Collect the card and make the computer usable

The box is in Zoe’s kitchen. Before attempting its locks, collect the Organ Transplant Card from the upstairs bathroom, reached through the bedroom on the right.

You also need the house’s computer email. The power meter is in a crawlspace beside the stairs; crouch to reach it and read the Power Card Credit Guide. If you cannot see, assemble the flashlight with the batteries found upstairs.

The prepaid power card is in the cash register at Peters Newsagent. Bring it back to the meter. Insert the card, use A to select its credit display, B to apply the credit, then operate the main switch. With power restored, turn on Zoe’s computer, refresh the inbox and read the email beginning “For Attending…”.

Choose the identifier the email is referring to

Use the email to determine which identifier on the transplant card applies. The matched identifier is ET956234692133.

The locks use its outside groups:

Lock Read from the matched identifier Enter
Left First three digits after ET 956
Right Final three digits 133

Return to the kitchen box and enter those two groups. The card has more than one printed identifier; grabbing a different number or the middle digits will not follow the email’s clue. The guides also describe needing Simon to learn that clue before opening the container, even if you already know the combination.

Use the lanyard and follow the new signal

Opening the box plays a scene and gives you Zoe’s Lanyard. Your next CRTV signal points toward Shorefront Family Clinic. Use the lanyard at the entrance reader.

In the clinic, collect the Scalpel before continuing to the pharmacy locker. Keep the lanyard: it later belongs on the right-hand clinic scale. Opening the organ container is a route prerequisite, rather than the end of the clinic’s three-item puzzle.

Check a missing prerequisite before trying more numbers

If the computer is still unavailable, confirm that you applied the prepaid card’s credit and then switched the power on. If the code does not open the box, inspect both the email and the transplant card rather than guessing another six-digit split.

If the box is already open, leave it and follow the clinic signal. The supplied sources do not document an alternate organ-box code for another puzzle difficulty.
