Hey J, unfortunately yes. Since the reset button does not work, then you'd need to replace the unit, which you can use the RV Propane Gas and Carbon Monoxide Detector # RS34FR.

This replacement is also a carbon monoxide and propane detector, runs off of 12v power, and is white in color like the old one.

If there is anything else I can do to help, please feel free to drop a comment and let me know!

So I actually have the back one. I took the battery out and it's still going off I can't find a replacement like it and I'm worried about cutting the wires

@J Gotcha, then you'd want # RS44FR instead. For the wiring, just make sure you kill the main power before cutting any wires and you'll be fine.
