Keyless Entry With a keyless entry on your Fiat 500 you can lock or unlock the vehicle at the touch of the button. This technology is increasingly common in all types of cars and provides convenience and security to the operation of your vehicle. If your remote keyless entry system stops working, check 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. You should also ensure that the battery's contacts are free of dust or corrosion. The rubber seals on the key fob are designed to protect the chip from water. However, prolonged exposure to soapy water or salty water can cause the chip to fail. If your key fob has been exposed to water, you must remove the battery and let it dry completely before putting it back in. You can also try cleaning the electronic chip using isopropyl ethanol or electronic cleaner. While some people may believe that keyless entry is less secure, the system is actually more secure than other systems because the code used to unlock your car gets rolled up after every use. This means that hackers won't have the ability to gain permanent access to your vehicle, even when they intercept the signal. Transponders Fiat uses a crypto-key transponder system this means that keys/transponders need to be precoded by the Body Control Module before they are "programmed" in the BCM. This is why an unwritten key is not able to be programmed, because the BCM has to read & write the secret code to the transponder and then lock it. This process is referred to as the cloning.
