Weird remote start problem based on the car's location!

I have a 96 Nissan Maxima with remote start. The remote start will work 90% of the time which is great. But it doesn’t work in my driveway or on the street in front of my house! Even if I stand right in front of the car or change the angles. I can be two blocks away when the car is in another area and it works fine. I imagine there is some weird interference, but what could that be? I use the remote locks and they work fine. Any thoughts?
