2017 Ford F-350 Super Duty Key Fob Programming

Quick reference

Step-by-step on-board programming

This vehicle supports on-board programming for adding a new key, provided you already have two previously programmed keys. If you only have one or no working keys, you will need to see a dealer or an automotive locksmith to have a new key programmed.

To program a new key fob (with integrated key head):

1. Insert the first programmed key into the ignition.
2. Turn the ignition from OFF to ON. Wait for three seconds.
3. Turn the ignition back to OFF and remove the key.
4. Within five seconds, insert the second programmed key into the ignition.
5. Turn the ignition from OFF to ON. Wait for three seconds.
6. Turn the ignition back to OFF. The vehicle is now in programming mode.
7. Within ten seconds, insert the new, unprogrammed key into the ignition.
8. Turn the ignition from OFF to ON. Wait for five seconds for the new key to be programmed.
9. Turn the ignition to OFF and remove the key.

The new key should now be programmed. Test both the remote functions (lock, unlock) and the immobilizer (start the engine) to confirm.

Battery replacement

Replacing the battery in your 2017 F-350 key fob is a simple process:

1. Locate the small slot on the side 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 CR2032 battery, noting its orientation.
4. Insert the new CR2032 battery, ensuring the positive (+) side is facing the correct direction.
5. Snap the two halves of the key fob back together until they click securely.

Where to buy a replacement fob

• Dealer: The most expensive option, but guarantees an authentic OEM part. Expect to pay $150-$250 for the fob and another $100-$150 for programming.
• Automotive Locksmith: A more cost-effective choice. Locksmiths can often source OEM or high-quality aftermarket fobs for less than the dealer and charge a lower programming fee. This is your best option if you have lost all your keys. Expect to pay $100-$200 for the fob and programming.
• Amazon/Online: The cheapest way to get a replacement fob, with prices ranging from $20-$60. However, quality can be inconsistent, and you still need to have the key blade cut and the fob programmed. This is a good DIY option if you already have two working keys.

If on-board programming isn't supported

On-board programming for the 2017 Ford F-350 is only possible if you have two existing, programmed keys. If you have only one key (or none), the vehicle's computer system must be accessed with a specialized diagnostic scan tool to program a new key. This is because the key contains an immobilizer transponder chip that needs to be electronically paired with the truck.

An automotive locksmith or a Ford dealership has the necessary equipment to perform this service. The tool connects to the vehicle's OBD-II port and allows the technician to add new keys to the immobilizer system. This is a security measure to prevent unauthorized key duplication. Cost for this service typically ranges from $100 to $250, in addition to the cost of the key itself.
