How to Find a Fiat 500 Spare Key

Fiat's classic Fiat 500 has become a cult classic since its relaunch in 2007. Now the company has kicked off a larger campaign towards different powertrains by launching a mild-hybrid version.

Replacing the battery for the key fob on a Fiat 500 is straightforward and cheap. It takes around 10 days for the key to be delivered from the Fiat main dealer.

Fault Diagnosis

The key fob houses an electronic chip which communicates with your Fiat's immobiliser system to ensure that only authorized vehicles can start the engine. If the transponder contained in the key fob has been damaged or damaged, it will not be connected to the immobiliser, which means that your car won't start.

The good part is that it's attainable to repair a damaged key fob, as long as the chip isn't physically damaged. A professional locksmith will employ the same technology used by dealers to repair it swiftly.

Utilizing an OBD scanner, it is possible to check if the fob is still communicating with the receiver module. This is a fast and simple procedure that will give you an initial indication of the problem. If the OBD scanner says there is no communication between the receiver and transmitter modules, it may be necessary for the fob's transmitter module to be replaced. This is a costly option and should be left to locksmiths.

Dead Coin Battery

The most common reason for a key fob not working is a dead coin battery. This is a simple fix that only takes about a couple of minutes. Make sure the key fob is visible to your vehicle. Press the "Lock" and "Unlock" buttons to check whether they respond.

The key fob could not function in any way, or just occasionally, if it's out of range. This could also be a sign that the circuit board inside the key fob has failed. It is recommended to consult the owner's manual for instructions on how you can reprogram the keyfob in this case.

You can replace the battery by taking off the mechanical latch on the back of the fob (see the image below). Then, gently lift the the battery holder, close to the switch and then remove the old battery. Then, place a new 3 volt battery # CR2032 into the fob assembly with the "+" side facing toward the cover on the rear of the key fob, and the "+" side facing down towards the rubber buttons.

Water Damage

The key fob is not waterproof even though it's got rubber seals to keep water from getting inside the electronic chip. The key fob should be fine in the event of water from a shower or water from a wash cycle, however, submerging it into water from the ocean or pool is not recommended.

The key fob will have to be reprogrammed if the device is exposed to water. This process can be done using the instructions found in the owner's guide or by taking it to an auto locksmith professional or an Fiat dealer.

A fob that's not in range could stop working. The range of the fob's range is typically around 30 feet. If they are too far away from your car, it may not recognize the fob. In the beginning, try getting closer to your vehicle. If this isn't working, you might need to replace the key fob. There are battery replacement instructions for most vehicles on YouTube or in the owner's manual. If your key fob is looking damaged and scratched, it's time to replace it.

Faulty Receiver Module

Modern models of fiat keys do not require a physical key in order to start or open the car. These cars use a remote control that transmits an wireless message to the car in order to turn the engine on and off. If you've lost your key fob, a locksmith is able to replace it for you. You will save time and money by leaving the job to the experts. They can also program a brand new key for your Fiat.

You'll have to provide the locksmith with some details over the telephone when you want a spare Fiat key. For instance, you'll be required to mention the year of manufacture of your car, along with the name of the model. This is crucial because the locksmith will need this information to make sure that the new key works with the existing locks.

You should be aware that not all locksmiths can make replacement keys for Fiat vehicles. Find a locksmith that has an excellent track record and experience in the field. You can be sure that the key will work with your vehicle and you won't waste money.

Unpaired Key

The most frequent reason for a key-fob not working is a dead coin-cell battery. The key fob has metal clips that secure the battery in place and complete the circuit. When these become worn or loose, they can cause contact problems and no power. Replace the battery with one of the same voltage, size and specifications, or a spare.

If the key fob was submerged in water, it's crucial to dry it before re-inserting it. This can be accomplished using isopropyl or electronic cleaner. It is also recommended to take out the battery and clean the circuit board and replace it before replacing.

Contacting locksmiths is the best choice if you're unable to find a spare. A locksmith who is experienced can reprogram a Fiat transponder key, without needing to see the original keys. This is a cheaper and faster option than waiting for a genuine Fiat key to arrive from Italy. A professional locksmith will have all the tools and equipment required to complete a replacement fiat key as quickly as possible.
