What does high-security locks involve?
High-security locks resist picking, bumping, and drilling better than standard locks, and their keys are restricted: they cannot be copied at a hardware counter without authorization.
They are worth it on doors where key control matters: a home with many past keyholders, a rental with frequent turnover, or a business office, server room, or stock room.
What's included
- Medeco and Mul-T-Lock cylinders
