YABADABADOU... I found it, thank you Slow Moving.
I had seen the key but never imagine IT WAS the key. There was a round empty space just next to it so I though is was holding the tool and it was missing.
For DanielFlading: DEF means Diesel Exhaust Fluid and $150 for service is very exact, I paid $172 last monday. $52 for the fluid and $99 for labour !
For Realebill: You were right, the key was provided, I was just too blind to see it !
Thank you all, I really like this forum.
Leaving October 20 for Florida !
