Dead Coin Battery

A dead battery is probably the most common cause of your 500 key fob not functioning. Modern key fobs offer limited operating range and must be within a few inches of your vehicle to work. If you are further away from your vehicle and you press the keyfob button, it won't respond and display the message "Key Fob Not Detected".

If this happens, simply replace the battery on your coin cell (Part number CR2032) with a brand new one from a reputable brand such as Panasonic, Duracell, or Energizer. You can find them at your local hardware store, or on the internet.

If the key fob won't function after replacing the battery, it could be damaged by water, which prevents it from communicating with the receiver module inside your vehicle. Water damage can occur through a variety of methods, including an easy splash or submerging your key fob in saltwater at the beach. If you suspect that your fob has been exposed to water, you can try placing it in a dry rice bag to pull the moisture out. If that doesn't work the fob might need to be reset by an experienced locksmith or dealer.

Water Damage

While the fob comes with rubber seals that keep water from the electronic chip inside the device, submerging it into the ocean or washing it in a machine could cause water damage. Saltwater is particularly dangerous to the fob's circuit board and can cause it to short out and eventually end up dying. Getting the fob wet is not an ideal idea however, if you drop it in an empty cup of water, or fail to take it out of your pants pocket before running the washing machine and you don't have a chance, don't give in.

Take the battery off first. Before replacing the battery clean the electronic chip using isopropyl or similar products. Then test the fob to see if it works. If the key still doesn't function, it may need to be changed. This is typically done by a professional or dealer auto locksmith.

If the key is a newer model and has never been programmed to your car it is likely to need to be replaced completely. A professional locksmith for cars can carry out this simple task. The locksmith must cut the key to match the ignition on your vehicle. The locksmith will also have to reprogram your fob into the vehicle's system. This is a cost-effective and fast process that can be completed on the same day.

Receiver Module Issues

The 500 key fob you have may not function because it's out of range. The remote typically has a range of 30 feet or less and if it's far from your vehicle, it will not respond to your commands. You can easily remedy this by moving your remote closer to your vehicle until it responds.

If your fob isn't working after you replace the battery inside the coin, which is also called a "button", "watch" or "button" it could be due to a problem with the circuit board inside. Reprogramming your fob can resolve the issue. The instructions are available for most vehicles on YouTube or in the owner's guide.

It is sometimes necessary to replace the clips made of metal that hold the coin batteries in place. If they lose tension, it may prevent your battery from sitting properly and cause your remote to malfunction.

In rare cases, the fob may become disconnected from your vehicle due to software problems or hardware issues. It is possible to fix this issue by visiting your local dealer or auto-locksmith to reprogram your key fob. In some cases it is possible that the software will require reinstallation to your body control modules.

Interference

Other reasons why the key fob may not function include a poor connection to the buttons, damage to the internal chip or water damage.

If the key fob suddenly stopped working, suddenly or even after trying every option at home to fix it e.g. replacing batteries, reprogramming or using the spare key fob, it could have a damaged receiver module on your 500. The receiver module, located under the dashboard, picks up radio frequency signals from your key fob. It transforms the signals into electronic commands, which are then interpreted by the vehicle.

There is a straightforward method to reset the 500's internal system including the keyfob. Disconnect the 12 volt battery for approximately 15 minutes by disconnecting the negative cable first then the positive cable. Reconnect the battery. This will erase any remaining electricity, and allow you to restart the car's computer. This can help get your key fob to function again.
