How to Find a Fiat 500 Spare Key
Fiat's classic Fiat 500 has become a symbol since its relaunched in 2007. Now the company has kicked off a new campaign to different powertrains by launching a mild-hybrid version.
The replacement of the key fob batteries on the Fiat 500 are simple and inexpensive. The Fiat main dealer will provide the key within 10 days.
Fault Diagnosis
The key fob has an electronic chip that communicates with the Fiat immobiliser system. This ensures that only cars with a valid license are able to start the car. If the transponder chip in your key fob is damaged, it won't be able to link up to the immobiliser unit which means that your car won't start.
It is possible to repair keys that have been damaged, so long that the chip isn't physically damaged. A professional locksmith can help with this, and they'll employ the latest technology from dealers to repair it quickly and efficiently.
Using an OBD scanner, it is possible to verify if the fob is still communicating with the receiver module. This is a quick and simple process that could give you an initial indication of the problem. If the OBD scan tool shows that communication between the receiver and transmitter modules isn't happening it could be necessary to replace the transmitter module on the fob. This is a costly option and should be left to a locksmith.
Dead Coin Battery
The most frequent reason for an unresponsive key fob is a dead battery. It's an easy fix that takes about 15 minutes. First, ensure that fiat 500 duplicate key is within 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 it may only function intermittently. This could be an indication that the circuit board in the key fob has gone bad. In this situation, you'll need to consult the owner's manual to find out instructions on how to reprogram the key fob.
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 lift the edges of the battery holder near the switch and then remove the old battery. Put a brand new #CR2032 3-volt battery into the fob with the "+ side" facing the cover on the rear and the " side" directed towards the rubber buttons.
Water Damage
Although the key fob has rubber seals that keep water from the electronic chip inside, it's not waterproof. The key fob should be able to withstand the rain or water from a washing cycle, however, submerging it in ocean or pool waters is not recommended.
The key fob needs to be reprogrammed when it is exposed to water. You can follow the instructions in your owner’s manual, or bring it to a professional locksmith or Fiat dealer.
Another common reason a fob may stop working is because it's out of reach of your vehicle. Key fobs typically have a range of 30 feet and if they're far away from your vehicle, it won't be able to recognize them. For starters, try moving closer to your vehicle. If this fails, you may require replacing the key fob. You can find battery replacement instructions for the majority of vehicles on YouTube or in the owner's manual. If your key fob appears scuffed and dented, it's time to replace it.
Faulty Receiver Module
In the more modern versions of Fiat cars it is not necessary to have a physical key to open or start the car. The cars have a remote control that transmits an electronic message to the car in order to switch the engine on and off. If you've broken your key fob, a locksmith will replace it for you. You can save yourself time and money by entrusting the job to the experts. They can also program the new key for your Fiat.
If you're looking to purchase an additional key for your Fiat vehicle, you'll need to provide the locksmith with information about the car over the phone. You will need to give the locksmith details about your car, like the year it was produced and the model. This is crucial because locksmiths require it to ensure that the new key works with the existing locks.
You must be aware that not all locksmiths are able to make replacement keys for Fiat vehicles. You need to look for one with a good reputation and experience in this area. This will allow you to be certain that the new key will work with your car and you won't be wasting money.
Keys that are not paired
The most frequent reason for a key fob not functioning is a dead coin-cell battery. The key fob has metallic clips that hold the battery in place, and completes the circuit. When they become worn or loose, it could cause contact issues and lose power. Replace the battery by a new, identical one.
It is important to dry out the key fob when it was submerged in liquid. This can be accomplished by using isopropyl or an electronic cleaner. It is also recommended that you remove the battery and clean the circuit board and replace it prior to replacing.
Contacting locksmiths is the best choice if you're unable to find a spare. A locksmith with the ability to reprogram Fiat transponder keys can do it without having to see the original keys. This is a quicker and cheaper solution instead of waiting for an original Fiat key from Italy to arrive. A professional locksmith will also have the tools and equipment necessary to complete a replacement in as little time as possible.
