This article systematically sorts out the acquisition and use of keys.

1. How to obtain Escape from Duckov keys

① Map search (most common keys)

Clothes pockets, drawers, filing cabinets, safes, and toolboxes are high-frequency locations. Especially clothes, it is easiest to get the key. You can basically touch it except for the color card. Try to touch all the clothes you encounter in the early stage. Judging from Xiao Er's physical sense, it is easy to get the key to the previous picture in the next picture. For example, if you are short of gray house keys or safe keys in Area Zero, go to the warehouse area. But this is not absolute. Once, the waiter found two keys to the gray house in the gray house.

②The boss drops drops (red, yellow, blue, mysterious keys, cellar cross-road keys)

The boss drops mainly several access cards in the laboratory, and they are also the keys that everyone is most likely to lack in the mid-term. A reminder to the newbies, don’t look at what’s in the room before you get the key card!

The red card is dropped by the question mark boss in Farm Town. It is difficult. It is best to clean up the black ducks around you before fighting. There is also a chance of red cards on the table in the blue card room (don’t ask me how I know this).

The yellow card has a probability of being dropped by the mysterious merchant in Farm Town. It can be brushed with the officially approved Puff Spray without any damage, or it can be killed from the card's perspective. The blue card has a chance to drop when you kill the farm town mine manager, because there are several tasks at this location, and the waiter is released when completing tasks. In addition, there is a high probability of getting a first-level certificate in the open air in the area where the mine manager is located.

The map boss troll at the radar station has a chance of dropping a mysterious key. I guess it’s because CH is afraid that the radar station is too poor and everyone won’t go there. The waiter on the ground at the radar station picked up the graphics card more than once. Killing the roadblock boss in the laboratory will always drop a level 3 certificate. You can use this to touch the container in the lower left corner of Area Zero. It is easy to get red. Kill the bomb maniac and drop the cellar crossroad key. Not only does he provide a large number of bombs to return the key, but he also earns about 1,000 from selling the key directly. He is a true philanthropist. If the waiter is short of incendiary bombs, he will come to him to pick up the goods. ③Fixed refresh point (purple card, principal’s office key, safe key, first and second level certificates)

During the second week of playing the game, the waiter also discovered some fixed refresh points. Everyone is welcome to add.

The principal's office key has a high probability of being refreshed in the school security booth, and the duck safe key has a high probability of being refreshed in the house in the lower left corner of the warehouse area. The small house in the upper right corner of the logging farm in Farm Town has a probability of refreshing the purple card. It is also affectionately called the purple card house. The area where the mine manager is located should be in a large rectangular walled area. Each one is fixed with a first-level voucher. You can search for the three required for the task. Level 2 certificates are usually found on the first floor of the laboratory, either in the open air or on a wanderer.

④Mysterious X/O Room

These two rooms are also quite unique. The upper limit can be used to produce crowns with the highest single item value. The waiter has swiped more than ten keys and has not yet released them. Usually the better things are various color cards and top-grade rifle spear. If you don’t want to try your luck, you can also use the camera function to go down into the room to see if there is a card before opening the door. These two rooms have been painted a lot, so all the keys can be collected.

⑤Black market/mysterious merchant (black card, mysterious key, other keys)

The mysterious merchant in Farm Town can buy black card (about 200,000), mysterious key

There are 5 refresh opportunities after reaching the full level in the black market. You can also buy keys and sell excess keys, but the randomness is quite high and it's a shame. The waiter suggested that all the mysterious keys should be used only once, and they could save money on the black market when large purchases are needed, so as to achieve financial freedom in one go.

2. Escape from Duckov key entry

There are still a lot of keys in this game. CH has opened up the permanent use function for most keys. Build a key entry machine at home. After entering the key, you can open the corresponding door at will. The waiter has posted the required materials here (circuit board + CD drive + metal sheet). They are easy to obtain. Remember to enter them as soon as you get the key. If you cannot enter, you need to use a key bag, which mainly includes the most popular X/O mysterious key, first to third level certificates, safe keys and two types of boat tickets, etc.

1. Inventory of specific locations where the Escape from Duckov key is used

(1) Area Zero

There are not many keys in Area Zero that can be used for a long time. After all, it is a novice village, but it does not mean that you cannot get red. Here, the waiter will sort out the places where all the keys in Area Zero are used.

