A door knob with no lock is a passage knob: it turns freely from either side, with no key or push-button lock to manage. That makes it a practical choice for hallways, closets, and other rooms where you want the door to latch closed but stay easy to open. The four options below are all passage-style knobs; compare pack size, finish, and door fit before choosing.

Probrico Round Passage Door Knob: A Single Knob for a Simple Swap
This single Probrico knob has a round shape and black finish, with a passage function that lets you open the door from either side. It has no locking mechanism, so it suits a hallway, closet, or another space where the door should not be secured for privacy.
The adjustable latch is designed for either a 2⅜-inch or 2¾-inch backset and doors 1⅜ to 1¾ inches thick. The listing specifies a square latch plate that cannot be removed, so check your existing latch opening and trim before ordering. Its stainless steel construction and straightforward design make it a practical replacement option when you only need one knob.
Compared with the multi-packs below, this is the simplest choice for a one-door project. The main limitation is the quantity: it is not the economical or convenient pick if you are changing several knobs at once. And while the listing mentions interior and exterior doors, a passage knob provides no security, so it should not be treated as a locking exterior entry set.
Pros:
- One-knob pack suits a small repair or replacement.
- Passage function stays openable from either side.
- Adjustable for two common backsets.
- Black stainless steel finish offers a simple, modern look.
Cons:
- The square latch plate is not removable.
- Provides no privacy or security lock.
Verdict: Choose this Probrico set if you need one black passage knob and have confirmed that its latch dimensions match your door.
Probrico Two-Pack: Matte Black Knobs for a Pair of Doors
This Probrico set includes two matte black passage knobs, making it a good fit when you want matching hardware on two doors. Like the single-knob option, it turns from either side and has no lock. It is intended for spaces such as hallways and closets where the door should remain accessible.
The adjustable latch fits 2⅜- or 2¾-inch backsets and doors 1⅜ to 1¾ inches thick. The listing also notes that its square latch plate cannot be removed. Confirm those measurements before buying, especially if you are replacing an older knob with a different latch shape.
The two-pack shares the single Probrico model’s black stainless steel construction and basic round-knob style. Its main advantage is having a matching pair in one package; if you need knobs for a larger project, the six-packs below may be a better fit. As with any passage knob, it is not appropriate where you need a privacy lock or secure entry.
Pros:
- Two matching knobs for a small multi-door update.
- Matte black finish works with contemporary hardware.
- Adjustable latch supports two common backsets.
- Freely operates from either side of the door.
Cons:
- The square latch plate is not removable.
- No locking function for bedrooms or bathrooms that need privacy.
Verdict: This two-pack is a sensible option for matching a pair of interior doors, provided the latch and door thickness match your setup.
AEEKEL Six-Pack: Matte Black Knobs for Coordinated Rooms
AEEKEL’s six-pack is designed for homeowners who want the same round, matte black look across several doors. These are passage knobs, so they remain operable from both sides without a key or locking button. That makes them suitable for closets, hallways, and other rooms where a door should close but not lock.
The listing describes stainless steel construction and an adjustable latch for 2⅜- or 2¾-inch backsets. It gives a door thickness range of 1.38 to 1.78 inches, which is slightly wider than the ranges listed for the other picks. The square latch plate is not removable, so measure your door and check the latch style rather than relying on appearance alone.
Each knob is listed as individually packaged with installation accessories and instructions, and the knobs are reversible for left- or right-hand doors. The six-piece quantity is useful for a larger project, but may be more than you need if you are replacing just one or two knobs. This is also not a substitute for a privacy or entry lock.
Pros:
- Six matching knobs can coordinate a multi-door update.
- Matte black round design is easy to pair with similar hardware.
- Reversible design suits left- or right-hand doors.
- Adjustable latch supports two common backsets.
Cons:
- The square latch plate is not removable.
- The six-pack may be excessive for a small replacement job.
Verdict: Pick the AEEKEL set if you want six matching matte black passage knobs and your doors fall within its stated measurements.
Sopoby Six-Pack: Black Passage Knobs with a Contemporary Look
This six-pack of black round knobs is another option for updating several interior doors at once. Its passage function means the knob operates from either side without a locking mechanism. The simple contemporary style is intended to blend with modern home décor.
