Turramurra is home to some of the North Shore’s most beautiful older houses. Ku-ring-gai Council’s Ku-ring-gai Avenue Heritage Conservation Area, for example, is a collection of mainly Federation-era homes, many of them heritage-listed. These homes are full of character: solid timber doors, leadlight panels, double-hung windows and original brass hardware. They were also built long before modern security standards. As locksmiths based in Turramurra, Lock, Stock & Barrel Locksmiths is often asked the same question by owners of older homes: how do we make the house secure without spoiling what makes it special? This guide covers the common weak points in Federation and heritage homes, the upgrades that work well, and what to check with council before you start.
Common Security Weak Points in Older Homes
Original front doors with glass panels
Many Federation front doors feature leadlight or decorative glass in the door itself or in sidelights beside it. Those panels are part of the home’s charm, but if a lock can be opened with a thumb-turn on the inside, someone who breaks the glass may be able to reach through and open the door.
Old locks that have never been changed
Many older homes still have locks fitted decades ago. Some are simple latches that offer little real security. Others are worn to the point where they no longer lock reliably. And after many years and several owners, there’s often no telling how many keys are still out there.
Double-hung and casement windows
Double-hung sash windows and timber casement windows often rely on a basic catch or fastener. These can be weak, worn or missing altogether, and ground-floor windows at the back or side of the house are a common way in.
Side gates, sleepouts and outbuildings
Older properties often have deep blocks with side paths, rear gates, sleepouts, garages and sheds. Each one needs its own lock, and each one is easy to overlook.
Security Upgrades That Respect the Character of Your Home
Re-key the locks you already have
If your existing locks are in good working order, re-keying is often the simplest first step. It changes the internal pins so old keys no longer work, while the lock, its finish and the door itself stay exactly as they are. Our guide on why re-keying is a smart, affordable alternative to new locks explains when it’s the right choice.
Choose locks that suit timber doors
Solid timber doors are well suited to mortice locks, which sit inside a pocket cut into the edge of the door rather than on its surface. Because the lock body is hidden within the door, a mortice lock can add real strength with very little visible change. Fitting one well takes careful, accurate work on an original door, so it’s a job for an experienced locksmith. Our page on mortice lock installation goes into more detail, and our guide to types of door locks compares the main options.
Protect doors with glass, but keep a way out
For doors with glass in or beside them, a double-cylinder deadlock, which needs a key on both sides, stops someone reaching through broken glass to open the door. The trade-off is safety in a fire. Fire and Rescue NSW lists deadlocks among the security features that can slow an escape and advises making sure keys to all locked doors are readily accessible. If you choose double-cylinder locks, keep a key somewhere everyone in the house knows, but out of reach and out of sight of the glass.
Match the hardware finish
Modern security doesn’t have to look modern. Many quality locks and handles are available in traditional finishes such as polished brass, satin brass and darker bronze-style tones, so new hardware can sit comfortably alongside original features. Where an original handle or escutcheon is worth keeping, it can often stay in place while the lock behind it is upgraded.
Secure the windows
Keyed window locks and suitable restrictors can be fitted to many timber sash and casement windows, letting you lock a window shut or limit how far it opens while keeping its look. Our guides on installing window locks and window locks and restricted key systems explain the options.
Cut down the keys
Older homes tend to collect keys: front door, back door, sleepout, side gate, garage, shed. When you’re re-keying or replacing locks, it’s a good opportunity to have them set up on one key. A keyed-alike system means fewer keys to carry and fewer to lose.
Give valuables a secure home
Older homes rarely have anywhere secure to keep jewellery, passports and important documents. A wall safe can be installed discreetly, out of sight, without changing the look of the main rooms. Our guide to choosing the right wall safe covers sizing and placement.
Check With Council Before Changing Original Features
If your home is a heritage item or sits within a heritage conservation area, some changes may need council approval, particularly work that alters original fabric such as doors, windows or joinery. Ku-ring-gai Council explains that work needing development consent goes through a development application, while minor works and maintenance can go through a separate minor heritage works application, provided the work won’t harm the heritage significance of the property. Council’s heritage development controls and approvals page sets out the options. Council also notes that a Section 10.7 planning certificate will confirm whether a property is heritage listed.
Not every security job changes the building. Re-keying an existing lock, for example, only changes its internal pins. But if your plans involve cutting into original doors or frames, or replacing original windows or hardware, check with Ku-ring-gai Council first. We’re happy to talk through your options before any work starts so you can raise the right questions with council.

Frequently Asked Questions
Can I upgrade the locks on a heritage home?
In many cases, yes. Re-keying existing locks doesn’t change the building, and many modern locks and finishes suit older homes. If your home is heritage listed or in a heritage conservation area and the work would alter original doors, windows or hardware, check with your council before you start.
How do I find out if my home is heritage listed?
Ku-ring-gai Council advises that a Section 10.7 planning certificate will confirm whether a property is heritage listed. You can also contact council directly.
What is the best lock for an old timber front door?
A mortice lock is often a strong choice for a solid timber door, because the lock sits inside the door rather than on its surface. The right option depends on the door’s condition and thickness, so it’s worth having a locksmith assess it first.
Can I keep my original door handles?
Often, yes. Depending on the hardware, an original handle or escutcheon can stay in place while the lock behind it is upgraded or re-keyed.
