Frequently asked questions
How is the grade calculated?
You start at 100, and each weak point deducts points based on how much it matters, from a single front-door lock to unlocked windows or unaccounted-for keys. The final score maps to a grade from A to E, and the three biggest deductions become your ranked fixes.
What does a deadlock add to my score?
A quality deadlock on your front door removes the single-lock penalty, and a high-security deadlock adds a small bonus. Deadlocks resist forcing far better than a basic latch, which is why they carry weight in the grade.
Should I rekey after moving in?
Yes, and the grader deducts points if you have not, because you cannot know how many old keys are still out there with previous owners, agents or tradespeople. Rekeying is a fast, affordable way to guarantee only your keys work.
