Hi guys,
I am having a problem with my Fob, it's not being able to open the passenger door. I have seen some similar threads pointing to the actuator, but what is interesting in this case is that I was able to lock and unlock both doors from the inside with the driver's side lock switch. After I programmed the fob, though, the lock switch also just locks the driver's door.
Meanwhile I am having to unlock manually the passenger's door when I go inside the car, because even after "unprogramming" the fob, the lock switch won't work on both doors anymore.
The Fob I have is this generic one from amazon: Please help me out if you can. Thank you in advance!!
