2025 Ford F-350 Super Duty Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2025 Ford F-350 Super Duty does not support DIY on-board programming for its key fobs. Due to the advanced security systems and integrated immobilizer, a specialized scan tool is required to program new key fobs to your vehicle. This procedure typically involves linking the new fob to the vehicle's computer system.

Battery replacement

1. Locate the small release button or tab on the side or back of the key fob. Press or slide it to release the emergency key blade. Pull the emergency key blade out.
2. With the emergency key removed, you will see a small slot or indentation in the fob casing. Use a small, flat-head screwdriver or a coin to carefully pry open the two halves of the key fob.
3. Once opened, you will see the circuit board and the battery. Note the orientation of the old battery (usually positive side up).
4. Gently remove the old CR2450 battery.
5. Insert the new CR2450 battery, ensuring the positive (+) side is facing the correct direction, as noted in step 3.
6. Align the two halves of the key fob and press them firmly together until they click securely into place.
7. Reinsert the emergency key blade until it locks.

Where to buy a replacement fob

• Ford Dealership: This is often the most reliable option for purchasing an OEM replacement fob, ensuring full compatibility. However, it's typically the most expensive, with fobs alone costing upwards of $200-$350, plus separate programming and key cutting fees.
• Automotive Locksmith: Locksmiths can often provide and program OEM or high-quality aftermarket fobs for a lower cost than a dealership. They can usually cut the emergency key blade on-site as well. Expect to pay between $150-$300 for the fob and programming combined.
• Online Retailers (e.g., Amazon, eBay): You can find unprogrammed fobs for sale online, often at a significant discount (e.g., $50-$150). However, exercise caution. Ensure the FCC ID and part number match your original fob exactly. Remember, these fobs will still need to be programmed by a locksmith or dealership, and you'll need to get the emergency key blade cut separately. This option only saves you money on the fob itself, not the programming or cutting services.

If on-board programming isn't supported

As mentioned, the 2025 Ford F-350 Super Duty requires professional programming using a diagnostic scan tool. This means you will need to take your vehicle to a Ford dealership or a qualified automotive locksmith. The process is critical to ensure the new key fob is properly recognized by the vehicle's immobilizer system, which prevents the engine from starting without the correct programmed key.

Cost Expectations:

• Dealership: For a new fob, cutting the emergency key, and programming, you could be looking at a total cost ranging from $300 to $500+. Labor rates vary by region.
• Automotive Locksmith: Locksmiths generally offer more competitive pricing for the same services, often in the $200 to $400 range for a complete solution (fob, cut, and program).

The key blade integrated into your 2025 F-350 fob will need to be precision cut to match your vehicle's ignition and door locks. This can be done by a dealership or a specialist locksmith.
