Distance Detection
Smart secrets produce a constant radio frequency. When the car senses the key within a preset radius (normally 1-- 2 meters), it unlocks doors immediately and enables push‑button ignition. Numerous systems also need the chauffeur to press a start button while the fob is inside the cabin.

The Future of Auto Keys
The auto‑key landscape continues to evolve. Emerging trends consist of:
- Smartphone integration: Using NFC or Bluetooth to imitate a key through a devoted app. Biometric authentication: Fingerprint or facial recognition constructed into the start button.
