Key Fob Entry Systems for Flats: A Guide for Landlords and Managing Agents

Why blocks switch from keys (and from old fobs)

Communal keys are unmanageable: copies multiply through tenants, trades and churn until the front door is effectively public — and one lost master means re-suiting the block. First-generation fob systems fixed the admin but not the security: 125kHz fobs clone trivially, so a 'controlled' door may have unknowable duplicates in circulation. Modern encrypted-credential systems close both gaps — auditability and clone resistance — and tie into door entry intercoms so one panel serves visitors and residents.

What managing agents get operationally

• Lost fob: deleted centrally in under a minute; new fob a few pounds — no locksmith, no leaseholder levy
• Move-outs and evictions: revoke without attending site or changing locks
• Trades access: time-limited fobs or codes for contractors, auto-expiring
• Event log: who entered which communal door when — invaluable for fly-tipping, ASB and insurance disputes
• Multi-door logic: bin store, gym, car park gate and roof plant each with their own permissions
• Per-block or portfolio-wide management from one cloud login

Costs and specification for a typical block

A single communal entrance with networked fob control typically runs £700–£1,200 installed including lock hardware; additional doors (bin stores, car park gates, plant) £500–£900 each. Encrypted fobs cost £3–£8 per resident. Pair it with a GSM or IP video intercom at the same entrance and the combined visit shares cabling and labour. Specify in writing: MIFARE DESFire credentials, fail-safe locking with fire interface on escape doors, and a management handover (your staff trained, not dependent on the installer for every fob).
