The early 2000s saw the rise of remote keyless entry (RKE) fobs, which enabled motorists to lock and open doors at the press of a button. Today, smart secrets, likewise called distance keys, enable key‑less start and hands‑free door activation, marking the peak of auto‑key evolution.

Proximity Detection
Smart keys emit a consistent radio frequency. When the car senses the key within a predetermined radius (usually 1-- 2 meters), it opens doors instantly and allows push‑button ignition.
