Roller shutter lock mechanisms on post-war commercial estate units typically run alongside a keyed pedestrian door — the matrix covers the personnel door cylinder; call with the shutter type and we confirm the shutter hardware as a separate scope item.

Before we start

Who needs to authorise this work

Commercial locksmith work on any keyed access point requires on-site authority before it begins. This section confirms what we need from the Slough premises before the engineer arrives — not after.

  • The keyholder

    A named Lock case must be present or reachable by phone throughout the job. If the individual listed on the insurance schedule differs from the day-to-day keyholder, both names are needed before we can issue the compliance certificate.

  • What authority covers

    Authorisation must cover the full scope of work: cylinder changes, master-key scheme adjustments, and any access-control integration included in the quote. Verbal confirmation is noted on the job card — Estate commercial door stock is standard — compliance hardware fits without modification.

  • Delegated authority

    If the named keyholder cannot attend, they must assessed delegated authority in writing to the person on site. We accept email confirmation sent directly to the attending engineer before work begins.

On arrival

Access points: Slough premises inventory

We record each access point in scope before any hardware is touched. The list below covers the categories we check on a typical Slough commercial attendance — not all will apply to every premises.

  1. 01

    Main entrance

    We confirm the existing Anti-snap cylinder spec, test operation under load, and note the cylinder grade against the insurance schedule on arrival.

  2. 02

    Staff entrance

    Industrial units on post-war estates sometimes have a staff entrance that doubles as a secondary emergency egress point, meaning the lock specification must satisfy both the commercial insurer and the building's fire strategy. We note both requirements at survey and flag any conflict before installation begins.

  3. 03

    Goods bay / delivery access

    On post-war retail and warehouse units the goods-bay door frame is frequently steel, and corrosion at the keep or striker plate is a common finding on properties that have not had hardware maintenance in recent years. Frame integrity is confirmed before fitting a new lock, as a corroded keep will not provide the rated holding strength.

  4. 04

    Server room / data area

    High-security zone. BS3621 case spec confirmed against the risk assessment or insurance schedule rider before any work in this area proceeds.

  5. 05

    Fire door / emergency exit

    On post-war estate commercial properties fire-door function is checked on arrival as part of the access inventory even where the fire door is not in the declared work scope. A fire door that will not close and latch, or whose panic hardware operates only intermittently, is flagged on the job card and the keyholder is notified in writing before the engineer leaves.

Access point counts vary significantly across Slough commercial premises — a shopfront may have two points; a multi-floor office may have fifteen. Standard estate commercial doors accept van-stock anti-snap cylinders without modification.

Hardware selection

Options by premises type

The hardware specification follows the premises type, not the other way around. Select the column that matches your Slough property — the bullet list shows the typical hardware stack we specify in that category.

Retail

Shopfront

  • Aluminium glazed door or UPVC — Adams Rite, floor-spring closer, or multipoint gearbox
  • Primary cylinder on master-key circuit or standalone deadlock
  • Goods entrance on separate keying scheme, often padbar or hasp with insurer-grade padlock

Context Post-war business-park office unit where internal meeting rooms and break-out areas require basic keyed access only — no insurance obligation on these access points. Standard cylinders; key log opened; no compliance paperwork needed.

Professional

Office suite

  • BS3621 or EN1303 grade 4 cylinder on primary access door per most commercial insurance schedules
  • Internal zone doors on access-control grade cylinders — restricted keyway where staff turnover is high
  • Master-key scheme across multiple suites managed from a single key register

Context Estate commercial unit where the last inspection flagged the existing cylinder as substandard for the policy requirement. Upgrade to the named grade in a single visit — fixed price confirmed before the engineer attends.

Industrial

Industrial unit

  • Heavy-duty steel door sets — mortice deadlock, roller-shutter deadbolt, or padbar assembly
  • Goods-door padlock graded to the insurer requirement (EN12320 or BS EN 1303)
  • Alarm integration confirmation required before any cylinder is changed on monitored units

Context Industrial estate unit with shift-based or multi-team access where key-duplication control matters. Restricted keyway prevents copies being made outside the registered scheme — each keyholder entered against the authority card before a cut is issued.

