Cheats in Cities Skylines aren’t openable in-game. You must go to the main menu and use the screen with the content manager. In the lines above I will show you how you could use cheats in Cities Skylines!
Content Manager
First, you must open Content Manager in the Main Menu of the game:

In this menu you could maintain content that is in game one of the screens is called “mods”. In this screen are some embedded mods which we could call cheats.

Inside of every game are these cheats:
- unlimited money => you will have ∞ money
- unlimited oil and ore => you can build oil and ore industry everywhere
- unlimited soil => you can do everything with landscape tools
- unlock all => you will have everything opened when starting
But before start playing with cheats I must say that when you play with cheats the game will be different. It could be less challenging so choose your goal well and what you expect from it. I don’t play with cheats.

- Intersection Marking Tool which helps you build the better and more realistic intersection
- City Vitals Watch which helps you to maintain your city and identify problems faster
- Realistic Population numbers of the population, workers will be more realistic
- Unlimited trees you could have unlimited trees on the map
- Empty it helps you maintain waste transfers
- Automatic Bulldoze destroys all abandoned and burned buildings
