Nimly lock problems... How do I set a PIN via a Flow?

The Nimly lock has a flow card which says “Set ID and Pin”. Tried to use it, ID:10 and PIN: 123456, the flow runs as it should but the code 123456 doesn´t work when I try it on the keypad, any suggestions?

The problem is fixed, it works to set a PIN via the flow card, it just needed some time for the lock to accept the new PIN. I don´t know the time needed but the new PIN worked after 12h when I tested it.
