FYI, I did some testing over the weekend of the OEM Tire Pressure Monitors, and I found that replacing the battery does NOT cause the sensor to loose it's ID value, and it still functions properly after the battery is replaced. However, it may go into a "sleep mode" that it needs to be awakened out of. For now, everyone's bikes should still be under the three year warranty, and if you have a sensor go bad, I would encourage you to pursue getting a dealer to replace it under the warranty. If you have a sensor failure happen AFTER your factory warranty has expired, and you would like to try to replace the battery yourself, contact me and I will try to walk you through the process.
