If your remote keyless entry system isn't working look to see whether the battery for the coin in the fob has died. If the battery has been drained, replace it with a fresh one with the same voltage, size, and type as the original. It is also important to ensure that the battery's contacts are free of corrosion or dust.
The rubber seals on the key fob guard the chip from water. However long-term exposure to salty or soapy water could cause the chip to fail. If your key fob has been exposed to water, take it out and let the battery dry completely before replacing it. You can also try cleaning the electronic chip with isopropyl alcohol, or an electronic cleaner.

While some people might believe that keyless entry isn't as secure, this system is actually more secure than other systems because the code used to unlock your car is rolled away after each use. This means that even if hackers do intercept the signal, they won't be able to gain permanent access to your car.
Transponders
Fiat uses a crypto key transponder system which means that the keys/transponders need to be precoded by the Body Control Module before they are "programmed" within the BCM. This is why an unwritten key is not able to be programmed, as the BCM has to read & write it's secret key to the transponder and then lock it. This is referred to as cloning.
