- Element Refurbishment: Technicians re-solder damaged connections, replace faulty microswitches, or repair damaged transponder coils.
- Shell Replacement: Because the initial case must be cut open, specialists normally house the fixed circuit board inside a brand-new, beautiful plastic shell.
- Testing: Before handing the card back to the consumer, the specialist checks the remote frequency and the immobilizer chip on a devoted testing rig.
