Third-Party Lighting System Activation Key

In order to provide a best in class end user experience and continue to provide the level of customer support our customers have come to expect, all Crestron 3-Series Control Systems purchased on or after March 1st, 2017 will require a Lighting System Activation Key in order to communicate with certain third-party lighting systems over IP. This communication provides instructions for purchasing the key, and attempts to answer any questions regarding it.

How do you purchase a third-party activation key?

To purchase a Third-party Activation Key visit the following website:

Third-Party Lighting System Activation: Key Request 

Please be prepared to provide the following:

  • The Hostname, System Key, and Serial Number of the 3-Series Control System to be activated. Instructions for obtaining these are included on the web page.
  • Purchase Order number. POs should include part numbers listed below and can be sent directly to





During normal business hours (Monday through Friday 9AM – 5:30PM Eastern Time), you should receive your Activation Key via email within an hour of submitting your request online. This email will include instructions for how to activate your 3-Series Control System®. These instructions are also included below.

After hours and on weekends the response will be delayed, but typically you should receive the Key within 24 hours. If you have an urgent need, please contact Customer Support.

How do you deploy the Activation Key to a 3-Series Control System?

Once you have received an Activation Key from Crestron, follow these steps to activate your 3-Series Control Processor:

  • Open the System Information tool in Crestron Toolbox and connect to the Control System to be activated
  • Select Functions > License Management from the menu bar
  • Click "Add" License tab
  • Paste the activation key above into the License Key field, and click "Apply"

What happens if I try to connect to a third-party lighting system without an Activation Key?

If a control system attempts to connect via IP to a third-party lighting system and no activation key is present, the connection will fail and a message will be added to the processor’s error log. This message will point you to the key request website listed above.

In addition, in the latest version of Crestron Toolbox you can use the "Diagnose" button in the System Info
tool to indicate whether or not your control system is in need of an Activation Key.

Are older 3-Series Control Systems affected when firmware is updated?

No. Any 3-Series Control Systems shipped prior to March 1st, 2017 does not require the Activation Key, even if it is uploaded to newer firmware.


What if I need to replace an activated 3-Series Control System?

If you have replace an activated 3-Series Control System for any reason, there are two options:

If you can still communicate with the “activated” control system

If you are able to communicate with the activated control system, you can use Crestron Toolbox to transfer the Key to the new control system. To do this, follow these steps:

  • Open Crestron Toolbox and connect to the activated control system
  • Select Functions > License Management from the menu bar
  • Click “Transfer” tab and follow the instructions

NOTE: You will need the System Key of the new control system in order to complete the transfer. Thus, you will need Toolbox access to both the activated and new control systems on hand in order to perform the transfer.

If you cannot communicate with the “activated” control system

If the activated control system is either non-responsive or is no longer in your possession, you can request a new Activation Key by contacting customer support. Please be prepared to supply the serial number of the activated control system.

What if I need to replace an older 3-Series Control System?

3-Series Control Systems sold prior to March 1st, 2017 did not require an Activation Key. However, if you need to replace an older unit for some reason, the replacement model may require an Activation Key. 

In this case, you should contact customer support and request a Key. Please be prepared to provide the serial number of the older control system.
