4k memory card locked

[fuzzy1811]

I have a Digital 4K video camera recorder, and I have tried two different types of SD cards it's telling me its still locked. I pushed the switch and tried to format it but will not let me keeps saying memory card locked. Was wondering if I can do something with the camera that I have to fix it or need to bring it in and have someone fix it. Id likes to solve this on my own first before taking it in. Please help. i am using this for my business.

which brand and model of SD cards are you trying to use and which camera is it exactly?

Maybe the camera is not compatible with the SD cards or the SD cards are too slow for 4k video recording
