Hanex Bank vault puzzle: office keys, codes and DBN supply drop

Two office notes open two bank vaults; the notes inside lead to the DBN rooftop terminal.

In short

The recorded Hanex tower solution uses notes from Design Center Director’s Office and Netshin Security Office to open two vaults. Combine the three-digit fragments inside in their numbered order, then enter the result at the DBN Headquarters rooftop terminal. Use your own notes rather than a copied code.

Hanex Bank in The Grid has a two-vault puzzle leading to a supply drop at DBN Headquarters. Keep four notes separate: two open the vaults, and two found inside supply the final code.

Collect the two office codes

  1. Search the roof and floor below at Minsok Art School for Design Center Director’s Office. A pickup is filmed there; its presence in every match is not established. Take the key to Hanwoori Design Complex, use the elevator and open the named office. Record its note as the left vault code. This key is separate from Hanwoori Art Records Room.
  2. Search Hotel Lucera, starting with guest room 703, for Netshin Security Office. The walkthrough reports finding its key there. This does not establish a guaranteed spawn or a requirement to unlock the separate 703 bedroom. At Netshin, take the elevator, cross the hall and descend one floor to the office. Record its six-digit note for the other vault.

Label both codes before leaving. A screenshot of each complete note helps prevent confusing an office code with a later fragment. Clear the next approach before stopping to read.

Open Hanex Bank’s two vaults

Go upstairs in Hanex Bank to the vault area. Enter each office code at its respective vault. Search both interiors for notes marked 1/2 and 2/2. Each supplies three digits: join fragment 1 followed by fragment 2, preserving any leading zero.

Keep this combined number separate from the two original office codes. The nearby Hanex Guard Station uses its own key. The battery-and-card branch vault route covers different buildings and a different puzzle.

Use the DBN rooftop terminal

At DBN Headquarters, reach the roof and find the computer beside the helipad. Enter the combined six-digit number. The recorded completion calls a plane that drops a care package.

Safes and money appear inside the bank vaults, but the supply drop has no demonstrated exclusive reward. Plan this as an exploration objective, rather than a guaranteed Blueprint farm. Bring enough equipment and time for several high-rise interiors; check extraction options before making the final rooftop climb.

If the code fails

Check which stage you reached: an office key opens its office; an office note opens a bank vault; the numbered vault notes supply the DBN code. Re-read your own notes and their order. Do not substitute digits from Grid Assault, a branch bank or another deployment.
