Locks are essential for securing our homes, businesses, and valuables. With so many different types of locks available in the UK and worldwide, it can be challenging to determine which one best suits your needs. In this blog post, we will explore various lock types, including sashlocks, deadlocks, Euro cylinders, tumbler locks, camlocks, padlocks, and even smart locks from [Smart Locks Direct]( By understanding the unique features and benefits of each lock type, you can make an informed decision when selecting the perfect lock for your security needs.


Sashlocks, also known as latch locks, are a popular choice for securing doors in residential and commercial properties. These locks consist of a latch mechanism and a deadbolt, providing both convenience and security. The latch allows the door to stay closed without locking, while the deadbolt provides additional security when locked. Sashlocks are typically operated using a key or a handle and are available in various sizes and styles to suit different door types.


Deadlocks, also known as deadbolts, provide a high level of security for doors. Unlike sashlocks, deadlocks do not have a latch mechanism, meaning they can only be operated with a key. This lock type is ideal for external doors where maximum security is required. Deadlocks are available in single-cylinder and double-cylinder variants, with the latter offering additional protection against forced entry techniques such as lock picking and bumping.

Euro Cylinders

Euro cylinder locks are commonly used in UPVC and composite doors throughout the UK and Europe. These locks feature a pin tumbler mechanism housed within a cylindrical body, providing a high level of security. Euro cylinders are available in various sizes, finishes, and security features, such as anti-snap, anti-drill, and anti-bump technologies. Euro cylinders can be easily replaced without changing the entire door lock, making them a cost-effective solution for upgrading your door security.

Tumbler Locks

Tumbler locks, also known as pin tumbler locks, are one of the most common lock types used worldwide. These locks use a series of pins and springs within the cylinder to secure the lock. When the correct key is inserted, the pins align, allowing the lock to open. Tumbler locks offer a good balance of security and affordability and can be found in various applications, including door locks, padlocks, and camlocks.


Camlocks are compact, versatile locks used in various applications, including cabinets, drawers, mailboxes, and vending machines. These locks consist of a cylindrical body and a rotating cam that secures the lock when turned. Camlocks are available in different lengths, materials, and security levels, making them suitable for a wide range of uses.


Padlocks are portable, versatile locks that can be used to secure gates, sheds, lockers, and more. They come in various sizes, materials, and security levels, ranging from basic padlocks for low-security applications to high-security padlocks with advanced features like shrouded shackle protection and anti-drill plates. Padlocks can be operated using keys, combinations, or even smart technology.

Smart Locks

Smart locks are a modern, convenient alternative to traditional locks, offering keyless access to your home or business. These locks can be controlled using smartphones, key fobs, or biometric data, providing added convenience and security. Leading smart lock providers like [Smart Locks Direct]( offer a wide range of smart lock options, including retrofit solutions that can be easily installed on existing doors. Smart locks can also be integrated with home automation systems, allowing for remote access and monitoring.


Understanding the various types of locks available in the UK and worldwide can help you make informed decisions about your security needs. From the convenience of sashlocks and the high security of deadlocks to the versatility of padlocks and the modern convenience of smart locks, there is a lock type to suit every situation. Consider factors such as location, security requirements, and budget when selecting the perfect lock for your home or business.
