Regards removing the sensors and replacing with new, I assume it's plug-and-play from an electrical point-of-view as long as they're 433MHz?

I assume I have to deflate each tyre in turn then and somehow pry the tyre back on the wheel where the valve is to get at the sensor on the inside of the wheel? Thought this would need a tyre shop - I only have have fairly basic tools...
The sensor is a part of the tyre valve. A reputable tyre shop will swap them for you. I’d probably wait till I need new tyres.
