how to disable subaru key fob

2 min read 16-01-2025

Losing your Subaru key fob, or needing to temporarily disable it, can be a stressful situation. Fortunately, disabling your Subaru key fob is usually a straightforward process, though the exact steps vary slightly depending on your model year and whether you have a standard key fob or a smart key system. This guide will walk you through the process for various Subaru models.

Understanding Your Subaru Key System

Before we begin, it's important to understand what type of key system your Subaru has. There are generally two types:

Standard Key Fob: This type has buttons for locking, unlocking, and panic features. You'll typically need to insert a physical key into the ignition to start the car.
Smart Key System (Push-to-Start): This system uses proximity sensors. You can unlock and start the car without physically inserting a key.

Disabling a Standard Subaru Key Fob

Disabling a standard Subaru key fob usually involves removing the key fob's battery. This will prevent it from sending signals to your vehicle.

Steps:

Locate the Battery: The battery compartment is typically located on the back of the key fob. You might need a small flathead screwdriver or a similar tool to pry it open.
Remove the Battery: Carefully remove the battery from the compartment.
Reassemble the Key Fob (if necessary): Once the battery is removed, you can reassemble the fob.
Test the Key Fob: Attempt to lock or unlock your Subaru using the disabled key fob. It should no longer function.

Important Note: This method only disables the remote functions. The physical key portion will still work in the ignition.

Disabling a Subaru Smart Key Fob (Push-to-Start)

Disabling a smart key system requires different steps, as the fob's battery removal alone might not fully disable all functions. This often involves registering the key fob again, or in some cases, contacting a Subaru dealership. Consult your owner's manual for specific instructions relevant to your model year.

General Steps (May Vary by Model):

The process for a Subaru smart key is far more complex and often requires the use of the vehicle's settings menu and a specific pairing procedure. Detailed instructions will be found in the owner's manual. Contacting a Subaru dealership or certified mechanic is highly recommended for this process.

What to Do if Your Key Fob is Lost or Stolen

If your key fob is lost or stolen, disabling it is crucial to prevent unauthorized access to your vehicle. Immediately:

Change your locks: This is the most critical step to secure your Subaru.
Contact your Subaru Dealership: They can help reprogram your car's system and potentially disable the lost fob's functionality.
Report the Loss or Theft to the Police: This is essential for insurance purposes and preventing potential misuse.

Troubleshooting

If you're still experiencing issues after following these steps, consult your owner's manual or contact a Subaru dealership. They can diagnose the problem and provide expert assistance.

Conclusion

Disabling your Subaru key fob, whether a standard or smart key system, can be done, though the methods vary. Remember to always prioritize your vehicle's security, and if you're having trouble, don't hesitate to seek professional help. Remember to always consult your owner's manual for model-specific instructions. Keeping your Subaru secure is key!
