Not all levers are created equal. They are built for different purposes, from providing light privacy to securing your home’s perimeter. Here’s a simple breakdown of the four main functions you’ll encounter.
1. Privacy Levers (Push-Button or Turn-Button)
This is the most common type of locking lever on interior doors, like those for bedrooms and bathrooms.
- How it Works: You lock it from the inside by pressing a central push-button or twisting a small thumbturn. The magic is in the auto-release: turning the interior lever to exit will automatically disengage the lock. This is a safety feature to prevent you from accidentally locking yourself inside a room. Understanding how do push button locks work reveals why this feature is central to their design.
- Key Feature: Designed for privacy, not high security. They are not meant to be locked from the outside after you leave.
2. Keyed Entry Levers
These are your frontline security for exterior doors like your front door, back door, or garage entry.
- How it Works: They feature a key cylinder on the exterior and a thumbturn on the interior. This is the only type of lever lock designed to be securely locked and unlocked from the outside with a key. It offers robust security, giving you control over how to lock a door from both sides.
- Key Feature: When deciding on your home’s security, it’s helpful to understand the difference between keyless entry and key entry systems to find what best suits your needs.
3. Storeroom Levers
You’ll often find these on commercial doors, such as supply closets or public restrooms.
- How it Works: The outside lever is always locked. You need a key to open it from the outside every single time. The inside lever, however, is always unlocked, allowing for a quick and safe exit.
- Key Feature: The door automatically locks when it closes. There is no way to leave it unlocked from the exterior.
4. Passage Levers
The simplest of them all, passage levers are used for doors that don’t require locking, like hall closets or laundry rooms.
How it Works: They have a latch to keep the door closed but no locking mechanism at all.
Key Feature: They turn freely from both sides and cannot be locked.