①The debris fence key is located in the container area not far from the bunker entrance. After we unlock the teleportation beacon at this location, the teleportation point may be here. You can check it every time after entering the key. ②Gray House Key

The Gray House Key can be used at the L-shaped house next to the highway on the east side of the northwest camp. It is a check-in point that must be visited every time you get the key. It is a place where large goods are easily available in this area. ③Factory access card

With the factory access card, you can go to the gray house next to you after searching the gray house, and go to the gate to shoot ducks and open safes without detours. ④Safe key

The safe key can be obtained in the warehouse area. Each key can be opened five times. It is a pity that it cannot be entered like other keys. The opening location is at the teleport beacon guarded by the duck.

⑤Mechanical Key

This is a one-time mission prop. It is used at the end of the road on the lower right. You can go directly to it after coming out of the sewer. ⑥JLAB Voucher

It is not used in the early stage. This is for the storm area. The usage location is on the lower left side of the forest path. (2) Warehouse Area

The warehouse area has more keys than area zero. There are nine keys in total. The general map is attached below for easy reference.

The waiter will start from the east intersection camp in a counter-clockwise direction and take inventory of everyone in turn.

①Abandoned gas station key

Abandoned gas station should be your first goal in the warehouse area. After all, the teleportation beacon is unlocked here. In terms of output, this place has a high probability of shopping for shopping baskets. You can come here to get it when you have time. There will always be food and cash. If you run out of food after searching for a long time, you can come here to replenish it.

②Small compartment key and safe house compartment key

These two are very close to each other. They are located in the central part of the map. Both rooms are very fat. The BOSS is often spawned in this location. It is either the old climber or the rapid leader. When encountering the BOSS refresh interval, the waiter strongly recommends coming over and touching them. It is easy to get a big deal.

③ Private house key

The private house is located at the top of the map. If the evacuation point is in this area, you can set it as the last material collection point. There is a piece of clothing at the end of the room. I have found two mysterious keys here.

④Factory access card & factory office key

According to the waiter’s impression of the map, the team leader will most likely be in the west factory area to guard the factory office. If you have the factory office key, you must come and take a look. I got a lot of graphics cards and Bitcoins here. The factory access card is mainly used to quickly get to the private houses in the upper right corner. Sometimes it is useful if you want to evacuate quickly.

⑤Cellar Key&Cellar Fence Key&Cellar Crossing Key

The cellar area is located in the southwest corner of the map. You can use the cellar key to quickly enter the west factory area through the cellar. It is easy to brush Laodeng in this area. As a reminder, you must wear a gas mask when entering the cellar due to toxic fumes. Go down to the cellar and go to the right and use the fork key to see a new businessman. This key dropped on the farm town map, so you can ignore it in the later stages.

There is an area in the middle where you can use the fence key. In addition to the hot blood injection formula, there are also ammunition and weapon boxes. If you are short of weapons, you can come and touch them.

(3) Farm Town

The map of Farm Town is much larger. If the waiter’s calculation is correct, there should be 21 different keys. Let’s take stock of them next. The order of inventory is based on the location of the waiter's own tasks on the way as the starting point, and goes through it counterclockwise.

①Work shed key

is located behind the unfinished construction site. There is a container-style room. It is quite easy to find it alone.

② North Factory Cabin Key

In the northwest corner of the northern factory area, the evacuation point may also be nearby. You can use this room as the end of the route. Because it is a factory room, it is easy to find good things.

③Mysterious Key The explosion rate is higher than the mysterious key O. You can come and touch Bitcoins.

④Supermarket & Restaurant Compartment

These two are usually searched together by the waiter. The two together can still make a good profit. Friends with poor equipment can wait for Vader to come over and touch it when it is not refreshed. ⑤Mysterious Key O

This key is used in the hut next to the mercenary, and is generally one of the options for dog betting players. However, Xiao Er personally does not recommend that everyone consider this as the main source of income. ⑥Southern Factory Key Card

is equivalent to the admission ticket to the southern factory. You can open the four doors in the picture below. If you don’t have the key, this area will not be used. ⑦The iris information of the mine manager

If you kill the mine manager without a headshot, it will drop. You can open the hidden mine below. There are a lot of chassis inside. As for what you touch, you still have to look at the face. ⑧ Sanatorium Series Keys

There are four keys in the sanatorium. If you get them all, the lower right corner is still worthy of being the main target of a single trip.

⑨Staff dormitory 101/102/105 key

is the office building apartment where you will come to do the mud task. There are three keys in total. It is best to collect all three and touch them together.

