</>Common questions about Master Keys
What does Master Keys do in Construction Simulator?
Master Keys makes every base-game machine in Construction Simulator buyable at the dealer right away, with no waiting to level up first. Tap Unlock All Machines, reopen the dealer, and the full lineup of trucks, cranes, excavators and loaders is there ready to purchase. It's the fast route to the equipment you actually want to drive. Master Keys is a premium mod from ProjectMods, the community-first PC mod manager and desktop app for 400+ games. Pair it with Cash Printer and you can build a complete dream fleet in minutes, though owned add-on packs still need the add-on installed.
What does the Unlock All Machines button do?
Unlock All Machines is the single action inside Master Keys for Construction Simulator. Tap it and every base-game machine that's normally gated behind career rank becomes available at the dealer. One important detail: reopen the dealer after pressing it to see the newly unlocked lineup refresh in. From there each machine can be bought like any other. There's nothing else to configure; it's one button that opens the whole base-game catalogue at once. That makes Master Keys a quick way to go from a handful of starter machines to the entire yard being available for purchase in a single tap.
Does Master Keys unlock DLC and add-on machines too?
Master Keys opens up every base-game machine in Construction Simulator, but add-on and DLC machines still need their pack actually installed to appear. If you own an add-on, its machines show up as normal once that content is present; if you don't own it, Master Keys can't conjure it, since it only reaches the base-game lineup. So think of it as unlocking everything the core game ships with, right away, rather than granting content you haven't got. For the base roster of trucks, cranes, excavators and loaders, though, one tap of Unlock All Machines puts the whole lot on the dealer lot.
Do I still have to pay for the machines Master Keys unlocks?
Yes, Master Keys makes the machines available to buy in Construction Simulator rather than handing them over at no cost. After you tap Unlock All Machines, the full base-game lineup appears at the dealer, but each one still costs its normal in-game price to purchase. That's where Cash Printer comes in: with plenty of company cash on hand, you can snap up everything Master Keys just unlocked in one shopping trip. Used together, the two mods take you from a bare starter garage to a fully stocked yard almost instantly, while keeping the satisfying step of actually buying each machine yourself.
Why would I use Master Keys at the start of a Construction Simulator save?
Starting fresh in Construction Simulator normally means driving a small set of entry machines while you grind ranks to earn the good ones. Master Keys removes that wait: from your very first session, the entire base-game yard is available to buy, so you can pick the exact excavator, crane or truck you've been eyeing and build your ideal fleet immediately. It's perfect for players who know what they want and would rather design their company than unlock it piece by piece. Combined with Cash Printer, another mod in the ProjectMods catalog, day one can look like a fully-equipped operation.
