What is a deadbolt?
A deadbolt is designed with security in mind. Unlike spring locks, it cannot be moved into the open position without a key or the interior thumb turn. That makes it much harder for intruders to force open. Deadbolts are the standard for exterior doors in homes across Canada.
Tip: For maximum security, choose a high-quality deadbolt with a heavy-duty strike plate and screws long enough to reach the wall stud.
Deadbolt types & styles
Deadbolts offer a higher level of security for your home and come in a variety of types and styles to suit different entry points and design preferences:
Types
Single-cylinder deadbolts
The most common choice for residential doors. Operated with a key from the outside and a thumb-turn on the inside, they provide a strong layer of security while remaining easy to use.
Double-cylinder deadbolts
Require a key on both sides. They are ideal for doors with glass panels or sidelites near the lock since an intruder can’t simply break the glass and reach in. However, they may raise safety concerns in an emergency exit situation, so placement and use should be considered carefully.
Lockable thumb-turn deadbolts
Offer the convenience of a standard thumb-turn on the inside, but with the added ability to lock the thumb-turn itself with a key. This gives you extra peace of mind when you’re away from home for longer periods.
Digital/Smart deadbolts
A modern solution that combines convenience with advanced technology. These locks can be operated through a keypad, smartphone app, or even biometric entry (such as fingerprints). Many models include a traditional key backup to ensure you’re never locked out.
Styles
Standard cylindrical
A timeless, functional choice that blends seamlessly with most door designs.
Square or rectangular
Designed with clean lines and a geometric profile, perfect for a modern or minimalist home aesthetic.
Decorative
These deadbolts come in a wide variety of finishes and patterns, often paired with matching handlesets for traditional, period-style, or high-end homes.
Keyless digital
Sleek and streamlined, these styles complement contemporary interiors and exteriors while eliminating the need for keys altogether.
Available in finishes like brass, nickel, bronze, black, and chrome, deadbolts can be selected to complement your home’s style while providing robust security for exterior doors.
What is a spring knob lock?
A spring lock (sometimes called a latch lock) is convenient because it typically locks automatically when the door closes, though some models are designed only to latch without locking. These locks are commonly found on doorknobs and lever handles. While spring locks offer ease of use, they’re not as secure on their own because the latch can be forced open.
Tip: If you rely on a spring lock, always combine it with a deadbolt for stronger security.
Spring Knob types & styles
Spring knob locks come in a range of types and styles, allowing homeowners to balance convenience, security, and design:
Types
Non-locking (passage knobs)
Functions as a simple latch with no locking mechanism. Perfect for hallways, closets, and other areas where privacy isn’t needed.
Privacy knobs
Locks from the inside with a push button or turn mechanism, making them ideal for bathrooms and bedrooms. They provide privacy without requiring a key.
Keyed entry knobs
Lockable from both sides with a key, commonly used on entrance doors or back doors. For stronger protection, they’re often paired with a deadbolt.
Storeroom knobs
Always locked from the outside, requiring a key to enter, but allowing free exit from the inside. Typically used in commercial or utility settings where controlled access is important.
Classroom knobs
Can be locked or unlocked from the outside with a key, but have no interior locking option. This type is more common in schools and institutions, though occasionally seen in specialised residential uses.
Styles
Round knobs
A traditional and familiar design, suited to a wide range of doors and home styles.
Egg-shaped knobs
A traditional and familiar design, suited to a wide range of doors and home styles.
Tulip knobs
Featuring a flared, decorative shape, tulip knobs were especially popular in older homes and continue to be used in vintage-inspired interiors.
Ball knobs
Smooth, minimalist, and highly versatile. Their simple design makes them easy to integrate into both modern and classic spaces.
Decorative knobs
Available in ornate designs and finishes to match specific architectural looks — from traditional to high-end custom homes.
With multiple types and styles available in finishes like brass, nickel, chrome, bronze, and matte black, spring knob locks can be matched to both your security needs and aesthetic preferences.
Pairing deadbolts with spring locks
Most homes use both a deadbolt and a spring lock on entrance doors. The deadbolt adds reliable protection, while the spring lock provides everyday convenience. Spring handle locks combine a lever-style handle with a spring latch and can be locking, with a keyed exterior, or non-locking, serving only as a latch.
