what kind of safe did you have and how did they get into it?
Almost too embarrassed to admit some of the facts, but to serve as a lesson for others:
I did beef up the basement door with a deadbolt and reinforced lock strike plate, but over-estimated the door frame. Door was still properly locked when it was kicked off the hinges.
The "safe" was welded up by a machine shop in N Carolina. Heavy plate steel, two man job to move, ....but.... original plan to build a Greenleaf lock into the door fell through when the builder got sticker shock. I would up with a handle with a Master combo padlock on it. Plan b was to add a padlock cover over the lock to protect it from direct attack...but never got around to it.
End result is an unshielded mid grade combo padlock was picked. It probably would have been cut if it were more challenging. Thief did go through my work bench. Just dumb luck that my metal cutting blades weren't handy. A bolt cutter was in my toolbox if he looked harder.
In hindsight, the padlock was stupid. The extra $400 (20+ years ago)for the Greenleaf is a fraction of the theft loss. No excuse for not having at least a top end padlock with security cover. I made it too easy for him.
A legit safe is in the works. Alarm system too. House is unattended too many hours a day not to have one. Old "safe" now has an upgraded lock and will pull secondary duty for all the other items. Car and motorcycle keys, check book, camera, laptop, etc .... were all laying around and could have been gone just as easy.
