How to Find a Fiat 500 Spare Key

Fiat's classic 500 has become something of an icon since its relaunch in 2007. Now the company has kicked into a larger offensive toward different engines with a mild-hybrid version.

Replacing the key fob's battery on a Fiat 500 is straightforward and inexpensive. The Fiat main dealer will deliver the key in approximately 10 days.

Diagnostics of a fault

The key fob houses an electronic chip which communicates with your fiat 500 keys's immobiliser system to ensure that only authorized cars are able to start the engine. If the transponder contained in your key fob has been damaged the chip will not be connected to the immobiliser, which means that your car will not start.

The good news is that it's possible to repair a damaged or broken key fob, provided the chip is not physically damaged. A professional locksmith will utilize standard technologies from dealers to repair the chip quickly.

With an OBD scanner, it's possible to check if the fob is still communicating with the receiver module. It's a quick and simple process that can give you an initial indication of the problem. If the OBD scan tool indicates that communication between the transmitter and receiver modules isn't working it could be necessary to replace the fob's transmitter module. This is a costly option and should be left to a locksmith.

Dead Coin Battery

A dead battery for the coin is the most frequent reason for the key fob not to function. It's an easy fix that takes minutes. Ensure that the key fob is visible to your vehicle. Press the "Lock" and "Unlock" buttons to check whether they respond.

The key fob might not function at all, or maybe only intermittently, if out of range. This could also be a sign that the circuit board in the key fob has failed. You'll have to refer to your owner's guide for instructions on how you can reprogram the keyfob in this situation.

You can change the battery by pulling off the mechanical latch that is on the back of the fob (see the image below). Then, gently pry out the the battery holder, close to the switch and remove the old coin cell battery. Then, insert a new volt battery into the fob assembly, with the "+" side facing towards the rear cover of the key fob, and the "side facing down towards the key fob with the " side facing downwards toward the buttons made of rubber.

Water Damage

Although the key fob has rubber seals that keep water out of the chip, it is not waterproof. A splash of rain or washing cycle is likely to be okay but submerging the key fob in pool or ocean water could cause damage to it.

If the key fob is exposed to water and stops working the device will need to be reset. This process can be done by following the instructions in the owner's manual or by bringing it to an auto locksmith professional or a Fiat dealer.

A fob that is out of range may stop working. Key fobs generally have a range of approximately 30 feet, and if they're too far from the vehicle, it won't be able to recognize them. To begin with, try moving closer to your car. If this isn't working, you might need to replace your key fob. There are battery replacement instructions for a variety of automobiles on YouTube or in the owner's manual. This is the perfect time to consider getting a replacement key fob in case yours is beginning to look shabby and scratched.

Faulty Receiver Module

Modern Fiat models do not require the use of a key to start or open the car. The cars utilize keys that send an electrical signal to the car that turns on and off the engine. If you've broken your key fob, a locksmith can replace it for you. You can leave this task to the experts and save time and money. They can also program a new key for your Fiat.

You'll need to give the locksmith a few details over the phone when you need a replacement Fiat key. For instance, you'll have to provide the year of production for your vehicle and the name of the model. This is vital as locksmiths need it to ensure that the new key works with the locks in place.

You should be aware that not all locksmiths are able to create replacement keys for Fiat vehicles. Find a locksmith with an excellent track record and experience in the field. This means you can be sure that the new key will work with your vehicle and you will not waste money.

Unpaired Key

The most common reason for a key fob that isn't working is a dead coin-cell battery. The key fob has metal clips that hold the battery in place and complete the circuit. If these clips wear out or loose, it can cause contact issues and loss of power. Replace the battery with the same one, but with a different design.

If the key fob was submerged in water, it is crucial to dry it before inserting it back into the device. Utilizing isopropyl alcohol or an electronic cleaner is a great way to do this. It is also recommended to remove the battery and clean the circuit board prior to replacing it.

Contacting locksmiths is the best option in case you're unable to find a spare. A locksmith who is certified to reprogram Fiat transponder keys is able to do this without having to see the original keys. This is a far cheaper and quicker solution than waiting for an authentic Fiat key to arrive from Italy. A professional locksmith is equipped with all the tools and equipment required to replace your key as fast as is possible.
