Reasons Your Fiat 500 Key Fob Won’t Work
A key fob with the fiat 500 number is a great way to unlock the doors and start the car. However, there are numerous reasons the fob could stop working. This includes a dead battery, water damage, issues with the receiver module, and interference.
This listing is for an NEW replacement fiat spare key Flip Key Remote that is similar to the Ilco brand. It has to be professionally programmed (click here to search for local locksmiths in the automotive industry). Includes lock, unlock and trunk buttons.
Dead Coin Battery
A dead battery is the most common reason for your 500 key fob not working. Modern key fobs only have a limited range of operation and must be within only a few inches from the vehicle in order to function. If you’re not close to your vehicle and press the key fob button, the car won’t be able to respond, and will display a “Key Fob Not Detected” message in the instrument cluster.
If this happens, replace the battery in the coin cell (Part number CR2032) by a new one from a reliable brand such as Panasonic, Duracell, or Energizer. You can find them at the local hardware store or on the internet.
You can test the battery of your coin-cell by pressing the buttons while you’re standing close to your fiat Spare Key 500. The car will blink its parking lights and the key fob will operate the lock and unlock switches.
If the fob’s key doesn’t function after replacing the battery, it may have water damage that stops it from connecting to the receiver module inside your car. Water damage can happen in a variety of ways, such as a simple splash or submerging the key fob into saltwater at the beach. If you suspect your fob was exposed to water, put it in a dry rice bag to pull the moisture back out. If this doesn’t work, you will need to have the fob reset by an auto locksmith or dealer.
Water Damage
Damage to the water supply can occur if you immerse the fob in the ocean or wash it in a washing machine. Saltwater poses a particular risk 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 submerge the fob in water however, but don’t give it up when you accidentally drop it in water or forget to remove it from your pants pocket.
First take the battery off the fob. Before replacing the battery, clean the electronic chip using isopropyl or similar products. Next test the fob to see if it works. If the fob doesn’t work then it might need to be programmed again. This is usually done by an auto locksmith or dealer.
If the key you have is older and not programmed for your vehicle, you will need to replace it completely. A professional automotive locksmith can complete this simple process. The locksmith will have to cut the key to match the ignition in your vehicle. They’ll also need to reprogram the fob to the car’s system. This is a fast and cost-effective process that can be completed in 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 30 feet of range or less, and if it’s too far from your lost car key fiat, it won’t respond to your commands. You can easily solve this issue by moving the remote closer to your car until it responds.
If your fob doesn’t work after you replace the battery inside the coin, which is also known as a “button”, “watch” or “button” or “button”, it could be due to a problem with the internal circuit board. Reprogramming the fob usually resolves this issue. There are instructions on how to do this for the majority of vehicles by searching YouTube or consulting the owner’s manual.
It is possible to replace the clips made of metal that hold the coin batteries in the correct position. If they loose tension it can prevent the battery from sitting properly and cause your remote to malfunction.
In rare instances, the fob could be out of connection with your vehicle as a result due to hardware or software issues. You can fix this issue by visiting your local auto-locksmith or dealer to reprogram your key fob. In certain instances they may have to reinstall the program in your body control module, as well.
Interference
Interference can also cause the key fob to not receive or transmit an signal. This is possible when the key fob is close to a radio transmitter (cell phones, radar detectors) or another source of electromagnetic radiation. The key fob might not work due to a poor connection with the buttons, water damage or damage to the internal chips.
If your key fob suddenly stopped working, or you’ve tried everything at home to fix it (e.g. replacing the battery, reprogramming, and using the spare key fob, you may have a faulty receiver module on your 500. The receiver module is located under the dash, and it picks up the radio frequency signals from the key fob. It converts the signals into electronic commands that are then translated by the vehicle.
There is a simple way to reset the 500’s in-board system, including the keyfob. Disconnect the battery 12 volt for about 15 minutes, by removing the negative cable and then the positive cable. Reconnect the battery. This will eliminate any remaining electricity, and restart the computer in your car. This could help you get your key fob to function again. If the issue continues, you should seek the advice of an expert technician. They can determine the exact cause of your problem.
