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.
- First, remove the mechanical key from the bottom of the fob.
- 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.
- Once the fob is open, you will see the battery. It is a CR2450 coin cell battery.
- Carefully remove the old battery and insert the new one, making sure the positive side is facing up.
- 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.
