How often do you have to reprogram them. A friend of mine takes care of it for me, but them seem to get "zapped" on a regular basis. Talked to another guy who would do it for the sum of $400/year and guaranteed they would not get "zapped", but if they did, he would fix it. Didn't take advantage of that offer. Don't watch enough TV for that kind of cake. Just wondering how often you have to do it.
