Losing or damaging your car key fob can be a stressful and costly experience. Traditionally, getting a replacement programmed meant a trip to the dealership and a hefty bill. However, with the advent of tools like FORScan, Ford owners now have the power to program key fobs themselves, saving both time and money. This guide will walk you through the process of Forscan Key Fob Programming, making it accessible even if you’re not a seasoned mechanic.
What You Need for FORScan Key Fob Programming
Before you begin, ensure you have the necessary equipment and software. This DIY approach requires a few key items:
- FORScan Software: This powerful software is specifically designed for Ford, Lincoln, and Mercury vehicles, offering in-depth diagnostics and customization options. You can download FORScan from their official website. A free trial is available, which is often sufficient for key programming.
- Compatible OBDII Adapter: This adapter connects your vehicle’s diagnostic port to your computer. FORScan recommends specific adapters for optimal performance and compatibility. A reliable wired adapter is generally preferred for programming tasks to ensure a stable connection. Bluetooth adapters can sometimes be problematic.
- New Key Fob: Purchase a new, compatible key fob for your Ford vehicle. Ensure it’s the correct type and frequency for your car’s model and year. Reputable online retailers or automotive locksmiths are good sources for key fobs.
- Laptop Computer: You’ll need a laptop running Windows to install and operate the FORScan software.
- Existing Working Key (if available): While this guide focuses on programming with only one key, having a working key can sometimes simplify the process and is required for certain procedures.
Step-by-Step Guide to FORScan Key Fob Programming
This procedure outlines how to program an additional key fob using FORScan, even if you only have one working key. Always double-check the FORScan documentation and your vehicle’s repair manual for the most accurate and up-to-date instructions specific to your Ford model.
-
Prepare FORScan and OBD Adapter:
- Install the FORScan software on your laptop and launch the application.
- Connect your OBDII adapter to your laptop via USB and plug the other end into your Ford’s OBDII port. This port is typically located under the steering wheel column.
-
Enter Ignition Mode:
- With your working key fob (if you have one) inside the vehicle, enter ignition mode. For vehicles with push-button start, this usually involves pressing the start button twice without pressing the brake pedal. For traditional key ignition, turn the key to the “ON” position without starting the engine.
-
Locate Key Programming Slot:
- Identify the key programming slot inside your Ford. For many models like the Ford Flex, this slot is located inside the center console. Refer to your owner’s manual for the exact location as it can vary between models. Place the new key fob into this slot, ensuring it is properly oriented as described in your manual (typically key ring slot towards the rear and buttons facing the passenger side).
-
Connect to FORScan:
- In the FORScan software, click the “Connect” button, usually located at the bottom of the window. Allow FORScan to establish a connection with your vehicle and load all the necessary modules. This process may take a few moments.
-
Access Service Procedures:
- Once connected, navigate to the “Service Procedures” section within FORScan. This is often represented by a wrench icon on the left-hand side menu.
-
Select RFA – PATS Programming:
- Within the Service Procedures, locate and select the module labeled “RFA – PATS Programming”. RFA stands for Radio Frequency Amplifier, and PATS is Ford’s Passive Anti-Theft System. Modern Ford key programming often involves the RFA module.
-
Initiate “Program a new key” Procedure:
- Follow the prompts within FORScan. You may be asked to switch the MS/HS switch on your OBD adapter if you have a dual-CAN adapter. Select the option to “Program a new key” or a similarly worded function. Click the “Start” or “Play” button within FORScan to begin the procedure.
-
Security Wait Time:
- FORScan will initiate a security access process which requires a timed wait, typically around 10 minutes. This is a security measure to prevent unauthorized key programming. Remain patient and do not interrupt the process.
-
Complete Programming:
- After the wait time expires, FORScan will prompt you to proceed. Click “OK” or continue as instructed by the software. At this point, the new key fob should be programmed to your vehicle. FORScan may ask you to turn the ignition off and then on again to finalize the process.

Troubleshooting Tips for FORScan Key Fob Programming
While FORScan simplifies the process, you might encounter some challenges. Here are common troubleshooting tips based on user experiences:
- Adapter Compatibility: Ensure your OBDII adapter is fully compatible with FORScan and supports the necessary protocols for key programming on your Ford model. The error message “adapter is not compatible” (as seen in the forum) indicates a potential issue with your adapter. Consider using a recommended adapter like the OBDLink EX for optimal results.
- Stable Connection: A reliable wired adapter is generally more stable than Bluetooth for programming. Maintain a stable connection throughout the entire process.
- Battery Voltage: Ensure your vehicle’s battery has sufficient voltage. Low voltage can sometimes interrupt the programming process. Consider using a battery maintainer during programming, especially if the process takes longer than expected.
- Door Closure: Some users have reported that keeping the doors closed throughout the programming process is crucial. Avoid opening any doors during the security wait and programming phases.
- “Spare Keys Programmable: Enabled” Message: If you encounter a message about “Spare keys programmable: Enabled,” it might be a prompt to either enable or disable this function. In most cases, it should be enabled for programming spare keys. If you are unsure, proceed with the default option or consult the FORScan documentation.
- Error Codes: If the programming fails, FORScan may display error codes. Research these codes (like DTC B10D7:05-48 mentioned in the forum) to understand the specific issue and troubleshoot accordingly. Online Ford forums and FORScan communities can be valuable resources for deciphering error codes.
- Two Keys Required: In some cases, particularly after erasing keys or performing certain programming functions, you may need to program at least two keys before the vehicle will start. This is a security feature.
Conclusion
Programming your Ford key fob with FORScan offers a practical and cost-effective alternative to dealership programming. By following these steps carefully and taking note of the troubleshooting advice, you can successfully program new key fobs and regain control over your vehicle’s access system. Remember to always consult your vehicle-specific repair information and the FORScan documentation for the most accurate guidance. Empower yourself with DIY car maintenance and enjoy the savings and satisfaction of managing your vehicle’s key programming at home.
