Keypad Out of Range

More than once we've had the keypad out of range error. Nothing works except to reset by removing the batteries. For the 5th or 6th time now, I've just had to add all my sensors and devices again. Super frustrating, and tech support only provided the naming on my behalf as I went to each device to push the button, one at a time. Had anyone else experienced this? Any suggestions on how to prevent this from happening?
