Losing or damaging a car key fob can be a real headache, and the cost of getting a replacement and having it programmed by a dealership or locksmith can be surprisingly high. As a seasoned auto repair content creator for keyfobx.com, I understand the frustration and the desire to find a more affordable solution. In this guide, I’ll walk you through how to reprogram your Honda key fob yourself using a readily available tool, potentially saving you a significant amount of money and time.
What You’ll Need to Reprogram Your Honda Key Fob
Before we dive into the reprogramming process, let’s gather the necessary tools and parts. This method utilizes an OBD-II scanner, specifically the Autel MaxiAP200, which is a cost-effective device capable of performing many dealer-level diagnostic and programming functions. Here’s what you’ll need:
- A new, compatible Honda Key Fob: You can purchase these online from retailers like eBay or Amazon. Ensure it’s the correct type for your Honda model and year. Aftermarket fobs can work just as well as OEM ones and are significantly cheaper.
- Autel MaxiAP200 OBD-II Scanner: This Bluetooth dongle plugs into your car’s OBD-II port and communicates with a smartphone app. It’s crucial to get the MaxiAP200 model, as other Autel scanners might have different licensing or functionality.
- A compatible smartphone (Android or iOS): You’ll need to install the Autel MaxiAP200 app on your phone to control the scanner and perform the reprogramming.
- Your Honda vehicle: Obviously, you’ll need the car you want to reprogram the key fob for!

Now, let’s get to the core of the process – reprogramming your Honda key fob. Follow these steps carefully:
1. Connect the MaxiAP200 and Launch the App
- Plug the Autel MaxiAP200 dongle into your Honda’s OBD-II port. This port is usually located under the dashboard on the driver’s side.

7. Follow the On-Screen Prompts
- From this point onwards, the MaxiAP200 app will guide you through a series of on-screen prompts to complete the key fob programming. These prompts are specific to your Honda model and may involve steps like:
- Pressing the start button with an existing working key fob inside the vehicle.

8. Test Your Newly Programmed Key Fob
- Once the app indicates successful programming, test your new key fob. Try locking and unlocking the doors, starting the engine (if it’s a push-to-start system), and using any other functions your key fob is supposed to control.
- If everything works correctly, congratulations! You’ve successfully reprogrammed your Honda key fob and saved yourself a potentially hefty service fee.
Important Considerations
- Push-to-Start Models: For Honda models with push-to-start buttons, ensure you are using the correct version of the Honda module with your MaxiAP200. Some older versions might require an external module or may not support push-to-start key programming. As of the latest updates, a beta Honda module V2.01.54, compatible with 64-bit Android phones, is needed for push-to-start models and might require requesting it from Autel directly.
- Follow Prompts Carefully: The on-screen prompts are crucial. Read them thoroughly and perform each step exactly as instructed for successful programming.
- Compatibility: While the Autel MaxiAP200 is widely compatible, always double-check the compatibility with your specific Honda model and year before purchasing and attempting to reprogram your key fob.

Reprogramming your Honda key fob at home is entirely possible with the right tools and guidance. By using an Autel MaxiAP200 OBD-II scanner and following these steps, you can potentially save yourself a significant amount of money compared to dealership or locksmith services. This DIY approach empowers you to take control of your car maintenance and address key fob issues efficiently and affordably. Always ensure you have the correct tools and compatible parts, and follow the instructions carefully for a successful outcome.
