Lockstep Architecture

Unified Access PlatformHardware + Software in Sync

LynkD Sync gives secure access to any lock—no radios, hubs, wires, or apps. Rotating time‑window codes and a keypad‑first design cut complexity and cost while improving reliability and scale.

Dynamic Keys
Rotating windows (60s, 1h, 24h) give precise access that auto‑expires with full logs.
Radically Different
No Bluetooth, Wi‑Fi, NFC, or RFID. Just a keypad, battery, and secure code engine.
Battery Efficient
Designed for 8–10 years (model dependent) with a no‑radio, low‑power design.

Why Remove Radios?

Traditional systems add readers, radios, hubs, apps, and network setup—raising cost and risk. Lockstep removes the always‑on channel and keeps device and server in sync with rotating codes. Fewer parts mean less upkeep and fewer ways to fail.

  • • Lower Total Cost: No wiring or network enrollment.
  • • Higher Reliability: Fewer parts, fewer failures.
  • • Security by Reduction: Smaller firmware (<4K lines) vs large radio stacks.
  • • Granular Deployment: Secure cages, racks, and lockers economically.
Standard Access Flow
How a user gains entry with rotating codes.
  1. User identifies lock (QR / lookup)
  2. Authenticates (login / SSO / geo)
  3. Server validates policy & window
  4. Current valid code delivered
  5. User enters keypad code
  6. Device matches internal rolling state → unlock
  7. Event logged (who / what / where / when)
Offline / Edge Scenarios
Resilience without network.
  • Pre-generated hour / 24‑hour windows
  • Future dated codes for off‑grid jobs
  • Local audit until sync restored
Hardware Portfolio
Padlocks, lockboxes, and retrofit keypad modules built on a radio‑free code engine for decade‑long battery life.
  • Install anywhere (no wiring)
  • Time‑window codes (60s–24h)
  • Works down to racks and cages
  • Weather and tamper resistant

Retrofit Friendly

OEM engine (PCB + battery + actuator) drops into custom enclosures and legacy designs.

Policy First

Central key server checks who/what/where/when before issuing auto‑expiring codes.

Flexible Deploy

Start with one lock and scale to thousands—cloud‑managed or on‑prem—with full audit.
