Types of Door Locks
Knowing your options helps you choose the right level of protection for your home.
Mortice Locks
These are fitted inside the door and require a key to operate. They’re often used on back doors, and sometimes paired with a Yale lock on front doors.
Two Common Types:
-
Deadlock – Features a bolt and keyhole only
-
Sash lock – Includes a bolt, latch, and a pair of handles
Why Choose Mortice Locks?
There are several reasons for Cylinder replac:ement
-
First, they're difficult for burglars to force open
-
Second, they prevent intruders from escaping through a door after breaking in through a window
-
Finally, more levers mean greater key variation and higher security
We recommend 5-lever mortice locks tested to BS3621:2004. Most insurance companies require this as a minimum. You can easily identify a compliant lock by the British Standard Kitemark.
Cylinder Replacement - Rim Locks (Yale Locks)
These locks are mounted on the surface of the door. If your door locks when you shut it and opens from the inside without a key, it’s probably a Yale-style rim lock.
Key Features:
-
Typically used on front doors
-
Installed on the inside with the cylinder through the door
-
Convenient for everyday use
However, for better security, we recommend pairing a rim lock with a BS3621 mortice deadlock.
Cylinder Replacement - What We Do
If your keys are lost or stolen, we usually replace just the cylinder. We use high-quality cylinders and, where needed, upgrade to more secure models.
Consider Restricted Cylinders
These locks add extra protection by:
-
Preventing unauthorised key duplication
-
Requiring proof of ownership to cut new keys
This is especially useful in shared buildings or rental properties.
Extra Door Security
For added peace of mind, we can also fit:
-
Door chains
-
Door bars
-
High-security cylinders with anti-snap, anti-drill, anti-bump, and anti-pick features
These upgrades act as strong deterrents and physical barriers to intruders.
Window Locks
A Common Entry Point
Shockingly, 1 in 3 burglaries in the Romsey area happen through a window. That’s why securing your windows is just as important as securing your doors.
Where to Fit Locks
Focus on:
-
Ground floor windows
-
Windows near flat roofs or drainpipes
Even if a burglar breaks the glass, visible window locks can still stop them. They won’t be able to open the window easily, and most won’t risk crawling through broken glass.
Tip: Don’t leave window lock keys on show — store them somewhere out of sight but easy to reach.
