Best Key Lock Boxes in Australia (2026)

Why a key lock box beats every other hiding spot

Because the alternatives are worse. A key under the mat, on the meter box or inside a fake rock is the first thing anyone checks, and in a typical Australian street those spots are visible from the footpath. A key lock box moves the problem from where do I hide this to who gets the code, and a code is something you change on a Sunday afternoon without calling a locksmith.

This guide covers seven mechanical key lock boxes and key safes sold on Amazon Australia, from a small wall unit for two house keys to an oversized box that swallows a car fob. Prices start under $30 and climb past $75. The differences that matter are mounting method, internal room and whether the listing gives the box a weather rating at all, and we compared all three across every pick.

What is the best key lock box in Australia?

For most homes it is the Master Lock 5401D Wall Mount Key Lock Box. It bolts to a wall with the hardware supplied, takes five keys, runs a set your own resettable code, and the listing rates the body weather resistant with an anti corrosion finish. At 227 g it is the lightest of our seven picks, which sounds like a downside until you are holding it against brick with one hand and a drill in the other.

If you rent, the Master Lock 5400D Portable Key Safe hangs over a door knob or gate rail instead. It has an 83 mm metal body, a weather shutter over the dials, a limited lifetime warranty on the listing, and many times more customer reviews than any other pick here.

Spending as little as possible? The Fayleeko LBWH-802 Wall Mounted Key Lock Box is the cheapest of our seven picks, mounts to a wall or hangs from a shackle, and its listing carries a waterproof rating that five of the seven do not.

How do these key lock boxes compare?

Read the weather rating column first: it is the specification most buying guides skip and the one that decides whether a box survives a summer on a west facing wall. Not stated means the listing describes outdoor use without giving a water resistance level.

How we chose these key lock boxes

• We worked from the Amazon Australia product pages and kept only boxes whose listing gave us real numbers to compare: body dimensions, key capacity, material and a stated water resistance level, or an honest blank where there was none.
• Star ratings, review counts and prices were all checked fresh on the day this guide was written, so the comparisons come from one snapshot rather than a mix of old figures.
• We favoured a resettable code over a fixed one, because the point of a key safe is handing access to a cleaner or a tradie and taking it back later.
• We take no product samples and we ignore seller badges. Where a listing makes a security claim we cannot trace to a certifying body, we leave it out rather than repeat it.

Best key lock box overall: Master Lock 5401D Wall Mount

The 5401D is the box we would put on our own wall, and the reason is boring competence rather than any headline feature. It is a wall mounted unit measuring 38 by 83 by 120 mm with an alloy steel body, a set your own resettable combination and room for five keys, and the mounting hardware comes in the box. The listing rates it weather resistant with an anti corrosion finish, which is the specification that matters near the coast, where salt in the air chews through cheap plated metal faster than rain does.

At 227 g it is the lightest of our seven picks, which is genuinely useful during installation: a heavier box sags off the fixings while you mark the second hole, and up a ladder that weight difference turns a two person job back into a five minute one.

Five keys is the right capacity for a house rather than a portfolio, and the chamber does not swallow them so deeply that you are fishing in the dark. The dials are standard style rather than a push button pad, so there are no batteries to go flat and no contacts to corrode over a wet winter.

It carries 4.6 stars from 6,525 ratings. For a first home where you want one spare key reachable by the people you trust and nobody else, buy this and stop thinking about it.

Flaws but not dealbreakers

Weather resistant is not the same word as waterproof, and the listing stops short of a waterproof rating. If your only mounting spot is fully exposed to driving rain, one of the boxes here claiming a waterproof rating is safer. Five keys is a hard ceiling, so if you carry a bulky car fob look at the Iron Lock instead.

Best portable key safe for renters: Master Lock 5400D

The 5400D solves the problem that stops most renters buying a key safe at all: you are not allowed to drill into the wall. It hangs over a door knob, gate rail or fence bracket on a shackle, so it goes up in seconds and comes down with you when the lease ends. The body is 83 mm of metal measuring 38 by 83 by 159 mm, it weighs 454 g, and it takes a set your own four digit code.

