• Component Refurbishment: Technicians re-solder damaged connections, replace faulty microswitches, or repair harmed transponder coils.
• Shell Replacement: Because the original case should be cut open, technicians generally house the repaired circuit board inside a new, pristine plastic shell.
• Testing: Before handing the card back to the customer, the technician evaluates the remote frequency and the immobilizer chip on a devoted screening rig.
