Other locksmith services in Camden need lock changes, repairs, upgrades or commercial help instead?
All services in Camden →On Victorian and Edwardian terrace doors the existing key hardware often includes original Chubb or Yale period mortice cases with non-BS3621 lever counts. Where the brief is to upgrade to an insurance-compliant spec, we identify the existing case type on arrival and confirm which replacement will seat in the same aperture without alteration — minimising timber disruption on a door that may be over a century old.
On the day
Fitting day in Camden — 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 Camden 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 Camden 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 NW1 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 assess the glazed panel proximity to the lock 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 double-cylinder option 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 Camden
Glazed panel proximity assessment: if the nearest glass panel is within 400 mm of the nightlatch thumb-turn, assess whether a double-cylinder is appropriate. Document the decision either way on the job sheet.
-
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
Camden stock varies widely. Frame material dictates fixings, strike plate type, and the correct spec for the double-cylinder option.
- Victorian terrace front doors with a glazed panel within arm's reach of the thumb-turn present an inside-attack risk — a double-cylinder nightlatch removes the thumb-turn, requiring a key on the inside.
- Double-cylinder nightlatches are only appropriate where the door can be exited quickly by other means — confirm the fire-escape route is clear before fitting.
- Letter plate proximity to the lock: if the letter plate slot is within 400 mm of the latch, a letter plate restrictor or cage should be considered as part of the security scope.
Pricing — what shifts it
What affects a Camden lock installation price
Timber condition on a Victorian terrace front door is the most variable pricing factor: a door in sound condition with a clean existing mortice fits quickly, while one with rot at the lock rail or a split stile face needs remedial work before the lock can be secured properly. Condition is assessed on arrival and any prep work is costed and approved before it is carried out. 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 Camden 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 Camden.
Lock Installation in Camden — FAQ
Common questions about lock installation in Camden.
Can you install a lock on a brand-new door?
Period timber doors have their own sizing constraints: rebate depth and stile width are the primary fitting variables, and the answer to most installation questions starts there rather than with the lock model. Yes — this is one of our most common installation jobs in Camden. 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.
Do I need BS3621 on a new installation?
For external doors on Camden homes with standard insurance — yes, almost certainly. BS3621 is the minimum most UK home insurers specify on final-exit wooden doors. We fit BS3621 as standard and issue written paperwork confirming the standard for your insurance file.
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.
We've just moved into a new-build in Camden — do the locks already meet insurance standards?
Not always. Many Camden new-builds come with entry-level euro cylinders on UPVC or composite doors that lack the TS007 3-star anti-snap rating, and sometimes a mortice case that predates BS3621 on the side door. We survey the whole property, identify any hardware gaps, and upgrade to compliant standards on the same visit — with a compliance pack for your insurer.
