Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

An incorrect PIN code was entered. After five attempts the Automower keypad is blocked for a period. Wait, enter the correct PIN or use the app link to have it sent to your registered e-mail; if no e-mail is registered, contact Husqvarna.

Safety first

Stop and check this first

  • Do not try to bypass the PIN or the alarm: they are the mower's theft protection. On the high security level the alarm sounds if STOP is pushed and the PIN is not entered within 30 seconds or if the mower is lifted, and Husqvarna warns that it is very loud.

Safe checks you can perform

  • Wait for the keypad to unlock
  • Recover the PIN from the app
  • Write down the new PIN

Leave these tasks to a qualified professional

  • Do not attempt this professional task: PIN recovery through Husqvarna
  • Do not attempt this professional task: Security level review

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

    What they doIf you have no e-mail registered in the app, your local Husqvarna representative helps you regain access to the mower.

    They must show youthe mower accepting the new PIN.

    In writingthe procedure followed and any cost.

  2. Security level review

    What they doThe dealer can explain the three security levels (low, medium, high) and what each requires: PIN, alarm when STOP is pushed or when the mower is carried away.

    They must show youthe selected level in the Security menu.

    In writingthe level set and what it does.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Wait for the keypad to unlock

    No special tools

    Who:
    you.
    How:
    if the keypad is blocked, stop trying codes: each wrong attempt extends the lock. Wait until it accepts a PIN again and first look for the code written on the introduction page of the manual.
    Result that matters:
    not extending the lock and getting the correct code.
    If you find the written code:
    enter it once the keypad accepts input.
    If you have not written it down:
    recover it through the app.
    Evidence to keep:
    photo of the display with the message and the time.

  2. Recover the PIN from the app

    No special tools

    Who:
    you, with your Automower Connect account.
    How:
    use the link in the app to have the PIN code sent to your registered e-mail address, as the manual describes.
    Result that matters:
    receiving the PIN by e-mail.
    If the e-mail arrives:
    enter the PIN and, if you wish, change it under Settings > Security > Advanced > Change PIN-code.
    If you never registered an e-mail address:
    contact your local Husqvarna representative.
    Evidence to keep:
    screenshot of the e-mail received or of the request in the app.

  3. Write down the new PIN

    No special tools

    Who:
    you.
    How:
    if you change the PIN, the manual asks you to enter it twice and make a note of the new code. 0000 cannot be used.
    Result that matters:
    preventing the problem from happening again.
    If you note it somewhere safe:
    done.
    If several people use the mower:
    tell them the new code.
    Evidence to keep:
    note of the change with the date.
