Fortunately, this is not difficult to fix. Find something absorbent, and place it inside the fob. Paper towl or tissue is ideal.

Dirt or water can harm the internal chip of the key fob. If your seat leon key programming has stopped working after being wet, wash the electronic component with isopropyl alcohol or an electronic cleaner prior to reinstalling the battery.
