TPMS sensor

[Sev90]

Hi all a quick question regarding the tyre pressure monitor system on my F Pace it has started to randomly lose contact with the rear driver wheel which I'm putting down to it's battery probably been nearly ten years old. As I'm about to have all 4 tyres replaced soon was wondering if it's a case of replacing the battery in them or should I just buy a full set of sensors and start a fresh. The tyres are going to sting me any way so don't want to have to pop them off later down the line when others start dying.  Thanks in advance Pete.
