How do oval cylinder locks work?

These locks work like any other, however, it’s the details that matter. Understanding how they work can shed light on their effectiveness so you can decide if they’re the right fit for your doors.

Components of an oval cylinder lock

For you to comprehend the functioning of the oval profile cylinder lock, it’s essential first to familiarise yourself with their main components:

Cylinder – The core component is the cylinder itself. This cylindrical-shaped structure houses the internal mechanisms, including pins and springs;
Keyway – The keyway is the slot or groove on the outer side of the cylinder, where you insert the key;
Key pins – Key pins are tiny metal pins located within the cylinder. These pins vary in size and align with the cuts on the key;
Driver pins – Positioned above the key pins, driver pins interact with the key pins and engage with the key to keep the lock secure;
Cam – The cam is the rotating part of the lock that engages with the door mechanism. When this component is engaged, the lock stays firmly in the lock cavity;
Faceplate – The visible plate on the edge of the door with the keyhole is known as the faceplate. It this case it’s oval.

How oval cylinder locks work

Each time you insert the correct key into an oval lock, the following sequence of actions occurs:

Key insertion – The notches on the key lift the key pins and driver pins to the correct height, aligning them along the shear line;
Rotating the key – The aligned pins create a gap at the shear line, allowing the cam to rotate. This rotation activates the locking or unlocking mechanism connected to the door;
Locking/unlocking – The turning of the key either engages or disengages the locking mechanism, securing or releasing the door.

Benefits of oval locks

With their unique design and functionality, these locks have several advantages for you to consider:

Increased key combinations – Oval cylinder locks often have a higher number of possible key combinations due to their elongated design, making them more secure;
Improved key control – The shape of oval keys and keyways allows for better key control, limiting unauthorised key duplication;

When it comes to choosing the right cylinder lock for your needs, two popular options often stand out: oval cylinders and euro cylinders. This section will help you distinguish between these choices and determine which one best suits your specific requirements.

An oval cylinder, as the name suggests, has an oval shape and typically works alongside an oval mortice lock case. On the other hand, an euro cylinder resembles an enlarged keyhole shape and is designed to complement an euro mortice lock case. Oval cylinders and euro cylinders might appear similar at first glance, but their differences go beyond just their visual shapes:

Unique shape, and enhanced security – Oval cylinders are renowned for their distinctive design. Their non-standard oval shape adds an extra layer of security. This unique configuration makes them formidable against picking and manipulation;
Resistance to drilling and bumping – Oval lock cylinders are built to withstand common break-in techniques, including drilling and bumping. Their design and construction make them resilient in the face of these threats;
Versatile compatibility – These locks are highly compatible with various door types, such as wooden, metal, and, as you already know, glass doors. This versatility makes oval cylinder locks an excellent choice for different applications.

Oval cylinder locks offer diverse solutions to meet specific security needs. Let’s navigate through the primary types of oval lock cylinders, providing an overview of each.

Single-cylinder oval locks

These oval locks are equipped with a keyhole on one side, while the opposite side features a knob or thumbturn. Often found in residential spaces, they provide basic security, allowing keyless access from the inside.

Double-cylinder oval locks

Double-cylinder oval locks feature keyholes on both sides, enhancing security. Commonly installed at the main entrances of homes, these locks are crucial for safeguarding high-traffic areas. However, they require consideration regarding safety during emergencies.
