What Are the Different Types of Door Locks in the UK?
There are many types of door locks available in the UK, including mortice locks, cylinder locks, night latches, multi-point locks, deadbolts, smart locks, and rim locks. Each lock type offers different levels of security and convenience, helping you choose the best system for your home or business.
When it comes to keeping your home safe, your door lock system is your first line of defence. Whether you’re securing a front door, internal door, or commercial space, the right lock can make all the difference.
From traditional key locks to smart electronic systems, there’s now a wide range of door lock types available in the UK. In this guide, we’ll walk you through each option - explaining how they work, where they’re best used, and which ones we recommend from the Door Security Collection at WME.
Why Door Locks Matter
A reliable door lock does more than protect your home - it gives you peace of mind. Modern homes often mix traditional and digital security, combining easy door locks with advanced smart technology.
Choosing the right lock depends on where it’s installed, how much protection you need, and whether you prefer a key lock or a keyless system. Let’s explore the most popular door lock types in the UK and how to choose the best one for your needs.
1. Mortice Locks
Mortice locks are fitted inside the door itself, making them one of the most secure types of mechanical locks. Most often used on wooden front or back doors, these locks are available in 3-lever (for internal doors) and 5-lever deadlock versions, which meet insurance-approved British Standards (BS3621).
If you live in a house with a lock on a timber door, a mortice lock is likely what you have. WME stock magnetic mortice locks by CDVI, as well as several smart and access control systems that provide the same high level of protection with added convenience.
2. Cylinder Locks (Euro, Oval & Rim)
Cylinder locks - particularly Euro cylinders - are extremely popular in modern uPVC and composite doors. They’re easy to replace, come in various security grades, and are often used with multi-point lock systems.
Look for anti-snap, anti-pick, and thumb-turn models for better safety and convenience. These are ideal for anyone wanting an easy door lock upgrade without replacing the entire mechanism.
3. Night Latches
Commonly found on older UK homes, night latches (often called Yale locks) are mounted on the inside of the door and automatically lock when it’s closed. While they’re handy for quick entry and exit, they work best when combined with a deadbolt or secondary safety lock for front doors.
At WME, we recommend upgrading to a smart access control system for greater security and convenience.

4. Smart Locks
Smart locks are transforming home security. With keyless access, app control, and even voice commands, these locks allow you to lock and unlock your door remotely. Many models integrate with security systems, video doorbells, or smart hubs for complete peace of mind.
They’re ideal for anyone looking to modernise their home door locks without compromising safety. Brands like Optimus, Ajax, and TP-Link offer smart lock systems available from WME.

5. Multi-Point Locking Systems
If your door locks in several places when you turn the key, it’s likely a multi-point locking system. Common on uPVC or composite doors, these mechanisms secure the door at multiple points - top, middle, and bottom - for excellent resistance to forced entry.
When paired with an anti-snap cylinder, this type offers one of the best door lock systems in the UK.

6. Deadbolts
Simple yet extremely secure, deadbolts are a great way to add extra security for front doors. They can be used alone or as a secondary lock alongside a latch or smart system.
Single-cylinder deadbolts can be opened with a key from the outside and a thumb-turn inside, while double-cylinder versions require a key on both sides for maximum security.
🔗 WME recommends the CDVI Motorised Deadbolt Lock. It securely locks heavy-duty doors and cages and comes with a circular key cylinder along with 3 keys compatible with door/gate thicknesses of 40-90mm.
7. Rim Locks & Rim Deadlocks
Rim locks are surface-mounted and often used on internal doors with keys or garden gates. While they’re not as secure as mortice or multi-point locks, they’re useful for low-risk areas or secondary doors.
If you’re looking for a simple door lock solution, this is a reliable, affordable choice.
8. Keyless & Digital Entry Systems
For convenience and control, keyless door locks let you manage access via PIN codes, cards, or smartphones. Ideal for offices, rental properties, or smart homes, they provide the flexibility to lock a door or grant access remotely.
Trusted brands such as Ajax, CDVI, Hikvision and Texecom stock a wide range of keyless door lock options at WME.

9. Chain Locks & Door Reinforcement
Even the strongest lock benefits from extra reinforcement. Door chains, bolts, and reinforcement bars are simple add-ons that offer an extra layer of protection. These physical deterrents are perfect for anyone searching for extra security for their front door.

10. Padlocks
For sheds, gates, or storage areas, padlocks provide portable security. Choose from keyed or combination options depending on your needs. They’re ideal when you need a lock system that’s flexible and easy to move between locations.
Choosing the Right Door Lock
When choosing the right home door lock, think about:
- The type of door (wood, uPVC, composite, or metal)
- The level of security required
- Whether you want a key lock or a smart keyless system
- Compliance with UK safety standards (BS3621, TS007, etc.)
Combining physical and digital protection is the best way to keep your property secure - especially for your front door, where visibility and strength matter most.
