What is a key system?
Last updated
A key system is a check that stops a script from running until you enter a key: you get the key from the creator's key page, which usually sends you through a few ad pages first. The creator earns money from those ads, which is why so many free scripts and free executors use one.
How does a key system work?
- You run the script. It opens a key prompt, usually with a button that copies a link.
- You open the link in your browser. It takes you to the creator's key page, which sends you through one or more checkpoints.
- Each checkpoint is usually an ad page on a link service such as Linkvertise, Work.ink or LootLabs. These services show ads and pay the link owner for each visit.
- At the end you get a key. You paste it into the script, which checks it with the key service before loading.
- The key works for a set time that the creator chooses. When it runs out, you do it again.
Many scripts use a service such as Luarmor to run the key check. Luarmor adds a whitelist to a script, can tie a key to one device so it cannot be shared, and has its own ad checkpoints.
Why do scripts use key systems?
For money and control. The ad pages pay the creator, a key that runs out keeps people coming back to those pages, and a key tied to one device stops one key being shared by many people.
Paid scripts often use the same kind of system, except you buy the key instead of earning it through ads. Free executors work this way too: see free vs paid Roblox executors.
How do you tell a real key page from a scam?
Leave the page if any of these happen:
- It asks you to download or install anything: an app, a browser extension or a file "to get your key". Ad steps sometimes offer downloads, but you never need one to get a key.
- It asks for your Roblox username and password.
- It shows a warning that your phone or computer has a virus.
- It keeps sending you to new pages that have nothing to do with the script, and the steps never end.
- The Discord server linked to the script is empty, or the invite no longer works.
If a page asks to show you notifications, choose Block. Close any extra tabs the ad pages open, and only follow the steps on the creator's own key page. More warning signs are in are Roblox scripts safe to use.
How does ScriptBlox handle key systems?
- Key systems are allowed, but the uploader has to declare one with the Key system option and a real key link, so you know before you run the script.
- A key system may not include any downloads.
- Undeclared key systems are one of the reasons reviewers turn scripts down, and so is a key system our staff cannot complete.
- Scripts with no key system of any kind can carry the Keyless tag, and you can filter search results to show only those. Creators can apply for the Keyless Script Creator role.
The full list is in the upload rules, and the safety page shows how many scripts were turned down for each reason this week.
Questions
- Is it safe to complete a key system?
- The key itself is harmless. The risk is in the ad pages: misleading ads, fake warnings and download offers. Only follow the steps on the creator's key page, close extra tabs, and never install anything.
- Why did my key stop working?
- Keys run out after the time the creator set, and some are tied to one device, so a key from another device or from a friend will not work. Get a new one from the creator's key page.
- Can I find scripts without a key?
- Yes. On ScriptBlox, scripts with no key system can carry the Keyless tag, and the search filters can show only those scripts.
