Reasons Your Fiat 500 Key Fob Won't Work
A key fob from Fiat 500 is a handy way to unlock the doors and get started the car. There are many reasons why the fob won't work. This includes a dead coin-battery or water damage, receiver modules issues, and interference.
This listing is for an NEW replacement Fiat Flip Key Remote - like the Ilco brand that needs to be programmed professionally by a local locksmith (click here for Locksmith Search). This remote 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 have a very limited range of operation, and must be within just a few feet of the vehicle in order to function. If you're far from your vehicle when you press the key fob button, the car will not respond, and will display the "Key Fob Not Detected" message in the instrument cluster.
If this happens then replace the battery for your coin-cell (Part Number CR2032) by a brand new one of a trusted brand like Panasonic Duracell or Energizer. You can find them at the local hardware store or online.
You can test the battery of your coin-cell by pressing the buttons while standing near your Fiat 500. fiat 500 key fob replacement parking lights should flash and the key fob should operate the lock and unlock switches.
If your key fob still isn't working after replacing the battery, it might be water damage that hinders it from connecting to the module in your vehicle. Water damage can happen in a number of ways, ranging from an accidental splash to submerging the fob salt water at the beach. If you suspect your fob was exposed to water, you can try placing it in a dry rice bag to draw the moisture back out. If this doesn't work, you will have to get your fob reset by an auto locksmith or a dealer.
Water Damage
While the fob has some rubber seals to keep water from the electronic chip inside the device, submerging it into the ocean or washing it in a machine can cause water damage. Saltwater poses a particular risk to the circuit board of the fob that can cause it to short out and eventually die. It's not the best idea to let the fob get wet however, don't give it up in the event that you accidentally drop it in water, or fail to remove it from your pants pocket.

The locksmith will have to cut the key to match the ignition of your vehicle. They'll also have to reprogram the fob to your vehicle's system.

Receiver Module Issues
One of the simplest reasons your 500 key fob may stop working is because it's out of range. The remote usually has an area of 30 feet or less and if it's far from your vehicle, it won't respond to your commands. You can easily solve this problem by moving the remote closer to your vehicle until it responds.
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 issue. In most cases, reprogramming the fob will fix the issue. You can find the instructions for most vehicles on YouTube or in the owner's guide.
It is possible to replace the clips made of metal that hold the coin batteries in place. If they loose tension, it could hinder the coin battery from sitting properly and can result in the malfunction of your remote.

This can be a major trouble, but you could usually fix it by visiting an auto locksmith to have them reprogram your fob for you.

Interference
Interference can also cause the key fob to not be able to receive or transmit the signal. This could happen if the key fob is close to the radio transmitter (cell phones, radar detectors) or any other source of electromagnetic radiation. The key fob may not function 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 have tried everything at home to fix it (e.g. battery replacement, reprogramming and using the spare key fob, it could have a defective receiver module on your 500. The receiver module, which is located under the dashboard, is able to pick up radio frequency signals from your key fob. It converts the signals into electronic commands, which are then read by the vehicle.
Fortunately, there's an easy way to reset all on-board systems in your 500 device, including the key fob. Disconnect the battery for 15 minutes by removing first the negative cable and then the positive cable. Then, reconnect the battery. This will clear any residual electricity, and allow you to restart the computer of your car. This can help get your key fob to work again. If the problem persists you should seek out an expert technician. They can determine the root of your problems.