Two details lift it above the generic shackle boxes. The first is the weather shutter, a sliding cover over the dials when the box is closed, which on an exposed porch is the difference between dials that still turn smoothly in year three and dials that need a shove. The second is the limited lifetime warranty on the listing.

It is also the most reviewed pick in this guide, with 24,222 ratings at 4.6 stars, many times the review volume of anything else here. A product with that much feedback has had every failure mode reported, and the score has held up.

The trade off is that a hanging box can be lifted off if the shackle is cut or the handle comes apart, which is why we still recommend a wall mounted box to anyone who owns the place. But it beats a key under the pot plant, and it is our first choice for a rental.

Flaws but not dealbreakers

The listing calls it weather resistant rather than waterproof, same as the 5401D. At 454 g it knocks against a door every time the door moves, so on a lightweight security screen expect rattle unless you pad it.

Best budget key lock box: Fayleeko LBWH-802

This is the cheapest of our seven picks and it does not compromise on the two specifications that matter most outdoors. Its listing carries a waterproof water resistance level, which five of the seven do not, and it can be wall mounted with the supplied screws or hung from a shackle, so it works whether you own or rent.

At 40 by 85 by 180 mm it is the tallest body of our picks on the listed dimensions, and a taller chamber is easier to drop a bunch of keys into and pull them back out of. The listing also flags clearly visible keys, so you can see what is inside rather than groping blindly in the dark at the end of a shift. It weighs 567 g.

The score is the surprise: 4.6 stars from 5,742 ratings, level with our top two picks on rating and with a review sample in the same order of magnitude. At this price that is unusual, and it is why it earns a slot rather than a mention.

Flaws but not dealbreakers

Fayleeko is not a lock brand with decades behind it, so there is no long warranty story and no spare parts channel. Check the supplied fixings before mounting, because screws in this bracket are usually sized for masonry and will not hold in plasterboard or timber cladding. The body is also larger than the Master Lock boxes, so it is more visible on a wall.

Best heavy duty key box for landlords and agents: Master Lock 5415D

If a box will be opened by different people several times a week, buy for the mechanism rather than the sticker price. The 5415D is a zinc bodied wall mount measuring 13.2 by 10.5 by 4.3 cm that weighs 1.36 kg, making it the heaviest of our picks, and it holds five keys. It carries a limited lifetime warranty on the listing and Master Lock aims it squarely at landlords and agents.

Mass is not a gimmick here. A heavier zinc casting resists the two things that kill a key box in service: deformation from someone yanking a stuck key ring out at an angle, and flex around the fixing points when a box is opened hundreds of times a year. The lighter boxes here suit a household that opens one a fortnight, not an investment property a cleaning crew visits weekly.

The rating sits at 4.5 stars from 848 ratings, a smaller sample than the top two picks but large enough to trust, and consistent with the rest of the Master Lock range here.

Flaws but not dealbreakers

The listing calls it an outdoor mounted box but publishes no water resistance level, a strange gap on a product built for exterior use, so choose a sheltered position. It is the heaviest of our picks, so the fixings and wall material need to be right. And a household that opens a key safe once a fortnight is buying durability it will never consume.

Best big capacity key lock box: Iron Lock XXL Wall Mount

Modern car keys ruined a lot of key safes. A proximity fob with a plastic head is two or three times the bulk of a cut brass key, so adding one to a five key box leaves you a four key box that no longer closes cleanly. The Iron Lock XXL exists for that problem, with a stated internal capacity of 21.33 cubic inches, roughly 350 cubic centimetres, the largest figure among the picks here whose listings publish one.

The body measures 5.3 by 10.4 by 14.5 cm in aluminium and zinc, weighs 740 g, and the listing rates it waterproof. It uses a four digit resettable code with an A and B switch, and arrives with four screws, four anchors and a key hanger so keys sit on a hook rather than pooling at the bottom. That hanger makes a large chamber usable instead of just big.

