Deadbolt Types
Single-Cylinder, Double-Cylinder, and Upgrade Planning
The right deadbolt depends on the door, nearby glass, your daily use of the entry, and the level of security you want. We help homeowners compare common residential options and choose hardware that fits the door correctly rather than forcing a one-size-fits-all answer.
- Single-cylinder deadbolts with a key outside and thumb turn inside
- Double-cylinder deadbolts with a key on both sides for certain layouts
- Replacement deadbolts for worn or outdated hardware
- New installs when a door needs deadbolt protection added
- Compatibility planning for matching finishes, keys, and other front door hardware
