How do I change my FiveM license key?

Every FiveM server needs a valid license key from Cfx.re to start. If you need to replace your key — for example because it expired, is already in use on another server, or because you have a key with a higher slot limit — you can arrange it in a few minutes via Keymaster and the MC-Node panel.

Step 1: Create a new key on Cfx.re Keymaster

1. Go to the Cfx.re Keymaster website and log in with your Cfx.re account.
2. Click New server (or open an existing registration if you want to reuse it).
3. Fill in the requested details, such as the server name and the IP address of your MC-Node server. You can find the IP address in the panel on your server page.
4. After creating it, you will see the license key. Copy it in full; you will need it in a moment.

Note: a license key is tied to the IP address you enter in Keymaster. If the IP is wrong, FiveM will reject the key.

Step 2: Change the key in the MC-Node panel

1. Log in at panel.mc-node.net and open your FiveM server.
2. Go to the Startup tab.
3. Find the variable for the license key (usually labelled FiveM License or FIVEM_LICENSE).
4. Delete the old value and paste in your new key. Make sure there are no spaces before or after the key.
5. The change is saved automatically as soon as you leave the field.

Step 3: Restart your server

1. Go to the Console tab.
2. Click Restart (or Stop and then Start).
3. Watch the console output. If the server starts without key errors, the new key is active.

Fixing common key errors

• Invalid license key — The key was pasted incorrectly or is incomplete. Copy the key again from Keymaster and paste it into the startup variable without extra spaces or line breaks.
• Key is tied to another IP — Open your server registration in Keymaster and update the IP address to the IP of your MC-Node server. Then restart your server.
• Key already in use — One license key can only run on one active server at a time. Stop the other server or create an additional key in Keymaster.
• Key expired or deleted — Keys that you delete in Keymaster or that have expired no longer work. Create a new key and repeat steps 2 and 3.
• Server still won't start — Wait a few minutes; changes in Keymaster sometimes take a moment to come through. Then try again with a restart.
