Step-by-step on-board programming
Unfortunately, the 2020 Ford F-150 does not support on-board programming for new key fobs. This is due to the advanced security systems in modern vehicles, which require specialized equipment to program new keys and prevent theft. You will need to take your vehicle to a Ford dealership or a qualified automotive locksmith to have a new key fob programmed.
Battery replacement
Replacing the battery in your 2020 Ford F-150 key fob is a simple process that you can do at home.
- First, you will need to purchase a new CR2450 battery.
- Once you have the new battery, you will need to open the key fob. To do this, simply pry the two halves of the key fob apart with a small flathead screwdriver.
- Once the key fob is open, you will see the old battery. Carefully remove the old battery and insert the new one, making sure that the positive side of the battery is facing up.
- Once the new battery is in place, simply snap the two halves of the key fob back together.
Where to buy a replacement fob
There are a few different places where you can buy a replacement key fob for your 2020 Ford F-150.
- Ford dealership: The dealership is the most expensive option, but it is also the most convenient. You can expect to pay around $200 for a new key fob from the dealership.
- Automotive locksmith: A locksmith is a good option if you want to save some money. You can expect to pay around $150 for a new key fob from a locksmith.
- Amazon: Amazon is the cheapest option, but it is also the most risky. You can find key fobs for as little as $50 on Amazon, but there is no guarantee that they will be compatible with your vehicle.
If on-board programming isn't supported
As mentioned above, the 2020 Ford F-150 does not support on-board programming. This is because the vehicle is equipped with an immobilizer transponder, which is a security feature that prevents the vehicle from being started without the correct key. In order to program a new key fob, you will need to have the immobilizer transponder programmed by a Ford dealership or a qualified automotive locksmith.
