If the key fob was exposed to water, for example a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. The trick is to use the paper towel and soak it in isopropyl or electronic cleaner.
If the key fob is not working despite being not exposed to water it could be due to a malfunction in the receiver module or in the internal electronic chip. Reprogramming the keyfob using an OBDII scan could help in these instances.
Water Damage
There could be water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the fob completely dry prior to installing the battery.

Faulty Receiver Module
The key fob's chip is a chip that communicates with the car's system. If the chip is damaged, it cannot longer transmit and receive signals to the vehicle. This could be due to dropping the key fob or through exposure to water. If your key fob stopped functioning due to water exposure and you are unable fix the issue if you clean the chip with electronic cleaner or isopropyl ethanol.
However, if the key fob is still unable to not respond after cleaning it, it is likely that the component is damaged and must be replaced. A damaged receiver module may also cause the remote control key to stop functioning. This is usually due to electromagnetic interference.
A malfunctioning electronic chip
The chip that is embedded in the key fob is an essential component of the anti-theft systems in your car. It transmits a message the immobiliser in your car to determine that the key is valid. Your lost car key fiat will not start in the event that the chip is damaged.
A defective chip could be caused by interference from objects, bad weather or transmitters in the vicinity of your vehicle. In this instance an upgrade to the fob will be needed.

Modern fobs have rubber seals to keep out water. A splash of water or a light rain should be fine, but submerging them in salt water could damage the electronic chip.
The key fob houses the chip that connects to the vehicle's immobilizer system in order to begin it. The system utilizes the old red keys that were used in older vehicles, or the cryptocoding system used in the latest vehicles. If the chip is not working properly, it will need to be replaced.
Poor 12 Volt Battery
A defective battery can cause the key fob to work. When this happens the car's computer will not be able to recognize that the remote is within the vehicle.
Test the battery with an voltmeter prior to replacing it how to get a new fiat 500 key determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly the time is now to replace it.
Set an electrical load for a short time on the battery to determine its capacity. This will take away 1percent of the surface charges. Then, test the voltage again. The better the battery's capacity, the longer it can maintain its voltage. The ideal is to keep it at or near 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most common reason for the key fob to stop sending signals to cars. The battery is able to be replaced to resolve this issue. It is however important to choose a battery with the same voltage and size as the original.
Fobs aren't impervious to damage and can be damaged by a lot. The battery contacts and buttons could be damaged by rough handling.
Other objects or transmitters using the same frequency can disrupt a signal. A light control panel in your home, for instance, may interfere with key fobs that have the same bandwidth. This could cause interference with the fiat ducato remote key programming control in your car.
Problems with OBDII Scan Tool
There are many reasons why a scan tool could not function. Some are more complex than others.
Professional scan tools let mechanics to look over the car's network and run various self-tests. They can be huge time-savers, but they are also extremely expensive, and beyond the range of most DIYers.
If your OBD2 scan tool isn't turning on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If these are OK, it's likely that a fuse has been blown. This is one of the most frequent causes of failures in the scan tool. It is usually simple to fix the issue by replacing the blown fuse.
