2019 Ford F-250 Super Duty Key Fob Programming

Quick reference

Step-by-step on-board programming

Good news for 2019 F-250 owners: programming a new key fob's remote functions (lock, unlock, remote start) is a straightforward DIY process. This on-board procedure does not require any special tools. However, it's crucial to understand that this method only programs the remote control portion of the fob. The immobilizer chip, which is necessary to start the vehicle, must be programmed by a dealer or an automotive locksmith with a diagnostic scan tool.

This procedure requires you to have one existing, programmed key. If you have lost all your keys, you will need to contact a locksmith or dealer.

1. Enter the vehicle and ensure all doors are closed.
2. Insert the first programmed key into the ignition.
3. Cycle the ignition by turning the key from the OFF to the ON position eight times in rapid succession (within 10 seconds), ending in the ON position.
4. The door locks will cycle (lock and then unlock) to indicate that programming mode has been entered.
5. Within 8 seconds, press any button on the new, unprogrammed key fob. The door locks will cycle again to confirm that the new fob has been successfully programmed.
6. If you have additional fobs to program, press any button on each subsequent fob, waiting for the locks to cycle after each one.
7. Turn the ignition to the OFF position to exit programming mode. The locks will cycle one last time to confirm the end of the process.

Test all functions of your new fob(s) to ensure they are working correctly.

Battery replacement

Replacing the battery in your 2019 F-250 fob is a simple task.

1. Locate the small slot on the side or bottom of the key fob.
2. Use a small flathead screwdriver or a coin to gently pry the two halves of the fob apart.
3. Carefully remove the old battery, taking note of its orientation. The positive (+) side usually faces up.
4. Insert the new CR2032 battery in the same orientation.
5. Snap the two halves of the fob back together until they are securely clipped.

Where to buy a replacement fob

• Dealer: The most expensive option, but you are guaranteed an authentic OEM part. Expect to pay anywhere from $150 to $300 for the fob itself, plus an additional fee for programming the immobilizer chip (typically one hour of labor, $100–$150).
• Automotive Locksmith: A mobile locksmith can often provide and program a new key and remote for less than the dealership. They carry OEM and high-quality aftermarket fobs and have the necessary equipment to cut the emergency key and program the immobilizer on-site. Expect to pay $100–$250 for the fob and programming.
• Online Marketplaces (Amazon, eBay): You can find fobs for as little as $30–$80 online. While this is the cheapest route, there is a risk of receiving a low-quality or incorrect part. You will still need to pay a locksmith or dealer to cut the key and program the immobilizer chip, and many will not guarantee work on customer-supplied parts.

If on-board programming isn't supported

While the remote functions can be programmed at home, the most critical part of the key—the immobilizer transponder chip—cannot. Since the 1990s, Ford has equipped its keys with transponder chips as a theft deterrent. The chip in your 2019 F-250 key communicates with the vehicle's computer; if the code is not recognized, the engine will not start.

Programming this chip requires specialized diagnostic equipment that connects to the vehicle's OBD-II port. This is why a trip to an automotive locksmith or the Ford dealership is necessary. This service, often called "transponder key programming," is the primary reason for the additional cost beyond the hardware itself. Without this step, your new key will only be able to lock and unlock the doors.
