- Element Refurbishment: Technicians re-solder damaged connections, change malfunctioning microswitches, or repair damaged transponder coils.
- Shell Replacement: Because the original case should be cut open, service technicians generally house the repaired circuit board inside a brand-new, beautiful plastic shell.
- Evaluating: Before handing the card back to the customer, the service technician tests the remote frequency and the immobilizer chip on a devoted testing rig.
