Harley Davidson motorcycles are renowned for their iconic design and robust security systems. A key component of modern Harley security is the proximity key fob. This convenient device allows for keyless operation, starting and disarming the security system as long as it’s near the motorcycle. However, losing a key fob can be a significant inconvenience. Fortunately, with the right tools and knowledge, programming a new key fob for your Harley Davidson is a straightforward process. This guide will walk you through programming a Harley Davidson key fob, ensuring you can get back on the road with minimal hassle.
Understanding Harley Davidson Key Fobs and Security Systems
Modern Harley Davidson motorcycles often come equipped with a sophisticated security system that integrates with a proximity-based key fob. This system enhances security by automatically arming itself when the fob is no longer in close proximity to the bike, and disarming when it detects the fob nearby. This proximity feature offers a seamless user experience – no need to fumble for keys or press buttons to start your ride.
The key fob itself communicates wirelessly with the motorcycle’s Body Control Module (BCM). When a valid fob is detected, the BCM authorizes the engine to start and allows normal operation. If an unprogrammed or unrecognized fob is present, or no fob is detected, the security system will prevent the motorcycle from starting, effectively deterring theft.
Losing a key fob can render your motorcycle unusable, as a new, unprogrammed fob will not be recognized by the bike’s security system. Attempting to start the motorcycle with an unprogrammed fob will result in no response – the lights won’t illuminate, and the engine won’t turn over. This is where the programming process becomes essential. Luckily, with tools like a Snap-on scan tool and the correct procedure, you can easily program a new fob and regain full use of your Harley Davidson.
Step-by-Step Guide to Programming Your Harley Davidson Key Fob
Programming a Harley Davidson key fob, especially with tools like a Snap-on scan tool, is a relatively simple procedure. Here’s a detailed step-by-step guide to help you through the process:
Accessing the Body Control Module (BCM)
The first step is to access the motorcycle’s computer system using a diagnostic scan tool. For Harley Davidson models, a Snap-on scan tool with software version 17.2 or newer is recommended.
- Connect the Scan Tool: Plug your Snap-on scan tool into the diagnostic port on your Harley Davidson. This port is typically located in an easily accessible area, often under the seat or side panel.
- Navigate to Harley Davidson Diagnostics: Power on the scan tool and navigate to the Harley Davidson diagnostic menu.
- Select Body Control Module (BCM): Once in the Harley Davidson menu, locate and select the “Body Control Module” or “BCM” option. The scan tool may automatically determine the specific BCM your motorcycle is equipped with.
Navigating to Key Fob Programming Function
Once you’ve accessed the BCM, you need to find the key fob programming function within the scan tool’s menu.
- Enter Functional Tests: Within the BCM menu, look for “Functional Tests”. This section contains various diagnostic and configuration options.
- Find Special Functions: In the “Functional Tests” menu, locate and select “Special Functions” or a similar option.
- Select Configurations: Within “Special Functions,” you should find “Configurations.” This is where key fob programming and other configuration settings are typically located.
Entering the 24-Digit Key Fob Code
This is the crucial step where you input the unique code associated with your new key fob.
- Locate Key Fob Code: Your new Harley Davidson key fob should come with a 24-digit code. This code is usually found on a tag or card included with the fob packaging. Ensure you have this number readily available.
- Edit Key Fob Setting: Within the “Configurations” menu on your scan tool, find the key fob programming parameter. It might be labeled as “Key Fob ID,” “Fob Programming,” or similar. Select the “Edit” option for this parameter.
- Enter the 24-Digit Code: Carefully enter the 24-digit code from your new key fob into the scan tool. The scan tool interface will typically provide a numerical keypad for input. Double-check the code for accuracy before proceeding.
- Confirm and Program: Once you’ve entered the code, select “OK” or “Confirm” on the scan tool. The scan tool will then program the new key fob code into the BCM. You may be prompted to confirm the code again for verification.
Verifying the Programming
After programming the key fob, it’s essential to verify that the process was successful.
- Cycle the Ignition: Turn off the motorcycle’s ignition, then turn it back on.
- Check for Power: Observe the motorcycle’s instrument panel. With a successfully programmed key fob, the lights should come on, indicating that the system is recognizing the fob.
- Start the Motorcycle: Attempt to start the motorcycle. If the programming was successful, the engine should start without any issues.
If the motorcycle powers on and starts, congratulations! You have successfully programmed your new Harley Davidson key fob.
What to Do if You Lose All Key Fobs
In situations where all key fobs are lost, Harley Davidson provides a backup solution using a Personal Identification Number (PIN). This PIN is pre-programmed into the BCM and can be used to disarm the security system and start the motorcycle in the absence of a key fob. The procedure to use the PIN typically involves using the turn signals in a specific sequence, as detailed in your Harley Davidson owner’s manual. While this allows for emergency operation, programming a new key fob is still recommended for convenient, everyday use and security.
Conclusion
Programming a Harley Davidson key fob is a manageable task, especially with the aid of a diagnostic scan tool like a Snap-on. By following these steps, you can quickly program a new fob and ensure your motorcycle remains secure and operational. This ability is not only convenient for individual owners but also crucial for automotive technicians and service centers that assist Harley Davidson riders. Having the knowledge and tools to program key fobs efficiently ensures customer satisfaction and keeps these iconic bikes running smoothly.
