Razer Blade 15 keyboards don't respond.

Hi razer community !
I recently try to put my ps4 controller with a toolkit program.
After that, my keyboard desn't respond.
I already change windows version mobdro kodi, reinstall all the pilots but nothing.
When i lauch synapse with an external keyboard , I can't access to chroma studio because he don't find any keyboards. The rgb lights works but can't be change.

Anyone could help me ?
