20 Tricks a Retired Locksmith Teaches Seniors Living Alone That Burglars Hate

A burglar can defeat an expensive alarm simply by getting through the door before anyone can react. This video breaks down twenty practical security fixes a retired locksmith learned from decades of working on real homes—especially houses where seniors live alone. From removing address tags from key rings and securing windows, garage releases, sliding doors, spare keys, and unknown key copies to adding better deadbolts, door braces, reinforced strikes, and stronger jambs, most of the weaknesses are surprisingly simple. The biggest lesson is also one of the cheapest. Many doors fail because the strike plate is held only by tiny screws buried in soft wood. Replacing them with three-inch screws that reach the wall framing can dramatically strengthen the entire doorway. Good security starts before the alarm ever sounds.
