Your TPMS can usually be re-used. However, in some cases, there is oxidation or general degradation which means they will break when pulled out and cannot be re-used. It is a good idea to replace the TMPS valves when reusing them cause sometimes they leak air when reused. Valves are cheap -- like 5-10 bucks per TMPS.
Its a good idea to replace the TPMS together since TPMS normally last about 5 years.
