Unlock Your Subaru: Quick Tips to Get Out of Anti Theft Mode


Understanding Anti Theft Mode In Subaru

Subarus are equipped with a security feature called anti theft mode, which is designed to protect your vehicle from unauthorized use or theft. This mode is activated when the system detects a potential threat, such as an attempted break-in or when there is a key programming issue.

In this section, we will explore what anti theft mode is, how it works in subaru vehicles, common reasons for activation, and how to identify if your subaru is in anti theft mode.

What Is Anti Theft Mode?

  • Anti theft mode is a security feature in subaru vehicles that prevents unauthorized access and use.
  • It is specifically designed to protect your vehicle from theft or other security-related issues.
  • When anti theft mode is activated, certain functions of your subaru, such as the ignition, will be disabled.

How Does Anti Theft Mode Work In Subaru?

  • Anti theft mode in subaru relies on the vehicle’s immobilizer system, which communicates with the key fob or transponder key.
  • The immobilizer system uses a unique code that is electronically transmitted between the key and the vehicle’s engine control unit (ecu).
  • If the immobilizer system recognizes a valid key code, the vehicle will start normally. However, if an incorrect or unrecognized key code is detected, anti theft mode is triggered, disabling the ignition and other key functions.

Common Reasons For Activating Anti Theft Mode

  • Incorrect key programming: If the key fob or transponder key is not properly programmed or has been reprogrammed, the vehicle may enter anti theft mode.
  • Suspected theft or tampering: If the vehicle’s security system detects suspicious activity, such as an attempted break-in or unauthorized key usage, it may activate anti theft mode as a precautionary measure.
  • Battery replacement or disconnect: In some cases, disconnecting the battery or replacing it without taking the necessary precautions can trigger the anti theft mode.
  • Malfunctioning immobilizer system: If there is an issue with the immobilizer system itself, such as a faulty sensor or wiring problem, it can mistakenly activate anti theft mode.

How To Know If Your Subaru Is In Anti Theft Mode

  • Look for the security indicator light: When your subaru is in anti theft mode, a security indicator light on the dashboard will typically flash or stay illuminated.
  • Check for warning messages: Some subaru models display specific warning messages on the instrument cluster or infotainment screen when anti theft mode is activated.
  • Attempt to start the vehicle: If your subaru is in anti theft mode, the engine will not start or may only crank without actually igniting.

Remember, if your subaru is stuck in anti theft mode or you are unsure how to resolve the issue, it is recommended to consult your vehicle’s owner’s manual or contact a subaru dealership for assistance. By understanding anti theft mode and its activation triggers, you can better protect your subaru and ensure its security.

Quick Tips To Disable Anti Theft Mode

If you have a subaru that is stuck in anti-theft mode, don’t worry—there are several quick and easy steps you can take to disable it. In this section, we will discuss some simple solutions to get your subaru out of anti-theft mode and back on the road.

Check The Key Fob Battery

One of the first things you should check when attempting to disable the anti-theft mode is the battery in your key fob. A weak or dead battery can sometimes trigger the anti-theft mode. Here’s what you can do:

  • Replace the battery in your key fob if it’s old or depleted.
  • Make sure the battery is inserted correctly, following the polarity markings.

Restart The Vehicle’S System

Sometimes, a simple restart of your vehicle’s system can successfully disable the anti-theft mode. Follow these steps:

  • Turn off the vehicle’s ignition and remove the key.
  • Wait for a few minutes to allow the system to reset.
  • Reinsert the key and start the vehicle.

Disconnect And Reconnect The Car Battery

If restarting the system didn’t work, another option is to disconnect and reconnect the car battery. Here’s how you can do it correctly:

  • Park your subaru in a safe and well-ventilated area.
  • Locate the negative terminal (-) on the car battery and use a wrench to loosen the bolt.
  • Remove the negative cable from the battery and wait for approximately 15 minutes.
  • Reconnect the negative cable to the battery and tighten the bolt securely.

Resetting The Vehicle’S Computer System

If all else fails, you can try resetting the vehicle’s computer system to disable the anti-theft mode. Follow these steps:

  • Turn off the vehicle’s ignition and remove the key.
  • Locate the fuse box and find the fuse labeled “ecu” or “ecm.”
  • Remove the fuse for at least 10 seconds before reinstalling it.
  • Insert the key and start the vehicle.

Remember, these quick tips are general suggestions and may not resolve every situation. If the anti-theft mode persists, it may be necessary to consult your subaru dealership or a qualified mechanic for further assistance.
