How to Find a Fiat 500 Spare Key
Fiat's classic Fiat 500 has become an icon since its relaunch in 2007. TheKeyLab is now planning an even bigger attack on different powertrains with the launch of a mild hybrid version.
Replacing the battery in the key fob on the Fiat 500 is straightforward and inexpensive. It takes about 10 days for the key to be delivered from the Fiat main dealer.
Fault Diagnosis
The key fob comes with an electronic chip that communicates with the Fiat immobiliser system. This makes sure that only authorized vehicles can start the car. If the transponder chip within your key fob is damaged, it won't be able to connect to the immobiliser unit, which means that your car won't be able to start.
The good news is that it's feasible to repair a damaged key fob, provided the chip is not physically damaged. A professional locksmith can assist with this, and they'll use dealer-standard technology to fix it quickly and efficiently.
With an OBD scanner, it is possible to verify if the fob is still communicating with the receiver module. This is a simple process, and it can provide initial indications of where the issue is. If the OBD scan tool indicates that communication between the transmitter and receiver modules is not occurring It may be necessary to replace the transmitter module of the fob. This is a costly solution and should be left to a locksmith.
Dead Coin Battery
A dead battery on a coin is the most frequent reason for the key fob to not function. It's an easy fix that takes about 15 minutes. Make sure the key fob can be seen by your vehicle. Then, try pressing the "Lock" or "Unlock" button to test if it responds.
If the key fob is out of range, it might not respond at all or only intermittently. This could be an indication of a damaged circuit board. It is recommended to consult the owner's manual for instructions on how you can reprogram the keyfob for this scenario.

Install a brand new 3-volt #CR2032 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
The key fob isn't waterproof even though it is fitted with rubber seals to keep water from entering the electronic chip. A splash of rain or washing cycle is likely to be acceptable but submerging the key fob in ocean or pool water will probably damage it.
The key fob will have to be reprogrammed if it is exposed to water. This can be accomplished by following instructions in your owner's manual or by taking it to a professional auto locksmith or an Fiat dealer.
A fob that is not in range may not function. The range of the fob's range is typically about 30 feet. If they are too far from the vehicle, it will not recognize the fob.

Keys that are not paired
The most frequent reason for a key-fob not functioning is a dead coin-cell battery. The key fob comes with metal clips that keep the battery in place and completes the circuit. When they become worn or loose, it can cause contact issues and lose power. Replace the battery with a new one with the same size, voltage, and specifications, or get a spare.
It is essential to dry out the key fob in case it was submerged into liquid. Utilizing isopropyl alcohol or an electronic cleaner is a suitable method to do this. It is also recommended that you remove the battery and clean the circuit board, and replace it prior to replacing.
