• Component Refurbishment: Technicians re-solder damaged connections, change malfunctioning microswitches, or repair harmed transponder coils.
• Shell Replacement: Because the initial casing must be cut open, technicians normally house the repaired circuit board inside a new, beautiful plastic shell.
• Testing: Before handing the card back to the consumer, the service technician checks the remote frequency and the immobilizer chip on a devoted testing rig.
