Hello.
From security reasons we don't provide unlock keys on public forum.
Please contact your Sales Manager or Distributor if you didn't buy this device directly from Teltonika and provide device IMEI and lock code.
If you don't have any contacts, with our Sale managers, please contact with them on our official website

Note: as a topic, please choose "Vehicle telematics".
Or you can send an e-mail with description of your situation to info@teltonika.lt