It is the highest rated pick in this guide at 4.7 stars from 921 ratings, and the dearest of our picks. Whether that premium is worth paying comes down to one question: does a car key or a fob need to live in this box? If yes, the extra room removes a daily irritation. If you only ever need one house key in there, the smaller Master Lock boxes are the better buy.

Flaws but not dealbreakers

A larger box is a more conspicuous box, and the value of a key safe depends partly on nobody noticing it, so choose a position out of sight from the street. Iron Lock is a smaller brand than Master Lock or Kidde, so parts and long term support are a thin story. And at 740 g on the wall you want proper masonry anchors, not the plastic plugs from the kitchen drawer.

Best key lock box for hanging on a door handle: Kingsley Guard-a-Key K200

The Guard-a-Key K200 is the box you have seen on the front door of every listed property in the country. It is a compact portable unit measuring 6 by 6 by 13.5 cm with a 10 cubic inch chamber, a mechanical code lock and a shackle, weighing only 268 g. It ships with a vinyl cover that sits between the shackle and the door so the box does not chew the paint off a freshly finished front door.

That cover is why we included it over other shackle boxes. If you are selling, styling or letting a property, a metal shackle rubbing a painted timber door through six weeks of open homes leaves marks that cost real money to fix. Nobody else here ships that piece of vinyl in the box.

It sits at 4.6 stars from 7,825 ratings, the second largest review sample in this guide, reflecting how many are in circulation through the real estate trade. The mechanical code lock means no batteries and no electronics, and the compact body hangs neatly without swinging the way a heavier box does.

Flaws but not dealbreakers

The listing states it is not water resistant, a real limitation outdoors in an Australian climate. Treat it as a temporary or sheltered solution rather than a set and forget wall fixture. The 10 cubic inch chamber is small, so a chunky car fob will not sit comfortably, and the vinyl cover is a consumable that eventually perishes in UV.

Best key safe with an Australian supplier behind it: Kidde KeySafe Original

The Kidde KeySafe Original is the model Australian locksmiths have been fitting for decades, and it is the only pick in this guide whose listing names an Australian company as the manufacturer, Kidde Australia Pty Ltd. That matters less for the metal and more for the paperwork: a local entity means a local warranty conversation rather than an international one.

Mechanically it is a permanent wall mount in a titanium finish measuring 6.4 by 5.6 by 10.9 cm, weighing 658 g, with a metal body, a mechanical code lock and push button control rather than dials. You press a set of buttons in any order, then slide the release. That is faster one handed in the rain than a dial and easier for someone with limited grip strength. It holds five keys and the code resets without tools.

The listing frames it for family, cleaners and agents across homes, rentals and holiday properties, an accurate description of who buys it. It sits at 4.5 stars, though from only 47 ratings, the smallest review sample in this guide. That is not a red flag on a design this old and this widely fitted, but the score carries less weight than the 5401D or the 5400D, which is why it sits here rather than at the top.

Flaws but not dealbreakers

The listing states it is not water resistant, so a sheltered position under an eave or porch roof is important rather than optional. And the push button mechanism gives away nothing about how many digits are in the code, which some find reassuring and others find confusing when handing instructions to a cleaner over the phone.

Which key lock box should you buy?

Find the row that matches your situation.

What should you look for in a key lock box?

Mounting method. Wall mounted boxes bolt to masonry and cannot simply be lifted off. Shackle boxes hang over a knob, rail or bracket and can. If you own the property, mount it. If you rent, hang it on a solid handle rather than a screen door. This choice decides more about security than the brand on the front.

Fixings and wall type. Most Australian homes are brick veneer, so the outer skin is real brick and the inner frame is timber. Mount into the brick with masonry anchors rated for the weight. On weatherboard, fibre cement or render over foam, find a stud or use a fixing rated for that substrate, because a box torn out of soft cladding takes a chunk of wall with it.

A stated water resistance level. This is where most key lock box listings go quiet. Of our seven picks, two state waterproof, two state weather resistant, two state not water resistant and one gives no level. Anything on an exposed wall in Queensland or on a coastal boundary should be in the first group or under an eave.

