2018 Yaris keyfob not working

[CMJToyota]

The spare key fob for my 2018 yaris has stopped working.I imagine that the Battery needs changing but  there doesn’t seem to be any obvious way to get into it.Any advice on how to get it working again please?

That very much looks like an aftermarket key cover tbh.

That's a oem standard flip Key, the back cover clips off, use a small flat blade from the key ring loop

iirc it uses a CR2016

Thank you for your help. My previous fob had a small screw to loosen the cover and there wasn’t anything obvious with this one on how to open it. I didn’t want to damage it and end up with a stupid bill to replace it.
