No power going to the electric door, passenger window and power locks and A/C do not work while alarm is engaged

My car listed above is the LX-P model. The alarm is engaged on my vehicle. I cannot get the alarm to be disengaged by the key fob. It seems that the key fob will not work because there is no power going to the door with the power windows to make a connection. Because of this the A/C is also not cooling. The problem occurred initially and the key fob was working sometimes (in and out) but once the alarm was disengaged, the A/C started cooling again and the power windows worked. Now it seems to be fully gone as there is absolutely no power going to the power door. The rear windows work but the passenger window and power locks and A/C do not once the alarm is still engaged. I cannot disengage the alarm any other way. Please assist.
