My Tartus v2 wont let me use my custom key maps after the latest update. It says I need Synapse 4 running, which it is. I tried the repair options, I also tried a clean re-install. But nothing. I use this for both work and gamming, so this really has me in a bind as it was apart of my workflow. Any help would be appreciated. Im on windows 10 but with the most updated security features.
Question
Tartus v2 and Synapse 4 issue with Sept 2026 update
Welcome to the Club, I had to restore an OS image with Macrium Reflect from 1 week ago which had the older version of Synaspe before the sept Update to get it working again.
Anything come of this? still broken here
I saw I had updated yesterday, but it was still broken for me. I tried it again today just about an hour ago and suddenly the d-pad on my Tartarus v2 is working once again - and so are my keybinds. Fingers crossed it stays that way.
I have been able to restore functionality after working with Razer Support. I had to follow these steps *exactly* to get it to work, so I can only assume it was something in the driver code itself that glitched out.
The following is from the last email I received and was able to restore functionality with.
2. Driver Cleanup Tools in sequence.We understand that you have previously attempted to use the Driver Cleanup Tools. However, we recommend trying the following alternative steps. Please ensure that each step is followed carefully and in sequence to achieve the best results.
- Uninstall Synapse and Chroma (ensure both are uninstalled, not just one): How to uninstall Razer Synapse 4 from your Windows PC or laptop
- Run the latest driver clean-up tool: https://rzr.to/igxb6b
- Restart your PC.
- Download and install Synapse 4 from our support page: Razer Synapse 4: Advanced Device Control and Lighting Software
- Launch Synapse 4, then restart your PC again after the driver is installed via Synapse, and test the functionality.
Sorry, it still doesn’t work… unfortunately! 😩
Did a install of Synapse on another SSD with Windows 10 that never has had Synapse. Still the problem exsists.

What do you mean? I use Tartarus pro without Synapse. It's half a keyboard the odd button is alt and the dpad is up down left right. 20 is spacebar. Works great. The only thing I did in Synapse was make the scroll wheel volume control. Scroll click was T.
