Can you imagine not being able to start your car just because you were a little slow?

What if your car’s anti-theft system is fully broken, which is far worse?

You’ve come to the right place if you’re wondering how to reset the anti-theft system in your Ford.

The Ford Anti-Theft System is one of the most notable features of a new Ford vehicle.

Yet anti-theft systems are infamous for their annoying quirks.


How To Reset Anti Theft System Ford


To reset the anti-theft system, your transponder key or key fob must be recognized.

You can achieve this recognition in two ways: by inserting it into the driver’s side door lock or by placing it in the ignition.

If you opt for resetting the anti-theft system via the driver’s side door lock with your Ford transponder key, follow these straightforward steps.

First, insert the key and turn it slightly just enough to engage without unlocking the door.

Then, keep the key in this turned position for 40 to 60 seconds, allowing the anti-theft system to detect the embedded code.

After that, flip the key the other way and hold it there for an additional 40 to 60 seconds.

Finally, remove the key, take your place behind the wheel, and attempt to start the engine.

If the Ford anti-theft system successfully resets, the engine will engage, and you’re ready to roll.

Alternatively, you can use a similar method by inserting the transponder key into the ignition.

Turn the key slightly to activate the electrical system.

You may observe a solid or blinking anti-theft light on the dashboard, though not always.

Regardless, leave the key in this position for approximately two to three minutes.

When your Ford detects the transponder key in the ignition, it should reset the anti-theft system, allowing the engine to start.

Be patient, as it may take a few tries to succeed.

If you’ve attempted this process multiple times without success or lack the transponder key or key fob, it’s advisable to seek assistance from a professional vehicle technician to resolve the issue.


What Is An Anti Theft System In A Car?



Anti-theft devices are designed to prevent vehicle theft.

The anti-theft system is a device installed in your car for this purpose.

It serves as a safeguard against auto theft, protecting your vehicle.

Ford vehicles are equipped with an active anti-theft system known as PATS.

It includes an alert and engine immobilization feature.

When the system detects an attempt to start the vehicle using a false key or an unusual method, it prevents the engine from starting by cutting off the power supply.

Ford is a globally recognized and successful automobile manufacturer known for its technology-packed vehicles designed to simplify the driving experience.

Many Ford vehicles come equipped with a primary yet effective anti-theft device.

It’s designed to protect your car by preventing the engine from starting.

However, this system may occasionally malfunction without warning.

Some Ford owners have reported instances where their anti-theft lights are off, and they are unable to start their vehicles.

In this article, we will guide you through the process of resetting the Ford Anti-Theft System.

It’s a straightforward procedure that you can do yourself.

It takes only about 15 minutes, and it helps ensure that your car remains protected from theft when you’re away.

At times, the Securilock anti-theft system can be overly vigilant.

Ford owners have shared instances where even the movement of a flying insect inside a locked vehicle can trigger the engine immobilization feature.

Additionally, loud noises, such as fireworks, have been known to set off car alarms, causing Securilock to shut down the engine.

Other circumstances that may result in an engine immobilization issue include:

  1. A dead car battery.
  2. Damage to one of the lock cylinders or exterior door handles.
  3. A low or dead transponder key battery.


What Does The Anti-theft System On A Ford Do?


Ford’s anti-theft system, known as Securilock┬«, is classified as a passive anti-theft system (PATS).

It automatically activates when you park your vehicle, remove the key, lock the doors, and close up.

Securilock responds to perceived threats by immobilizing the engine, preventing the vehicle from starting.

If an unauthorized, non-coded key is inserted into one of the door locks or the tailgate lock, the engine will immediately become immobilized.

While this is an effective deterrent against car theft, it can become problematic if the system engages due to a false alarm, leaving you with a non-starting vehicle.

Ford has incorporated advanced technology into its anti-theft system to address rising theft statistics associated with the brand.

In 2020, during the spike in car thefts in the U.S. caused by COVID-19, the most stolen vehicle was the 2006 Ford F-150, with a staggering 44,014 reported thefts that year.

Every new Ford vehicle comes equipped with two transponder keys or key fobs.

These keys are pre-programmed with embedded security codes that synchronize with the Securilock anti-theft system.

Any spare keys you possess for your Ford must be programmed in the same manner as the transponder keys to avoid triggering the anti-theft system.


Frequently Asked Questions


Will Disconnecting The Battery Reset The Anti-theft System?


Disconnecting the battery might lock you out of your car if your ECU controls the anti-theft system.

Similar to desktop computers and many other electronic devices, a brief disconnection of the battery cable will not completely reset your ECU because there may still be residual power in the circuits.


How Do You Know If You Need A New Battery?


If your engine requires more time to start, it may indicate a failing battery.

You might also notice unusual noises when turning the key or flickering lights, both of which are signs of a weakening battery.

It is advisable to have a professional inspect the starting system or replace the battery if necessary.
