I just ordered a new remote for a 93 740iL, the guy at the dealership told me that i would have to change the chips in both remotes and in the car. He told me that there was a box on the passenger's side. He told me to take out the glovebox and it shoul be somewhere back there. I changed the chips in the remotes and then i went into the car and i found a box but it wouldn't open, it was right above the glove box. Was it the right box and if it was how do i get it open, if not, then where is the right box.
