    Step-by-step on-board programming

    Unfortunately, the 2015 Subaru Outback does not have an on-board programming procedure for new key fobs. This is because the key fob is also linked to the immobilizer system, which requires a specialized scan tool to program. This is a security measure to prevent unauthorized key copying.

    To program a new key fob, you will need to take your vehicle to a Subaru dealership or a qualified automotive locksmith. They have the necessary equipment and software to program the new key to your vehicle's computer.

    Battery replacement

    Replacing the battery in your 2015 Subaru Outback key fob is a simple process you can do at home.

    1. Open the fob: Look for a small slot on the side of the key fob. Use a small flathead screwdriver or a coin to gently pry the two halves of the fob apart.
    2. Remove the old battery: The battery is a CR2032 coin cell. Take note of the battery's orientation (+ side up or down) before removing it.
    3. Insert the new battery: Slide the new CR2032 battery into place, making sure it is oriented correctly.
    4. Close the fob: Snap the two halves of the key fob back together until you hear a click.

    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 around $200-$300 for the fob and another $100-$150 for programming.
    • Automotive Locksmith: A locksmith can often provide you with a new key fob and program it for less than the dealership. They may offer either OEM or high-quality aftermarket fobs. Expect to pay around $150-$250 for the fob and programming.
    • Online Retailers (Amazon, eBay): You can find a wide variety of aftermarket key fobs online for as little as $50. However, the quality can vary, and you will still need to have the fob programmed by a dealership or locksmith. Be sure to match the FCC ID (HYQ14AHK) to ensure compatibility.

    If on-board programming isn't supported

    As mentioned, the 2015 Subaru Outback requires a specialized scan tool to program new key fobs. This is because the key contains a transponder chip that communicates with the vehicle's immobilizer system. The transponder chip is a security feature that prevents the car from starting if the correct key is not present. When a new key is programmed, the scan tool registers the unique code of the new transponder chip with the vehicle's computer.
