Possible Causes

Incorrect PIN entered too many times, Damaged keypad or display, Corrupted security data in memory, Faulty security module

How to Fix / Troubleshooting

Safety first: Keep the mower in a secure location while security is disabled or being serviced.

  • Step 1 – Wait lockout period: If the mower is locked due to repeated wrong PIN entries, wait the specified lockout time and try again with the correct PIN.
  • Step 2 – Check keypad: Ensure the Sunseeker keypad buttons are not stuck or damaged. Clean around the keys with a dry cloth.
  • Step 3 – Master reset: If you have the master code or recovery procedure from Sunseeker, follow it to reset the PIN.

If E19 persists and you cannot unlock the mower, contact Sunseeker support with proof of ownership; the main board or security module may need replacement.
