2019 Ford F-150 Key Fob Programming

Quick reference

Step-by-step on-board programming

Unfortunately, the 2019 Ford F-150 does not support DIY on-board programming for its key fobs. The sophisticated security systems in modern Ford vehicles, including the F-150, require a specialized diagnostic scan tool to program new key fobs. This process involves syncing the new fob with the vehicle's immobilizer system, which can only be done by a Ford dealership or a professional automotive locksmith.

Attempting to program a new key fob without the proper equipment can lead to issues with your vehicle's security, potentially preventing it from starting or even bricking the new fob. Therefore, it's crucial to rely on trained professionals for this service.

Battery replacement

Replacing the battery in your 2019 Ford F-150 key fob is a straightforward process:

1. Locate the small release button or switch on the side or bottom of the key fob. Press it to release the emergency key blade. Pull the key blade out. The emergency key is typically used to open the door manually if the fob battery dies.
2. With the emergency key removed, you'll see a small slot or indentation where the key blade was. Use a small flathead screwdriver or a coin to gently pry open the two halves of the key fob casing.
3. Carefully separate the two halves. You will see the circuit board and the coin-cell battery.
4. Note the orientation of the old battery (usually positive side up). Gently pry out the old CR2450 battery.
5. Insert the new CR2450 battery, ensuring that the positive (+) side is facing in the same direction as the old battery.
6. Align the two halves of the key fob casing and firmly press them back together until they snap securely into place.
7. Reinsert the emergency key blade into its slot.

Test the functionality of your key fob with the new battery.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2019 Ford F-150, you have several options, each with pros and cons:

• Ford Dealership:
  • Pros: Guaranteed genuine OEM part, often comes with a warranty, and they have the necessary programming equipment on-site.
  • Cons: Most expensive option. Expect to pay anywhere from $200-$400 for the fob itself, plus an additional $100-$200 for programming.
• Automotive Locksmith:
  • Pros: Often more affordable than a dealership for both the fob and programming. Many mobile locksmiths can come to you, saving you a trip. They typically offer both OEM and quality aftermarket options.
  • Cons: Quality of aftermarket fobs can vary, so ensure the locksmith uses reputable brands. Cost for an aftermarket fob and programming could be $150-$300.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Cheapest option for the key fob itself. You can find both OEM and aftermarket fobs.
  • Cons: You still need to find a way to get it programmed, which will be an additional cost. There's a higher risk of purchasing a counterfeit or incompatible fob. Programming costs will be separate, adding $100-$200 from a dealer or locksmith. Always verify the FCC ID and part number before purchasing.

If on-board programming isn't supported

Since on-board programming is not supported for your 2019 Ford F-150, you will need to pay for professional programming services. Here's what to expect regarding costs and the immobilizer system:

Cost Expectations:

• Dealership: As mentioned, expect to pay a total of $300-$600 for a new OEM fob and programming.
• Locksmith: A locksmith can often provide a new key fob (OEM or quality aftermarket) and programming for $150-$350. This is typically the most cost-effective solution when considering both parts and labor.

Immobilizer Transponder:

Your 2019 Ford F-150 utilizes an advanced immobilizer transponder system. This system consists of a chip embedded within the key fob that communicates with the vehicle's computer. Without proper communication between the transponder and the vehicle, the engine will not start, even if the key blade fits the ignition. When a new key fob is programmed, the transponder chip's unique code is registered with the vehicle's immobilizer system. This is why professional equipment is required, as it can access and modify the vehicle's security protocols to accept the new fob.
