To program a buttonless key fob for a Harley Davidson motorcycle, follow these steps:

Turn the ignition switch to the "off" position
Press and hold the left-hand control switch and the turn signal switch simultaneously until the turn signals flash (approx. 7 seconds)
Release both switches
Turn the ignition switch to the "on" position
Repeat the process for additional key fobs if desired
Turn the ignition switch to the "off" position to exit the programming mode.

Note: This procedure may vary depending on the model and year of the motorcycle, so refer to the owner's manual or visit https://bikerwhizz.com/how-to-program-a-harley-davidson-buttonless-key-fob/ for specific instructions.
