Distance Detection
Smart secrets discharge a consistent radio frequency. When the car senses the key within a predetermined radius (generally 1-- 2 meters), it opens doors immediately and allows push‑button ignition. Numerous systems also require the motorist to press a start button while the fob is inside the cabin.
