When placed into the ignition, the lorry's onboard computer system sends a signal to the chip. If the digital code matches, the engine begins. Replacing these requires both mechanical cutting and digital shows.
3. Laser-Cut Keys (Sidewinder Keys)
These keys are thicker than basic secrets and include a distinct winding groove cut into the center of the blade instead of notches on the edges. They use greater security since the lock cylinders are more intricate and the machinery required to cut them is more pricey.
