Water Damage

Water damage can occur if you immerse the fob in the ocean, or wash it in a washing machine. Saltwater is particularly dangerous to the circuit board of the fob that can cause it to short out and eventually end up dying.

Receiver Module Issues

One of the simplest reasons why your 500 key fob may stop functioning is because it's out of range. The remote typically has 30 feet of range or less and if it's far away from your car it will not respond to your commands. It is possible to solve this issue by moving the remote closer to your car until it responds.

If you've replaced the battery on your coin (commonly called a "button" or "watch") and your fob doesn't function it could be due to an internal circuit board issue.

Interference

Interference can also cause the key fob to not receive or transmit signals.

Other reasons the key fob might not work could be due to a weak connection to the buttons, damage to the internal chip or water damage.

If the key fob has stopped working one day in the middle of the night and you've tried everything you can do at home to solve it e.g. replacing batteries, reprogramming or using the spare key fob, you might have a faulty receiver module on your 500. The receiver module is situated under the dash and is able to pick up the radio frequency signals from the key fob. It converts the signals into electronic commands, which are then interpreted by the vehicle.

Reconnect the battery. This will eliminate any remaining electricity and restart the car's computer system, which could help get your key fob working again.
