Was the wire accessible from the exterior?

Usually there is a key cylinder that can be removed from the outside when the door is down. It is typically on garages that do not have access from the house or an exterior door. If the power goes out you can gain access.

If you looked at the exterior of the door, you would see a keyed lock. After turning the key, the lock can be pulled out of the door. Give it a tug and it will release the trolley from the drive chain and you can manually open the door.

...Thanks for the help!

This door from Wednesday will only open if you push in at the top with one hand while lifting with the other.

The lock and cable are for when there is a power outage and you are on the outside of the garage.

Around here the are called a vault lock. I have one myself as I do not have a secondary access to my garage. They do come in handy during a power outage.

John - isn't that top track too short? Shouldn't the wheel always be inside the track even when the door is closed?

That's probably why you have to "push in with one hand while you lift with the other".

That's a standard two track low head room setup. The top track isn't too short, the roller is in the wrong bracket.
