The storm knocks the power out mid-afternoon, the way it does more than once during a Florida storm season, and you're standing in the garage staring at a door that won't budge. Maybe your car is already outside and you need to get it in before the next band of rain hits. Maybe you're headed to work and the door is sealed shut with the opener dead. Either way, every garage door with an automatic opener has a manual release built in for exactly this moment, and knowing how to use it safely can save you a service call and a soaked car.
