• Part Refurbishment: Technicians re-solder broken connections, change defective microswitches, or repair damaged transponder coils.
• Shell Replacement: Because the initial housing should be cut open, technicians normally house the fixed circuit board inside a new, pristine plastic shell.
• Checking: Before handing the card back to the client, the service technician tests the remote frequency and the immobilizer chip on a dedicated testing rig.

Expense Comparison: Repair vs. Dealership Replacement
