Fiat models built after 2010 use the rounded key fob shown in the image. Place the “nose” side (side opposite of the mechanical key – its very sensitive to this) of the Key Fob against the Start / Stop ignition button (right) and push to operate the ignition switch.

Do NOT try to remove this button! We have actually seen an owners manual citing an older key and button. Do NOT remove the flush button. Simply press the button with the nose of the key fob!

We have a video here that will help.

The 500e, e for electric, introduced in 2024, uses a new back up start method. The key fob is dropped into the cup holder between the front seats. The buttons should be facing up (right). The right spot will be marked by the image of a key with lines radiating from it.

Once the fob is in place, start the car as normal by pressing the Start / Stop button while stepping on the brake.

Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.

Models examined include the 500, 500x, 500e and Spider. Model years 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, and 2026.
