Deadbolt grades explained: what makes a door lock secure
A good lock on a weak door still fails. Here is what actually makes an entry door secure.
Lock grades
- Residential locks are often rated Grade 1, 2 or 3, with Grade 1 the strongest.
- A higher grade usually means heavier parts and better resistance to force.
- Look for the grade on the packaging or the product sheet.
The door and frame matter
- A solid or reinforced door resists kicking better than a hollow one.
- Most kick-ins fail at the frame and strike plate, not the lock.
- Long screws that reach the framing make a big difference.
Other upgrades
- High-security cylinders resist picking and bumping.
- A deadbolt with a one inch throw is a good minimum.
- Door reinforcement kits strengthen the area around the lock.
