Smart door keys without £1,500 lock-in

🛠️ The Open-Hardware DIY Route (Zero Vendor Lock-in)

Why pay £1,500+ for proprietary commercial controller boxes and expensive installers? If you are comfortable with basic tools, build your system using open, off-the-shelf standard components (Shelly smart relays, standard 12V electric strikes, and power supplies) at a fraction of the cost of commercial access systems. Already have an existing magnetic lock, electric strike, or 12V power supply? Reuse what you have — you only pay for what you actually need.

• · Open standard components
• · Reuse existing locks
• · Fraction of commercial PACS costs

📦 Professional Turnkey Setup ('Out of the Box')

Prefer a fully managed setup? We supply a neat branded enclosure housing the controllers and power modules above your door. Choose between a dedicated exact-date call-out (premium rate) or our budget-friendly flexible regional route scheduled when jobs are consolidated in your county.
