Black Door Knob 5-Pack Keyed Alike Entry Locks - Matte Black

In this review of the Haidms 5-pack keyed alike door knobs the bottom line is simple: this set is for homeowners or small businesses that want an inexpensive way to standardize keys across multiple exterior or interior entry points. The biggest reason to buy is the convenience of having five ball-style knobs keyed the same, with 15 identical keys included, which saves time and pocket clutter. Installation is straightforward and designed for DIYers, and the set works well where moderate security and consistent access across doors is more important than premium lock hardware.

Key Features

• Keyed alike set: Five knobs come keyed the same so one key opens multiple doors, reducing the number of separate keys to carry.
• Entry lock functionality: Each knob locks from the outside with a key and locks from the inside with a turn button for quick privacy and security.
• Adjustable fit: The latch adjusts to fit 2-3/8' or 2-3/4' back sets and the knobs fit doors 1-3/8' to 1-3/4' thick, covering most residential doors.
• Universal handing: Designed for both right-handed and left-handed doors so the same set can be used throughout a home or office.
• Simple installation: Replacement installation requires only a Phillips screwdriver, so most users can fit the knobs without hiring a pro.
• Extra keys included: The package supplies 15 identical keys, giving spares for family members or backup use.

Who It's For

This set is best for property owners who need a functional, affordable solution to unify door access across several entrances, such as rental units, a family home, or a small office. It is especially useful when convenience and consistent access are priorities, and when you want to avoid carrying multiple keys for interior and exterior doors.

It is not aimed at users who require high-security, commercial-grade locks or specialized features like electronic access control. If you need heavy-duty tamper resistance or premium materials, consider a higher-end lockset from a security-focused line.
