, or a dealership diagnostic. Always consult a qualified professional if you need key replacements or immobilizer-related service.

How do I tell if my Ford has pats?


How do I know if my Ford is equipped with the Securilock Passive Anti-Theft System (PATS)? Many Ford models come with PATS as a standard or optional feature. You can usually find this feature listed in your vehicle's specifications or by noticing the anti-theft indicator on the dashboard.



What triggers the Ford anti-theft system?
