The emergency release lock typically sits flush with your garage door, as it’s meant to blend in. It will almost always be dead-center and near the top of your garage door. If you don’t have your key, you can still open your garage door from the inside. However, you do need your emergency release key to open your garage door from the outside.
You can either pull the key out now and store it for safe-keeping, or you can leave it in the manual lock to use once you’re safely inside the garage.
Make sure you push the garage door all the way open. If you only open it halfway, it could fall back down again.
Even though the power is out now, it could come back on later. Unplugging the door opener saves you from damaging the assembly and having to do a tough re-installation later on.
If you’re pulling super hard and don’t hear a click sound, the garage door might not be closed all the way. Pull the door down manually until it touches the floor, then try pulling the cord again.
Make sure you open the door all the way. Opening it halfway could make the door fall back down, which can be dangerous.
If you plan on leaving, use your emergency release key to lock the manual lock on your garage door.
You can also pull the cord vertically to disengage it, although this is slightly harder to do.
It can take about 30 seconds for the garage door opener to reboot itself. Try opening and closing your garage door a few times to double check that the door opener is powered on.
