What Is Ford PATS System?
PATS system (Passive Anti-Theft System) is an electronic security system.
It prevents unauthorized people from starting a Ford vehicle. Through a transponder key, the system communicates with the ECU (Engine Control Unit) of the vehicle.
The ECU sends a signal to the transponder chip when anyone inserts the key into the ignition. The engine will start only when the chip responds with the correct code.

How to Disable Ford PATS System [3 Methods to Use]
Method 1: By Using Original Key
To disable the Ford PATS system with the original key, follow these steps:
- Remove the ignition key from the ignition.
- Using a flathead screwdriver, carefully pry open the key fob housing.
- Remove the transponder chip from the key fob housing.
- Insert the transponder chip into the ignition.
- Turn the key “On”.
- The PATS system will now be disabled.
Note: The PATS system will be disabled only when the transponder chip is inserted into the ignition. If the transponder chip is removed, the PATS system will be reactivated.
Method 2: By Bypassing Ford Immobilizer
Here are the steps on how to bypass a Ford immobilizer using a bypass module:
- Purchase a bypass module from a dealer.
- Locate the diagnostic port on your vehicle. Under the steering wheel, you will find the diagnostic port.
- Plug the bypass module into the diagnostic port.
- Turn the ignition “ON”.
- The immobilizer will be disabled.

Method 3: By Using a Transponder or Programmed Key
To disable the Ford PATS system using a transponder or programmed key, you will need the following:
- A transponder or programmed key for your vehicle
- A flathead screwdriver
- A piece of tape
Instructions:
- Locate the transponder or programmed key. This is usually a small, black box with a chip inside.
- Use the flathead screwdriver to open the transponder or programmed key.
- Carefully remove the chip from the transponder or programmed key.
- Place the chip near the ignition lock.
- Insert the transponder or programmed key into the ignition lock.
- Turn the key “On”.
- The engine should start.
- Once the engine starts, you can remove the transponder or programmed key from the ignition lock.
The chip in the transponder or the programmed key will send a signal to the PATS system, which will allow the engine to start. You can now start your vehicle using any copy of the key.

Things to Consider Before Disabling PATS
The Age of Your Car
If your car is relatively new, it may be worth keeping PATS enabled for added security. However, if your car is older, the security benefits of PATS may be outweighed by the inconvenience of having to use a key fob.
Your Driving Habits
If you live in a safe area and don’t drive your car very often, you may not need the added security of PATS. However, if you live in a high-crime area or drive your car for long distances, PATS may be a good way to deter theft.
Your Budget
If you’re on a tight budget, you may want to consider disabling PATS to save money on a new key fob. However, if you can afford it, a new key fob may be worth the added security.
Risks of Disabling Ford’s PATS System without Professional Help
You should not disable your Ford’s PATS System yourself if you are not a qualified mechanic or don’t have the mechanical knowledge.
- If you disable the system yourself, there is a possibility of damaging your vehicle or voiding the warranty.
- It is best to consult with a professional mechanic or a Ford dealership if you are considering disabling the PATS system.
