Dumb TPS question for the day
I need to replace the battery in my front left tire sensor. I will be trying methods noted on this forum for the battery replacement. My dumb question is: Can I get the sensor off with out removing the tire, i.e. just letting air out of the tire and stepping on the tire while my buddy unscrews the sensor? Oh, I do have enough weight in my "spare tire" to deform the sidewall, like about 300 psi 
Just trying to save some time from going to the tire store to get the sensor out. Time=$$$

Thanks for the quick reply guys, i will get the tires dismounted and remove the sensors at home & replace the batteries. I figure I will give the replacement of the battery a try 1st before I spend the coin on new sensors. I work in the electronics field so if I ruin the circuit board I can probably repair it. It looks like the hard part is the removing the potting and choosing the right epoxy to replace it with.

If you have compressed air available, you can install the new/repaired sensors and reseat the tires without another trip to the tire shop if they have simply been broken from the bead. Be certain the tire shop that breaks the bead has marked the tire to show where it lines up with, say, the valve stem. This way when you air the tire back up it will be in correct placement with the balance weights on the rim.
Once you have the new TPMS installed (often helps to have a 2nd person available for this) you start blowing compressed air in through the valve stem. As you do this, be certain the tire is correctly oriented on the rim, and by pressing in on the tread area of the tire you should be able to get the bead to settle onto the wheel again. Usually most tire shops air the tire to its MAX rated air pressure (as marked on the sidewall) to ensure the tire has seated properly. Then lower the pressure to the correct amount (30 PSI) and install on the car.
