• Element Refurbishment: Technicians re-solder broken connections, change faulty 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 brand-New Key For Renault Trafic, pristine plastic shell.
• Checking: Before handing the card back to the client, the technician evaluates the remote frequency and the immobilizer chip on a devoted screening rig.
