Losing or damaging your car key fob can be a stressful and costly experience. Ford key fobs, while technologically advanced for convenience and security, can be expensive to replace and program at a dealership. Fortunately, for Ford owners looking for a more affordable and hands-on solution, programming a new key fob at home is possible using software called FORScan and an OBD adapter. This guide will walk you through the process of Programming A Ford Key Fob yourself, saving you time and money.
What You’ll Need to Program Your Ford Key Fob
Before you begin, ensure you have the necessary equipment and software. Programming a Ford key fob yourself requires a few key items:
-
FORScan Software: FORScan is a powerful, free (with extended license options) software application designed specifically for Ford, Mazda, Lincoln, and Mercury vehicles. It allows you to access and modify various vehicle modules, including the Remote Function Actuator (RFA) module responsible for key fob programming. You can download FORScan from forscan.org.
-
OBD-II Adapter: An OBD-II (On-Board Diagnostics II) adapter is essential to connect your vehicle’s computer to your laptop or PC running FORScan. FORScan recommends specific adapters for optimal performance and compatibility. A reliable option is the OBDLink EX USB adapter, known for its compatibility and speed with FORScan.
-
New Ford Key Fob: You’ll need a new, compatible Ford key fob. Ensure you purchase the correct key fob for your Ford model and year. Reputable online retailers specializing in car remotes are good sources for purchasing replacement fobs.
-
Existing Working Key (If Available): While this guide focuses on programming a key fob even if you only have one working key, having at least one functioning key fob will be necessary to initiate the programming procedure using FORScan.
Once you have gathered these items, you are ready to begin the programming process.
Step-by-Step Guide to Programming Your Ford Key Fob Using FORScan
The following steps outline the procedure to program a new Ford key fob using FORScan. It is crucial to follow these steps carefully for successful programming.
Preparation
-
Install FORScan Software: Download and install the FORScan software on your Windows-based laptop or PC. Follow the installation instructions provided on the FORScan website.
-
Vehicle Ignition: Get your Ford vehicle ready for programming. The procedure generally requires the vehicle to be in ignition mode, meaning the electrical system is on, but the engine is not running. To achieve this, typically press the start button twice without pressing the brake pedal.
-
Key Fob Placement: Locate the key programming slot inside your Ford. In many Ford models, including the Ford Flex, this slot is located inside the center console. Refer to your vehicle’s owner manual for the exact location and orientation of the key fob in the slot. Generally, the key ring slot should face the rear, and the buttons should face the passenger side.
Connecting FORScan
-
Connect OBD-II Adapter: Plug your OBD-II adapter into the OBD-II port located beneath the steering wheel on your Ford.
-
Launch FORScan and Connect: Open the FORScan software on your computer and press the “Connect” button, usually located at the bottom of the window. FORScan will establish a connection with your vehicle’s modules.
-
Module Loading: Wait for FORScan to load all the vehicle modules. This process may take a few moments.
Initiating PATS Programming
-
Access Service Procedures: Once the modules are loaded, click on the “Wrench” icon on the left-hand side menu in FORScan. This icon represents “Service procedures.”
-
Select RFA – PATS Programming: In the Service Procedures menu, locate and select the module labeled “RFA – PATS programming.” RFA stands for Remote Function Actuator, and PATS is the Passive Anti-Theft System.
-
Adapter Switch (If Required): Some OBD adapters, especially those with MS/HS CAN switches, may require you to switch between MS-CAN and HS-CAN during the programming process. FORScan will prompt you if a switch is necessary. Follow the on-screen instructions carefully.
-
Select “Program a new key”: Choose the option to “Program a new key” within the RFA – PATS programming menu.
Programming the New Key
-
Security Wait Time: Initiating key programming usually requires a security wait time. This is a security measure implemented by Ford to prevent unauthorized key programming. FORScan will display a timer, typically for 10 minutes. Do not interrupt this process.
-
Wait and Select OK: After the 10-minute wait period expires, FORScan will prompt you to proceed. Select “OK” to continue the key programming process.
-
Key Fob Programming Completion: FORScan will communicate with your vehicle to program the new key fob. Follow any further on-screen prompts from FORScan. Once completed, FORScan should indicate that the key programming was successful.

Troubleshooting Tips Based on User Experiences
While the FORScan key programming procedure is generally straightforward, users may encounter issues. Here are some troubleshooting tips based on experiences shared by Ford owners:
- Programming Failure: If the programming process fails, ensure you have followed each step precisely. Double-check the key fob placement in the programming slot and the OBD adapter connection.
- Adapter Compatibility: Some generic OBD adapters might not be fully compatible with FORScan or all Ford vehicle modules. If you encounter errors or communication issues, consider using a FORScan-recommended adapter like the OBDLink EX. The error message “adapter is not compatible with my car” suggests cable incompatibility.
- Key Type and Compatibility: Verify that the new key fob you purchased is indeed compatible with your Ford vehicle’s year, model, and trim level. Using an incompatible key fob will prevent successful programming.
- Battery Voltage: Maintain stable battery voltage throughout the programming process. Low battery voltage can sometimes interrupt the programming. Ensure your vehicle’s battery is in good condition or consider using a battery maintainer during the procedure, especially if you are working with the ignition in “ON” mode for an extended period.
- Door Interruption: Some users have noted that opening the car door during the security wait time might interrupt the programming. Avoid opening the doors during the key programming procedure.
- Two Keys Required to Start: In some cases, especially after erasing keys or during initial programming, you might need to program at least two keys before the vehicle will start. If your car turns on but doesn’t start after programming one key, proceed to program a second key immediately.
- “Spare Keys Programmable: Enabled” Message: If you encounter a message like “spare keys programmable: Enabled” and the programming restarts unexpectedly, it might indicate an issue with the key fob, adapter, or programming process. Ensure you are using a compatible key fob and a reliable OBD adapter.
- CANBUS Errors: CANBUS errors during programming can also point to adapter incompatibility or communication issues. A high-quality, FORScan-recommended adapter is crucial for reliable communication.

Conclusion
Programming a Ford key fob using FORScan offers a viable and cost-effective alternative to dealership programming. By carefully following the steps outlined in this guide and using the correct equipment, you can successfully program a new key fob yourself. While some troubleshooting might be necessary, the savings and sense of accomplishment from DIY key fob programming make it a worthwhile endeavor for Ford owners. Remember to consult your vehicle’s owner’s manual and the FORScan documentation for any specific instructions or recommendations related to your Ford model.
