- Single Cylinder: Key on outside, thumb turn inside (most common)
- Double Cylinder: Key required on both sides for extra security

Look for locks made from solid brass, steel, or zinc alloy for maximum resistance against drilling or prying.
3. Security Rating
Check for ANSI/BHMA certification – Grade 1 offers the highest protection for residential and commercial use.
4. Extra Security Features
Anti-pick pins, bump resistance, and reinforced screws all add crucial layers of protection.
5. Design & Finish
Choose a design that complements your door’s style – matte black, satin nickel, or brass finishes are the most popular for 2025.
Pro Tip: Combine a deadbolt with a reinforcement plate or door barricade (like the AceMining lock above) for unbeatable home defense.
