Possible Causes
Incorrect PIN entered too many times, Internal EEPROM error on main PCB, Keypad not reading digits correctly, Firmware corruption
How to Fix / Troubleshooting
Safety first: Ensure the mower is in a secure location while troubleshooting security-related issues.
- Wait lockout period: If multiple incorrect PIN attempts were made, wait the specified lockout time (see Hyundai manual) before trying again.
- Verify keypad function: Confirm that each number key registers correctly on the display. If some digits do not appear, the keypad is faulty.
- Factory reset (if supported): Some Hyundai models allow a factory reset via a hidden key combination or service menu. Follow the manual carefully; this may erase settings.
- Contact support for master code: If the PIN is lost or EEPROM is corrupted, you may need a dealer or Hyundai service center to reprogram or replace the main PCB.
