My car is locking me out.

2010 Jaguar XFR Supercharged

 

My car is locking me out.

It will not read my key, while it in my hand. When I push the button to unlock the door it will not unlock or lock, none of the buttons work when it's doing this. Eventually, I am able to get the door unlocked. Then when I get in to start the car, it says "no smart key found." When I unhook the car battery and plug it back up I am able to open the door and start the car.

 

Does anyone know why what this could be?

I have gone to different shops, and they say, it's my key. But if I buy another key and it continues to keep happening, I would have spent over seven hundred dollars for a key for nothing.

I have noticed that the 2 times it happened to me it had been raining. I don't know if that has any significance. 

Ps. NEW BATTERY IN THE FOB and in car.

Does the spare key work as it should?

Does the car “see” the non-working fob when you dock it in slot to the lower left of the steering wheel?

I don't have a key cut for it yet. When I try to put it in the dock it tells me that the smart key is not found.  So I have been using my key fob.

These are the codes that Midas found.

So right now, in order to start the car, you have to disconnect then reconnect the main battery?

[Battle817]

Yes, just when the key won't work.

Have you repositioned the fob battery as the contacts within the fob are quite fragile and can easily lose touch with the battery in the fob?

Do you have a second fob, i.e. 2 x keys? Have you tried to use the second key?

Unfortunately I do not have a 2nd key. The 1st time I got locked out I was looking to get a 2nd key fob and a key cut. I could try that.
