How to Fix / Troubleshooting
Safety first: Keep the mower in a secure location while troubleshooting security issues.
- Verify PIN: Double‑check the correct PIN from your documentation. Ensure you are using the correct sequence and that no buttons are sticking.
- Keypad test: Press each button individually and confirm that it feels normal and registers on the display. If some keys do not respond, the keypad membrane may be faulty.
- Wait lockout period: Some models impose a delay after multiple wrong attempts. Leave the mower powered ON and wait the recommended time before trying again.
- Reset via manual: Consult the Flymo manual for any master reset or dealer reset procedure. Some models require service tools to reset the PIN.
- Hardware fault: If the correct PIN is rejected and the keypad is functional, the main PCB security circuit may be defective and require replacement.
