The challenge of a multi-site property portfolio
Managing keys across several buildings (or even several towns) multiplies the risks: unmanageable bunches of keys, lost keys that are never traced, contractors holding master keys, costs that soar every time a lock is replaced. Without a structured master key system, the slightest incident means rekeying an entire site.
A multi-site master key system organises all access rights into a single, documented plan: a grand master key for management, sector master keys by site or by trade (maintenance, cleaning, security), and individual keys for each dwelling or room. You regain control, and every renewal becomes targeted rather than across the board.
Who is it for?
- Social landlords & social housing bodies (HLM): communal areas, plant rooms, cellars, bike stores, contractor access, across hundreds of dwellings
- Local authorities & town halls: schools, sports halls, technical services, community halls, administrative buildings
- Portfolio managers & property managers: office buildings, industrial sites, logistics hubs spread across several addresses
- Companies & multi-site networks: branches, retail outlets, franchises with a consistent access policy
Our approach to multi-site master key systems
- Centralised access plan: a key × door matrix designed to grow site by site
- Key records & key registration card: protected, traceable key copying, with additional keys ordered only by authorised persons
- Partial renewal: in the event of a loss or a departure, only the affected area is rekeyed, not the whole portfolio
- A2P high-security cylinders: certified protection against picking, drilling and bumping; see our A2P cylinders
- Standardisation: a single cylinder brand across the entire portfolio to simplify maintenance and stock
Combining mechanical keys and access control
Many portfolios combine a mechanical master key system (robust, no batteries, maintenance-free) with electronic access control at sensitive points. CLEFERM integrates both: Vigik fobs & building access for entrance halls and contractor access, connected electronic locks for detailed traceability, and mechanical cylinders for everything else. A preliminary audit determines the right balance: that is the purpose of our security consulting & audit.
How does a project work?
- Audit & survey: inventory of doors, sites and the access levels you need
- Master key plan: we formalise the key hierarchy and the key/door matrix, validated with you
- Quote & choice of brand: priced compatible options, from standard to A2P 3-star
- Production: made in our French workshop in Chatou or ordered from the supplier
- Phased roll-out: delivery site by site so that operations are never disrupted
- Follow-up & extensions: additional keys, new sites, renewals (your master key system keeps evolving)
