How to Program a Harley Davidson Key Fob: Your Step-by-Step Guide

Ensuring your Harley-Davidson’s security system is functioning correctly is paramount for peace of mind. A key component of this system is your key fob. Whether you’re facing issues with an unresponsive fob or simply need to program a new one, understanding the process is essential. This guide provides comprehensive instructions on how to program your Harley Davidson key fob, covering both the Turn Signal Security Module (TSSM) and the Hands-Free Security Module (HFSM) systems.

Programming a Harley Davidson TSSM Key Fob

The Turn Signal Security Module (TSSM) key fob, easily identified by its rubber button, requires a specific procedure to reset its code. Follow these steps carefully to reprogram your TSSM key fob:

1. Ensure the Kill Switch is Off: Begin by setting your Harley-Davidson’s kill switch to the “off” position. This is a crucial safety step before initiating any programming sequence.

2. Ignition Switch Cycling: Rapidly turn the ignition switch “on” and “off” a total of three times, ending with the ignition in the “on” position. This rapid cycling is key to entering the programming mode. The sequence is: On, Off, On, Off, On (5 actions in total).

3. Engage the Left Turn Signal: Immediately after the ignition cycling, quickly press and release the left turn signal switch twice. This action further navigates the system into the programming sequence.

4. Press and Release the Fob Button: Firmly press and release the rubber button on your TSSM key fob once. This signals to the system that you are initiating the programming process.

5. Observe the Odometer for the Current PIN: After performing the previous steps, your Harley-Davidson’s odometer should display the current 5-digit PIN code. This confirms you’ve successfully entered the programming mode.

6. Modify the PIN Code (Optional): If you wish to change the PIN code, use the left turn signal switch to increment the first digit to your desired number. Each press of the left signal switch will increase the digit.

7. Proceed to the Next Digit: Once the first digit is set, press the fob button twice. This action cycles the display to the next digit of the PIN code, allowing you to program each digit sequentially. Repeat step 6 and 7 until all five digits reflect your desired new PIN.

8. Finalize the Programming: After setting all five digits of your new PIN, press and release the right turn signal switch once, and then turn the ignition switch to the “off” position. This completes the programming sequence and saves your new PIN.

(Remember to perform steps 2 to 4 quickly and consecutively for successful entry into programming mode.)

Arming and Disarming Your TSSM Security System

To arm and disarm your Harley-Davidson’s security system using the TSSM with your programmed PIN (let’s use a sample PIN of 25522 for this example):

1. Ignition to Accessory: Turn your ignition switch to the “Accessory” position.

2. Simultaneous Turn Signal Activation: Press and hold both the left and right turn signal switches simultaneously. You should observe the red key light on your speedometer flashing rapidly. This visual cue confirms you’ve correctly initiated the arming/disarming sequence.

3. Enter the PIN Code: Now, input your 5-digit PIN code using the turn signals. For our example PIN 25522, the sequence would be:

   • Press and release the left turn signal twice (for the first digit ‘2’).
   • Press and release the right turn signal once (to move to the next digit).
   • Press and release the left turn signal five times (for the second digit ‘5’).
   • Press and release the right turn signal once.
   • Press and release the left turn signal five times (for the third digit ‘5’).
   • Press and release the right turn signal once.
   • Press and release the left turn signal twice (for the fourth digit ‘2’).
   • Press and release the right turn signal once.
   • Press and release the left turn signal twice (for the fifth digit ‘2’).
   • Press and release the right turn signal once.

4. Security System Status: If you have successfully entered the correct PIN, the rapid flashing of the red key light on the speedometer will cease. This indicates that the security system is now disarmed.

(Ensure steps 2 to 7 are performed swiftly and without pauses for successful arming or disarming.)

Programming a Harley Davidson HFSM Key Fob

For Harley-Davidson models equipped with the Hands-Free Security Module (HFSM), characterized by a solid plastic key fob, the programming steps are slightly different:

1. Key Fob Presence: Ensure your HFSM key fob is physically present with you and near your motorcycle.

2. Kill Switch to Off: Set the kill switch to the “off” position.

3. Rapid Ignition Cycling (HFSM): Quickly turn the ignition switch “on” and “off” three times, ending in the “on” position, just like with the TSSM system.

4. Left Turn Signal Activation (HFSM): Immediately after ignition cycling, press and release the left turn signal switch twice.

5. Right Turn Signal Activation (HFSM): Follow this immediately by pressing and releasing the right turn signal switch only once.

6. Odometer PIN Display (HFSM): The current PIN code should now be visible on your motorcycle’s odometer.

7. PIN Modification (HFSM): To change the PIN, use the left turn signal switch to adjust the digit upwards.

8. Digit Progression (HFSM): Press the right turn signal switch to move to the next digit in the PIN sequence. Repeat steps 7 and 8 until your desired 5-digit PIN is programmed.

9. Complete Programming (HFSM): Once you’ve entered your new 5-digit PIN, switch the ignition to the “off” position to save the changes.

(Steps 3 to 5 for HFSM programming need to be executed quickly and without delay.)

Arming and Disarming Your HFSM Security System

Arming and disarming the HFSM security system follows the same procedure as the TSSM system, but with one key difference: start by turning the ignition switch to the “on” position instead of “accessory” in step 1 of the TSSM arming/disarming process. Then proceed with steps 2-4 of the TSSM arming/disarming instructions, substituting your HFSM key fob and PIN.

Still Having Trouble? Contact a Harley-Davidson Dealership

While these steps provide a comprehensive guide on how to program your Harley Davidson key fob, complexities can arise. If you encounter difficulties or prefer professional assistance, do not hesitate to contact your local authorized Harley-Davidson dealership. Dealerships possess specialized software and hardware to accurately assign Harley-Davidson PIN codes and program new key fobs efficiently.

For expert assistance with key fob programming, obtaining a new PIN, replacing your key fob battery, or any other security system concerns, a Harley-Davidson dealership is your best resource. They can ensure your security system is properly configured, giving you confidence and security every time you ride.
