What you are actually buying

A key safe is only as good as the brick it is bolted to

Strip away the marketing and a key safe is three things: a steel or zinc-alloy body, a combination dial that resets in 30 seconds, and four anchor bolts that transfer load into masonry. That last part is the piece everyone gets wrong — a heavy-duty safe fitted into mortar will fail the same way a £15 Amazon safe will, in under a minute with a mole grip.

We fit key safes across South London the same way we fit locks: survey the wall first, verify it's solid brick or dense concrete, drill into the brick face (never the mortar line), and plug the holes with the correct-size sleeve anchor for the unit. The safe itself is a 5-minute bolt-on. The hour of thought goes into where and how.

Most clients fall into one of four groups: landlords and Airbnb hosts who need a code they can change between tenants, carers and family members of an elderly resident who cannot get to the door quickly, cleaners and dog walkers who need keys during the day without cutting spares, and busy households that are tired of hiding a key under a plant pot. Every reason is valid; the safe needs to match.

Labour is £150 for a standard brick-wall fit during working hours, including the fixing pack, code reset and a printed spec sheet for your insurer. Key safes we supply start at around £40 for a basic compliant mechanical unit and top out at £180 for a high-spec Supra C500 Pro. See our services overview or commercial locksmith page if you manage a portfolio of properties.

Dulwich Estate properties in West Dulwich and Crystal Palace Park-edge mansion blocks often need a brick-mounted key safe in a discreet position — Bromley and Lambeth consent rules vary, we coordinate where needed. (Pre-booked: West Dulwich · Crystal Palace.)

Who actually needs one

Six households we fit key safes for every week

If one of these sounds like you, a properly specified key safe solves the problem without hiding a key outside.

Landlords & letting agents

Change the code in 60 seconds when a tenant moves out. No re-keying, no spare-key pickups, no lockouts. One safe covers every tenancy turnover.

Airbnb & holiday-let hosts

Guest check-in without handover. Change the code per booking, share via the platform's messaging. No lost keys, no lockbox dangling from a drainpipe.

Carers & family of elderly residents

Mum cannot get to the door in 30 seconds any more. Carer enters the code and is inside without drilling ringers awake. NHS and social services recognise this.

Cleaners & dog walkers

Thursday 9 am cleaning slot, Wednesday 2 pm dog walk. Shared code for each trade, changed quarterly. No permanent spare keys circulating.

Busy commuter households

Kids home from school before parents. Parcel needs a hidden key. End of the “key under the plant pot” era — the first thing a burglar checks.

Small offices & retail

Morning opener, evening closer, weekend stock delivery. Shared code + per-person shift log beats handing out spare keys that never come back.

Your fit, step by step

Four steps, 20–30 minutes, fixed price

Here's exactly how we fit every key safe — photographed from a recent install in Croydon.

01 ~5 min Hammer drill creating fixing holes for key safe installation in solid brick

Drill into solid brick, not mortar

Position marked at chest height on a solid brick face (not the mortar line). SDS hammer drill with a 6 or 8 mm masonry bit, four holes pre-measured to match the safe's backplate. We drill to the exact depth the anchor bolts need — no deeper, no shallower.

Brick face · not mortarSDS hammer drill
02 ~8 min Key safe interior being fixed into brickwork with heavy-duty anchor screws

Bolt the backplate, torque the fixings

Plastic sleeve plugs tapped into each hole, the steel backplate offered up and manufacturer's own anchor bolts driven in with an impact driver. Torqued until the plate sits flush against the brick face — no flex, no gap. This step is the one that holds the safe against a 400 kg+ pull.

Manufacturer anchorsTorque to spec
03 ~5 min Locksmith setting the combination code on a newly installed key safe

Set your combination — you choose

Default factory code cleared. You pick a 4-digit combination that is not your door number, postcode or birth year. Code reset mechanism exercised 3 times to confirm it works smoothly. Spare tumbler-reset tool left with you for the next rotation.

04 ~5 min Finished key safe fitted to brick wall at front of a South London home

Test, seal & hand over

Key loaded inside, code tested 5 times lock-and-unlock. Weather seal around the backplate. Printed spec sheet with model, fit date, substrate note, your new code (sealed envelope) — for your insurer and for safe-keeping. 12-month workmanship warranty.

Insurer spec sheet12-mo warranty
What actually makes a key safe secure

Two things decide a key safe's security — the body and the wall

Plenty of marketing language gets attached to key safes. Fewer people know what actually matters when one is being attacked on a doorstep. Here is the short version — and why the substrate matters as much as the body.

Body and build quality

  • Heavy-duty

    Heavy-duty solid steel body. Reinforced backplate, manufacturer-spec anchor bolts, full attack-tested supply chain (Supra, Burton, Keyguard). Resists over 400 kg pull-out and standard attack tools for 60+ seconds. The only tier we fit on a front elevation.

  • Insurance-friendly

    The heavy-duty bodies we stock are the insurance-friendly models most UK insurers expect to see for external door-key storage. We supply a written spec sheet with the make and model for your insurer file.

  • CE only

    Means very little. CE marking is a self-declaration, not a security test. Plenty of £15 marketplace safes carry a CE sticker and fail in under a minute.

  • Uncertified

    No rating, no test, no insurer will honour a claim that relies on one. Avoid for external fits. OK for inside a garage for spare keys only.

