For owners of a 2007 Harley Davidson motorcycle, the key fob security system, while intended to protect your prized possession, can sometimes become a source of frustration. Whether it’s a dead fob battery at an inconvenient time or simply a desire for a more straightforward ignition process, disabling the factory-installed Hands-Free Security Module (HFSM) is a viable option. This guide provides a step-by-step process to bypass your 2007 Harley Key Fob security system, allowing you to start your bike without the need for the fob.
This procedure involves replacing the HFSM with a standard Turn Signal Module (TSM) and performing a series of ignition steps to recode the system. By doing so, you effectively remove the key fob dependency, simplifying your starting procedure. Please note that while this process disables the key fob security feature, it’s crucial to consider alternative security measures to protect your motorcycle from theft.
Here’s how to disable the security system on your 2007 Harley Davidson:
Step-by-Step Guide to Disable the 2007 Harley Key Fob System
Before you begin, ensure you have a 2 amp battery charger ready. This procedure requires the bike’s ignition to be on for an extended period, and maintaining battery voltage is essential to prevent interruptions.
-
Preparation: Ensure the ignition has been turned OFF for at least 15 seconds before starting this procedure. This ensures the system is in a proper starting state.
-
Engage Run Switch: Set the Run/Off switch on your Harley Davidson to the RUN position.
-
Ignition ON (No Start): Turn the ignition key to the ON position, but do not attempt to start the engine. Observe the instrument panel: the Check Engine Light and Security Light should illuminate. Wait for both of these lights to turn off. This indicates the system is ready to proceed.
-
Attempt to Start: Press the Start button as you would for a normal engine start. The engine should briefly start and then stall. The Check Engine Light will illuminate and remain on. This is expected and part of the process.
-
Ten-Minute Wait (First Cycle): Wait for ten seconds after the engine stalls. The Security Light will now turn on. This signifies that the Engine Control Module (ECM) has entered communication mode with the TSM. Set a timer for ten minutes and allow the system to communicate. During this period, do not turn off the bike, allow the battery to die, flip any switches, or disconnect any electrical components. You can use this time for routine bike maintenance like polishing.
-
Ignition Off-On (First Cycle): After ten minutes, the Security Light will turn off. Within 15 seconds of the Security Light turning off, quickly turn the ignition key OFF and then back ON. This Off-On action should be swift, completed in two seconds or less. The Security Light will illuminate again, initiating another ten-minute communication cycle.
-
Ten-Minute Wait (Second Cycle): Wait for another ten minutes while the Security Light is illuminated. As before, maintain the bike’s state and battery charge.
-
Ignition Off-On (Second Cycle): Once the Security Light turns off for the second time, repeat step six. Perform the Off-On ignition key motion within 15 seconds of the light extinguishing. The Security Light will come back on, initiating a third and final communication cycle.
-
Final Ignition OFF: When the Security Light turns off for the third time, perform the Off-On ignition sequence one last time. This time, when the Security Light illuminates again, turn the ignition key to the OFF position. Wait for at least 15 seconds. During this pause, carefully disconnect your battery charger, unplugging it from the wall outlet first, then from your motorcycle.
-
Final Start: After waiting for at least 15 seconds, turn your ignition ON, ensure the Run button is engaged, confirm the bike is in neutral, and start your Harley Davidson.
Congratulations! You have now successfully disabled the key fob security system on your 2007 Harley Davidson. The ECM and the new TSM are now communicating without the need for the HFSM.
Important Considerations
By completing these steps, your 2007 Harley Davidson will start without requiring the key fob. Remember to store your key fob, the original HFSM, and a printed copy of these instructions together in a safe place. This will be beneficial if you decide to revert to the original security system in the future, especially when selling your motorcycle.
While this modification simplifies starting your bike, it also removes a layer of security. Consider using a fork lock or other aftermarket security measures to protect your motorcycle from theft, particularly when parked in public areas. Enjoy the convenience of key fob-free riding, and always prioritize the security of your motorcycle.