Sopoby lists stainless steel construction and an adjustable latch for 2⅜- or 2¾-inch backsets. The knobs are described as reversible for left- or right-handed doors, and the stated door thickness range is 1⅜ to 1¾ inches. As with the other picks that use a square latch plate, that plate cannot be removed; check your existing hardware before starting installation.
This set is similar in purpose and pack size to the AEEKEL option. The key differences in the supplied specifications are the stated finish description and door-thickness range, so use your measurements to decide which fits better. The passage function is convenient for shared spaces but is not suitable when you need a door to lock.
Pros:
- Six knobs provide a matching set for multiple doors.
- Reversible design works with left- or right-handed doors.
- Adjustable latch accommodates two common backsets.
- Black contemporary styling suits a coordinated hardware update.
Cons:
- The square latch plate is not removable.
- Does not offer a privacy or keyed lock.
Verdict: Choose Sopoby for a six-door project if its listed door-thickness range and non-removable latch plate match your doors.
How to Choose a Door Knob With No Lock
Confirm that you need a passage knob
A passage knob keeps the door operable from both sides and does not provide a locking function. It is a good match for hallways, closets, and rooms where you do not need privacy. If the door is for a bathroom or bedroom and needs to lock, look for a privacy knob instead. For an exterior entry, choose a properly locking entry set rather than relying on a passage knob.
Measure the door thickness
Check the thickness of your door before ordering. The Probrico options and Sopoby set list a range of 1⅜ to 1¾ inches, while AEEKEL lists 1.38 to 1.78 inches. A knob that does not match the door thickness may not install correctly, so use the specific product’s measurements as your guide.
Check the backset
The backset is the distance from the edge of the door to the center of the knob hole. Each product lists compatibility with a 2⅜-inch or 2¾-inch backset. Measure your existing setup or check the current latch before purchasing, since the adjustable latch only helps if your door falls within those listed positions.
Look at the latch plate
All four listings specify a square latch plate that cannot be removed. If your door has a different latch shape or a different preparation, the new hardware may not be a straightforward swap. Compare the existing plate with the product details before you remove the old knob.
Choose a pack size for your project
The one-pack is suited to replacing a single knob, and the two-pack covers a pair of doors. The AEEKEL and Sopoby options include six knobs each, which can help keep hardware consistent across several rooms. Count the doors you plan to update so you do not buy substantially more—or less—than you need.
Match the finish to your other hardware
The products here have black or matte black finishes and round knob shapes. Finish descriptions can differ between listings, so compare the product images and details with your hinges, door stops, and other hardware. A consistent finish can make a multi-door update look more intentional.
Plan for straightforward installation, but verify fit first
The listings describe installation accessories or instructions, and several note reversible designs for left- or right-handed doors. Even so, fit depends on your door’s thickness, backset, and latch preparation. Check these details before beginning so you can avoid discovering a mismatch after taking the existing hardware apart.
Frequently Asked Questions
What is a door knob with no lock called?
It is usually called a passage door knob. It lets you open and close the door from either side without a key or privacy lock.
Where should I use a passage knob?
Passage knobs are commonly suited to hallways, closets, and other spaces where you want a door to latch but do not need it to lock.
Can I use a passage knob on a bathroom or bedroom door?
You can, but it will not provide privacy because it has no locking mechanism. If you need the door to lock, choose a privacy knob designed for that purpose.
Will these knobs fit any interior door?
No. Check the door thickness and backset for the specific product. These options list support for 2⅜- or 2¾-inch backsets, but the stated door-thickness ranges vary slightly.
What does an adjustable latch do?
An adjustable latch can be set for either of the two backsets listed by the product. It does not guarantee a fit with every door, so measure your existing hardware and check the latch plate style as well.
Are these knobs suitable for exterior entry doors?
They have no locking function, so they should not be used as a secure entry lock. For an exterior entrance, choose hardware that provides the level of locking you need.
Which option makes the most sense for several doors?
The AEEKEL and Sopoby sets each include six knobs. Compare their listed door-thickness ranges and latch details with your doors before choosing between them.
Final Recommendation
For one replacement, the Probrico single knob keeps the purchase simple; for two doors, its two-pack provides a matching pair. If you are coordinating several rooms, compare the AEEKEL and Sopoby six-packs against your door measurements and latch style. Whichever you choose, remember that a passage knob stays openable from both sides and does not replace a privacy or entry lock.
