IN Atomic Heart locks can be found on every turn. Some of them open shortcuts to return to the location, others hide drawings and various resources behind them. In this guide, we look at all the types of locks found in the game and tell you how to open them.

Remark: When locks are broken, time in the game does not stop. This means that a robot that comes close to P-3 can notice and attack. Therefore, we recommend that you only start hacking when you have to deal with all the opponents in the vicinity.
Over time, the castles in the game become more and more difficult, and sometimes you can end up in a dead end. If this happened to you, move away from the door and reactivate the hack by clicking F (X on controller).
Also, the player can sometimes encounter a fortified castle that contains two types of puzzles. With the keys you can switch between the latter a And D.
How to open a lock with clicks
The very first type of castles found in the game. To open such doors, you need to snap your fingers in time so that all the fuse pins are in the mechanism and the lights turn green.
The active pin is illuminated by a light and in the beginning it is not difficult to click at the right time. The problems start when most of the lights are already green and the pins are in the correct position – clicking at the wrong time in this case unlocks the pin and needs to be replaced.

Also keep in mind that with each successful activation of the fuse, the direction of movement of the light is reversed, and at first this may confuse you. We recommend not focusing on the image, but on the sound.
In fact, the universal “key” for all locks of this type sounds like this: click-click-skip-click-skip-skip-click. First two clicks, then skip the metronome beat, then click again, skip two beats, click, and so on.
Over time, you will adapt in seconds and pick locks without even thinking about it. If you have a hard time with it and are afraid of not being on time, don’t worry – when the time is up, the fuses will simply return to their original positions and you can try again.
How to open a lock with colored dots
Perhaps this is the most difficult type of slot in the game, as it is quite difficult to understand how this puzzle works. We need to arrange the colored dots so that their color matches the color of the dots on the fuses.
To do this, we have two actions available: rotate the rotary knob and move three points relative to each other. Turning the rotary knob shifts all points three positions to the left or right. Moving three points is performed at the bottom of the castle. Each click will “shift” the first two points to the right and the third will move from the right border to the left. For clarity, we provide screenshots.
Often it is necessary to correctly position two or three points, which is not a difficult task. We recommend that you first “connect” one pair and then, based on their location on the dial, select the rest of the colors.
Also note that each time the puzzle is activated, the colors and their location change, so if you get confused or the option suggested by the game turns out to be too difficult, you can just exit the minigame and start hacking again .
How to open graphic locks
These locks are an analogue of the graphic keys we are used to. To open them, you need to light certain lamps. Due to the selection method, you are unlikely to be able to open such a door – there may be too many combinations. Next to such locks you can always find a drawing with a hint, which indicates the necessary light bulbs.
Since P-3 doesn’t have a habit of cleaning up waste paper, you’ll need to remember the correct light bulbs or take a screenshot of the number to reproduce it later on the lock panel.
How to open a cookie lock. Where can I find the electronic key?
Cookie locks are similar to dotted combination locks, except you don’t have to remember anything. You just have to look around the location and find the key in the shape of a cookie, then return to the castle. If you have the necessary key card in your inventory, Nechaev will put it in the well and open the door.
There are only a few such castles in the entire game, and most of the time we somehow come across a place where cookies are “stored” in the story. An exception is access to the bunker of one of the landfill sites. The key that opens this door is in a far from obvious place. But you can refer to this guide to find out how to open all the polygons in the game.
How to solve puzzles with power relays and dials
Such locks at the company closed hermetic doors to important areas of the complex. To open them, you must first solve a small puzzle. Several rotating discs and three lasers of different colors – red or green – appear on the wall or on the floor. They will all converge at one point with three light bulbs.

The color of the lasers must match the color of the lamps they focus on. That is, relatively speaking, if the top and center lights are green, then the center and top lasers should have green beams at the focus point.
This can be achieved by sliding the turntables V(RB). Some nodes have special markers that “split” the beam. We’ve highlighted them in the screenshot below. This way you can achieve the desired color in the focus area. Turntables only move such splitters up and down – moving them sideways will not work, but this is not necessary.
How to open a padlock with a keyhole
Keyholes are another fairly basic type of lock that can be found in regular Enterprise offices or the living quarters. If you have played The Elder Scrolls 5: Skyrim or the Fallout games (Fallout 3 and Fallout 4), you immediately understand the principle of hacking. It is necessary to move the mouse, adjust the inclination of the HRAZ antennas, and also regularly press the LMB to check whether the lock lends itself.

If you see the keyhole turning more and more, you’re on the right track. There are no master keys in the game and with the necessary perseverance you can easily go through all possible positions.

Of course, there are other castles in the game, but they are part of the plot and obey not prescribed mechanics, but scripts. For example, to enter the Enterprise’s next location, we need to use telekinesis to move one of the statues away and have time to sneak into the opened passage before the statue falls into place.
