• Component Refurbishment: Technicians re-solder broken connections, replace faulty microswitches, or repair harmed transponder coils.
• Shell Replacement: Because the initial casing must be cut open, service technicians typically house the fixed circuit board inside a new, pristine plastic shell.
• Checking: Before handing the card back to the consumer, the specialist evaluates the remote frequency and the immobilizer chip on a dedicated testing rig.

Expense Comparison: Repair vs. Dealership Replacement
