How to Find a Fiat 500 Spare Key
Fiat's 500 is something of an iconic car since its relaunch in 2007. The company is now kicking off a new campaign to different engines with a mild-hybrid version.
The replacement of the key fob batteries on the Fiat 500 are simple and affordable. The Fiat main dealer will supply the key within 10 days.
Fault Diagnosis
The key fob houses an electronic chip which communicates with your Fiat's immobiliser system to ensure that only authorised vehicles are able to start engines. If the transponder inside your key fob has been damaged, it will not be capable of connecting to the immobiliser, which means your vehicle will not start.
It is possible to repair keys that have been damaged, so long as the chip isn't physically harmed. A professional locksmith will utilize dealer-standard technologies to repair it quickly.
Utilizing an OBD scanner, it is possible to check if the fob is still communicating with the receiver module. It's a quick and simple procedure that will provide a first indication of the issue. If the OBD scanner indicates that there is no communication between the receiver and transmitter modules, it might be necessary for the fob's transmitting module to be replaced. This is a costly option and should be left to a locksmith.
Dead Coin Battery
The most common reason for an unresponsive key fob is a dead coin battery. It's simple fix that takes only a few minutes. First, make sure that the key fob is in the range of your vehicle. Press the "Lock" and "Unlock" buttons to check whether they respond.
If the key fob is not in range, it might not respond at all or only intermittently. This could be an indication that the circuit board inside the key fob has failed. In this situation you'll need to refer to the manual of the owner for instructions on how to reprogram the key fob.
You can replace the battery by removing the mechanical latch on the back of the fob (see the image below). Then, gently pry the edge of the battery holder away from the switch to remove the old coin-cell battery. Install a brand new 3-volt #CR2032 battery into the fob with the "+ side" facing the cover at the rear and the " side" looking down towards the rubber buttons.
Water Damage
Although the key fob comes with rubber seals that keep water out of the electronic chip inside, it's not waterproof. The key fob should be fine in the event of a splash of rain or water from a wash cycle but submerging it in water from the ocean or pool is not recommended.
The key fob will need to be reprogrammed if it is exposed to water. This can be done using the instructions found in the owner's manual or by taking it to an expert auto locksmith or a Fiat dealer.
A fob that is out of range may stop working. The range of the fob's range is usually around 30 feet. If they are far away from the car, then it will not recognize them. The first step is to get closer to your car. If it doesn't work, the battery for your key fob may require replacement. You can find battery replacement instructions for a variety of automobiles on YouTube or in the owner's manual. This is the perfect time to think about buying a new key fob in case yours is starting to look scruffy and scratched.
Faulty Receiver Module
In more modern models of Fiat cars you don't need a physical key to open or start the car. These cars have keys that send a wireless signal to the car that turns off and turn on the engine. If you've lost your key fob, a locksmith can replace it for you. Leave this job to the experts and save time and money. They can also program the new key for your Fiat.
When you are getting an additional key for your Fiat vehicle, you'll have to provide the locksmith with details about the car over the phone. For instance, you'll need to provide the year of manufacture of your vehicle and the name of the model. This information is important because locksmiths require it to ensure that the new key is compatible with the locks in place.
Not all locksmiths can create replacement keys for Fiat automobiles. Find a locksmith with an established track record and expertise in the field. You can rest assured that the key will work for your vehicle, and you won't waste money.
Keys that are not paired
The most frequent reason for a key fob not working is a dead coin-cell battery. The key fob has metallic clips which hold the battery in place and are part of the circuit. If these clips wear out or loose, they can cause contact issues and loss of power. Replace the battery with one of the same size, voltage, and specifications, or a spare.
If G28 has been submerged in water, it is vital to dry it before re-inserting it. Using isopropyl alcohol or electronic cleaner is an effective method to do this. It is also recommended that you remove the battery and clean the circuit board and replace it before replacing.
If you're not able to locate a spare key, the best choice is to call the locksmith. Locksmiths who are certified to reprogram Fiat transponder keys can do this without needing to look at the original keys. This is a cheaper and faster solution than waiting for a genuine Fiat key to arrive from Italy. A professional locksmith will have all the tools and equipment needed to replace your key as quickly as is feasible.
