Your key fob battery dying quickly could be due to several reasons: frequent use, which drains the battery faster, poor quality batteries, which have a shorter lifespan, being left in hot or cold environments, as extreme temperatures can affect battery life, or signal searching, where the fob continually searches for a signal if it's far from the vehicle. To extend battery life, use high-quality batteries, minimize exposure to extreme temperatures, and store your key fob closer to the vehicle if possible.
