Distance Detection
Smart secrets emit a continuous radio frequency. When the lorry senses the key within a pre-programmed radius (normally 1-- 2 meters), it opens doors instantly and makes it possible for push‑button ignition. Lots of systems likewise require the chauffeur to press a start button while the fob is inside the cabin.
