    Step-by-step on-board programming

    Unfortunately, the 2020 Ford F-350 Super Duty does not support on-board programming for new key fobs. This is because the vehicle is equipped with a sophisticated immobilizer system that requires specialized diagnostic equipment to program new keys. This measure is in place to prevent vehicle theft. Therefore, you will need to have a professional locksmith or a Ford dealership program the new key fob for you.

    Battery replacement

    Replacing the battery in your 2020 Ford F-350 Super Duty key fob is a simple process that you can do at home.

    1. First, remove the mechanical key from the bottom of the fob.
    2. Then, use a small flathead screwdriver to carefully pry the two halves of the key fob apart. There is a small indentation at the bottom of the fob where you can insert the screwdriver.
    3. Once the fob is open, you will see the battery. It is a CR2450 coin cell battery.
    4. Carefully remove the old battery and insert the new one, making sure the positive side is facing up.
    5. Snap the two halves of the fob back together and reinsert the mechanical key.

    Where to buy a replacement fob

    There are a few options for buying a replacement key fob for your 2020 Ford F-350 Super Duty.

    • Dealer: The most expensive option, but you can be sure you are getting a genuine OEM key fob that will be programmed correctly. Expect to pay around $300 or more for the fob and programming.
    • Locksmith: A more affordable option than the dealer, and many locksmiths can program the key fob for you. You can expect to pay around $200 for the fob and programming.
    • Amazon: The cheapest option, but you will need to make sure you are buying a quality aftermarket fob that is compatible with your vehicle. You will also need to have the fob programmed by a locksmith or dealer. Expect to pay around $50 for the fob itself.

    If on-board programming isn't supported

    As mentioned, on-board programming is not an option for the 2020 Ford F-350 Super Duty. This is due to the advanced immobilizer system that is designed to protect your vehicle from theft. The immobilizer system uses a transponder chip in the key fob to communicate with the vehicle's computer. If the computer does not recognize the transponder chip, the vehicle will not start. Programming a new key fob requires a specialized scan tool that can access the vehicle's computer and program the new transponder chip. This is why you will need to go to a dealer or a locksmith to have a new key fob programmed.
