To change the licence key on a FREAKHOSTING FiveM server, open Startup, paste the new key into FxServer License Key, click outside the field and restart the server. Licence key validation happens automatically: FXServer checks the key with Cfx.re every time it starts. Keymaster, where keys used to be made, is now the Cfx.re Portal.

How to change the licence key

1

Copy the new key

Sign in at portal.cfx.re, open your registered server and click Copy Key.
2

Open Startup

Open your server in the Game Panel and click Startup in the sidebar.
3

Replace the key

Select everything in FxServer License Key, paste the new key and click outside the field. It saves on its own.

Restart

Click Restart and watch the Console. If Cfx.re rejects the key, the console shows a licence error and the server stops.
Click Change it in Startup under Licence key on Server config to jump straight to this field.

​
Is Keymaster still used for FiveM licence keys?

No. Cfx.re replaced Keymaster (keymaster.fivem.net) with the Cfx.re Portal at portal.cfx.re. Guides and old pages that send you to Keymaster are out of date. Sign in to the Portal with the same Cfx.re account to see and manage your keys.

​
Is there a licence key validation API endpoint?

You don’t need one. FXServer validates the key with Cfx.re by itself when it starts; there is nothing for you to call or configure, and no URL to set in server.cfg. On FREAKHOSTING you only paste the key into Startup. If you are building tools around FiveM, use the official Cfx.re documentation as your source.

​
How to fix an invalid licence key

If the server stops during start-up with a licence error in the console, check these in order: Still stuck? Create a log link with Share log in the console and open a ticket. Keys and IP addresses are removed from shared logs automatically.

​
Frequently asked questions

​
Do I need to restart after changing the key?

Yes. The key is only read when the server starts, so restart the server after you change it.

​
Does a new key delete my server data?

No. Changing the key doesn’t touch your resources, server.cfg, txAdmin data or database.

​
Can I put the key in server.cfg instead?

Use Startup. FxServer License Key is a required variable on FREAKHOSTING FiveM servers, so keep your key there and nowhere else.

​
Do I need a new key to get more than 48 slots?

No. You keep the same key and add a FiveM Element Club subscription (Argentum or higher) to your Cfx.re account on the Portal. See how to change slots.
