• Element Refurbishment: Technicians re-solder damaged connections, replace malfunctioning microswitches, or repair damaged transponder coils.
• Shell Replacement: Because the initial housing must be cut open, technicians usually house the fixed circuit board inside a new, beautiful plastic shell.
• Testing: Before handing the card back to the customer, the professional checks the remote frequency and the immobilizer chip on a devoted testing rig.
