2020 Subaru Outback Key Fob Programming

Quick reference

Step-by-step on-board programming

Unfortunately, the 2020 Subaru Outback does not offer a do-it-yourself (DIY) or on-board programming procedure for new key fobs. This is due to the advanced security of the immobilizer system, which requires a proprietary Subaru-specific scan tool to pair a new key to the vehicle's computer.

This measure is in place to prevent vehicle theft and ensures that only authorized keys can start the engine. Therefore, you will need to have your new key fob programmed by a Subaru dealership or a qualified automotive locksmith.

Battery replacement

Replacing the battery in your 2020 Subaru Outback key fob is a simple process you can do at home.

1. Release the emergency key: Press the small silver button on the back of the fob to release the physical key.
2. Open the fob: Use the emergency key or a small flathead screwdriver to gently pry open the two halves of the key fob. There is a small slot where the key came out of that you can use for leverage.
3. Replace the battery: The fob uses a CR2032 battery. Note the orientation of the old battery before removing it, and make sure to install the new one in the same way (positive side up).
4. Reassemble the fob: Snap the two halves of the fob back together and reinsert the emergency key.

Where to buy a replacement fob

• Subaru Dealership: This is the most expensive option, but you are guaranteed to get a genuine OEM key fob that is compatible with your vehicle. Expect to pay anywhere from $200 to $400 for the fob and programming.
• Automotive Locksmith: A qualified locksmith can often source OEM or high-quality aftermarket fobs for a lower price than the dealership. They also have the necessary tools to program the fob to your Outback. This can be a more convenient option as many locksmiths are mobile and can come to you. Costs can range from $150 to $300.
• Online Retailers (Amazon, eBay): You can find a wide variety of aftermarket key fobs online at a much lower price, often under $100. However, the quality can be inconsistent, and you will still need to find a locksmith or dealer to program the fob for you. Be sure to match the FCC ID (HYQ14AHK) to ensure compatibility.

If on-board programming isn't supported

As mentioned, the 2020 Outback requires professional programming. The key fob contains a transponder chip that communicates with the car's immobilizer system. Without proper programming, the car will not start, even if the key is cut to match the door locks. This transponder is a critical security feature. When a locksmith or dealer programs a new key, they are essentially registering its unique transponder ID with the vehicle's computer, authorizing it to start the engine.
