Narrative:
I was returning to my home field after a series of practice approaches. I loaded and activated the ILS 13R into the garmin 430 GPS and selected vloc; but forgot to swap frequencies. When the approach is activated; the garmin automatically loads the localizer frequency into the standby frequency; but it's necessary for the pilot to flip it to active manually. I intercepted the localizer and turned to the airport; mentally congratulating myself on nailing the approach so well that the needles seemed nailed - until approach called with a low altitude alert saying I was 1000 ft low. This was a loss of positional awareness as well as an altitude deviation. I should have cross-checked the GPS against VOR #2; and especially should have been suspicious that the GPS never deviated from center. Most of all; I should have flipped the frequency as soon as I selected vloc; and will add this to my approach checklist for future flights.
