Retrieving the mechanical key
Lincoln 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 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 need a little 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 to from the image, or if it can actually be removed.
Finally, this last key fob was introduced in most Lincolns 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
Most Lincoln vehicles have a key hole visible at the back of the driver’s door handle. So, simply insert the key and turn, and you’re in!
However, the 2017 Continental and 2020 Aviator bring a very new wrinkle into the mix. The key hole is hidden by a spring-loaded cover and is in a very different location. The key hole has been placed in the chrome molding beneath the driver’s door mirror and behind the imprinted words ‘Continental’ or ‘Aviator’. Simply insert the key and turn to unlock the car. The door will spring open. No word on how well the key hole cover will behave in icy weather.
In addition, the Navigator, updated in 2018, hides the keyhole in plain sight. The door handle is a single piece. The key hole is exposed by simply pulling the driver’s door handle away from the body of the car. 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.
Finally, the new Nautilus model hides the key hole under a cap at the back of the driver’s door handle, which must be removed. To do this, 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 Key Fob!
