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 Police Preferred 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 Police Preferred Supra C500 Pro. See our services overview or commercial locksmith page if you manage a portfolio of properties.
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.
Four steps, 20–30 minutes, fixed price
Here's exactly how we fit every key safe — photographed from a recent install in Croydon.
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.
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.
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.
Test, seal & hand over
Key loaded inside, code tested 5 times lock-and-unlock. Weather seal around the backplate. Printed spec sheet with LPCB cert number, fit date, model, your new code (sealed envelope) — for your insurer and for safe-keeping. 12-month workmanship warranty.
Two things decide a key safe's security — the rating and the wall
Everyone quotes "Police Preferred" and "LPS 1175". Fewer people know what either means. Here is the short version — and why the substrate matters as much as the badge.
Certification ratings
- A5 / SBD
Police Preferred (Secured by Design). LPS 1175 Issue 8 Security Rating 1 (SR1) minimum. Resists over 400 kg pull-out and standard attack tools for 60+ seconds. The only tier we fit on a front elevation.
- LPS 1175
The LPCB (Loss Prevention Certification Board) attack test. Issue 8 replaced older Issue 7 in 2019. Each unit has a certificate number you can verify on the LPCB Red Book database.
- 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.
Key safes fitted across 14+ South London postcodes
Van stock for same-day fits across all Croydon and Sutton postcodes, plus most of SW & SE. No travel surcharge within the M25 — one flat £150 labour fee.

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.
- Police Preferred models only on fronts.LPS 1175 A5 rated 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, LPCB cert number, fit date, substrate note. Keeps your policy clean if you ever need to claim.

- Free on-site survey with substrate test

Three ways to get a key safe fitted
Our £150 labour fee stays the same whichever path you pick. Pick the one that fits — you can bring your own safe or we supply one from van stock.

You've already bought a key safe. We check it's suitable, fit it into brick with manufacturer anchors, and set your code.
- Substrate test + position survey
- Drill, plug, anchor to brick only

- From £150 total — labour + safe
- Upgrade tiers available on-site
- Survey, fit, code set, weather seal
- Spec sheet on completion

Payment: card or cash. No hidden fees: the quote is the price. After midnight: prices increase — call for a quote. The £150 from-price assumes a standard brick-wall fit during working hours. Non-standard substrate, steel backplate fits, and multi-unit rollouts are quoted individually.

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.
