the most common type of door lock 

Door locks are an essential part of keeping our homes and businesses safe. 

But with so many types of door locks available, it can be hard to know which one is right for your needs. In this article, we’ll discuss a range of popular door lock types and explain the features that make them suitable for different security requirements. We’ll also look at what British Standards BS3621 means for mortice locks and provide tips on how to choose the best door lock for your needs. So let’s get started!

Overview of Door Lock Types

Regarding door locks, there are many different types to choose from. Depending on the level of security, cost, and aesthetics wanted, selecting the best door lock for your needs is essential.

Mortise locks are one of the most popular types of door locks in the UK. These locks have a keyhole that’s cut into the edge of a door and secured with a latch or bolt inside. 

The mortice lock is then held into place with two screws and typically has either two or three levers which must be turned before the lock can be opened.

Deadlocks are another popular type of door lock, usually used as an extra layer of security on external doors. 

They feature an internal mechanism that must be manually operated with a key from both sides and cannot be easily forced open by intruders.

Rim locks are generally considered less secure than other types of locks as they use a flat key rather than one with teeth – making them easier to pick open without a key.

 However, they still provide some degree of security if installed correctly and make it harder for intruders to gain access without detection.

Cylinder locks are commonly used in UPVC doors due to their simplicity and ability to be installed quickly and easily. This type of lock features an internal cylinder that must be turned in order for it to operate correctly – making it more difficult for burglars to break in than other types of locks.

Multi-point locking systems offer increased levels of security over single-point locking systems by providing multiple points (usually three) where the lock engages with itself when locked shut – making it much harder for an intruder to force entry through this type of locking system compared to others.

In addition, British Standard BS3621 requires at least 5 levers in any mortice lock used in the UK – meaning that all mortice locks must meet this standard before they can be sold legally within the country[5]. It’s therefore important that anyone looking to install new or replace existing mortice locks checks whether they meet this standard first before purchasing them or arranging installation by a professional locksmith.

Knowing which type of lock is right for you will depend on factors such as the level of security required, cost constraints, aesthetic considerations, etc., so consult with a professional if you’re unsure what kind is best suited for your needs or have any questions about installation requirements, etc..

Lever Mortice Deadlocks

The 5 Lever Mortice Deadlock is a reliable and secure lock that can be found on many residential doors in the UK. This type of lock is resistant to manipulation due to the five levers which must be aligned correctly in order for it to unlock. It also complies with British Standard BS3621, which requires mortice locks contain at least five levers. Its rectangular shape makes it easy to identify, and you’ll often find them on uPVC doors, wooden doors, and composite doors.

This particular deadlock consists of two parts: the box section with a keyhole on one side and an internal latch for locking/unlocking from the inside; as well as a striker plate which fits into the frame of the door when closed. It's important to remember that changing or installing this kind of lock requires professional locksmith services - someone who is qualified can ensure your new deadlock meets security standards and is installed correctly according to manufacturer guidelines while complying with relevant regulations such as BS3621. If you are thinking about upgrading your existing locks or installing a new one then contact a local approved locksmith who will advise you on what solution best suits your needs whilst maintaining security standards.

To summarise, investing in high-quality door locks is essential for protecting your property against unauthorised access. The 5 Lever Mortice Deadlock provides superior security features whilst meeting all requirements set out by British Standard BS3621; however it’s integral that professional locksmith services are used when installing or changing any kind of door lock for optimum safety measures.

Multi Point Locking Systems

Multi Point Locking Systems are becoming an increasingly popular choice for providing extra security to doors. Thanks to its multiple locking points, it is much more difficult for someone to gain entry by forcing or manipulating the door. Furthermore, these systems can be operated by a single key instead of several different ones.

These locks come in a range of sizes and finishes that can be tailored to suit any application, from residential homes to public spaces such as offices and retail stores. Moreover, their design also meets UK fire regulations, making them a safe option for use in high-traffic areas.

Despite the superior protection it offers compared with traditional mortice locks, Multi Point Locking Systems require regular maintenance due to their complexity and numerous moving parts. For this reason it’s essential that installation is done professionally by a qualified locksmith who has experience with this type of lock. That way you can ensure your system is fitted correctly and works properly when you need it most.

Overall, Multi Point Locking Systems offer excellent protection against forced entry while also meeting UK fire regulations – making them suitable for virtually any application where additional security is desired. However, they do require more maintenance than other types of locks so proper installation and inspections should always be carried out by an experienced professional in order to ensure optimal performance from these systems.

Euro Cylinder Locks

Euro cylinder locks are a popular type of lock found in many homes and businesses across the UK. They are easy to fit, making them ideal for DIY installations, and come in a variety of sizes and levels of security. The most secure euro cylinder locks meet British Standard BS3621, which requires at least 6 pins for an anti-snap feature.

When choosing a Euro Cylinder Lock for your door, you should consider the size of the cylinder as well as its security features. Most cylinders come in three different lengths - 40mm (standard), 50mm (long) and 60mm (extended). If you’re not sure what size you need for your door, consult a professional locksmith who can measure the existing lock or advise on the best length for your needs.

In terms of security features, look out for euro cylinder locks with anti-pick, anti-drill, and anti-bump features. These will help prevent burglars from picking or drilling through your door lock. Additionally, make sure that any euro cylinder you choose conforms to British Standard BS3621 – this is essential if you want to maximize your security levels.

For optimal performance and peace of mind, it’s best to have professional locksmith services when installing or changing euro cylinders – they will ensure that everything is installed correctly and securely so that you don’t have to worry about potential problems down the line. When selecting a professional locksmith service provider, be sure to check their credentials carefully before engaging them – reputable services should be able to provide references from previous customers if needed.

In conclusion, Euro Cylinder Locks offer great versatility when it comes to fitting door locks into different types of doors or frames due to their range of sizes available and excellent security features when conforming with BS3621 standards. While these can be installed yourself if you have some DIY experience, it is always best practice to consult a qualified professional who can guarantee quality installation services that you can trust over time.

Other Types of Door Locks and British Standard BS3621

When it comes to door locks in the UK, there are a variety of options available other than those that conform to British Standard BS3621. 

Night latches, rim locks and sash locks can all be beneficial for additional protection, but may not offer the same level of security as a mortice lock.

Night latches are fitted with an automatic deadbolt that is released when turning the handle from the inside; whereas rim locks feature a latch bolt which is opened by either side of the door. Sash locks, on the other hand, contain two bolts - one deadbolt and one latch bolt - operated by a single handle commonly used on windows or doors.

To ensure these types of door locks remain secure over time, regular maintenance is necessary; inspecting all parts of your lock and making repairs or replacements if required. If you need extra protection for your property or belongings then investing in higher-quality materials or specialist locking systems could be worth considering too.

When selecting any type of door lock it's important to think about what kind of access control measures you need for each area and select accordingly; night latches may suit simple intrusion prevention but Euro cylinders could better secure external doors while rim locks might be more suitable for internal ones. 

Don't forget to consult with a professional when installing or changing your lock too; this ensures everything fits together correctly so that your chosen system provides maximum security against forced entry attempts.

 A reputable professional will also be able to advise on any additional measures that would further improve safety (such as window bars). Investing in quality products and installation services will give you peace of mind knowing that everything has been properly fitted - so always seek expert advice!
