Safe travels,

I know that there is nothing on the outside that you can see but I am sure that your TPMS is part of the valve stem and is inside the rim, just like most automobiles. This means that when they die, you have to deflate the tire and replace the entire TPMS assembly which will include a new valve stem.
Not that difficult to do and not all that expensive but it can be a hassle when the internal battery starts to fail.
