Suzy, you should not have to remove the window. When I did mine all I did was remove the inside frame. With the door open and standing on a ladder I was able to get at the receiver do what needed to be done. I did however have to rig up a couple of jumpers for the two contacts on the door and jamb.I just received a new keypad. Do I in fact have to take the window out of the door to reprogram the receiver? Thought I'd ask before I start taking things apart.
Thanks,
Suzy
