Lost keys are a security risk. Copied keys are worse. BlueKey Pro eliminates both. Your phone becomes a secure, fully auditable digital key — authorized in seconds over Bluetooth, revoked just as fast. Every access event is logged, every permission is yours to control. Key features: Bluetooth key authorization — Issue or revoke digital keys to any user directly via Bluetooth. No physical handoff, no delays. Changes take effect the moment you confirm them. Granular lock-key permissions — Define precisely which locks each key can open. Supports one-to-many and many-to-one configurations, so complex real-world setups are handled with ease. Full access audit log — Every unlock is recorded: timestamp, key identity, and device details. Look back at any event, at any time, and know exactly who had access and when. Centralized management platform — Admins get a single dashboard for all locks and keys. Bulk operations, real-world status monitoring, and team-wide oversight — all in one place. BlueKey Pro is built for offices, short-term rentals, warehouses, campus labs, parking facilities, and anywhere physical key management creates friction or risk. All data is encrypted in transit and at rest. Bluetooth communication uses industry-standard secure protocols, so every authorization is protected end to end.
