- 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.
4. Smart Key/ Proximity Key
- Description: Keyless fob that spots the presence of the car within a specified radius, allowing push‑button start and hands‑free door handling. Security: High (encrypted interaction, rolling‑code, often biometric verification). Normal Cost: ₤ 150-- ₤ 400.

Distance Detection
Smart keys give off a continuous radio frequency. When the car senses the key within a preset radius (usually 1-- 2 meters), it unlocks doors automatically and enables push‑button ignition. Many systems also need the chauffeur to push a start button while the fob is inside the cabin.
