You need this when the 12 volt battery has died and the doors will not unlock. On a gas Fusion the battery is under the hood. On the Fusion Hybrid and Energi the 12 volt battery is in the trunk, so you power the car through the jump terminals under the hood and then open the trunk electrically.

How to open a door Ford: dead battery

1. There is a release switch on the remote’s back. Open the smart key shell to access the emergency key.
2. Use the metal blade to remove the driver’s door handle cover. Insert the metal key into the hole in the bottom of the driver’s door handle, then pull towards the back.
3. Once you slide over the cover, you can see the keyhole.
4. Insert the key into the door lock and turn towards the back of the car to unlock your Ford. If the key won’t go in or turn, spray penetrating oil on the keyhole and try again.

If your metal key doesn’t unlock the driver’s door, try inserting the key in and out a few times. If that doesn’t work, spray penetrating oil in the keyhole and retry.

How to open a Ford Fusion trunk: Dead Battery

We often get asked how to open a Ford Fusion hybrid trunk if the car battery is dead.

To open the trunk of a Ford Fusion with a dead battery, manually open the driver’s door and the hood as outlined above. Then, locate the jump-start terminals under the hood to power up the vehicle and open the trunk by pressing the button on the dashboard or keyfob.

Follow these step-by-step instructions when opening Ford’s trunk if your car has a dead battery.

1. Remove the metal key from the keyfob. All smart keyfobs have a metal key inside that can be used to unlock the driver’s door.
2. Remove the cap on the driver’s door and unlock the door.
3. Pull the hood release and open the hood.
4. Locate the battery jump-start terminals in the engine bay. Look for a red plastic cover in front of the driver’s side.  That is the positive terminal.   A ground bolt is sticking out of the shock tower for the negative. Connect a jump starter or a battery charger at these terminals to power up the vehicle.
5. Press unlock on the keyfob or the trunk release button on the dashboard to open the trunk.

If you need to jump-start a Ford with a dead battery, use the terminals in the engine bay. Do not jump from the battery in the trunk. These instructions may help owners of Ford models such as Fiesta, Mustang, Fusion, Edge, F150, etc.
