My HarleyDavidson Topper's key code has been a nightmare. Trying this now.

I have a 2011 HarleyDavidson Topper, will this method work for that year?

I’m also looking for how to retrieve the key code on a HarleyDavidson Topper.

Key Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
