prestige 997 channel

I have a 2007 Mustang with the Prestige 997. I am adding a window module (DEI 530T) to roll up and down the windows. How can i access channel 5 and 6 on the lcd remote?

The remotes come pre-programmed only up to channel 4. You have to go into transmitter programming, and program the additional channels to the remote(s). You can use any unused button, or any button combination you want. I would say maybe you might choose Lock and Option together as "windows up," and Unlock and Option together as "windows down."
