Reasons Your Fiat 500 Key Fob Won't Work
A fiat 500 key fob is a handy way to unlock the doors and get started the car. There are many reasons why the fob won't work. This could be due to a dead coin-battery or water damage, receiver modules issues, and interference.
This listing is for a NEW replacement Fiat Flip Key Remote - an exact replica of the Ilco brand that needs to be programmed professionally by a local automotive locksmith (click here for Locksmith Search). Includes lock, unlock and trunk buttons.
Dead Coin Battery
The most common reason your 500 key fob doesn't function is a dead battery. Modern key fobs operate with a limited range of operation, and should be within some feet of the car to operate. 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, simply replace the battery of your coin cell (Part number CR2032) with a brand new one from a trusted brand like Panasonic, Duracell, or Energizer. They are available at your local hardware store or online.
You can test the coin-cell battery by pressing the buttons while you're standing close to your Fiat 500. The car should blink its parking lights, and the key fob will operate the lock and unlock switches.
If your fob's key isn't working after replacing the battery, there may be water damage that is preventing it from communicating with the module in your vehicle. Water damage can occur in a number of ways, ranging from small splashes to submerging the fob in salt water at the beach. If you suspect that your fob has been exposed to water, put it in a bag of rice to draw out the moisture. If this isn't working, you'll need to have your fob replaced by an auto locksmith or dealer.
Water Damage
Damage to the water supply can occur if you immerse the fob into the ocean, or wash it in a machine. Saltwater is especially dangerous to the fob's circuit board that can cause it to short out and eventually end up dying. It's not a good idea to get the fob wet but don't give up when you accidentally drop it in the water or don't take it out of your pants pocket.
First, remove the battery from the fob. Clean the electronic chip with isopropyl ethanol or a similar product and dry it thoroughly before replacing the battery. Check the fob again to check if it's working. If the fob doesn't work, it may have to be programmed again. This is usually handled by an auto locksmith or dealer.
If the key you have is older and not programmed to work with your vehicle then you'll need to replace it completely. A professional locksmith for cars can complete this simple process. The locksmith will require the key to be cut to match the car's ignition. They'll also have to reprogram the fob in your car's system. This is a quick and cost-effective process that can be completed within the same day.
Receiver Module Issues
One of the simplest reasons your 500 key fob could stop functioning is that 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. It is possible to fix this by moving the remote closer to your vehicle until it responds.
If you've replaced your coin battery (commonly known as"button" or "button" or "watch") and your fob still won't work, it could have an internal circuit board issue. In the majority of cases, reprogramming your fob can resolve the problem. You can find instructions on how to do this for the majority of automobiles by searching YouTube or checking out the owner's manual.
It's possible that you need to replace the metal clips that hold the coin battery. If they lose tension, it can stop your coin battery from being properly seated and cause your remote to malfunction.
In rare instances it is possible that the fob will become disconnected from your vehicle due to software problems or hardware issues. This issue can be fixed by visiting your local auto-locksmith or dealer to reprogram your key fob. In g28carkeys.co.uk , they may need to reinstall the program in your body control module as well.
Interference
Interference can also cause the key fob to be unable to receive or transmit a signal. This could happen if the key fob is located near radio transmitters (cell phones or radar detectors) or another source of electromagnetic radiation. The key fob might not function because of a problem with the buttons water damage or damage to the internal chips.
If the key fob has suddenly stopped working, suddenly and you've tried every option at home to fix it e.g. You could have a malfunctioning 500 receiver module if you've tried replacing the battery, reprogramming, and using an alternative key fob. The receiver module, which is located under the dashboard, picks up radio frequency signals from your key fob. It converts the signals into electronic commands that are then interpreted by the vehicle.
Fortunately, there's an easy method to reset every single system on board in your 500 and include the key fob. Disconnect the battery for 15 minutes by taking off first the negative cable and then the positive cable. Then, reconnect the battery. This will erase any remaining electricity, and allow you to restart the computer in your car. This can help get your key fob to work again. If the issue continues it is recommended that you consult an expert certified technician. They will be able to identify the root cause of your issue.
