Other locksmith services in Leicester need lock changes, repairs, upgrades or commercial help instead?
All services in Leicester →Converted multi-occupancy houses often contain several generations of doors under one roof: an original timber front door, internal partition doors of varying leaf thickness, and fire-rated corridor doors on newer conversions. Each type has different fitting requirements — mortice dimensions on the timber front door, consistent backsets on the internal room doors, and intumescent-seal clearance on fire doors. We identify each door type on arrival before specifying any cylinder, so the quote matches the actual access-point inventory.
On the day
Fitting day in Leicester — the five-step sequence
New locks go in against a defined sequence, not ad-hoc. Here's the order each of our engineers works through on a typical Leicester installation — the same on a terraced front door as on a new-build UPVC back door.
- 01
Confirm parts and measurements
Before any tools come out we walk through the hardware that's been ordered for your Leicester property — cylinder sizes, gearbox type where relevant, strike plate dimensions, and any fire or insurance ratings. If something's a size off, we reschedule rather than force the fit.
- 02
Prep door and frame
Existing furniture is removed, the door checked for square and for any swelling or drop on the hinges. On older LE1 stock the frame often needs a chisel adjustment at the keep; on new-build doors it's usually a clean lift and drop. Anything structural that's out of scope is flagged before we go further.
- 03
Fit the hardware
Cylinder, gearbox, multipoint strip, or mortice case goes in against the manufacturer's template. Fixings match the frame material — steel screws into softwood, self-tappers into aluminium, no-slip fixings into composite. Nothing is over-torqued; we measure the internal door leaf before any fixing is committed to final torque.
- 04
Align and test
Every operation is tested with the door both open and closed — key in, key out, handle lifted, deadlock thrown, thumb-turn from inside. On a multipoint we test each hook and shoot-bolt independently before signing off. Anything that binds gets adjusted there and then, not "later".
- 05
Handover and keys
Keys are counted against the job card and handed over with a one-page written summary: what was fitted, the internal door cylinder spec noted, serial numbers where relevant, and a seven-day follow-up window. On insurance-graded installs the compliance paperwork lands by email the same day.
What we measure
Four measurements that decide the fit in Leicester
HMO multi-room installation: measure door leaf thickness and backset per room door — internal doors typically run 30/30 or 35/35 cylinders, smaller than the front door. Check cam engagement under load on each door before handing back keys.
-
Door thickness
44 / 54 / 70 mm
Determines whether the standard cylinder length fits flush or needs a long-body variant.
-
Backset
45 / 60 / 70 mm
Distance from the edge of the door to the centre of the cylinder. Common on UK doors but not universal.
-
Euro cylinder length
30/30 → 45/55
Measured separately from each side of the door. Must sit flush — too proud and the cylinder is vulnerable to snapping.
-
Frame material
Timber · Composite · Aluminium
Leicester stock varies widely. Frame material dictates fixings, strike plate type, and the correct spec for the internal door cylinder.
- Internal HMO room doors are typically lighter than front doors and run a smaller cylinder — measure the leaf thickness per door, not per property.
- Cylinder cam engagement on internal doors must be checked under load; light door construction means the cam can move under repeated key use if the cylinder is oversized.
- On a multi-room property, test each cylinder independently before signing off — a cylinder that passes open-door test may bind on the closed door under frame pressure.
Pricing — what shifts it
What affects a Leicester lock installation price
Doing all rooms in a single visit is more cost-effective than returning for individual doors as each comes up. The labour saving across a whole property is usually enough to offset the parts cost difference between a restricted scheme and individual cylinders. We quote both so the numbers are visible before any decision is made. From £59.
- 01
New-fit vs like-for-like replacement
Fitting into an existing cut-out is cheaper than routing a new one. Period doors in Leicester often need a fresh cut; UPVC is almost always like-for-like.
- 02
Hardware tier
Standard cylinder sits at the base price; TS007 3-star anti-snap, BS3621 mortice, and restricted keyways each add to the parts cost.
- 03
Door condition
A square door on tight hinges fits fast. Drop at the hinge side, swelling, or a warped strike plate adds time — we flag this during the measurement call, not at the end.
- 04
Number of doors on the same visit
Fitting front, back, and garage side-door in one appointment is meaningfully cheaper than three separate visits across Leicester.
Lock Installation in Leicester — FAQ
Common questions about lock installation in Leicester.
Can you install a lock on a brand-new door?
For HMO and student properties the installation question is usually about per-room cylinder economics: rekey versus replace on each tenancy change, and whether a restricted keyway is worth the additional cost per door. Yes — this is one of our most common installation jobs in Leicester. Carpenters and joiners often hang the door and leave lock fitting to specialists. We measure the rebate, chisel for a BS3621 mortice case, fit the strike plate, and test through a full key cycle. Finished work looks factory-fit.
Can you keyed-alike multiple new locks?
Yes — if you want one key to open your front and rear doors, we supply keyed-alike cylinders on the most common profiles. Arrange at the survey stage so we bring matching parts. This works cleanly on UPVC euro cylinders and on certain mortice profiles.
Do you install locks on gates and outbuildings?
Yes — weather-rated padlocks, BS-grade hasps, garden gate locks, and shed/garage door hardware are all regular installation work across Leicester. We match the lock to the exposure (weatherproofing matters outdoors) and fit on the same visit.
Will a new lock invalidate my door warranty?
Not normally. Most door manufacturers specify that lock installations must be done by a competent locksmith — we are, and we fit to manufacturer-approved positions and dimensions. If in doubt, mention the door brand when you call and we'll confirm compatibility before attending.
