coding black key
I purchased a low mileage repo'd 06 620 with only the red key. Bought a owners manual for a 620/620dark off epay but I can't find anything explaining how to code a black key from the red. I only have 1 cut black key but the tech from the Duc shop that sold me the key (only had 1) said I could add a black key and that only one would be required. I have tried various red key on, black key on, red key on scenerios from 1 sec on to yellow light on to gauge movement on but when I try my black key again it ends with 2 fairly long blinks and then a solid yellow. What am I doing wrong? thanks
