Tyre pressure sensor problems

My Lexus LS460 has just passed its MOT but the main dealer has told me all the tyres need replacing soon as well as all the tyre pressure sensor valves at an extra cost of over £300 because the existing ones are supposedly corroded.

The monitors currently work and I've recently had all the valve caps off. Does removing the existing tyres automatically wreck the existing sensors?

No. Removing and replacing the tyres does not destroy the valve sensors, but mixed metal corrosion does.
