Retrieving the mechanical key
Jaguar uses four versions of Smart Keys fobs. For the first one, press and hold the release button while pulling the key blade from the Smart Key (remote control or ‘clicker’) body. The release button must be pressed as well to return the key blade.
For the second, press and hold the release button on the side of the fob, while lifting 
the emergency (mechanical) key blade cover from the Smart Key body. Extract the emergency key blade and unfold. On some models, the lock cylinder (keyhole) at the back of the door handle will be visible. If so, use the key blade to unlock the door.
The third version hides the mechanical or emergency key beneath a chrome cover on one side of the fob. Slide the side cover towards the top of the fob as shown to release and remove it. The mechanical key can then be slipped out the same way and unfolded.
Note that we have seen fobs of this type from Land Rover that were missing their fold out keys! If you run into this, you will, unfortunately, need to get in touch with your dealer as soon as possible.
The newest version of the fob is thankfully a simple side button press (arrow, right) and a pull. The mechanical key is the key ring end of the fob. We have seen two instances of mechanical keys missing from key fobs in the previous styles. This will not be an issue with the newest fob.
Most of the vehicles using the versions 3 and 4 key fob all have hidden key holes, so move to the next steps, below.
Getting Inside
E-Pace, F-Pace, XE, XF and XJ
For some Jaguar models built after 2015 and using the last two key fob styles, there is a cap at the back of the driver’s door handle that must be removed to get to the key hole. There is an access hole or slot beneath the cap. Insert the key blade into the slot and, except with the XJ, press down on the cover slightly. Gently lever the key blade upwards and rotate the lock cover upwards to release it. And yes, you are prying off a piece of the car but its ok and necessary.
Once you have exposed the lock cylinder, use the mechanical key to unlock the driver’s door. The alarm sounds until the Smart Key is positioned correctly. To disarm the alarm continue to Starting Instructions in Part II.
I-Pace and F-Type
These models have flush door handles that reach out when the driver touches it while an active key fob is present. They will remain fixed if the key fob’s battery is dead or there is interference.
The lock cylinder is hidden behind the flush handle. To get at it, press the front of the 
handle (right). The rear of the handle will be pushed out. Pull the entire handle out to the fully deployed position.
Once you have exposed the lock cylinder at the rear of the handle, use the mechanical key to unlock the driver’s door. Again, the alarm sounds until the Smart Key is positioned correctly. To disarm the alarm continue to Starting Instructions in Part II.
