Right arrow key stops working on bluetooth keyboard

Hi guys, Does anyone have this issue with bluetooth keyboards? The right arrow key stops working but when it’s on charge, it works just fine. The weird thing is I can take it off the charger and it will work for a while but then stop working again. All of the other keys work perfectly on or off the charger. Just the right arrow stops. I’ve reset the keyboard dozens of times and it still does it. I’ve even told my device to forget the device and then pare it again. I’m using a new ipad that I just got for Christmas. I have a mini already but my dad wanted to get me a new one. One that was more up-to-date. It is sixth generation with 32 gigs of space.Thank you all in advance.
