• Element Refurbishment: Technicians re-solder damaged connections, replace faulty microswitches, or repair damaged transponder coils.
• Shell Replacement: Because the original case must be cut open, service technicians generally house the repaired circuit board inside a brand-new, beautiful plastic shell.
• Checking: Before handing the card back to the consumer, the service technician evaluates the remote frequency and the immobilizer chip on a devoted screening rig.

Cost Comparison: Repair vs. Dealership Replacement
