Found on many contemporary lorries with "Push-to-Start" ignitions, clever keys do not have a conventional blade that remains inserted in the ignition. Rather, the lorry identifies the fob's presence within the cabin via radio frequency recognition (RFID). These are the most costly and complicated to replace.

Action 3: Physical Key Cutting
Most fobs contain an "emergency key" tucked inside. This blade is used to unlock the door if the fob battery passes away. This blade needs to be cut utilizing a high-security laser cutter to match the lorry's mechanical locks.
