Retrieving the mechanical key
Ford vehicles use a number of different Intelligent Access 
(IA) (remote control or ‘clicker’) key styles. Two of the key fobs use a sliding release on the back side to release the key. Two new key fobs use a push button to release the mechanical key, and one is much easier than the other to use. Another holds the key inside the fob itself and is really difficult to remove.
To release the mechanical key blade in your IA key fob, slide the release on the back of the transmitter and pull the blade out. You can now use the mechanical key to unlock the driver’s door.
An exception is the third key fob style shown. In this case, the removable mechanical key blade is held inside the fob. Slide the release on the back of the remote control (top arrow) and pivot the cover off 
(pull is straight up and off) to access the key blade. Its awkward and may take some practice. That mechanical key can now be used to unlock the driver’s door.
This fourth and unusual Intelligent Access key fob is found with only a handful of Ford models. The mechanical key blade is found on the back of the fob. 
To remove it, push the buttons on either side of the key fob.
We have not seen one of these, so it is not immediately obvious if the mechanical key stays attached to the fob, as it would appear from the image, or if it can actually be removed.
Finally, this last key fob was introduced in some Fords in 2017, and it is the simplest to use. 
It has a push button on the front of the mechanical key itself near the key ring space. Simply push the button and pull the mechanical key away from the IA key.
Getting Inside
Fusion
In 2013, the Ford Fusion became yet another car that has the key hole hidden under a cap at the back of the driver’s door handle. The 2015 Mustang and 
the 2016 Edge and later models have since been added to this list.
To remove the cap, insert the key blade into the slot on the bottom of the handle (right image, bottom arrow) and press up. While holding that upward pressure, move the cap rearward to release it. Gently remove the key while doing so. Yes, the effect is that of prying off a piece of your car but its OK and necessary!
To reinstall the cap, place it just forward of the key cylinder. While applying pressure to the cap, move it forward until it is in place. It snaps into place. Make sure the cap is properly installed by trying to move it rearward.
Remember, getting IN the car is most important. If you have difficulty replacing the cap, don’t bother. Let your dealer do it when you get a new battery for your IA Key Fob!
Look for video help here.
Expedition
The Ford Expedition is updated for 2018, and features another way to hide the key hole. The door handles are a single piece. The key hole is easily exposed by simply pulling the driver’s door handle. It is seen angled outward at the back end of the handle. Insert the mechanical key and turn clockwise. Remove the key and release the handle. The door will open on the next pull. Note that the alarm will sound in a minute or so if the car is not started in time.
GT
GTThe Ford GT uses all electronic locks and latches. The end result is that there is no key hole to unlock a door. So, to get in, you’ll need to open the rear hatch!
Use the mechanical key to open it. A key hole is located just above and to the right of the license plate, as depicted in the image to the right. Note that if you have the rare 
Competition Series GT, the key hole is on the top of the hatch.
Once the hatch is open, look for a release cable and handle located at the upper left of the storage area beneath the hatch, as seen in the image. Pull the handle to release the driver’s door.
Mustang Mach E
The new all electric Mustang Mach E uses electronic latches. A button above the door handle (right) is pressed and the door pops open. If the key fob is dead, the vehicle offers is no opportunity to use the mechanical key to get inside. However, the car can be accessed with an app on your smart phone or using the keyless entry code panel on the door post.
