How to Find a Fiat 500 Spare Key

Fiat's iconic Fiat 500 has become a cult classic since its relaunched in 2007. The company is now launching an aggressive campaign to other powertrains by launching a mild hybrid version.

Replacing the key fob's battery on the Fiat 500 is straightforward and cost-effective. It takes about 10 days for the key to be delivered from the Fiat main dealer.

Diagnosis of a Fault

The key fob comes with an electronic chip which communicates with the Fiat immobiliser system. This ensures that only cars with a valid license can start the vehicle. If the transponder chip inside the key fob is damaged, it won't be able to connect to the immobiliser unit, and as a result, your car won't be able to start.

The good thing is that it's possible 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.

It's possible to use an OBD scanner to determine whether your device is communicating with the receiver module. This is a simple procedure, and it can provide initial indications of the source of the issue. If the OBD scanner says there is no communication between the receiver and transmitter modules, it may be necessary for the fob's transmitting module to be replaced. This is a cost-effective option and should be left to a locksmith.

Dead Coin Battery

A dead battery for the coin is the most common reason for the key fob to not function. This is an easy 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 if they respond.

If the key fob's signal is out of range, it may not respond at all or might only work intermittently. This could be an indication that the circuit board in the key fob is damaged. You'll need to refer to the owner's manual for instructions on how to reprogram the keyfob in this situation.

You can change the battery by taking off the mechanical latch on the back of the fob (see the image below). Then, gently pry the edge of battery holder away from the switch to release the old coin-cell battery. Then, place a new volt battery into the fob assembly, with the "+" side facing the rear cover of the key fob and the "--" side facing down toward the rubber buttons.

Water Damage

The key fob is not waterproof even though it's got rubber seals that stop water from getting into the electronic chip. A splash of water from rain or a wash cycle is likely to be okay but submerging it fob in pool or ocean water will probably damage it.

The key fob needs to be reprogrammed when it is exposed to water. This can be accomplished using the instructions found in the owner's manual or by taking it to a professional auto locksmith or an Fiat dealer.

Another reason that a fob might stop working is that it's not in distance from your car. Key fobs generally have a range of 30 feet and if they're far away from your car, it won't recognize them. The first step is to get closer to your car. If this isn't working, you might have to replace the key fob. You can find replacement battery instructions for the majority of vehicles on YouTube or in the owner's manual. If your key fob is looking rough and scratched, it's time to replace it.

Faulty Receiver Module

Modern models of Fiat do not require a physical key in order to start or open the car. These cars use a remote control that sends a wireless message to the car in order to switch the engine off and on. A locksmith can replace the damaged key fob. You can leave this task to the professionals and save time and money. They can also program a new key for your Fiat.

If you are looking for an extra key for your Fiat vehicle, you'll need to provide the locksmith with information about your car on the phone. For instance, you'll have to provide the year of production of your car as well as the model's name. This information is important because the locksmith needs it to ensure that the new key works with the existing locks.

You should be aware that not all locksmiths can make replacement keys for Fiat vehicles. It is important to choose one that has a good reputation and has experience in this field. You can be sure that the key will work with your car and you won't lose money.

Unpaired Key

The most common reason for a key fob not working is a dead coin cell battery. The key fob has metallic clips that secure the battery in place, and completes the circuit. If these clips wear out or loose, they can cause contact issues and lose power. Replace the battery with the same one, but with a different design.

It is important to dry out the key fob in case it has been submerged in liquid. Using isopropyl or electronic cleaner is a good method to accomplish this. It is also recommended to remove the battery and clean the circuit board, and replace it before replacing.

Contacting locksmiths is the best solution if you are unable to locate a spare. A professional locksmith can reprogram a Fiat transponder keys without having to look up your original keys. This is a speedier and cheaper option than waiting for an original fiat 500 key key from Italy to arrive.
