I have a french door opening up to the back porch. Only one door opens, as the other is fixed in place.
I am looking for extra security measures to lock up the back door while gone for the day, while not damaging or drilling holes in the metal door.
Are there any devices like security cables that lock around the two door knobs, etc. that aren't a pain in the ass to deal with when you want to unlock/remove it?
Thanks in advance, GD!
