If the key fob is not working even though it is not exposed to water, it could be due to a problem in the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob using an OBDII scanner may assist.
Water Damage
If your key fob's battery has taken submerged in a puddle or pool or gone down the wash machine, it could have some water damage. It is usually possible to get it working by taking out the batteries and cleaning the circuit board using ruby alcohol.

The key fob contains chip that communicates with the immobilizer system of the vehicle to begin it. The system relies on cryptocoding systems in the latest vehicles and the older red key system for older ones. This chip will have to be replaced if damaged.
A faulty 12 Volt battery
A defective battery can cause the key fob to function. The car's computer will not recognize the remote if this happens.
Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly, it's time to replace it.
Place an electrical load for a few seconds on the battery to gauge its capacity. This will remove 1% of the surface charges. Then, you can measure the voltage once more. The longer a battery can keep its voltage steady more effectively, the greater its capacity. The ideal scenario is to keep it close to 12 volts several minutes.
Faulty Radio Signal

Professional scan tools permit mechanics to observe the car's networks and conduct a variety self-tests. These tools can save a lot of time, but are expensive and are out of reach for the majority of DIYers.
If your OBD2 scan tool isn't turning on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape, it's likely that a fuse has failed. This is one of the most common reasons for failure of the scanner. The easiest fix is to replace the blown fuse.
