I hit a pot hole the other night and immediately got a flat tire. After getting it home, I realized a little metal square had popped out of the wheel (see picture) and after a little bit of reading, I assume that this is part of the TPMS? And it popped out to keep the tire from blowing? My question is, what do I do now? Can that be put back, or do I need to buy something new to replace it? Obviously I am clueless about new car technology!
