Water damage can happen in a variety of ways, such as an easy splash or submerging the key fob in saltwater at the beach.

If that doesn't work, your fob may require reprogramming by a professional locksmith or dealer.

Water Damage

Although the fob is equipped with rubber seals to keep water from the electronic chip inside it, submerging it in the ocean or washing it in a machine could cause water damage. Saltwater can be particularly harmful to the circuit board of the fob which causes it to short out and eventually die. The fob getting wet is not an ideal idea, but if you drop it into an empty cup of water, or forget to take it out of your pocket before you run the washing machine Don't give up hope.

Take the battery off first. Before replacing the battery clean the electronic chip using isopropyl, or a similar product. Then try the fob and check if it functions. If the key does not function then it might need to be reset. This is typically done by a dealer or professional auto locksmith.

Receiver Module Issues

The 500 key fob you have may be inoperable because it's out of range. The remote typically has 30 feet of range or less, and if it's too far from your car, it will not respond to your commands. You can solve this problem by moving the remote closer to your car until it responds.

If the key fob has failed to work one day in the middle of the night or after trying every option at home to resolve it e.g. replacing the battery, reprogramming it and using the spare key fob, you may have a malfunctioning receiver module on your 500. The receiver module, located beneath the dashboard, detects radio frequency signals from your key fob. It converts the signals into electronic commands that are then interpreted by the vehicle.
