Dead Coin Battery

A dead battery is probably the most common cause of your 500 key fob not working. Modern key fobs only have a limited range of operation and must be within a few inches of the vehicle to work. If you are further away from your vehicle and hit the keyfob, it will not respond and display the message "Key Fob Not Detected".

Water damage can occur in many ways, including an easy splash or submerging the key fob saltwater at the beach. If you believe your fob was exposed to water, place it in a rice bag to draw out the moisture. If this fails, you'll have to get your fob reset by an auto locksmith or a dealer.

Water Damage

The fob does have rubber seals to keep water from the chip's electronic circuit, 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 that can cause it to short out and eventually die. It's not a good idea to soak the fob in water but don't give up even if you accidentally drop the fob in water or forget to take it out of your pants pocket.

Remove the battery first. Before replacing the battery, clean the electronic chip using isopropyl or similar products. Check the fob to check if it's functioning. If the key still doesn't work, it may have to be reprogrammed. This is usually done by an auto locksmith or dealer.

Receiver Module Issues

One of the simplest reasons why your 500 key fob might stop functioning is because it's out of range. The remote has a range of 30 feet. So when you're too far from your vehicle it won't be able to respond to your commands. This can be fixed by moving closer to your vehicle until it begins responding.

If you've replaced the battery on your coin (commonly called"button" or "button" or "watch") and the fob isn't working, it could have an internal circuit board problem. In the majority of cases, reprogramming your fob will fix the problem. You can find directions on how to do this on the majority of automobiles by searching YouTube or looking through the owner's manual.

It could be necessary to replace the metal clips that hold the coin batteries in place. If they loose tension, it could prevent your coin battery from sitting properly and cause your remote to malfunction.

This could be a huge issue, but you are able to usually resolve this issue by visiting a local dealer or auto locksmith to have them reprogram your fob for you. In certain situations, they may need to reinstall the software on your body control module, as well.

Interference

In addition to a dead battery on a coin the key fob could not be receiving or transmitting the signal due to interference. This may happen if the keyfob is located in close proximity to a radio transmitter like a cellphone or radar detector. The key fob may not function due to a bad connection with the buttons or 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. replacing the battery, reprogramming, and using the spare key fob, it could 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 them into electronic commands that the vehicle interprets.

Fortunately, there's fiat key programming to reset every single system on board in your 500, including the key fob.
