554t no response from transmitter

Hi, everyone. What's going on? Here is my problem. I have the hornet 554t and last 3 weeks all of my transmitter was not repsonding. Even opening the door and trying to disarm it using the valet switch and the key was not working. The alarm don't work until i disconnect the battery for about 30 seconds, then reconnect. Every thing works after that. Yesterday the same problem occur . It seems that the alarm needs reseting for it to work. What causes that? I checked all connection and that are all tight- no loose connection.        Also i have the DEI window roll up. they have the one touch control for up and down. When it was recently installed they work perfect. Now they stop midway a few time going up or down. Usually at the same spot and you have to activate the window switch again for it to continue moving. What i did is open the window module box and resolder all the connections and then it would work perfect. This usually happens every two months .Any suggestion to solve this ..Thanks guys and gals .... "I'm So Loud It Hertz"
