I have a craftsman 1/2 hp garage door opener. I bought a new keypad that mounts on the outside of the garage a year ago. Lately when using the key pad it doesn't always work and my wireless in my car doesn't always work. I changed both batteries 9V and it still isn't working right. Do I need to reset it. thanks
