- Component Refurbishment: Technicians re-solder broken connections, change faulty microswitches, or repair damaged transponder coils.
- Shell Replacement: Because the initial housing must be cut open, service technicians generally house the repaired circuit board inside a new, pristine plastic shell.
- Testing: Before handing the card back to the consumer, the specialist checks the remote frequency and the immobilizer chip on a devoted screening rig.
