Types of door locks
Different types of door locks offer unique features and varying levels of security. By understanding these options, you can select a lock that not only meets your security needs but also complements your door's aesthetic.
Deadbolt locks
Deadbolt locks are known for their strength and durability. They work by extending a solid metal bolt into the door frame, preventing forced entry. As a result, this makes them one of the most secure types of door locks. They are typically used on external doors and come in single-cylinder and double-cylinder varieties, each offering different levels of security and convenience.
- Single-cylinder deadbolts: These locks are operated with a key from the outside and a thumb turn from the inside. They are easy to use but could be a security risk if there are nearby windows as burglars could break these and access the thumb turn. Despite this, they remain a popular choice for exterior doors due to their simplicity and ease of installation.
- Double-cylinder deadbolts: Double-cylinder locks require a key to operate from both the inside and outside, providing an extra layer of security. They are commonly used on external doors with glass panels or doors located near windows, preventing intruders from breaking the glass and gaining access. If you have this lock type, it’s important to remember to keep a key in an easily accessible location to ensure a quick exit in case of emergencies.
Mortise locks
Mortise locks are installed by fitting them into a pocket cut into the door, providing a higher level of security compared to other lock types. Thanks to their robust construction and intricate mechanism, mortise locks are highly resistant to tampering and forced entry, making them an excellent choice for both residential and commercial spaces.
Available in a variety of lever and knob styles, mortise locks offer flexibility in design while maintaining high security. Although the installation process can be more complex compared to other locks, the durability and strength of mortise locks make them a worthwhile investment for long-term safety and peace of mind.
Lever handle locks
Lever handle locks are commonly used for interior doors and require less force to turn than other lock types, offering smooth operation without the need for excessive twisting or gripping. The primary advantage of these locks lies in accessibility, making them a great choice for individuals with disabilities or the elderly. Consider pairing them with a more secure lock, as without this they may be vulnerable to forced entry.
Cylinder locks
Cylinder locks are one of the most common types of door locks used in both residential and commercial settings, offering easy installation and a high level of security. These locks operate using a key inserted into a cylindrical housing or cylinder, which contains pins that align with the key to allow the lock to turn.
Available in various types, including single-cylinder, (where a key is used on the outside and a thumb turn on the inside) and double-cylinder (where keys are required on both sides), cylinder locks provide flexibility for various needs. Cylinder locks are commonly used on exterior doors in homes and are available in various styles and finishes. This allows you to choose a solution to meet your security needs and aesthetic preferences.
Rim locks
Rim locks are mounted on the surface of the door and are often used in older homes. While they may not provide the highest level of security on their own, when paired with other locking mechanisms, such as a deadbolt, they can successfully enhance the overall security of a door. Known for their vintage appeal, rim locks add a touch of character to a home's entryway and are suitable for those looking to maintain a traditional aesthetic while ensuring a basic level of protection.
Multipoint locks
Multipoint locks are high-security locking systems commonly used on external doors. Unlike traditional locks that secure the door at a single point, multipoint locks engage at multiple points along the door frame – typically at the top, middle, and bottom. This multi-point locking mechanism enhances security by making it much harder for intruders to force the door open.
These locks are often operated by lifting the door handle and turning a key, which activates all the locking points simultaneously. Multipoint locks are particularly popular with uPVC, composite, and timber doors due to their superior strength, weather resistance, and ability to improve door alignment, reducing drafts and increasing energy efficiency.
Night latches
Night latches are surface-mounted locks typically used on residential front doors. Installed on the inside of the door, they use a latching mechanism that can only be opened from the outside with a key. From the inside, night latches are operated with a knob or lever, and many models include a snib button to hold the latch open or a deadlock for added security.
Popular for their ease of use, night latches automatically lock when the door is closed. They are ideal for high-traffic entry doors and are often paired with a deadbolt or mortise lock for enhanced security.
Electronic and smart locks
Electronic and smart locks provide enhanced security and convenience by removing the need for traditional keys. Instead, they use digital methods to control access to homes and businesses.
- Keypad locks: Operated using a numerical code to unlock the door, keypad locks eliminate the need for a physical key. Codes can be easily changed without needing to replace keys, making them particularly useful for families or businesses with multiple users.
- Smart locks: These locks connect to your smartphone via Bluetooth or Wi-Fi, allowing you to lock and unlock your door remotely. Many smart locks integrate with smart home systems for added convenience and security features. Smart locks offer advanced functionalities, such as temporary access codes for guests or deliveries, making them a versatile choice for modern homeowners.
Factors to consider when choosing a door lock
When selecting a door lock, it’s important to consider several factors to ensure it meets your specific needs. These include:
Security needs
Evaluate the security requirements of your home to determine the correct lock for you. Consider the location and the vulnerability of each entry point. Some doors require more robust security measures than others, depending on their location and exposure to potential threats. For example, a high-security lock, such as a deadbolt or smart lock, is typically the best choice for external doors, while interior doors may only need a simpler knob or lever handle lock.
Door material
Consider the material and thickness of your door, as this can significantly impact the effectiveness of a lock. Heavier, solid-core doors provide better support for high-security locks, while hollow-core doors may require additional reinforcement. For exterior doors, opting for a solid-core construction will maximise security.
Ease of use
It’s important to choose a lock that’s easy for all household members to use, especially in emergencies where quick access may be necessary. Whether you prefer using a key, a keypad, or a smart lock with app-based access, make sure you balance security with accessibility to find the right solution.
Budget
Locks are available in a wide range of price points, influenced by their security features, materials, and design. Determine your budget, then look for locks that offer the best combination of protection, durability and reliability within that range. Investing in a high-quality lock can save you from potential losses and offer peace of mind in the long run, rather than just opting for the cheapest option.
Aesthetic appeal
While the primary purpose of a lock lies in its functionality, they also play a role in the overall design of your home. Choosing a lock that complements your home's style can enhance the appearance of your doors while still providing maximum security. Consider the finishes and materials used in your home's décor and select locks that blend seamlessly with your interior.
Installation tips
Proper installation of door locks is essential for maximising security. Whether you’re installing the lock yourself or hiring a professional, these tips will ensure the process runs smoothly.
- Use the right tools: Before beginning the installation process, make sure you have all the necessary tools. Most lock installations require a drill, screwdriver, and chisel. Using the correct tools will reduce the risk of damaging the lock or door.
- Read instructions carefully: Understanding the specific steps and tools required to install your lock will help prevent any mistakes and ensure proper installation. Different locks have varying installation requirements so make sure you read the manufacturer's instructions thoroughly.
- Check alignment: Ensuring proper alignment of the lock and strike plate is essential for smooth operation. Misalignment can cause the lock to malfunction or become difficult to operate, which could compromise your security.
- Test the lock: Once the lock is installed, test it multiple times to ensure it functions properly and securely. By performing regular tests, you will identify potential issues early, allowing for timely adjustments or repairs.
Maintenance and care
Proper maintenance of your locks is essential for extending their lifespan and preventing malfunctions. Consider the following tips for maintaining your locks:
Lubricate locks regularly
Using a graphite lubricant will keep the lock mechanism operating smoothly. Regular lubrication prevents rust and corrosion, maintaining the lock's functionality over time.
Check for wear and tear
Inspecting locks for wear and tear regularly prevents more significant damage further down the line. It also ensures your locks continue to work as they should. If any parts appear worn or damaged, they should be replaced immediately.
Keep keys safe
Keys should be stored securely and hiding them in obvious locations close to the door should be avoided. Prevent unauthorised access by using a secure key storage solution, such as a key safe.
