Ford PATS System Troubleshooting Guide

The Passive Anti-Theft System (PATS) uses a transponder chip in the ignition key to prevent vehicle theft.

When the PATS system is armed, the transponder chip sends a signal to the PCM (Powertrain Control Module). 

The PCM then sends a signal back to the transponder chip. If the signal from the transponder chip is correct, the PCM will allow the engine to start. If the signal is incorrect, the engine will not start.

A few things can cause the PATS system to trigger an error and prevent the engine from starting. 

Faulty transponder chip

A transponder chip is an RFID device that helps identify a vehicle’s owner and allows the engine to start.

The transponder chip is usually placed in the ignition key and sends a signal to the vehicle’s computer, which then verifies that the signal is coming from an authorized key.

The computer will not allow the engine to start if the signal is not coming from an authorized key.

Intrusion between the transponder chip and the PCM

Another possibility is interference between the transponder chip and the PCM.

This interference can be caused by physical objects (such as metal) or electrical pulses (such as those from an electronic garage door opener). 

If you are having trouble with your PATS system, there are a few things you can do to troubleshoot the problem. 

Inspect the battery

Check to make sure that the battery in your key fob is fresh. If it is low, replace it with a new one. 

Hold the key fob

Try holding the key fob close to the steering column when you attempt to start the engine. Sometimes this will help to clear up any interference issues. 

Go to the Ford dealership

If all else fails, you can always take your car to a Ford dealership and have them diagnose and repair any problems with your PATS system.

How To Disable Ford PATS System?

The PATS system is designed to prevent vehicle theft, but it can also be a nuisance if you lose your key or accidentally set off the alarm. If you need to disable Ford PATS system, there are a few things you can try:

Insert the car key into the door

Insert your key into the driver’s side door and turn it to unlock. However, do not remove the key – leave it in for 20-30 seconds so the system can pick up its RF signals.

It will disengage the PATs system! If your keys are not staying put, you can try twitching them to keep them in place.

Once the system has been successfully disengaged, you should be able to start your vehicle as normal. Remember that you will need to repeat this process each time you start your car, so it may be wise to keep an extra key on hand just in case. 

Using an active key fob

The key fob must have a working battery to disable the PATS system. If the battery is dead, the system cannot be disabled. Once a new battery has been installed in the key fob, follow these steps:

  • Enter the car and close all doors.
  • Insert and turn the key to the “On” position.
  • Press and release the panic button on the key fob within five seconds.
  • Turn the key to the “Off” position.
  • The PATS system will now be disabled. 

Put the key in the ignition

Insert the key and leave it in the ignition for 10-15 minutes. It will reset the system and allow you to restart your engine. Once it’s restarted, check to see if the dashboard anti-theft light has gone off.

If it has, then you’re good to go. However, you will have to repeat this method if the light remains on.

Conclusion

Bypassing the Ford PATS system is not difficult, but it requires some specific tools and knowledge. By following the steps outlined in this article, you should be able to bypass the system without any trouble. 

However, it is important to note that this is a temporary measure and that you will need to get a new key made as soon as possible. 

In addition, you should only use this method if you are sure your key is lost or stolen. Otherwise, you could end up damaging your vehicle or causing it to malfunction.
