External electronic disturbance can "muffle" the interaction between the fob and the car. Typical sources include:
High-tension power lines.Cellular towers.Other electronic devices in the motorist's pocket (smartphones, RFID-blocking wallets).Cheap aftermarket USB chargers plugged into the vehicle's 12V socket.4. Faulty Door Handle Sensors
The sensors inside the door handles are exposed to the components. Wetness, road salt, and extreme temperature level cycles can cause the capacitive sensing units to stop working or the wiring utilizes within the door panels to rust.
5. Body Control Module (BCM) Glitches
The BCM serves as the "brain" for the keyless entry system. Software bugs or short-lived problems can cause the module to stop processing entry demands. Sometimes, a software application upgrade from a Fiat dealership is needed to rectify recognized communication errors.
