Hi @lorilynn ,
It is usually easier to replace a keyboard than to try and fix it, as you can cause more problems than what you started with when attempting to repair them.
Here is a link to just one [https://www.amazon.com/Tsmine-RCT6973W43-Bluetooth-Keyboard-Rotating/dp/B06XDC9JHQ|supplier].
It is not a recommendation to use them. It is shown to give you an idea of the cost. There may be other suppliers that suit you better.
Just search online for ''RCT6973W43 keyboard'' for results.
Hopefully this is of some help.
