Radio Interference
When a key fob functioning properly, it emits a radio frequency signal that is received by the module in your car. If the signal is distorted in any way your key fob will not function properly. This may be due to factors like weather conditions, objects, or other transmitters operating on the same frequency band near your vehicle.

If your key quit working when it was wet, wipe the electronic component with isopropyl ethanol or an electronic cleaner prior to reinstalling the battery. If the key stops working after exposure to soapy or salted water, it is likely that the chip has been fried and needs to be replaced.

Based on the model you have, the fuse is located in a variety of locations including the engine bay, the side of the dashboard, beneath the rear seat, or in the trunk.
