use only alkaline batteries............ BRAND NEW

regular carbon zinc cant meet the demands

check the antenna on the opener likely a small wire haning out in space
from the opener

any chance you recently added a fluroscent lamp, espically the compact
type? they can interfer with openers......

Or cold weather drifted the receiver frequency if it is not PLL
