2022 Subaru Forester — Key Fob Programming

Quick reference

Step-by-step on-board programming

Unfortunately, the 2022 Subaru Forester does not support on-board, or do-it-yourself (DIY), key fob programming. This is a significant departure from older vehicles that might have allowed programming through a series of key turns and button presses. Modern Subarus, including the 2022 Forester, utilize a sophisticated encrypted immobilizer system for enhanced security. To pair a new key fob with your vehicle, a specialized diagnostic scan tool and proprietary software are required to access the car's computer and register the new fob. This means you will need to have your key fob programmed by a Subaru dealership or a qualified automotive locksmith.

Battery replacement

Replacing the battery in your 2022 Subaru Forester key fob is a simple task you can do at home. Here’s how:

1. Release the emergency key: Press the small silver button on the back of the fob to release the physical emergency key.
2. Open the fob: Use the emergency key or a small flathead screwdriver to gently pry the two halves of the fob apart. There is a small indentation where the key came out that you can use for leverage.
3. Remove the old battery: The fob will open up like a clamshell. The CR2032 battery is located on one side. Note the orientation of the positive (+) and negative (-) sides.
4. Insert the new battery: Slide the new CR2032 battery into place, ensuring it is oriented correctly.
5. Reassemble the fob: Snap the two halves of the fob back together until they click, and re-insert the emergency key.

Where to buy a replacement fob

You have several options for purchasing a new key fob, each with its own pros, cons, and cost implications:

• Subaru Dealership: This is the most expensive option, often ranging from $200 to $400 for the fob and programming. The main advantage is that you are guaranteed to get a genuine OEM part that is programmed correctly.
• Automotive Locksmith: A professional locksmith can typically provide and program a new fob for a lower cost than the dealer, usually between $150 and $300. Mobile locksmiths offer the added convenience of coming to your location. They can often source OEM or high-quality aftermarket fobs.
• Online (Amazon, eBay, etc.): You can find replacement fobs online for as little as $50 to $100. However, you are buying just the hardware. You will still need to pay a locksmith or dealer to cut the emergency key blade and, most importantly, program the fob to your vehicle. Be cautious with online sellers and ensure the FCC ID (HYQ14AHK) matches your existing fob.

If on-board programming isn't supported

As mentioned, the 2022 Forester requires professional programming. This is because the key fob is more than just a remote for your door locks; it contains a transponder chip that communicates with the vehicle's immobilizer system. This is a critical security feature that prevents the engine from starting unless a recognized transponder is present. Without the correct diagnostic equipment, it is impossible to register the unique code of the new transponder chip with your car's computer. This is why you cannot program the fob yourself. When you pay for professional programming, you are paying for the technician's access to and expertise with these specialized scan tools, which can cost thousands of dollars.
