If it is the Honda factory alarm, it can be changed from the auto slarm
setting. There are three positions for the switch. It was supposed to be
set on manual at the factory. Anyway, you have to find the main alarm unit
under the dash, and set the arming mode switch to manual. This means the
alarm only arms when you lock the doors with the key fob. At least the
neighbors will appreciate it. You should have received a book on the
security system along with the owners manual if you bought it new.
