I think the programming is in the monitor. All the sensor does is to sent temp and pressure readings.
All you have to do is change the battery.Programming will be fine.
This true to a certain extent, but the sensors have an identifying ID that tells the monitor where it is. If it didn't have an ID the monitor would have no idea where a particular sensor was located. But since the OP didn't specify what system he is referring to, it's hard to be exact. I have the TST system and the sensor batteries can be changed without the monitor losing its location.
