Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First positive, then negative, and finally negative.
The presence of dirt or water could cause damage to the internal chip of the key fob. If your key fob stopped functioning after being soaked, clean it with isopropyl or electronic cleaner. Then, reinstall the battery. If the key ceases to function after being exposed to salted or soapy water, it is likely that the chip is fried and needs to be replaced.

Based on the model you have the fuse can be found in a variety of locations such as the engine bay, to the left of the dashboard, under the rear seat, or in the trunk.
