@ReeceDouglasTo help you try to get your remote working again have a look at these links to a couple of troubleshooting guides:
Troubleshooting guide
Remote help
You could also try holding the remote at both ends and giving it a gentle twist as though you were wringing out a cloth. Even though it sounds an unlikely solution it has got many faulty remotes working again (including mine on two occasions).
If none of the above help then I would request a replacement at the following link: Streaming TV replacement remote
If you have one available you can use a Sky Q remote while you wait for a replacement.
