2. Transponder Key
- Description: Metal key with an embedded RFID chip that communicates with the car's immobilizer. Security: Moderate (chip must be combined to the car). Normal Cost: ₤ 30-- ₤ 150.
3. Remote Keyless Entry (RKE) Fob
- Description: Plastic fob that combines a metal blade with radio‑frequency buttons for lock/unlock. Security: Moderate to high (rolling‑code technology). Normal Cost: ₤ 50-- ₤ 200.

The Future of Auto Keys
The auto‑key landscape continues to evolve. Emerging patterns include:
- Smartphone combination: Using NFC or Bluetooth to imitate a key by means of a dedicated app. Biometric authentication: Fingerprint or facial acknowledgment developed into the start button.
