How to Find a Fiat 500 Spare Key

Fiat's 500 is an icon since its relaunch in 2007. The company has since kicked off a new campaign to different powertrains with a mild-hybrid version.

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

Fault Diagnosis

The key fob houses an electronic chip that communicates with Fiat's immobiliser system to ensure that only authorized cars can start the engine. If the transponder contained in your key fob is damaged or damaged, it will not be in a position to connect to the immobiliser, which means that your car will not start.

The good part is that it's attainable to repair a damaged or broken key fob, as long as the chip is not physically damaged. A professional locksmith will use standard techniques used by dealers to repair it quickly.

With an OBD scanner, it's possible to determine if your fob is still communicating with the receiver module. This is a simple procedure that can give an initial indication of where the issue is. If the OBD scan tool reports that communication between the receiver and transmitter modules is not occurring It may be necessary to replace the transmitter module on the fob. This is a cost-effective option and should be left to locksmiths.

Dead Coin Battery

The most common reason for a key fob that isn't working is a dead battery. It's simple fix that takes only a few minutes. Ensure that the key fob is recognized by your vehicle. Press the "Lock" and "Unlock" buttons to determine whether they respond.

If the key fob isn't in range, it may not be responsive at all, or it may only function intermittently. This could be an indication that the circuit board in 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 situation.

The mechanical latch can be removed from the back of the key fob. (See the image below). Then, gently lift the the battery holder near the switch, and remove the old coin cell battery. Then, put a new 3 volt battery # CR2032 into the fob assembly with the "+" side facing towards the rear cover of the key fob and the "+" side facing downwards towards the buttons made of rubber.

Water Damage

Although the key fob comes with rubber seals that keep water out of the chip, it is not waterproof. A splash of water from rain or a wash cycle is likely to be fine but submerging the key fob in ocean or pool water could cause damage to it.

If the key fob is exposed to water and ceases to function it will have to be reprogrammed. This process can be done by following the directions in the owner's manual or by taking it to an expert auto locksmith or a Fiat dealer.

Another reason why a fob can stop working is if it's out of range from your car. Key fobs typically have a range of about 30 feet, and if they're too far from the vehicle, it won't be able to recognize them. For starters, try moving closer to your vehicle. If you're not able to get it working, the battery for your key fob may require replacement. You can find information on how to replace the battery in most vehicles on YouTube or by consulting the owner's guide. This is a great time to think about buying a new key fob if the one you have is beginning to look worn and scratched.

Faulty Receiver Module

Modern Fiat models do not require an actual key to start or open the car. The cars have a remote control that transmits an electronic message to the car to turn the engine off and on. Locksmiths can repair the damaged keyfob. Leave this job to the professionals and save time and money. They can also create a new key for your fiat 500 key fob replacement.

If you are looking for an additional key for your Fiat, you will need to provide the locksmith with some details about the car over the phone. For instance, you will be required to mention the year of manufacture of your car, along with the model's name. This is vital as locksmiths need it to ensure that the new key is compatible with the locks in place.

Not all locksmiths can make replacement keys for Fiat automobiles. You must choose one that has a good reputation and experience in this field. You can rest assured that the key will work on your car and you won't lose money.

Keys that are not paired

The most common reason for a key fob not working is a dead coin cell battery. The key fob comes with metal clips which hold the battery in place, and completes the circuit. When they wear out or loose, they can cause contact problems and no power. Replace the battery with a fresh one of the same voltage, size and specification, or use a spare.

It is important to dry out the key fob if it has been submerged in liquid. This can be accomplished with isopropyl or an electronic cleaner. It is also recommended to take the battery off and clean the circuit board prior to replacing it.

Contacting a locksmith is the best option in case you can't find an extra. A locksmith with the ability to reprogram Fiat transponder keys is able to do this without the need for original keys. This is a quicker and cheaper option than waiting for a genuine Fiat key from Italy to arrive. A professional locksmith has all the tools and equipment to replace your keys as quickly as they can.
