Dead Coin Battery

A dead battery is the most frequent 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 in order to work. If G28 Car Keys are far from your vehicle and you press the keyfob button, it will not respond and display the message "Key Fob Not Detected".

After you've replaced the battery of your coin cell It is possible to test it by standing in front of your Fiat 500 and pressing the buttons. The car should flash its parking lights and the key fob will operate the lock and unlock switches.

If the key fob won't work after replacing the battery, it might have water damage that stops it from communicating with the receiver module inside your vehicle. Water damage can happen in a number of ways, from small splashes to submerging your fob in salt water at the beach. If you suspect that your fob has been exposed to water, put it in a rice bag to draw out the moisture. If this doesn't work, you will have to get your fob replaced by an auto locksmith or a dealer.

Water Damage

While the fob comes with rubber seals that keep water out of the chip's electronic circuit, submerging it in the ocean or washing it in a machine could cause water damage. Saltwater poses a particular risk to the fob's circuit board which causes it to short out and eventually die. If you get the fob wet, it's not a good idea but if you accidentally drop it into a cup of water or fail to remove it from your pants pocket prior to running the washer Don't give up hope.

First, remove the battery from the fob. Clean the electronic chip using isopropyl or a similar product and then dry it thoroughly before replacing the battery. Check the fob to verify if it's working. If the key does not function then it might need to be changed. This is usually handled by an auto locksmith or dealer.

If the key is more recent and has not been programmed to your vehicle, it will likely need to be replaced completely.

The locksmith also needs to reprogram your fob into the vehicle's system. This is a fast and cost-effective process that can be completed on the next day.

Receiver Module Issues

Your 500 key fob might stop working because it is out of range. The remote usually has 30 feet of range or less and if it's far from your car, it will not respond to your commands. This can be easily fixed by moving it closer to your vehicle until it begins responding.

If your fob doesn't work after replacing the coin battery, also called a "button", "watch" or "button", it could be due to a problem with the circuit board inside. Reprogramming the fob usually resolves this issue. You can find directions on how to do this for most vehicles by searching YouTube or checking out the owner's manual.

You may have to replace the metal clips that keep the coin battery in place. If they lose tension it can prevent your coin battery from sitting properly, causing your remote to malfunction.

This could cause a significant headache, but you can frequently fix this issue by visiting an auto locksmith to have them reprogram your fob for you. In some instances it is possible that the software will require reinstallation into your body control modules.

Interference

In addition to a dead coin battery the key fob could not be receiving or transmitting the signal due to interference. This could occur if the key fob is located near a radio transmitter (cell phones, radar detectors) or another source of electromagnetic radiation. The key fob could not work because of a weak connection with the buttons, water damage or damage to the internal chips.

If the key fob has suddenly stopped working, without notice, or after trying everything you can do at home to fix it e.g. You may have a faulty 500 receiver module If you've tried replacing it with a battery, reprogramming, or using a spare key fob. The receiver module is situated under the dash, and it picks up the radio frequency signals from the key fob. It converts the signals into electronic commands which are then translated by the vehicle.

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