Real internal room. Measure the actual bunch of keys you intend to store, including any car fob, before you buy. A five key rating assumes five flat brass keys, and one proximity fob eats the space of two or three. A box that will not close properly lets water in.

A code you can reset yourself. Check the listing says the combination is resettable rather than fixed at the factory, then change it when a cleaner leaves, when a tenancy ends, when a tradie finishes, and once a year regardless. A code you have never changed is not much better than a key under the mat.

One thing worth saying plainly: a key lock box is a deterrent, not a vault. If what you want to protect is documents, cash or jewellery, that is a different product and you should read our guide to the best home safes in Australia instead. If you would rather remove physical keys altogether, a smart lock solves a different version of the same problem, with a battery to think about.

How do you look after a key lock box outdoors?

A little maintenance is the difference between a box that opens smoothly in year five and one you end up cutting off the wall.

Work the dials or buttons through their full range every couple of months even if nobody has needed the key, because mechanisms that sit still in salt air or dust seize gradually rather than suddenly. If a dial feels gritty, use a dry lubricant, because household oil attracts dust and makes it worse.

Check the fixings once a year. Thermal movement, a slamming security door and people pulling on the box will loosen a screw eventually, and a loose box flexes and lets water in around the seams. Rinse the body with fresh water if you are within a few kilometres of surf, because salt is the main enemy of cast and plated metal in Australia.

What else did we consider?

Several boxes came close, and the reasons will steer you away from the same traps.

The ABUS KeyGarage 767 is a well built wall mounted box from a serious European lock brand, and on paper it belongs here. It came out with the lowest star rating of everything we looked at closely, and when a strong brand scores below the generic competition, that gap usually says something about the model rather than the badge.

The Master Lock 5441EC adds Bluetooth so you can open the box from a phone. We left it out on principle rather than quality: a key safe is what you fall back on when the normal way in has failed, and adding a battery and a phone pairing to your fallback is a strange trade.

Magnetic under car key holders keep appearing in these search results and they are not key lock boxes. No code, no lock, no barrier: anyone who runs a hand under the wheel arch has your key. We also set a floor for how much customer feedback a product needs before we will recommend it, which ruled out several very cheap boxes carrying single digit review counts.

Key lock box questions, answered

Are key lock boxes safe to use in Australia?

A key lock box is a deterrent rather than a vault, and it is safer than the habit it replaces. A key under a mat, in a pot or on the meter box sits in the first three places anyone looks. A coded box makes access something you can grant and revoke, so change the code whenever a cleaner, tenant or tradie no longer needs it, mount it out of sight from the street rather than beside the front door, and keep anything genuinely valuable in a proper safe.

What key safes do police recommend?

We could not confirm an Australian police program that endorses specific key safes, and none of the listings for our seven picks states a security certification of any kind. Certification labels do circulate in key safe marketing, mostly from overseas schemes, so if a seller quotes one, ask which body issued it and check the certificate at the source before paying a premium. Judge the box on its mounting method, body material and weather rating instead.

Should you wall mount a key safe or use a portable one?

Wall mount it if you own the property, because a bolted box cannot simply be lifted off and carried away to be opened somewhere quiet. Use a portable shackle box if you rent, if you need to move it between a house and a holiday place, or if you only need it for a few weeks of open homes. A portable box on a solid handle still beats a hidden key, but it is the weaker of the two arrangements.

Where is the best place to put a key lock box outside?

Somewhere sheltered, out of sight from the footpath, and not immediately beside the door it opens. A side wall, a porch return, a spot under an eave or the wall behind a gate all beat the front elevation, because a box nobody notices is a box nobody attacks. Shelter matters as much as concealment: of our seven picks, two listings state the box is not water resistant and one gives no level at all.

How many keys does a key lock box hold?

Most household boxes are rated for five keys, including the Master Lock 5401D, the Master Lock 5415D and the Kidde KeySafe Original here. That rating assumes five flat cut keys, so one modern car fob can take the room of two or three. If you need to store a fob, the Iron Lock XXL states the largest internal capacity of the picks whose listings publish one, at 21.33 cubic inches or roughly 350 cubic centimetres.
