Dead Coin Battery
A dead battery is probably the most common cause of your 500 key fob not functioning. Modern key fobs have a limited range of operation, and must be within a few feet of the vehicle to operate.

Water damage can occur in many ways, including a simple splash or submerging the key fob saltwater at the beach. If you suspect your fob has been exposed to water, you can try placing it in a dry rice bag to draw the moisture back out.

Water Damage
While the fob has some rubber seals to keep water out of the electronic chip inside and out of the ocean or washing it in a machine can cause water damage.

Receiver Module Issues
One of the simplest reasons your 500 key fob might stop functioning is that it's out of range. The remote typically has an area of 30 feet or less and if it's far from your vehicle, it won't respond to your commands. This can be fixed by moving it closer to your vehicle until it begins responding.
If your fob does not work after replacing the battery inside the coin, which is also known as a "button", "watch" or "button", it could be a problem with the internal circuit board.
