Enter 45107 at the green factory Punch Card machine, collect the completed card and use it at the mechanical exit door. This is the solution documented in the linked Steam community walkthrough. Enter all five digits, including the 0 in fourth position. After the card gate, check the Blowtorch pickup before leaving the industrial route.
Input and pickup checklist
- 4
- 5
- 1
- 0
- 7
Enter all five positions from left to right. The fourth input is zero; collect the finished card after entering the code.
- Reach the factory's brick-walled office by its raised metal walkway. Look for the green desk machine, cabinets and paper tray.
- Read the nearby Override Protocol, then interact with the machine and follow its card-insertion prompt.
- Enter 4 → 5 → 1 → 0 → 7. Keep the zero; four key presses are not the same input.
- Interact again to take the finished Punch Card. Check the item name before walking back to the exit.
- Use the completed card at the matching mechanical-door reader. If the prompt asks for a card, check the physical item rather than entering the number at an unrelated panel.
The earlier route recording reaches the Punch Card around 1:55:56. That is a reference point in that video, not a target playtime or proof that your save uses the same build.
What should you collect after the door?
The Steam route places the Blowtorch on a barrel after the drop beyond the card door. Before committing to the next route, confirm that you collected it. It also opens the MP5 detour, so an optional weapon collection is another reason to keep the tool available.
Check the industrial route guide for the exit and missed-tool checks, then continue with the Prasnova route.
The machine or door still will not progress
| What you see | Next check |
|---|---|
| Input ends, but the exit still requests a card | Return to the machine and check its output. Completing the input and collecting the item are separate checks. |
| The number is rejected | Check all five digits and the machine's interaction state before another attempt. Compare the nearby protocol if your build differs. |
| Correct input fails on a launch build | Update first: Patch 1.01 fixed the puzzle rejecting a correct first attempt. |
| Inventory stops opening around the office | Leave the machine interface and test in a cleared area. If input remains disabled, use a protected earlier checkpoint and the specific factory checks. |
Sources and version context
Iron Blight Wiki reviewed the community's 45107 solution and the official first-attempt bug fix on October 9, 2026. The office description and video timing retain the earlier recorded-route evidence. The community walkthrough does not name its installed build; this page does not present the code as a new Patch 1.05 playtest. For surrounding pickups, use the key-item checklist.
