• Element Refurbishment: Technicians re-solder damaged connections, change faulty microswitches, or repair harmed transponder coils.
• Shell Replacement: Because the initial casing must be cut open, technicians usually house the fixed circuit board inside a new, pristine plastic shell.
• Evaluating: Before handing the card back to the client, the service technician tests the remote frequency and the immobilizer chip on a dedicated testing rig.
