Turning the valve off and on is not something they may like, but you should do it once or twice a year anyway. If you try and cannot move it, call them and have it fixed. Then you can keep it free or know when to call them if it is not. You should know where and how to shut off gas, water and electricity. You may choose not to shut off electricity on a regular basis if, like my area, the only way to do it is to remove the meter. If that is your only option you should know how to do it. I have needed to do it several times when I was working in the service panel. I know I should install a master shut off but I keep putting it off till I replace the panel, which I need to do.
