Keyless Entry

You should also ensure that the battery's contacts are clean and free from dust or corrosion.

If your key fob is exposed to water, you must remove the battery and let it dry completely before putting it back into.

Transponders
Fiat utilizes a crypto-key transponder system which means that the keys and transponders have to be precoded by the Body Control Module before they are "programmed" in the BCM. This is why a blank unwritten key cannot be programmed, as the BCM has to read & write it's secret key to the transponder and then lock it. This is known as"cloning.
