●        Screwdriver set – flat‑head and Philips, preferably with a magnetic tip.

●        Allen key set – many modern deadbolts use a hex socket.

●        Drill and drill bits – 6 mm and 8 mm for new holes if you’re upgrading to a larger cylinder.

●        Measuring tape – to verify back distance between the door edge & the centre of the bore.

●        Security paper or a door‑jamb template – handy for aligning the strike plate.

Step‑by‑step DIY guide for changing door locks new house

Here’s the practical rundown. Follow each step and you’ll have the job done in under an hour for a standard interior door.

1. Remove the existing lock

First, locate the two long screws on the interior side of the door. Turn them counter‑clockwise and pull the lock assembly out — If the screws are rusted, spray a little penetrating oil and give them a few minutes to loosen.

2. Check the bore and strike plate...

Measure the diameter of the hole in the door edge – it should be 13 mm for a typical deadbolt. If it’s oversized, you’ll need to fill it with wood filler and re‑drill. Align the strike plate on the frame; the gap between the plate and the door edge should be no more than 2 mm.

3 — Install the new deadbolt

Insert the new deadbolt cylinder into the bore, making sure the tailpiece sits flush against the door edge. Secure it with the supplied screws, tightening them just enough to avoid stripping the wood.

4. Fit the strike plate

Place the strike plate on the jamb, line up the latch hole, & screw it in with 3‑mm wood screws. For high‑traffic doors, use longer 4‑mm screws that go into the framing studs for extra hold.

5. Test the lock

Close the door & turn the key or press the thumbturn. See the latch should slide smoothly & the deadbolt should extend fully. If it sticks loosen the strike plate a millimetre and try again.

And that’s it – you’ve successfully completed changing door locks new house without a professional.

●        Deadbolt (single‑cylinder) – the most common for front doors; works well in temperate zones like Adelaide.

●        Deadbolt (double‑cylinder) – better for high‑risk areas such as Perth’s inner suburbs; requires a key on both sides.

What typically happens is that homeowners pick a deadbolt for the main entrance and a simple latch for internal doors. That gives you layered security without over‑complicating the set‑up.
