Commercial Lock Change

Staff turnover is the most common trigger. When an employee leaves — whether the departure was planned or abrupt — any key they held gives them ongoing physical access to your premises. Even if you recover the key on their last day, there is no way to verify it was not copied beforehand. The same risk applies when a cleaning contractor's contract ends, when a subtenant moves out, or when a managing agent changes hands. In each of these situations, a commercial lock change is not an overreaction; it is straightforward access control. Our technicians can carry out the work during business hours, in the evening, or over a weekend so that you do not lose trading time.

A second, less obvious trigger is wear and fatigue. Commercial doors take far more punishment than residential ones — delivery staff, customers, and colleagues all pass through multiple times a day. Cylinders wear, multipoint lock mechanisms become stiff, and euro cylinder profiles can become vulnerable to manipulation if the hardware is ageing. If a key is turning harder than it used to, or the lock occasionally fails to engage on the first attempt, that is an early warning worth acting on before it becomes a lockout. Call 01753 251949 and we can assess whether a repair or a full door lock change is the right course.

Slough's commercial stock is varied — Victorian terraces on Windsor Road converted into offices sit alongside modern uPVC-fronted retail units on the Queensmere precinct and steel-doored industrial units on the Slough Trading Estate. Our lock change service is not a one-size approach. For a traditional timber office door, we typically work with 5-lever mortice deadlocks (BS3621 where the insurer specifies it) alongside a nightlatch or rim lock on the same door. For uPVC and composite commercial doors — which are extremely common on Slough's newer retail and office developments — the focus is on the euro cylinder, and we fit anti-snap, anti-pick, anti-drill cylinders as standard because cylinder snapping remains a genuine method used by opportunist burglars in the area. For aluminium-framed entrance doors, we work with the specific profile required by the door system.

Beyond the cylinder itself, our commercial locksmith service also covers: fitting British Standard 5-lever mortice deadlocks, upgrading rim locks and nightlatches on secondary doors, replacing worn or damaged multipoint lock mechanisms on uPVC frames, fitting new door handles and escutcheons where the existing hardware is damaged, adjusting or replacing door closers that are causing misalignment, and advising on which lock grade is appropriate for your insurance schedule. We carry a wide range of commercial-grade parts on the van, so most jobs are completed in a single visit. Where a specialist part is needed, we tell you that before we start — and we confirm an exact up-front price before any work begins.

We do not publish fixed prices on this page because the variables genuinely matter. The type of lock and the number of doors involved are the biggest factors — replacing a single euro cylinder on a uPVC shopfront takes a different amount of time and parts than re-securing a six-door office suite with a mix of mortice deadlocks and rim cylinders. The time of day also plays a role: our 24/7 availability means we can attend at 2am if that is when you need us, but out-of-hours visits are priced differently to daytime appointments. Travel distance from our base in Slough is factored in, as is any specialist hardware required for non-standard door profiles.

What does not change is our process: when you call 01753 251949, we ask about the type of premises, the doors involved, and the lock types where you know them. From that conversation we give you a clear quote before we travel. There are no hidden additions when the work is done — the price agreed on the phone is the price on the invoice. We also carry out ownership or occupancy verification before carrying out any lock change, which is standard practice for a responsible commercial locksmith service and protects both you and us.

Not every lock change is planned. A door that will not lock at the end of the trading day, a cylinder that has seized after a suspected tampering attempt, or a lock that fails during a weekend shift — these situations cannot wait until Monday morning. As an emergency commercial locksmith operating across Slough and into the surrounding SL postcode districts, we are available every day of the year including bank holidays. When you call, we send a technician straight away and are usually with you in around 30 minutes, though travel time varies with traffic and distance.

Our mobile setup means the technician arrives with the tools and the most commonly needed commercial lock stock already on the van. For businesses on the Slough Trading Estate, in the town centre, or in areas like Cippenham and Langley, this translates to a genuinely fast response with no need to source parts separately. Where damage-free entry to the premises is needed first — for example, if the lock has seized before the change can take place — our trained technicians use methods that protect the door frame and surrounding hardware wherever that is possible. If you need us tonight, this weekend, or on a bank holiday, call 01753 251949 — we answer 24/7.
