Crowbars are a standard aspect of any breechkit, and can be defeated for under $10.
You can increase your bolt to more than 1 inch, and reinforce your door framing with a steel plate, or add a unlocking plate to the base of the door.
Anything you can do, including lobbing (yes Faust, lobbing is a word) a tank shell at a random point in the wall, a suggestion some military manuals offer, can be countered in advanced.
Better, but you still wouldn’t get through a aluminum, styrofoam reinforced door with a $30 floor jam easily.
You can get in though with other kits though.
And in the attempt, as well as once in, alarms of different sorts, or more traditional security suchs as dogs, people with guns… it can be a nightmare looking for a safe, some are hidden, others are designed to withstand 30+ attacks on them.
It is why most crime occurs in the slums, the poor raping the poor, rich can readily afford a range of upgrades that will significantly confound and confuse any criminal.
However, this doesn’t mean the poor are helpless, any number of techniques and very cheap to free upgrades can be made to improve your security standings.
If your minded to start a criminal enterprise, and can calculate all the methods needed to overcome these issues, then I recommend instead you just get into the locksmith and home security business itself and get paid to counter it… you will have a legally recognized business, and you will get invited and paid to people’s home and businesses to install devices, and you can try to upsell them on select devices. Government will only seek after you for due diligence lapses (not checking for ID) or tax evasion, not for your work. Hell, the police may even hire you out on occasion for Sneek and Peek Warrants, or call you up after a domestic violence case to upgrade or rekey a premise…
