Starting Your Fiat

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.
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.

The Key Fobs used in Fiat models built after 2010 are sleek and rounded (see the image to the right). Slide the mechanical latch at the top of the back of the Fob to the side and pull the emergency key out with your free hand.
In 2023, the Fiat 500X will be hiding its keyhole behind a small cap in the handle recess (see image). The cap is easily removed with a fingernail, using the access hole shown to the right. Once removed the use the mechanical key in the keyhole to unlock the door, and you’ll be inside.
To remove the emergency (mechanical) key from the key fob in new Wagoneer models look for a chrome button on the side, as denoted by the bottom arrow. Push it and pull on the key ring end, and the mechanical key is removed.
New Wagoneer and Grand Wagoneer models have their key holes hiding behind the driver’s door handle, as can be seen in the image to the right. It is exposed when the door handle is pulled to the open position. So, simply pull the door handle out as far as possible. Insert the mechanical key (it may be awkward to get at) and turn it to unlock. Remove the key blade and release the handle. Pull the handle once again and you are in the car.
