How to Unlock Tangaroa Tower Code
Okay, I’ll assume you’ve reached the 3rd floor tower and found the Keypad, so. Open your journal (Press T). Go to Last Page.

On the page is a paper showing the words, underscores, and 4 images.
In the first column, you’ll find the street name. The second column shows the code for the tower. The third column contains the building icon image. To get the code, go to the street listed in the first column. Look for the building that has the same icon shown in the third column. The code will be found on the Building Number.
Then the format to find the code is [Street Name]_[Building Number]_[Building Icon].

Nice guide for those less intuitive folk. Was pretty straight forward to figure out. But can see how younger kids and stuff can get stuff.
Ahhh soo i and some friends i play with have a problem so this bridge is now on sea but the problem is that this trapdoor is closed we cant get in, and we did everything what the game want (i think)
I had the same problem.
Try to restart the game. That should help you. At least that helped me.
