When you are exploring the world of Rust, you might come across what looks like a locked door in a Monument. The only way for you to get inside these doors is if you complete a small objective and find a certain item. These items are Keycards. Keycards can be found in certain places and you can use them to open up the doors. The only downside to this is that there is a rarity to each card and getting them can be challenging sometimes.
There is a rarity for each of the cards with Green being the easiest to get, while Red is the hardest to get. Blue is in the middle so if you are going to get the Keycards, I would start with the Green cards if you can. There are 3 doors that you can open and each of the doors is opened with its respective Keycard color. Make sure you do everything right or else the door will not open for you when you finally use the card on the door. Here is an explanation of all the Keycards.

These puzzles need to be completed before you can use any Keycard on a door, but it is not that easy to complete. The Green Monument Puzzles are the easiest to complete but require you to flip a few switches around the Monument and then place a Fuse inside a Fuse Box. You can then go and open the Green door with your Keycard. The Blue Monument Puzzles are kind of hard to complete because the area in which you must complete the puzzle is a lot bigger than normal. It consists of turning on more power and Fuse switches so that you can get the door open.
It is a lot harder than Green because there is more stuff you have to do for it. The Red Monument Puzzles are the hardest to complete because they are the biggest puzzles to complete in the game. Not only are you running around in a very high radiation area, but you are also in an area that has many Scientists that are trying to kill you at the same time. Even though the Red doors are very hard to get into, the loot you get is totally worth your time and effort in the end.
Green Doors/Green Keycards
Green Doors are the easiest to get into and they give you some items that help in getting you into the next tiered door. There are a total of five Monuments that you can find these Green Keycards and they are the Lighthouse, Oxum’s Gas Station, Junkyard, Abandoned Supermarket, and Abandoned Cabins. You can also find one on a Scientist if you can take one out at a smaller Monument.
The puzzles are very simple to get into the Green Doors and is a good way to get some decent loot in the beginning of your adventure. Basically, if you wear a Radiation suit the entire time you do any Monument Puzzle in the entire game, then you will be safe from Radiation, but you should keep some Radiation Pills and Healing items just in case anything happens.
Blue Doors/Blue Keycards
Blue Doors are the medium puzzles in the game because it has the perfect loot for an average player. These Blue Cards can be found on Scientists or through the Green Doors in Harbor, Satellite Dish, and Sewer Branch. You can also purchase a Blue Keycard at an Outpost for 100 Scrap if you want to do that. Once you have a Blue Keycard, you may then go and open the Blue Doors once you complete the Puzzle before.
All you have to do is try to power the door with electricity and you may swipe the card and steal the loot. Remember that while you are trying to complete the puzzles, there may be an enemy waiting in the shadows for you to finish the puzzle and open the door so they can kill you and take everything you have and the loot inside the door has. Always be cautious of your surroundings because you could lose everything you have.
Red Doors/Red Keycards
Red Doors are the hardest door to get into because of the dangers before and all that you need to do to get in. The Red Cards can be found very rarely on Scientists or through the Blue Doors in Water Treatment Plant, Airfield, Power Plant, and Train Yard. You can get lucky if another player is selling it at the Bandit Camp, but it is up to them to how much people can buy it for. Remember that whenever you use a Keycard on a locked door to open it, it takes damage and is not infinite, so be cautious of how and when you use it.
The reason the Red Doors are soo hard to get into is that you need all three Keycards to actually open up the Red Doors. Also, you will need a Fuse to complete every Monument Puzzle there is to reroute the power to the door that you want to open. Remember that to actually get a Red Card, you actually have to complete many puzzles before it so don’t expect to open up a Red Door as soon as you start the game.
What does each door give you?
Each of the doors has a certain amount of loot hidden behind them. If you can get the door open, then you can take everything that is inside. It is not easy to get into each one, but it is totally worth it in the end. Here is what is behind each of the doors:
Green Doors – These doors contain 1-4 Normal Crates and a Blue Keycard in each one
Blue Doors – These doors contain 6-9 Normal Crates with a possibility for a Military Crate, and a Red Key Card in each one
Red Doors – These doors contains 2-3 Elite Crates, 2-3 Military Crates, and 2-3 Normal Crates
How many Monuments have these locked doors?
There are a total of 4 Monuments that have a Green Door, and they are Satellite Dish, Harbor 1, Harbor 2, and Sewer Branch. These have Easy Puzzles. There are a total of 4 Monuments that have a Blue Door, and they are Power Plant, Airfield, Trainyard, and Water Treatment Plant. These have Medium Puzzles. There are a total of 2 Monuments that have a Red Door, and they are Launch Site and Military Tunnels. These have Hard Puzzles. Every one of these Monuments has puzzles for you to complete and loot for you to get at the end. Make sure you are also looting the surrounding area for extra loot as well.
Why should I take the time to get into these doors?
Well, you could just play through the game while only using the natural areas for loot, but you can only get the extent of the items that you would be getting if you risked a lot to get into one of these doors. When you have all three of the Keycards, there is just something about it that makes you want to try and get to the Red Doors. All I am saying is if you want a rush of adventure and danger, then you should at least try to get into the Monuments and get the good loot, it is the least you could do.
In conclusion, the Keycard system is actually a really good addition to Rust. It helps you figure more out and it makes you feel better about actually putting the time in to get the loot. If you play Rust and you have not tried to get into the doors, I would highly recommend doing so to get better loot and unlock new blueprints. Just make sure that you unlock a blueprint first before using it because it could be gone and you have to find another one of those items.
