1. A real deadbolt on every outside door
A knob lock alone can be slipped. A deadbolt with a full one-inch throw cannot. Use it every time, not just at night.
2. Long screws in the strike plate
The strike plate is the metal piece on the frame. Most come with short screws that only reach the trim. Three-inch screws reach the framing behind it, and that is often the difference when a door is kicked.
3. Sliding doors
Add a bar or pin so the door cannot be lifted or slid, and check that the latch actually catches.
4. Light and sight lines
A lit entry and trimmed shrubs by the doors take away places to work unseen.
5. Know where your keys are
Rekey after moving in, after losing a key, or when someone with a key moves out. A keypad lock means you can change the code instead of collecting keys back.
For more ideas, the FEMA building science pages cover doors in storms, which matters here in Brevard.
