Something to be considered when tinkering with these TPMS modules is your car insurance cover. I would expect the TPMS to be considered a safety system by insurance companies. If it is not fitted, fine, but if fitted it should be fully operational to warn the driver of a potential partial deflation and blowout risk. If a TPMS sensor is tinkered with, no matter how well the work is carried out, it might present an insurance company with the ability to invalidate your insurance if you suffer an accident due to a tyre blowout. Just food for thought.
As has already been stated, it is common these days for devices in cars to be married to the associated processor module. New parts are often provided in what is called promiscuous state that the controller recognises and automatically marries to. The sensor then sets itself to non promiscuous mode and this is not normally reversible.
If, as has been stated, the TPMS system uses a countdown to EOL, that mirrors other safety systems such as heart starter Defibrillator batteries that have a built in electronic expiry algorithm for reasons of safety. If the TPMS has such a system, it would need to be reset if a new cell was fitted. If such is possible, it is usually detailed on the internet, as with printer cartridge resetting.
My experience of working on my 2005 Audi is that there are many modules married to the car that require a dealer system to access the OBD II port to reset or marry them to the cars systems. As stated, new parts are promiscuous, but used parts require a manual marrying process. I use VAGCOM for such work on my Audi but it would be worth some digging on the internet to discover how TPMS sensors are married to their controller and whether software for such acting via the OBD II port is needed.
