Running new Synapse 4, profile remaps some of the thumb buttons on my mouse(Basilisk Ultimate) to keyboard buttons like numbers, etc. which only work while Synapse is NOT running. While Synapse is running they seem to be captured or something. This is annoying when I want to control the lighting, but can’t have Synapse running if I want thebutton mapping to work.
Looking for a solution so that remapped key presses function properly while Synapse 4 is running.

My Basilisk V3 Pro mapping isn’t working with Synapse 4 running, nor with Synapse 4 off! The remapped buttons say “This mapping requires Razer Synapse.” Why isn’t this working properly?
I have the same problem with my mouse if synapse is running, did you find a solution?
hoping for an update that solves this but I’m not holding my breath. Luckily I have a the blackwidow v4 and those key maps are working, but I want my mouse to work fully too!
New update, my mouse ran out of battery so I had to plug it in directly with the USB-C. The remapped buttons started working. However, when I returned to wireless (2.4) mode, the remapped buttons stopped working again. Why is custom mapping only working on a wired connection?
the first part of this thread was absolutly correct, coles it and the mouse functions correctly, leave it running and it dosnt
It randomly started working again, after i restarted my pc.. i just don’t get it. One time it works fine and the other moment it stops again.. getting annoyed with it 
Same issue but with my my Tartarus Pro and Basilisk V3. NONE of the updated key maps work but the back color does change when a game is selected just the mappings arent working.
how the duck do you edit a reply, obviously one i have done!!!
Are any of you on the latest update of Windows 11 (24H2)? Thinking that might have something to do with it.
Has anyone fixed this issue? It seems it hasn't been fixed yet.
SAME ISSUE IS THERE A FIX ANYWHERE

Bluetooth and the 2.4 GHz dongle work. It seems the mouse dock pro was the issue on my end. Are you also using a mouse dock pro?
I’m using a Naga and have the same problem, did anyone find a solution? PLEASE!!
There is a workaround for it, I don’t know if it will temporarily fix it on your end, but if you want to make it work, try using a 2.4 GHZ dongle or Bluetooth connection, but if you are using a Mouse Dock (or 2.4GHZ dongle if the issue still exists) as a receiver, try logging out of your account and use the guest account instead, then create a new profile with the same keymaps.
SAME ISSUE AS ABOVE. I cannot set any custom keybindings to my Viper V3 Pro mouse side buttons. Ludicrous, this is the replacement mouse that Razer sent me for the last broken one that kept disconnecting. Losing faith in Razer.
My buttons will not remap on Viper V3 Pro in Synapse on the Wireless Dongle. When I connect through Synapse 4 with a wire, the buttons remap. But when I close Synapse, the buttons no longer work as mapped in Synapse while wired. And when I try editing the buttons in Synapse 4 with the Wireless Dongle they do not map - they do not work either with Synapse open or closed. Revo Uninstalled Synapse and deleted all trace program files and reinstalled anew and it is still the same issue. Tried logging in with a different profile, resetting the profile, and creating a new profile on a different account and it does not work. Please fix this!!
With Mouse Dock Pro: Same issue. Not working with Synapse 4 open. When I Exit Synapse 4, keybinds work.
Using included 2.4ghz dongle: Keybinds work with/without Synapse 4 open.
Using a Basilisk V3 Pro 35K + Mouse Dock Pro. Paging Razer. You need to FIX THIS!!!
I am having the same issues with my naga pro. The mapping does not work when using the dongle or with a Bluetooth connection.

I just got an email from Razer support. Let's see what they'll do about it.
I believe it's a software issue with Synapse 4 since you are having the same issue with your supplied dongle and not the Mouse Dock Pro.
Have you tried using Synapse 3? This is quite disappointing as these are my very first Razer products which I took a gamble on coming from Logitech peripherals.
I have a Basilisk V3 Pro and a Mouse Dock Pro. I cannot get the key mapping to work either, even the default key mapping layout doesn’t work for me. When will there be a fix for this?

I did that actually for the past few days, experimented with synapse 3 and 4 to see which one fixes my basilisk v3 pro and the dock. Synapse 3 works a lot better, but it has a separate annoying issue, every time I startup my pc the mouse isn’t detected until I re-plugged in the dongle.. But the mappings worked every time, so arguably better on 3.
Garbage razer software here and there either way.

I totally agree. Synapse and Chroma are both a hot mess and lagging behind their counterparts. Can't even save the RGB profile to the onboard mouse profile. In 2025. Sheesh.
That said though, I actually lucked out with a fresh install of Synapse 4. My remaps now work but not all of it. Particularly the Sensitivity Clutch button. I cant set it to anything else that would worknin-game.
First time I bought anything Razer and it kinda bit me in the ass 😂