⑩J-Lab Level 1 Certificate

is located on the basement floor of the office building. From here you can enter the test area. It is a next-level area with relatively high equipment requirements. It is best to graduate from Farm Town before going there. ⑪ Principal’s Office Key

This man Jeff's main mission check-in point can be obtained in the security room in the upper right corner. The whole school has this key, which is a rare and high-quality resource point. ⑫ Dormitory 101/103/106 key

is very similar to the employee dormitory above. The locations where the three keys are used are very close. This location is often guarded by double BOSS. In addition, the shipment at this location is not very good, so it can be more Buddhist. ⑬House Key 01

The house key is next to the entrance of our first farm town. CH is quite kind and generous in providing this little material.

The laboratory has two floors, and the waiter will take stock of them in order. Before we start, let’s talk about the common way to get all the keys, which are the two mysterious key rooms (X/O). If you touch them during the land reclamation process, you can effectively withdraw the money.

(4) Laboratory

(1) Basement level

There are 4 keys in the basement level, namely, J-Lab screening room key, J-Lab access card red, green, and blue. They are abbreviated by color below. ①J-Lab projection room key

It is easy to find the entrance to our laboratory. You can find it by walking straight ahead. Because it is a projection used in the projection room, it will be black when you cut the big map. This place has game cartridges and a J-Lab box, which is a good supply spot. The rest is the three-color access card, which also corresponds to the light color of the room on the map, making it easy to distinguish.

②Red Card The priority of the red card is relatively high, especially for those who want to get to the storm area of ​​the final map quickly. In addition to supplies, space protection helmets and advanced armor-piercing sniper bullets will also be purchased here. The mysterious boss wandering around the town has a chance to appear by swiping the red card. If you don’t want to fight the boss, you can wait for the open-air lab to swipe it. Touch the blue card room or touch the mystery room.

③Blue card Fixed refreshing color display blueprint. Friends who want full achievements, this is a must-do. There are cabinets where you can touch some mission items and replenish some medicines midway. If you don’t want to fight the mysterious BOSS, you can give priority to playing the blue card. The mine manager corresponding to the blue card is much simpler.

④Green Card The green card is in the lower right corner. There are a large number of chassis here. You can come and touch the graphics cards. There are also T7 thermal imaging blueprints that are needed to fight the stealth duck. In addition to the mysterious room, the obtaining location will also be refreshed near the prison on the second floor of the basement. Friends, you can keep your eyes peeled.

(1) The second underground floor

There are also 4 keys on the second underground floor, namely, J-Lab secondary certificate, J-Lab access card yellow, purple, and black. ①J-Lab Level 2 Voucher

The Level 2 Voucher is also a one-time item. You can enter the power control area after opening the door on the second floor, and you can fight the roadblock boss after opening the gate. In addition, there is a chance of using the space protective suit on the highlighted position where the waiter put the watermark. Remember to take a look after clearing the picture. The waiter must remind everyone here that there are spiders and invisible ducks in this area. Yes, you heard it right. Invisible.

In addition to super high movement speed in melee combat or low game difficulty, it is recommended that everyone get a thermal imaging or blindfold (plus a sensory totem) before coming over. The enemy cannot be seen and the sudden death rate is extremely high. ② Yellow Card The yellow card is next to the strange laboratory. Although the room is small and well-equipped, if you are lucky, you can touch the graduation weapons SPARE and M14. There are many ways to obtain yellow cards. There is a chance to swipe them on the laboratory table on the first floor. I got it through the mysterious merchant. When the waiter first arrived in Farm Town, the pet bag was full of locks.

③Purple card Purple card room is more about appearance. If you are lucky, you can pick up a graphics card. I came here and touched 2 cards. At the same time, I will always brush the three-in-one graphics card blueprint. Don’t rush to sell if you have enough graphics cards. With this formula, you can expand the computing power. Purple cards are easier to get. During the lumberyard mission, you can go to the small room next to the lumberyard. They are usually there.

④Black Card

The black card is quite special. The light color of the room is light blue. You can touch various potions here. The potions that Niba lacks during exercise may be replenished here. The blueprint for blackening DT will also be fixed. This weapon is also relatively easy to use.

There is a convenient way to get the black card. You can buy it with the mysterious merchant in Farm Town, but it is a bit expensive at 200,000. I personally recommend touching the mysterious key in your hand first. After all, if you are not lucky, you will have to make many trips to save up 200,000.
