If the button cell battery in the key fob of Fiesta is replaced incorrectly or a battery is unsuitable, it can damage the vehicle key. Only replace drained batteries with new batteries in the same voltage, size, and specification. Make sure the battery is facing in the right direction when inserting it. The system may need to be restarted. To restart your system, shut down the engine, open and close the door, and then lock the door and wait for 2-3 minutes. Make sure that your SYNC 3 screen is black and the lighted USB port is off. SYNC 3 is not able to download my phonebook. This is a cell phone-dependent feature. 57 people found this helpful.
