Dead Coin Battery

The most common reason your 500 key fob doesn't function is the battery is dead. Modern key fobs come with a limited operating range, and should be within just a few feet of the vehicle in order to function. If you are far from your vehicle and press the key fob button, the car won't respond and will display the "Key Fob Not Detected" message in the instrument cluster.

If this happens then replace the battery for your coin-cell (Part Number CR2032) by a fresh one of a trusted brand like Panasonic Duracell or Energizer. They are typically available at your local hardware store or online.

If the fob's remote doesn't work after replacing the battery, it could be damaged by water that blocks it from connecting to the receiver module in your vehicle. Water damage can happen through a variety of methods, including an easy splash or submerging the key fob saltwater at the beach. If you suspect that your fob has been exposed to water, try putting it in a dry rice bag to draw the moisture back out. If that doesn't work, the fob might need to be reprogrammed by an experienced auto locksmith or dealer.

Water Damage

While the fob has some rubber seals to keep water from the electronic chip inside it, submerging it in the ocean or washing it in a machine can cause water damage. Saltwater is especially dangerous to the circuit board of the fob, causing it to short out and eventually die. The fob getting wet is not an ideal idea however, if you drop it in the water in a cup or do not remember to take it out of your pants pocket prior to running the washing machine and you don't have a chance, don't give in.

First, remove the battery from the fob. Clean the electronic chip using isopropyl alcohol or a similar product and dry it thoroughly before replacing the battery. Next check the fob to test if it works. If the fob doesn't work, it may need to be reset. This is usually done by an auto locksmith or dealer.

Receiver Module Issues

The key fob might not function due to a bad connection with the buttons, water damage or damage to the internal chips.

If your key fob suddenly stopped working, or if you've tried everything at home to resolve it (e.g. It could be a defective 500 receiver module if you've tried replacing the battery, reprogramming it, or using an alternative key fob. The receiver module is situated under the dash and is able to pick up the radio frequency signals from the key fob. It converts them to electronic commands that the vehicle interprets.
