After 15 minutes, connect the battery in reverse order: positive first, negative second.

Dirt or water can cause damage to the internal chip of the key fob. If your key fob stops working after being soaked, clean it using isopropyl or an electronic cleaner. After that, replace the battery. If it is not working after exposure to salty or soapy water the chip may be fried and will need to be replaced.

Another possibility is an inoperable antenna module fuse that sends the lock or unlock signal to the vehicle. The fuse can be found in a variety of places, based on the model. For instance, it could be under the rear seat, or in the trunk, or the side of the dashboard.
