At its core, a key's blade must match the exact groove pattern of the lock cylinder. The cuts on the blade push pins to the shear line, permitting the cylinder to turn.
Electronic Authentication
For transponder and wise keys, the car's onboard computer system sends a low‑frequency signal to the key. The key replies with a special encrypted code. If the code matches the car's kept value, the immobilizer disengages, and the engine can begin.
Distance Detection
Smart keys discharge a constant radio frequency. When the lorry senses the key within a predetermined radius (normally 1-- 2 meters), it unlocks doors automatically and allows push‑button ignition. Many systems also require the driver to push a start button while the fob is inside the cabin.
