| "Card Not Detected" on dashboard | Broken internal transponder coil or dry solder joints. | Expert electronic repair or soldering. |
| Key works periodically | Loose internal components or a stopping working battery. | Test with a spare key and inspect internal circuitry. |
| Car begins, but remote buttons not do anything | Harmed RF transmitter or unpaired key. | Resync the key or repair the circuit board. |

- Element Refurbishment: Technicians re-solder damaged connections, change faulty microswitches, or repair damaged transponder coils.
- Shell Replacement: Because the initial housing needs to be cut open, service technicians usually house the fixed circuit board inside a new, beautiful plastic shell.
- Testing: Before handing the card back to the client, the professional evaluates the remote frequency and the immobilizer chip on a devoted screening rig.
Expense Comparison: Repair vs. Dealership Replacement
