Distance Detection
Smart secrets give off a constant radio frequency. When the car senses the key within a pre-programmed radius (normally 1-- 2 meters), it opens doors instantly and allows push‑button ignition. Many systems likewise need the driver to press a start button while the fob is inside the cabin.
