I am really having trouble finding someone to help me with this for a reasonable price ~$75. Anyone have any ideas?

It may be far from you, but Parker Davis @ Broad Stroke Associates (Snohomish) has done reprogramming for me and he's awesome. At a minimum, give him a call.

Signature in Kirkland did my LCM reflash a few months back for $40. Best price I could find before them was 1hr labor

hey just a quick question. what year is your m3?

i notice you have led tail lights but DO NOT have the longer trunk handle.

the lcm may not be reprogrammable if you didnt switch it out depending on year and build date.
