Reprogram cow-computer / step counter (TI 430F1122)

We use these transponders at a farm. They are put on the cows necklaces and register how much they move around / number of steps. Once a

day the cows pass by a reciever station (range 4m) that collects the data from the transponder.

The transponders are glued together and not supposed to change batteries. But now its getting harder to find new transponders to buy when

the battery runs out. The supplier want us to upgrade to a newer system with receiver unit and everything. I'd rather not..

I sliced one open and changed the ½AA battery in a unit that had lost all battery power. But the receiver won't recognize it now anyway

(each transponder unit has a 8-10 digit code / id).

Here are some pictures of the unit

I think the program is stored in the thing marked "430F1122"? Would it be possible somehow to read out the program from one of the units

that have not yet lost its battery power, change the unit ID and burn it in to one of the units with replaced battery?
