Is4 4 button spa worn out

I have a IntelliTouch iS4 Four-Function Spa-Side Remote connected to my Easy Touch control panel. Problem: The 4 buttons SPA/JETS/AIR BLOWER/LIGHTS  have apparently warn out. Do you sell just the control unit without the wiring or do I have to buy with the long wiring attached? Do I have any other options? Do generic models or wireless controlers work also? Don’t use the spa a lot and could use the 4 button controller closer to the panel itself. Any help would be greatly appreciated.  Thanks!

Hello Coatecity - Unfortunately, iS4 remotes are not available without the cable. We are not aware of an aftermarket replacement.

What color remote do you need and how many feet of cord would you require?
