Hello CocoaBrownsignsgreat772,

I’m sorry to hear about your Razer Tartarus Chroma not detected on Razer Synapse 2. One probable cause of this issue is the device's outdated drivers. To isolate the problem, please follow the steps from this article. If you need further assistance, PM me your keypad serial number so I can verify its model and provide other workarounds. Have a great day!
