Mercedes Key Fob question.

Asked by Jun 29, 2017 at 09:46 PM about the 2009 Mercedes-Benz SL-Class SL 550

Question type: General

After losing my last key, I went to Mercedes and got a new
one. However when I got the new key all the buttons
work, except now the key can never be detected by my
car when I try to open the door without clicking buttons or
clicking the push to start. Do any of you guys know how
to make the car "detect my key" wirelessly? THANKS!
