"Smart Key not Found, Refer to Handbook"
My 2014 Jaguar XJ is giving me the message "Smart Key not Found, Refer to Handbook" - The battery had died yesterday so I had to jump it, once jumped it ran fine, but it would not recognize the Key Fob.
Both Key Fobs do not work - Also I tried changing the battery in one, and still no dice.
Does anyone have any idea? or Suggestion? Thanks a million in advanced.

When you say not working, does that mean the lock/unlock don't even toggle your door locks on the vehicle? Make double sure you replace with a new/fresh battery. I put a battery in mine and it turned out to not be fresh and the one Fob did not work, but once I replaced the battery, it was back to functioning.
Sometimes I get the key fob not found when it is in my pocket after I enter the vehicle. Taking out of my pocket and holding near under the steering wheel always picks it up. I believe the sensor is located under the steering wheel.

I am at the dealer changing the main car battery. Hopefully that will fix the issue.

Glad to hear you figured it out. Every so often after i remote start my car, and i get in using keyless, i get the message that the key is not found. Which is obviously inaccurate, because it let me in the car. Sometimes i actually have to physically move the key from my bag in the back seat to the front, and then the car is happy again.
Just one of our "quirks and features" i guess, haha

Hi all< Just a quick message on this topic and hope it might help someone. Ive had my 2014 XJ about 4 years without a problem until last week when my Key fob stopped working with proximity. All of the other functions were fine, I could open doors and lock them pressing the buttons, I could open the boot. The problem was that the car would not sense the key fob when trying to start the car. I had to place the Fob against the dash bellow and right of the steering wheel.
I replaced the battery in the fob and no joy. I used the spare fob with new battery, no joy. I looked at many youtube videos and one over riding point made by people was to disconnect the battery, leave it for a while and reconnect. I did this, with the car unlocked, I removed the red positive and then the black negative. I even pressed the break pedal (Someone explained about draining capacitors - I just did it) I left the car for a little over 10 minutes, started to make dinner, and returned to reconnect the black then the red.
I got in the car, pressed the start button and bingo!!!!! What a relief. Jaguar quoted me £1000 for two new Fobs and the receiver!
One of the other messages I have had for some time is that the battery is low please start the car. That message has also gone. So in a nutshell, disconnect the battery positive and negative. Leave for 10+ mins. Reconnect and see if it fixes it, I hope it does. Good Luck
