The wireless remote is powered by a CR2032 3V lithium battery and it could be that it's run out of juice. We recommend the first step in troubleshooting is to replace the battery. The CR2032 3V battery is commonly found in retail stores like Walmart, Target, or other local convenient stores.
To replace the battery you will need to use a precision Philips screwdriver to remove the four corner screws underneath the remote. Remove the cover to access the PCB holding the CR2032 battery. Swap in a new one and reassemble the unit.
After that you should be good to go! 😀
