All services in Cambridge →Local context
Most emergency lockouts in Cambridge involve nightlatches on Victorian terraced houses — the spring-latch mechanism means the door closes fully with keys on the inside, which accounts for a large share of our local callout volume. UPVC doors with multipoint mechanisms create a different pattern: if the handle isn't fully lifted when closing, the hooks don't engage and the cylinder won't operate from outside.
A recurring thread on local callouts is worn mortice locks on Victorian and Edwardian properties requiring servicing or replacement — cylinders that have been in service for 15+ years fail at the worst moment: under the stress of a rushed exit or after the first cold snap. We stock replacement cylinders for the most common local hardware profiles, so when a worn mechanism finally fails mid-lockout, there's no second trip.
How it works
We ask for the property type, whether the door is UPVC, composite, or timber, and whether any keys are broken or missing. This tells us what hardware to carry and whether proof of address will be needed on arrival.
The closest available engineer is routed to you — typically within 28 minutes across Cambridge. You get the engineer's name and arrival time via text.
Before touching the lock, the engineer confirms the fastest non-destructive method and locks in a fixed price. No work starts until you agree.
Non-destructive picking wherever possible. If drilling is required, the cylinder is replaced on site and new keys issued before we leave. Payment on completion with a written invoice.
Situations we handle
The most common callout in Cambridge — door pulled shut with keys inside. On Victorian terraced houses, the lock is usually a Yale-style nightlatch with a deadlocking function. Non-destructive picking typically resolves these without affecting the door or mechanism.
Our approach Non-destructive entry first; cylinder or nightlatch replacement on site only if the mechanism is already damaged.
Typical on older cylinders where the key has worn thin over years of use. We extract the broken half with specialist tools, test the lock, and either service or replace the cylinder depending on condition. We see Yale lock failures in student HMOs needing urgent out-of-hours response often as an underlying cause in Cambridge.
Our approach Extraction first; cylinder replacement if the mechanism is compromised — new keys cut on site.
Purpose-built blocks across Cambridge often have a fob or keypad entry for the main door and individual locks per flat. When the main system fails or a flat door won't release, we diagnose on site and either fix the individual lock or flag the communal issue to the freeholder/managing agent.
Our approach Resolve the individual flat access first; advise on the communal fault and coordinate with the block manager if needed.
Patterns like these shape the first question on every Cambridge callout: can we prove you live there? — which is what the checklist below covers.

Primary — any one of these

We ask because in most genuine callouts in Cambridge, proof is somewhere on the customer — and it protects you against anyone else using the same route in.
Entry methods
The picking-vs-drilling decision, door by door
Non-destructive picking is the default on every callout, regardless of time of day or lock age. The technique works on the vast majority of Yale nightlatches and euro cylinders without leaving any trace of entry. Drilling is a last resort — used only when the mechanism is already seized, snapped, or physically obstructed.
A timber door with a nightlatch is a different problem from a UPVC with a multipoint. On nightlatches, the spring latch can often be manipulated directly. On UPVC multipoints, the cylinder is picked in isolation — but only after checking whether a misaligned door or un-lifted handle is the real cause of the fault.
Some cylinders — anti-snap 3-star, Mul-T-Lock, ASSA, high-security restricted keys — are designed to resist picking. If drilling is unavoidable, the engineer removes only the cylinder, not the door or lock case. A replacement cylinder is fitted on site before we leave, so the door stays secure when we do.
Before any lockout work in Cambridge, we ask for proof you have the right to enter: a utility bill, tenancy agreement, driving licence showing the address, or confirmation from a landlord or letting agent. This protects you from future key-holders using the callout as a pretext, and protects us from facilitating unauthorised entry.
Victorian terraces in Petersfield and Romsey subdivided into student HMOs carry 3-lever bedroom locks plus multi-keyed front-door nightlatches with heavy seasonal turnover

Common questions about emergency lockout in Cambridge.
In most Cambridge callouts, yes — non-destructive picking is our default method and resolves most lockouts without affecting the door, frame, or lock. Drilling is a last resort, used only when the mechanism is already compromised or a specialist high-security cylinder resists picking. If drilling is required, the cylinder is replaced on site before we leave.
Often, yes. If the issue is with your individual flat door, we fix that on site. If the fault is with the main communal entry (keypad, fob reader, electric release), we can diagnose and in many cases repair, but some blocks have maintenance contracts that require a specific contractor — we'll advise you on site and talk to the managing agent if needed.
Yes — before any emergency lockout work in Cambridge, we ask for proof that you have a right to enter the property. A recent utility bill, tenancy agreement, ID with the address, or confirmation from a named landlord or letting agent all work. This protects you as much as it protects us.
Regularly — much of our Cambridge emergency lockout work involves tenants locked out of rented properties. We accept authorisation by phone or email from a named landlord or letting agent and provide a written invoice afterwards. Sensible checks apply — we confirm the caller matches the registered tenant.
Yes — that's the policy. If drilling is the only option, the cylinder is replaced on site with a like-for-like anti-snap equivalent before we leave, so the door is secured on the same visit. New keys are cut on site and the old cylinder's contents are rendered unusable.
Yes — HMOs and student lets are a regular part of our Cambridge lockout work. We apply the same proof-of-address rules: a tenancy agreement, student ID with the address, or authorisation from the landlord or letting agent all work. We're familiar with the shared-house dynamic — multiple tenants, sometimes unclear who holds the key.
