| Doors Won't Unlock/Lock through Buttons | Dead CR2032 battery or microswitch failure inside the card. | Change the battery; if that stops working, solder new microswitches. |
| Car Starts, But Remote Fails | The RF (Radio Frequency) transmitter circuit is damaged or desoldered. | Check and repair the RF antenna connection on the circuit board. |
| Physical Cracks in the Casing | Resting on the card or basic pocket pressure. | Transfer internal electronics to a brand new replacement shell. |
| Total Failure After Getting Wet | Water ingress causing brief circuits and rust on the PCB. | Tidy the board with isopropyl alcohol and look for blown components. |
