TPMS Service at our Haines City shop

You can drive with it on, but you're driving blind on pressure from then on. That's a bad trade in a state where summer heat and long highway runs are already hard on underinflated tires.

Years, but not forever. The battery is sealed in the sensor and it runs down over time, and they usually start failing one at a time as a set gets older. There's no way to know the exact day, so we test them rather than guess.

No. It's sealed inside a molded housing, so replacing a dead sensor means a new sensor, not a new battery. Anyone who tells you otherwise is describing something these parts don't do.

No. Working sensors go right back in. What does get replaced at mounting is the service kit: the seals, grommet, and valve hardware around the sensor, since reusing those is how a slow leak starts.

The car has to know which sensor is at which corner, and that mapping changes when wheels move or sensors are replaced. The procedure differs by make and model, and some vehicles handle it on their own after a short drive.
