Remotes
The remote controls on Fiat automobiles look a lot like keys, however they have an IR (infrared) LED at the end. The LED transmits an electronic signal to the device which allows the vehicle to open or start when the button is pressed.

Keyless Entry
If you have a keyless entry system on your Fiat 500, you can secure and unlock the car from anywhere with a push of a button. This technology is becoming increasingly popular in all kinds of vehicles which adds convenience and security to the usage of your vehicle.
If your remote keyless entry system fails to work look to see whether the battery in the fob has gone dead. Replace the battery with a newer one with the same voltage size, type, and capacity as the original if it's depleted. You should also ensure that the battery's contacts are clean and free of corrosion or dust.
The rubber seals on the key fob protect the chip from water. However long-term exposure to salty or soapy water may cause the chip to fail. If your key fob has been exposed to water, remove the battery and allow it to dry completely before putting it back into. You can also try cleaning the electronic chip using isopropyl alcohol or an electronic cleaner.
While some people may believe that keyless entry isn't as secure, the system is actually more secure than traditional systems because the code that unlocks your car is rolled up after every use. This means that even if hackers attempt to intercept the signal, they won't be able to gain permanent access to your car.
Transponders

Fiat utilizes a crypto-key transponder system, which means that the keys/transponders must be precoded by the Body Control Module before they are "programmed" within the BCM. This is the reason a blank unwritten key cannot be programmed, because the BCM must read and write the secret key to the transponder & lock it. This is known as the process of cloning.
