- Description: Metal key with an embedded RFID chip that communicates with the car's immobilizer. Security: Moderate (chip must be paired to the car). Common Cost: ₤ 30-- ₤ 150.
3. Remote Keyless Entry (RKE) Fob
- Description: Plastic fob that integrates a metal blade with radio‑frequency buttons for lock/unlock. Security: Moderate to high (rolling‑code innovation). Normal Cost: ₤ 50-- ₤ 200.
4. Smart Key/ Proximity Key
- Description: Keyless fob that detects the presence of the vehicle within a specified radius, allowing push‑button start and hands‑free door handling. Security: High (encrypted interaction, rolling‑code, in some cases biometric verification). Normal Cost: ₤ 150-- ₤ 400.

Proximity Detection
Smart secrets emit a constant radio frequency. When the automobile senses the key within a predetermined radius (normally 1-- 2 meters), it opens doors immediately and allows push‑button ignition. Lots of systems likewise require the driver to push a start button while the fob is inside the cabin.

Disable keyless entry when not in usage: If your car permits, switch off the distance function for added protection against relay attacks.
The Future of Auto Keys
The auto‑key landscape continues to progress. Emerging patterns consist of:
- Smartphone combination: Using NFC or Bluetooth to imitate a key by means of a devoted app. Biometric authentication: Fingerprint or facial acknowledgment built into the start button.
