How to Change Subaru Key Fob

If you own a Subaru, knowing how to change your Subaru key fob is essential. Whether your key fob battery has died, the buttons are worn out, or you just want a new look, this guide will walk you through the process step-by-step. We’ll cover everything from choosing the right replacement to programming your new key fob.

Understanding Your Subaru Key Fob Options

Before diving into the replacement process, it’s essential to understand the different Subaru key fob options available.

OEM Key Fobs: These are original equipment manufacturer key fobs, identical to the one you received with your car. They are generally reliable but can be more expensive.
Aftermarket Key Fobs: These are manufactured by third-party companies and are often a more budget-friendly option. However, ensure you choose a reputable brand that guarantees compatibility with your Subaru model.

Can I Program a Subaru Key Fob Myself?

While programming some older Subaru key fobs might be possible at home, newer models often require specialized equipment and software. Dealerships have this equipment, and while it comes with a cost, it ensures the job is done correctly.

Finding the Right Key Fob for Your Subaru

Subaru offers a variety of key fobs, and choosing the right one depends on your model and year. You can find compatible key fob options through these avenues:

Your Subaru Dealership: This guarantees a perfect match but can be pricier.
Reputable Online Retailers: Websites like Amazon and eBay can be good sources, but meticulously verify compatibility with your Subaru’s year and model before purchasing.
Local Auto Parts Stores: Many auto parts stores carry a selection of key fobs. Again, confirming compatibility before buying is crucial.

What is the Key for Inside the Key Fob?

You’ll find a small key hidden inside your Subaru key fob. This is your mechanical key or valet key. This key is essential for various situations:

Dead Key Fob Battery: If your key fob battery dies, you can use the mechanical key to unlock your car door manually.
Valet Parking: When using valet parking, you can give the valet the mechanical key and keep your key fob. This limits their access to your vehicle.

How to Replace the Battery on a Subaru Key Fob

A dying key fob battery is often the culprit behind key fob malfunctions. Here’s how to change it:

Locate the Battery Compartment: Consult your owner’s manual for the exact location on your specific key fob model. It’s usually on the back.
Open the Battery Compartment: Some Subaru key fobs require a small flat-head screwdriver to pry open the battery compartment, while others have a sliding mechanism.
Identify the Battery Type: Most Subaru key fobs use a CR2032 battery.
Replace the Battery: Carefully remove the old battery and insert the new one, ensuring the positive (+) side faces up.
Close the Battery Compartment: Securely close the compartment.
Test Your Key Fob: Check if your key fob functions correctly by locking and unlocking your car.
