Portsmouth commercial access — door × lock family
Key audit and duplicate key recovery on a long-occupied southern commercial premises often uncovers a key population that exceeds the current register, particularly where the building has been in commercial use across several decades. We carry out a full key audit as part of the visit; use the matrix to identify the required tier and call to book.
| Door type | Primary lock | Supplementary | Add-on security |
|---|---|---|---|

| Composite / UPVC | Euro cyl 35/35, 40/40, 40/45 | Multipoint gearbox + hook lock | Sash jammers (accessible floors) |
| Aluminium glazed shopfront | Adams Rite 1850 / 4710 | Floor-mounted closer + hook | Mortice deadlock + key cyl |
The matrix is a starting point — we walk the job before quoting. Non-standard frames, fire-rated doors, and listed buildings change the spec — period shopfront access points audited for compliance grade before the tier selection is confirmed.

Compliance check
Insurance & BS3621 — the five-line check for Portsmouth premises
If a claim is being prepared or the risk assessment is under review, work through these five lines before the policy renewal. We can walk through them on the phone before attendance.
- 01 Check the insurance schedule — most Portsmouth commercial policies reference Oxford restricted compliance or equivalent as the minimum
- 02 Confirm the keyway — standard, restricted, or registered determines who can cut spares
- 03 Record the cylinder grade — EN1303 grade 4, 5 or 6 against each door in scope
- 04 Keep a signed key register — who holds what, dated, countersigned — East Anglian commercial handover: flint-frame keep fixing type noted in the handover record
- 05 Note which doors are on a multipoint — gearbox failures are a different call-out category
Commercial Locksmith in Portsmouth — FAQ
Common questions about commercial locksmith in Portsmouth.
Do you work with businesses in Portsmouth out-of-hours?
Oxford conservation-area commercial premises compliance questions: theassessment confirms the compliance grade required by both the insurer andthe conservation officer. Hardware that satisfies both requirements isspecified before any work is confirmed. 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 Portsmouth at standard rates.
Do you handle landlord/freeholder commercial lock work in mixed-use blocks?
Yes — communal entry and shared-service doors in mixed-use Portsmouth blocks (retail below, offices or flats above) are a regular part of our commercial work. We liaise with the block manager, attend outside business hours where the communal route affects trading, and invoice the freeholder or managing agent direct with VAT itemised.
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.
What's a master-key suite and do I need one?
A master-key suite is a set of locks where one "master" key opens all doors, while individual sub-keys only open specific doors. Useful when different staff need different levels of access — cleaners to common areas, managers to offices, directors to everything. Typical Portsmouth businesses with 5+ doors benefit from this kind of setup.
