Door Locks
Ensure your doors are secure with our range of deadbolts, deadlocks, and combination locks as well as bathroom privacy locks. One of the main reasons for having doors in the first place, in addition to the pleasant appearance and preventing draughts and heat loss, is stopping people from just walking into areas they should not be allowed to. In a word, security (and sometimes, in another word, privacy). However, a door that only has hinges and handles is not very secure or private on its own – you need a lock for your door.
This is where our range of door security products comes in. From simple bathroom locks to deadbolts to digital combination locks and 3 lever and 5 lever deadlocks, we provide just what you need for any level of security. At their core, door locks are mechanisms designed to secure a door, preventing unauthorized access while allowing easy entry for those with the right key, code, or permission. They’re an essential part of daily life, found in homes, offices, and even industrial settings. But door locks are more than just functional tools - they’ve evolved over centuries into sophisticated devices that blend security with style.
Types of Door Locks
Door locks come in a variety of styles, each suited to specific purposes. Let’s explore the most common types and where they shine.
Deadbolts
Deadbolts are the gold standard for exterior doors. Unlike spring-loaded locks, they require a key or thumb turn to operate, making them tough to pick or force open. Single-cylinder deadbolts use a key on the outside and a thumb turn inside, while double-cylinder versions require a key on both sides—ideal for doors with nearby windows. Their strength makes them a top choice for front doors, though they’re less convenient for quick exits.
Knob Locks
Knob locks are a familiar sight in homes, often found on interior doors like bedrooms or bathrooms. They combine a handle and lock in one unit, with a keyhole on one side and a button or turn on the other. While they’re easy to use, they’re not the most secure option for external doors - burglars can break them with a hammer or wrench. For elderly users or kids, though, their simplicity is a plus, though safety concerns arise if little hands can reach them.
Lever Handle Locks
Lever handle locks offer a modern twist on traditional knobs. You push down to open them, making them easier to operate for people with limited grip strength - like the elderly or those with arthritis. They’re popular in offices and homes alike, but their exposed mechanism can be a weak point for security unless paired with a sturdy deadbolt. They’re best for interior doors or low-risk exterior ones.
Mortice Locks
Mortice locks are heavy-duty options often seen in older homes or commercial buildings. They’re installed into a pocket (or “mortice”) cut into the door, combining a latch and deadbolt in one robust unit. While they offer excellent security, they’re trickier to install and repair. They’re perfect for front doors or high-traffic areas where durability matters most.
Materials & Finishes
The material and finish of a door lock affect its durability, look, and cost. Here’s a rundown of the most popular options.
Common Materials Used in Door Locks
- Brass: A classic choice, brass is corrosion-resistant and naturally antimicrobial, making it great for high-touch areas. It’s often used in premium locks.
- Stainless Steel: Tough and rust-proof, stainless steel is a go-to for modern designs and outdoor locks exposed to the elements.
- Zinc Alloy: Affordable and versatile, zinc alloy locks are lightweight yet strong, though they may not last as long as brass or steel.
- Aluminium: Lightweight and budget-friendly, aluminium is common in basic locks but less durable for heavy use.
- Wood: Rare for locks themselves, wood is sometimes used in decorative elements, adding warmth to vintage styles.
Popular Finishes & Their Benefits
- Matt Black: Sleek and trendy, matt black hides fingerprints and pairs well with minimalist decor.
- Polished Chrome: Shiny and reflective, chrome resists tarnish and suits contemporary spaces.
- Satin Nickel: Soft and understated, this finish blends with most interiors and resists wear.
- Antique Bronze: With a weathered, old-world charm, it’s perfect for rustic or traditional homes.
- Brushed Brass: Warm and luxurious, brushed brass is making a comeback in 2025 for its subtle elegance.
Door Lock Mechanisms & Features
Understanding how locks work helps you choose the right one. Let’s break it down.
Passage vs Privacy vs Keyed Locks
- Passage Locks: No locking mechanism - just a latch to keep the door closed. Think closets or hallways.
- Privacy Locks: A simple lock (button or turn) for bathrooms or bedrooms, offering basic seclusion without a key.
- Keyed Locks: These require a key to lock or unlock, ideal for exterior doors or rooms needing extra security.
Deadbolt vs Cylinder Mechanisms
- Deadbolts: A solid bolt extends into the door frame, operated by a key or thumb turn. They’re top-tier for security.
- Cylinder Locks: Found in knob or lever locks, these use a spring-loaded latch. They’re less secure but easier to install and use.
Keyed vs Keyless Entry
Keyed locks are traditional and reliable, whilst keyless options - with codes, for example - eliminate the need for a key. Deadbolts (keyed or keyless), offer a level of security greater than spring-loaded cylinder locks.
Choosing the Right Door Lock
Factors to Consider When Buying Door Locks
- Door Type: Exterior doors need robust locks like deadbolts; interior ones can handle lighter options.
- Aesthetic Preferences: Match the lock to your decor - modern, vintage, or industrial.
- Security Needs: High-risk areas demand stronger locks; low-risk spots can go simpler.
- Ease of Use: Consider who’s using it - kids, elderly, or tech lovers.
Best Door Locks for Different Spaces
- Residential: Deadbolts for front doors, privacy locks for bathrooms, passage locks for living areas.
- Commercial: mortice locks for durability, smart locks for access control in offices.
- Industrial: Heavy-duty deadbolts or electronic locks for warehouses and factories.
Installation & Maintenance
How to Install a Door Lock: Step-by-Step Guide
Installing a lock can be a DIY job with the right tools: a drill, screwdriver, chisel, and measuring tape. Here’s the gist:
- Measure and mark where the lock will go (usually 36-38 inches from the floor).
- Drill holes for the lock body and latch, following the template provided.
- Chisel out space for the strike plate on the frame.
- Assemble the lock, secure it with screws, and test it. For complex locks like mortice or smart ones, a locksmith ensures precision
How to Maintain & Clean Door Locks
Keep locks working smoothly by:
- Wiping them with a damp cloth (avoid harsh chemicals on brass or chrome).
- Lubricating the mechanism yearly with graphite or silicone spray.
- Checking screws and tightening as needed to prevent rust or wear.
Door Lock Design Trends
Modern vs Vintage Door Locks
Modern locks lean minimalist - think sleek lines and smart tech. Vintage locks, with ornate details in brass or bronze, suit classic homes. Both are trending in 2025, depending on your style.
Trending Finishes & Colours for 2025
Matt black door locks and matt black door latches remains king, joined by brushed brass and mixed-metal combos for a bold look. Expect earthy tones like sage green in premium designs too.
Ergonomic & Universal Design Locks
Locks with larger levers or touchpads cater to accessibility, making them ideal for elderly or disabled users. Universal design is gaining traction for inclusive homes.
Security & Safety Considerations
How Secure Are Different Types of Door Locks?
Deadbolts and mortice locks top the security charts, especially with anti-pick features. Smart locks add layers like encryption, while knob locks lag for external use.
Fire-Rated & ADA-Compliant Door Locks
Commercial spaces need fire-rated locks that withstand heat and ADA-compliant ones with easy-grip levers for accessibility.
Childproof & Pet-Friendly Door Locks
Levers are riskier around kids (easy to open), while knobs are safer but harder for pets to nudge. Add lock covers for extra protection.