Substrate matters — what we drill into

  • Good

    Solid brick or dense concrete. Most South London terraces have this. Hits the manufacturer's 400 kg+ pull-out spec — the safe behaves as advertised.

  • Caution

    Concrete render over block. Looks solid, often isn't. We sound-test with a chisel handle before drilling and move if the render sits over breeze or insulation.

  • Caution

    Aerated / lightweight block. Used in modern extensions. Needs chemical anchors or a steel backplate to spread the load — quotable extra, we tell you on survey.

  • No

    Mortar joints. Looks easier because they are softer. Fails every pull-out test. We never fit into mortar even when the customer asks us to.

Wrong substrate = wrong safe. No amount of body weight compensates for a bad fix. Our survey catches this before you pay for the safe.

Why people choose us

Six things cheap key safe fitters skip

  • Substrate test before drilling.We sound-test the brick with a chisel handle. Soft render or breeze block = we move the position. No bodged mortar fixings.
  • Heavy-duty bodies only on fronts.Insurance-friendly heavy-duty bodies for any external fit. We keep cheaper models for internal garage use only.
  • Manufacturer's anchor bolts.Not the "close enough" screws from the van. Each brand specs its own anchor torque and length — we carry the right pack.
  • Placement checked for line-of-sight.Away from windows so tools cannot be leveraged. Out of direct street view so codes are not watched. We survey the whole elevation.
  • Code-reset training on-site.We walk you through rotating the code before we leave. Sealed envelope with initial code + reset tool stays with you, not in the paperwork drawer.
  • Spec sheet for your insurer.Model, make, fit date, substrate note, fit photos. Keeps your policy clean if you ever need to claim.

Three recent key safe customers — real names, real jobs

★ ★ ★ ★ ★

Mum moved in with us after hip surgery and needs a rota of carers visiting. Previous spare key hidden under a flower pot — awful, I know. Booked a key safe fit for the side return, technician arrived 30 minutes after the call, did a substrate test before drilling, fitted a Supra C500. Gave me one envelope with the code and a reset tool. Done in under 40 minutes including survey.

Six-bed HMO in Thornton Heath — tenants change every six months and I was paying a locksmith a rekey fee each time. Had a Keyguard XL fitted with a code I rotate between tenancies. ROI was about three turnovers. The fitter was straight with me about the wall: "the render here is soft, let's move the box one brick left where it is solid." Got a written cert for my insurer the same day.

Run two Airbnbs in Sutton and needed self-check-in that didn't involve me being there at midnight. Fitted a Burton Deep on each property, paired the codes to the platform message templates. Changes the code between guests take 30 seconds per property. Price was exactly what was quoted. Clean work — you'd think it came with the house.

Still not sure?

Questions we actually get asked

Short, honest answers from the team fitting these every week.

Do you supply the key safe or do I need to buy my own?
Either works. We carry heavy-duty insurance-friendly models on the van (Supra C500, Keyguard XL, Burton Deep) and can fit one on the same visit. If you have already bought a key safe, we fit it for the same £150 labour fee — we only refuse if it is a sub-standard unit that would put your home insurance at risk.
How long does a key safe installation take?
20 to 30 minutes for a standard brick-wall fit. Drilling four fixing holes with a hammer drill, plugging, bolting the backplate, screwing the unit on, and setting the code. We arrive with a masonry SDS drill, the right bits and a full fixing pack so there is no delay.
Are key safes actually secure?
A heavy-duty insurance-friendly key safe fitted into solid brick or concrete with the manufacturer's anchor bolts is rated as secure as your front door — it can resist over 400 kg of pull-out force and typical attack tools. A £15 marketplace key safe screwed into mortar will fail in under 60 seconds. The body weight and the substrate are what matter, not the box.
How much does a key safe cost to install?
Labour is £150 for a standard brick-wall fit during working hours. Key safes we supply range from around £40 for a basic model up to £180 for a heavy-duty Supra C500. The exact total depends on which model you choose — we quote the combined price in writing before any drilling. After-midnight fits are quoted individually.
Where should the key safe be fitted?
Into solid brick or dense concrete, away from windows and letterboxes, out of direct sightline from the street where possible, and at roughly chest height so an elderly user or carer does not need to reach. We survey the whole front elevation before drilling and recommend the position based on the brick you actually have — not the easiest spot to reach.
Will it invalidate my home insurance?
Only if the key safe is a sub-standard marketplace unit fitted into mortar. We only fit heavy-duty insurance-friendly models into solid brick or concrete, and we give you a written spec sheet with the make, model, fit date, substrate note and fit photos for your insurer's file. See our insurance-approved locks page for related standards.
Can tenants, carers or cleaners share the code?
Yes — that is the whole point. Every model we fit has a resettable combination. You can change the code in under a minute when a tenant leaves, a carer rotates off, or a guest checks out. We walk you through resetting it on handover and leave the tumbler-reset tool with you.
What if the wall is not solid brick?
We will tell you on survey. Breeze block, lightweight blockwork or soft render cannot hold a heavy-duty safe safely — we either find a solid section of brickwork nearby, fit a steel backplate to spread the load, or recommend a post-mounted model. We do not bodge mortar fixings to get the job done.
Not sure which safe or where to fit it? Send 2 photos on WhatsApp — the wall and the location — and we will tell you what fits and how much.
