4. Smart Key/ Proximity Key
- Description: Keyless fob that discovers the presence of the lorry within a specified radius, permitting push‑button start and hands‑free door handling. Security: High (encrypted interaction, rolling‑code, sometimes biometric confirmation). Common Cost: ₤ 150-- ₤ 400.

Distance Detection
Smart secrets give off a consistent radio frequency. When the car senses the key within a pre-programmed radius (typically 1-- 2 meters), it opens doors instantly and enables push‑button ignition. Lots of systems likewise require the motorist to push a start button while the fob is inside the cabin.
