How to Find a Fiat 500 Spare Key

Fiat's iconic Fiat 500 has become a cult classic since its relaunch in 2007. The company is now planning an aggressive campaign to other powertrains, including a 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 in about 10 days.

Diagnosis of a Fault

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 chip in your key fob is damaged, it won't be able to connect to the immobiliser unit which means that your car won't start.

It is possible to repair the key fob that has been broken, as long that the chip isn't physically damaged. A professional locksmith can assist with this issue, and they'll use dealer-standard technology to fix it quickly and efficiently.

It is possible to use an OBD scanner to check whether your fob is communicating with the receiver module. This is a fast and easy process that can provide a first indication of the problem. If the OBD scanner shows that there is no communication between the receiver and transmitter modules, it might be required for the fob's transmitter module to be replaced. This can be a pricey option, and it's best left to a professional locksmith.

Dead Coin Battery

A dead battery on a coin is the most frequent reason for the key fob not to work. This is a simple fix that only takes about a couple of minutes. First, ensure that the key fob is in range of your vehicle. Press the "Lock" and "Unlock" buttons to see whether they respond.

The key fob may not function in any way, or just intermittently, in the event that it is out of range. This could also be an indication that the circuit board in the key fob has failed. In this scenario you'll need to check the owner's manual to find out instructions on how to reprogram the key fob.

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

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 may be able to withstand the splash of rain or water from a wash cycle however, submerging the device in ocean or pool waters is not recommended.

If the key fob is exposed to water and stops working it will have to be reset. This can be accomplished by following the directions in your owner's manual or by taking it to an auto locksmith professional or an fiat 500 keys dealer.

A fob that is out of range may stop working. Key fobs generally have a range of around 30 feet and if they're far away from the car, they won't recognize them. In the beginning, try getting closer to your vehicle. If it doesn't work, the key fob battery might need to be replaced. You can find battery replacement instructions for all automobiles on YouTube or in the owner's manual. This is the perfect time to think about purchasing a replacement key fob if yours is beginning to look worn and dented.

Faulty Receiver Module

Modern Fiat models do not require the use of a key to start or open the car. The cars utilize the key fob which sends an electrical signal to the car that turns off and turn on the engine. Locksmiths can repair a broken key fob. You can save yourself time and money by delegating this job to professionals. They can also program a new key for your Fiat.

If you're getting an additional key for your Fiat vehicle, you'll have to provide the locksmith details about the car over the phone. You'll need to provide the locksmith information about your car, such as the year it was manufactured and the model. This is vital as the locksmith needs it to ensure that the new key is compatible with the existing locks.

It is important to note that not all locksmiths are able to make replacement keys for Fiat vehicles. Find a locksmith with an established track record and experience in the field. This means that you are sure that the new key will work with your car and you will not waste money.

Unpaired Key

The most frequent reason for a key fob not working is a dead coin cell battery. The key fob comes with metal clips that secure the battery in place and complete the circuit. When these become worn or loose, they could result in contact issues and then no power. Replace the battery with one of the same size, voltage and specifications, or get a spare.

It is important to dry out the key fob in case it has been submerged in liquid. This can be accomplished using isopropyl or an electronic cleaner. It is also advisable to remove the battery and clean the circuit board prior to replacing it.

Contacting locksmiths is the best option if you cannot find an alternative. A licensed locksmith can reprogram a Fiat transponder key without having to see your original keys. This is a much less expensive and faster solution than waiting for an authentic Fiat key to arrive from Italy. A professional locksmith will have all the necessary tools and equipment to replace your key as swiftly as possible.
