Good call. Congrats on the buy and welcome to the mazda 6, aka mazda pimpdaddy whip, forum! I agree on the locks, wicked slick feature. Even more fun is playing with the windows using the button and the remote, IMO!
i'm gonna have to research the window feature. as of now the only window that will roll down is the drivers side, but after searching the forums it looks like i just need to reset them.
