Choosing door hardware can be confusing, especially when terms like entry door knob, keyed entry knob, and front door lockset are used interchangeably.
So what exactly is an entry door knob?
In simple terms, an entry door knob is a locking door knob designed for exterior doors. It allows access from the outside using a key while providing secure locking for the home.
In this guide, we'll explain how entry door knobs work, where they are used, and how they compare to other common door knob functions.
What Is an Entry Door Knob?
An entry door knob is a lockable knob that includes:
✔ Exterior key cylinder
✔ Interior thumb turn or push-button lock
✔ Spring-loaded latch
Unlike passage or dummy knobs, an entry door knob is intended to control access to a home or building.
Most commonly, they are installed on:
- Front doors
- Side entry doors
- Garage entry doors
- Back exterior doors
How Does an Entry Door Knob Work?
A keyed entry knob operates using two primary components:
Exterior Side
Requires a key to unlock the door.
Interior Side
Typically uses:
- Thumb turn
- Push-button lock
- Interior locking mechanism
This allows homeowners to secure the door while maintaining convenient operation from inside.
Entry Door Knob vs Passage Door Knob
| Feature | Entry Knob | Passage Knob |
|---|---|---|
| Key Lock | ✔ | ✖ |
| Exterior Use | ✔ | ✖ |
| Security | ✔ | ✖ |
| Hallways | ✖ | ✔ |
| Closets | ✖ | ✔ |
Passage knobs are designed only to open and close a door.
Entry knobs provide controlled access and security.
Entry Door Knob vs Privacy Door Knob
Privacy knobs are commonly used on:
- Bathrooms
- Bedrooms
- Home offices
Unlike entry knobs, privacy knobs:
✖ Do not use keys
✖ Are not intended for exterior security
✔ Provide temporary privacy only
What Is a Keyed Entry Door Knob?
Many homeowners use the terms interchangeably.
In most cases:
Entry Door Knob = Keyed Entry Door Knob
The phrase simply emphasizes that the knob includes a key-operated lock cylinder.
Do You Need a Deadbolt With an Entry Door Knob?
While an entry door knob provides security, most front doors also include a deadbolt.
Benefits of adding a deadbolt:
✔ Higher resistance to forced entry
✔ Better front door protection
✔ Improved home security
✔ Meets modern security standards
For this reason, many homeowners choose:
- Entry Knob + Deadbolt
- Entry Lever + Deadbolt
- Handleset + Deadbolt

Final Thoughts
An entry door knob is a keyed locking knob designed for exterior doors and controlled access. It differs from passage, privacy, and dummy knobs because it provides actual security rather than simple operation or privacy.
For most homes, pairing a quality entry door knob with a deadbolt offers the ideal balance of convenience, durability, and front door security.
