Commercial Lock Change

Every time an employee leaves — whether the departure is planned or not — any keys they held become a security liability. This is true even if you believe the keys were handed back, because copies can be made without your knowledge. A proper commercial lock change replaces the cylinder or the entire lock mechanism, so previous keys simply will not work. This is the only dependable way to restore access control after a staff change, a contractor engagement, or a tenancy handover. Upgrading the lock at the same time — moving from a basic euro cylinder to an anti-snap, anti-pick, anti-drill cylinder rated to TS007 3-star, for example — means you are not just solving the immediate problem but also hardening the door against the most common forced-entry methods used against commercial premises.

Beyond staff changes, businesses often approach us after a break-in attempt, after moving into a unit with unknown lock history, or simply because an insurer has flagged that the existing hardware does not meet their requirements. Insurance policies for commercial properties frequently specify a minimum standard, such as a 5-lever mortice deadlock to BS3621 on timber-framed doors, or an anti-snap cylinder on uPVC and composite doors. Our technicians can assess what you currently have, advise on what your policy is likely to require, and carry out the work in a single visit.

Our commercial locksmith service covers a wide range of door and lock types. We work on timber-framed office doors with traditional 5-lever mortice deadlocks, uPVC doors with multipoint locking systems, aluminium-framed shopfronts, fire doors, and communal entrance doors in office buildings and mixed-use blocks. Where the existing lock or frame has sustained damage — from a previous break-in, a forced entry, or simple wear — we can repair or replace the affected components and, wherever the door condition allows, we work carefully to avoid unnecessary damage to frames or surrounding surfaces.

For a standard door lock change on a uPVC or composite commercial door, we replace the euro cylinder with a high-security equivalent that resists snapping — a method burglars frequently use to defeat standard cylinders in seconds. For timber doors with mortice locks, we can upgrade to a BS3621-compliant 5-lever mortice deadlock and, where appropriate, fit a heavy-duty nightlatch above it. If you manage multiple units or have a premises with several access points, we can work through every door in a single visit, issuing a fresh set of matched keys so your team carries fewer separate keys. Call 020 3757 5826 and we will talk through what your premises needs before we set off.

Businesses in Camberwell that have experienced a break-in, or that have just dismissed a member of staff with site access, need a lock change service that responds at any hour. Our 24/7 availability means you are not left with a compromised door overnight or over a weekend. We send a technician straight away and are typically on site in around 30 minutes. Because we are a fully mobile commercial locksmith, there is no depot to return to and no job queue at a fixed workshop — the technician comes to you with a fully stocked vehicle.

When you call us after a break-in, our technician will first assess whether the door and frame are structurally sound enough to accept a new lock, or whether temporary boarding is needed alongside the lock change. We will also note whether the existing hardware contributed to the compromise — for example, a standard cylinder that snapped cleanly — and recommend a direct upgrade so the same vulnerability is closed permanently. All of this is explained clearly on site, and no additional work is carried out without your agreement and a confirmed price.

We do not publish fixed price lists because the right answer depends on what is actually on your door. The factors that shape the final quote include the type and number of locks being changed, the grade of replacement hardware you choose, whether any remedial work to the frame or door is needed, the time of day or night you call, and the travel distance from our technician's current location to your premises. Weekend and bank holiday call-outs, and work carried out in the early hours, reflect the operational costs of genuine 24/7 availability. Every one of these factors is taken into account when we give you a price on the phone — before the technician sets off and before any work begins. There are no additional charges added at the end of the job.

If you are comparing quotes for a planned commercial lock installation rather than an emergency, we are happy to discuss the job in detail over the phone on 020 3757 5826 so you can make an informed decision. We will explain exactly which locks we recommend and why, what hardware brands and ratings are involved, and what the work will entail on the day.
