I'm reaching out regarding a lock issue we're currently facing. We've recently changed the battery, but we're still unable to unlock the device with the default code. It seems we might need additional assistance to resolve this problem. Could you please provide us with the master code along with any specific instructions on how to open the lock? Your guidance would be greatly appreciated so we can get this sorted out quickly. Thank you in advance for your support!
