I was working on adding a deadbolt to an exterior door. I started doing a lot of fine measurements to drill it out because I didn't want to crack the glass which was kind of close to the edge of the door.
Which I then questioned what the hell am I doing adding a deadbolt to a door with a massive window. If someone wants to get in, they're gonna get in. The only thing that really keeps my family safe is the fact the vast majority of my neighbors don't want to hurt me, not some lock on my door.
Actually it is probably easier to punch through the walls bypassing the door completely as opposed to breaking the glass. Though glass does break and so that is what someone will try.
The vast majority of my exterior is brick, but the area in question is just vinyl siding so you're not entirely wrong. A few more layers to get through: the vinyl siding, foam backing on the vinyl, vapor barrier, old cellulose insulation, then interior wall.
Just further shows the futility of putting an expensive lock on a regular home door. If someone wants in, they'll get in. The lock is definitely more of a "please don't come in" than anything real.
