The maintenance jack in Alien: Isolation is required to access rooms with braced doors. In the single-player campaign, it is a necessary tool to get through the main door and progress the story. To get it, players must retrieve it from the room left of Door 42 (the main door).
How to Get the Maintenance Jack
To get the maintenance jack, Ridley needs to retrieve it from the room left of Door 42. However, that room cannot open due to lack of power. In order to resupply power to the area, Ridley needs to go to the room on the right and restart the generator.
- Head to the room right of the main door (try not to step on any of the bodies along the way).
- Ignore exploring the area as everything is inaccessible for now.
- The power supply will be the first right you can take.
Once you’ve resupplied the power, you can head to the room left of Door 42 up the stairs. Once you enter, enter the door left of the save point and go through the door on the far right. You’ll see the jack behind a grate. To obtain it, climb the vent in the corner of the room and you should be able to drop down behind the grate. You can now use the maintenance jack to remove braces and unlock doors.
You can even visit the first room to collect some items from behind the braced door. The other doors are still locked and require an ion and plasma torch.