After the job

Handover documentation: what leaves site

Every commercial attendance produces a paper trail. The three items below are issued as standard on all Slough commercial jobs — more complex master-key or access-control work adds a system chart to the set.

  1. 01

    Key schedule update

    An updated Simple log lists every keyholder by name, key number, and date of issue. Signed by the keyholder on site and countersigned by the attending engineer — the document your insurer may request at claim time.

  2. 02

    Installation certificate

    Where Compliance certificate or equivalent hardware is fitted, we issue a one-page certificate confirming the standard, cylinder grade, and door reference. Compliance certificate covers all access points visited in the same attendance.

  3. 03

    Audit trail / job card

    We noted a signed job card for every attendance. It records work scope, hardware fitted, and key counts — key count confirmed before we depart, paper copy left with the contact. Available as a PDF on request for insurance or lease compliance.

Fees and timescales

Commercial locksmith pricing in Slough

Smaller commercial units on estate locations use a simplified tier selection: the entry or standard tier covers most insurance requirements without the premium-grade hardware cost. Quote fixed and confirmed by phone. From £89.

Hardware grade
Standard euro cylinder sits at the base price; EN1303 grade 4 or 6, BS3621 mortice, and restricted keyways each carry a parts premium. Grade is confirmed against your insurance schedule before work starts — not after.
Number of access points
Each door in scope adds to the parts and labour total, but a multi-door attendance on the same Slough site is meaningfully cheaper per door than separate call-outs.
Master-key configuration
Setting up or extending a master-key scheme adds setup time. Once in place, the per-door changeover cost at each staff turnover or access review is lower than independent cylinder replacements.
Out-of-hours attendance
Evening and weekend availability in Slough — no out-of-hours uplift on the standard rate, and call-out included in the job price. Quote confirmed before the engineer travels.

Questions

Commercial locksmith FAQ: Slough

On estate-based commercial premises the most common trigger is an occupier change — rekeying the cylinder to lock out previous keyholders before the incoming occupier takes possession.

Does the keyholder always need to be physically present?
For new cylinder installations or master-key changes, yes — or a person with written delegated authority must be on site. For like-for-like replacements on documented hardware, we can proceed with remote authority if the keyholder is reachable by phone and their identity is on the prior job record. This is confirmed on the booking call, not on arrival.
What if the premises is on a managed lease — does the property owner need to be involved?
Check your lease. Most commercial leases in Slough require the occupier to notify the managing agent of any lock change within a stated period and to provide a copy of the updated key schedule. We issue the paperwork that satisfies that requirement — it is your responsibility to forward it to the relevant party.
How quickly can you attend a commercial site in Slough?
Planned work — rekeys, upgrades, master-key changes — is booked to suit your trading window, typically within one to three working days. Emergency lockout attendance in Slough is same-day in most cases. Quote confirmed on the call before we travel.

Commercial Locksmith in Slough — FAQ

Common questions about commercial locksmith in Slough.

Do you work with businesses in Slough out-of-hours?

Smaller commercial units on estate locations rarely need a master-key circuit — a straightforward rekey on a quality cylinder covers the insurance requirement and the access-control brief. Regularly — most commercial lock changes and master key installations are booked out-of-hours so business operations aren't disrupted. No out-of-hours surcharge; we work evenings, weekends, and overnight shifts across Slough at standard rates.

Do you work on commercial premises in Slough city centre and retail units?

Regularly — retail units, office suites, and hospitality venues in Slough are a regular part of our commercial work. We understand the operational constraints: retail units can't have doors secured improperly overnight, and offices often need lock changes completed before the next working day. We schedule accordingly.

Can you issue a VAT invoice?

Every commercial job gets a proper VAT invoice with our company number, VAT line separated, and payment terms clearly stated. Suitable for business accounting, Xero, QuickBooks, or any standard bookkeeping software.

Can you attend purely out-of-hours — we can't close during trading?

Yes — out-of-hours-only attendance is standard for retail, hospitality, and 24/7 operations across Slough. We schedule around your trading hours, coordinate with on-site security or duty managers, and leave you with a handover note and VAT invoice the next morning. No weekend or overnight surcharge.
