A door cylinder lock, often just called a cylinder lock, is a lock mechanism that revolves around a cylinder. This cylinder is the main part of the lock, interacting directly with your key. When you insert and turn your key, the cylinder activates, either locking or unlocking the door, allowing you to secure your home or enter it.

Modern high-security door cylinders, such as the Avocet ABS, Ultion Lock, and Yale Platinum, are designed using cutting-edge technology and robust materials to provide an elevated level of home security.
Here are some key features that make these locks so secure:
Anti-Pick Technology: These locks are engineered with intricate pin configurations and unique anti-pick features that make it extremely difficult to pick.
Increased Number of Pins: Most locks have 5 or 6 pins, but with a higher pin count, these locks offer a vast number of key combinations, making them incredibly difficult to pick or bump. The Ultion lock has 11 pins.
Multiple Sacrificial Layers: Some cylinders have multiple sacrificial layers rather than just one. In the event of an attack, these layers break off to protect the core of the cylinder, ensuring the lock remains secure even under duress.
Internal Strength: The internal mechanisms of these locks, crafted from robust materials, provide a level of strength that resists forceful attacks
Anti-Drill and Anti-Snap Features: Specialised hardened steel elements and reinforced bars make these cylinders resistant to drilling and snapping.
Magnetic and Dimple Key Technology: Modern keys often incorporate magnetic and dimple technology, providing a higher level of key control and making the locks harder to pick as well as much harder to copy.
Key Control: High-security cylinders often have patented key systems, ensuring keys can only be copied with the proper authorisation.
Visual Deterrence: The mere presence of high-security locks, identifiable by their distinct branding, can act as a deterrent to potential intruders.
Investing in a high-security door cylinder like the Avocet ABS, Ultion Lock, or Yale Platinum is a prudent choice for those seeking to significantly enhance their home security.
Most locks on doors are very easy to take out and measure. On most UPVC and composite doors there will be a screw on the side of the door that screws into the cylinder.
With a tape measure, measure from the external side of the cylinder to the centre of the screw hole and do the same from the internal side of the cylinder.
You will end up with two numbers that may or may not be the same, i.e 45mm (internal) and 55mm (external), so this means your cylinder is 100mm in length but is offset, so you need to get a cylinder that is 45mm internal and 55m external.
It’s also worth noting that if your cylinder sticks out or is proud from the external handle, you can go for a smaller external sized cylinder, i.e if it sticks out 10mm from the external handle and the external size to the screw hole is 55mm, you can get a 45mm external cylinder and this will then sit a lot flusher with your handle, increasing security.
Ensure the door is unlocked and opened.
Locate the screw on the side of the door, usually a phillips type. With the correct screwdriver, undo and remove the screw, keeping it in a safe place.
Insert your key into the lock, turn it to 10 o'clock or 2 o’clock and pull the cylinder out.
Ensure the anti-snap side faces externally; if dual anti-snap, look for 'EXT’ marking on the cylinder.
Insert the key into the cylinder and turn it to align the black centre cam flush within the cylinder.
Insert the cylinder into the door and position the cylinder centrally, reinsert and tighten the screw securely to hold the cylinder in place.
