Spring Knob Locks: Secondary handles and Locks for your entrance doors

Spring knob door knob

A spring knob handle is a common type of door handle that uses an internal spring and latch. When you turn the knob, the latch pulls back to open the door and then automatically springs back into place when released. These handles are often used on entry doors along with a deadbolt for extra security. Available in locking or non-locking styles.

Keyed entry door knobs

Spring knob handles for exterior doors feature a key lock on the outside and a turn button or thumb turn on the inside, allowing easy locking and unlocking from either side. They’re ideal for front, back, and garage entry doors and come in single-cylinder (keyed outside, turn inside) or double-cylinder (keyed on both sides) options. While they can secure a door on their own, they’re most often installed below a deadbolt for a complete and reliable locking system.

Front door thumb-controlled spring knob handles

Front doors often feature spring knob locks with a small thumb-press lever above the handle. Pressing the lever downward retracts the spring-loaded latch, allowing the door to open without twisting the knob. This design combines ease of use and the security of a traditional spring knob lock with a classic, polished look that complements a wide range of exterior styles.

Smart-key and re-keying convenience

A smart key or re-key system is a modern keyed knobset technology that allows homeowners to quickly change the key that operates a lock without removing the lock or calling a locksmith. Systems like SmartKey let multiple exterior doors be reprogrammed to work with a single key in seconds, providing convenience and enhanced control over home entry. This feature is especially useful for homeowners who frequently change access, such as when replacing tenants or updating security, though very few companies offer it, making it a relatively rare and premium option.

Styles and finishes

Spring knob handles come in a wide range of styles and finishes to suit both traditional and modern homes. The right style can enhance curb appeal and coordinate with your other exterior hardware.

• Traditional Round Knobs: The most common and familiar shape, often used for classic or colonial-style homes.
• Decorative or Fluted Knobs: Feature sculpted detailing for a more elegant, heritage-inspired look.
• Contemporary Smooth Knobs: Clean, minimal designs ideal for modern or transitional homes.
• Lever-Style Knob Hybrids: Combine the round knob with a short lever or thumb control for easier use.

Most manufacturers offer finishes that coordinate with deadbolts and door accessories, including satin nickel, polished chrome, matte black, brass, and oil-rubbed bronze. Choosing the right finish can tie together the look of your front, back, and garage doors.

Smart knobsets and connected security

Smart technology has made its way into spring-knob handles too. Smart knobsets combine traditional design with modern access features such as keypads, Wi-Fi connectivity, and fingerprint recognition. They can be locked or unlocked remotely through a smartphone app, or programmed to issue temporary access codes for guests or service providers.

• Keypad or app-based access for front and back doors
• Wi-Fi or Bluetooth connectivity for remote control
• Temporary or scheduled codes for guests or family members
• Backup key option for power or connection loss

Pros and cons of spring knob handles for entry doors

Advantages

• Classic, familiar appearance for most homes
• Affordable and easy to install or replace
• Compatible with many smart key systems
• Available in finishes that match deadbolts and door hardware

Limitations

• Less secure than a deadbolt on its own
• Can be easier to force open if used without additional reinforcement
• Smart versions require batteries and occasional maintenance
• Not always covered as a primary lock by home insurance policies

Because of these factors, most homes use a keyed or smart knob handle for daily convenience and a deadbolt for added protection. This combination offers both easy access and dependable security.

Choosing the right knobset for your home

When selecting a knobset for your exterior doors, consider both function and security. Look for hardware that complements your home’s style and provides the right level of protection.

• Check ANSI/BHMA ratings for durability (Grade 1 or 2 recommended)
• Confirm compatibility with your door thickness and latch type
• Decide between mechanical, re-keyable, or smart knobsets
• Choose finishes that match your hinges and door handles

Final Thoughts

Spring knob handles are a familiar and functional part of every home. Whether you prefer a traditional keyed knob or a smart connected version, pairing it with a quality deadbolt ensures your front, back, and garage doors stay secure while maintaining everyday convenience.
