Prospect has been a consistent landing suburb for Adelaide first-home buyers in recent years. The inner northern location — 5 kilometres from the CBD, well served by bus routes along Prospect Road and Main North Road — combined with a housing stock that offers genuine character at price points that, while significant, are somewhat more accessible than the inner southern suburbs, makes it a natural target for buyers who want established location and architectural quality.
The 2026 Prospect market has been competitive. Median house prices have moved past $1.6 million. First-home buyers entering this market are typically stretching their budget, and that creates a dynamic I see regularly: a significant amount of attention paid to the purchase price, conveyancing, building inspections, and finance — and almost none paid to the security situation of the property being purchased.
This guide covers what a locksmith would check in the first week of ownership of a Prospect home — and why the settlement period is the ideal moment to get this right.
Why Settlement Is the Right Time
The settlement period has a specific security characteristic that no other moment in the property lifecycle replicates: you are the first and only person who knows that a new owner has taken possession.
For a brief window after settlement — typically a few days to a couple of weeks — the previous owner may still have keys that open your home. Their real estate agent certainly had a key. Building and pest inspectors had a key. In some sales, multiple tradesperson quotes are obtained, and each of those tradespeople may have been given temporary key access. If the property has been vacant for a period before settlement, additional parties may have had access.
You don’t know the full key history of the property you’ve just bought. Nobody can give it to you completely. What you can do is close that history at settlement by rekeying, ensuring that from the moment you move in, you know exactly who can open your door.
A rekey at settlement is the single most important locksmith action a new Prospect homeowner can take, and it should happen before the removalists unload the truck.
The Settlement Security Checklist
Lock Type Identification
Before assessing whether locks are adequate, you need to know what type they are.
In Prospect’s bungalow stock, you may encounter original period mortise cases (bit key, lever-tumbler mechanism), early rim cylinder cases (profile key, surface-mounted), or any combination of modern deadbolts and passage latches that have been added to the property over its ownership history.
The key distinction is between a deadbolt (a bolt that requires a key to retract, providing real security) and a passage latch (a spring latch that can be pushed back without a key). If the front door has only a passage latch — a knob or lever with a spring bolt that doesn’t require a key to push back — it is not a secure door. In practice, every external door in a purchased Prospect home should have a working deadbolt before you move your belongings in.
Front Door Assessment
Check the front door deadbolt: does it shoot fully when the key is turned? Open the door and watch the bolt travel. It should extend cleanly to its full length — typically 20mm or more for a quality deadbolt. A bolt that stops halfway, catches against the strike, or can be pushed back with moderate finger pressure is not providing adequate security.
Check the strike plate: is it properly anchored? The screws should be long enough to reach into the stud frame behind the jamb — short screws that only engage the jamb timber can be defeated by a single kick. In Prospect’s older homes, this is a common situation; strike plates were often installed with 25mm screws into soft timber jambs. Upgrade to 75mm screws minimum, into solid backing.
Rear Door Assessment
The rear door on a Prospect bungalow or character home is the access point I find inadequately secured most often. The pattern is consistent: a quality (or at least visible) front door deadbolt, and a rear door with a rim lock, passage latch, or hardware that wasn’t updated when the front door was.
Test the rear door in the same way as the front: does it have a deadbolt? Does the bolt shoot fully? Is the strike plate properly anchored?
If the rear door opens to a rear yard accessible from the street or a lane, it is an external door in every meaningful sense and should be secured to the same standard as the front.
Window Security at Ground Level
In a Prospect bungalow, ground-level casement windows are a consistent security gap. The characteristic divided-pane casement windows — multiple small panes in a timber frame that swings outward — typically have original swivel-arm or cockspur fasteners. These hold the window in the closed position but resist almost no external force.
Check each ground-floor window:
– Does the fastener engage, or is it painted over, broken, or present but non-functional?
– Is the timber frame around the casement hardware intact, or is the timber soft or rotted?
– Is the window itself warped or gapped in a way that prevents it from closing fully?
Windows that can’t be fastened are windows that are open. In the first week of ownership, note which windows are currently non-functional fasteners and prioritise them for either repair (if a simple mechanical fix) or addition of secondary window locks (casement restrictors or equivalent).
Side Gate and Rear Lane Access
If your Prospect property backs onto the suburb’s rear lane system, the rear gate is a critical security point. Check what hardware is on it: a keyed slam lock (self-latching when the gate closes, key-operated from both sides) is the standard I recommend. A barrel bolt that can be reached over or under the gate is not meaningful security. A gate with no lock at all — just a latch — is essentially an invitation.
If the rear gate doesn’t meet this standard, adding a slam lock is a discrete and relatively inexpensive job that can be done independently of any other building work.
The Garage-to-House Internal Door
If your Prospect home has an attached or internally connected garage, the door between the garage and the main house interior requires specific attention. This door should be a solid-core timber or steel-faced door on a quality deadbolt. In many Prospect bungalows with attached garages, it’s a hollow-core door on a passage latch — the same security standard as an interior bedroom door.
Garage doors from the street are not impermeable — electric roller doors can be defeated with publicly available remote codes, and manual garage doors can be lifted with a wire through the emergency release gap. If the garage-to-house door isn’t deadlocked, a defeat of the garage door gives access to the main house interior.
Pro Tip: At settlement, request the full key history from the selling agent in writing — how many keys were cut, who received them, and whether any have been returned. You won’t always get a complete answer, but the request creates a documented record and often prompts an agent to arrange a rekey as part of the sale process if they haven’t already.
Rekeying: The Non-Negotiable First Action
I’ve said it above and I’ll say it again with more emphasis: rekey the property at settlement or immediately after. Before the removalists. Before the first night you sleep there.
In Prospect’s active resale market, properties often have ownership histories that include multiple purchases and tenancies. The lock on a Prospect bungalow at 64 Albert Street may have last been changed when the previous owners purchased it eight years ago. In those eight years, keys may have been given to cleaners, gardeners, a plumber, both sets of parents, a housesitter, a neighbour with a spare. None of those keys stop working when you purchase the property.
A rekey of the front and rear door of a standard Prospect home typically takes 45 to 60 minutes and costs $100 to $180. At the price points in this suburb, this is not a meaningful cost. It is, however, a meaningful outcome: from the moment the locksmith finishes, you know exactly who can open your door. That’s the starting point for actual home security.
A Job on Olive Grove
I was called to a property on Olive Grove — one of Prospect’s well-known residential streets — by a young couple who had just settled on their first home, a Californian bungalow they’d purchased after months of competitive searching. They called me the week after settlement, because they’d found a key in a kitchen drawer that didn’t match any key they’d been given at settlement.
When I examined it, it was a front door key — a period bit-key profile that opened the original mortise case on the front door. Neither the agent nor the previous owners had mentioned it. It had been in the drawer, presumably for years.
We rekeyed the front door cylinder (the property had both the original mortise case and a later-added cylinder deadbolt). We also assessed the rear door, which had an adequate deadbolt but whose strike plate screws were 25mm — not reaching the stud behind the jamb. We upgraded the strike plate anchoring on both external doors.
The couple’s comment: “We should have done this on settlement day. We just didn’t know it was a thing.”
Most first-home buyers don’t. That’s the purpose of this guide.
