Can you please help me with a Car Service?
Thank you .

Press lock and unlock button on the remote. If it does not work out, you can still start the car by placing the remote on the left side of the steering wheel. You can see a rib portion in that area, that's where you placed the remote.

 

Hello, I tried and unfortunately it doesn't start.
It appears on the car dashboard that the less key cannot be found

 

Oh I see, you are in the XF x260 (2015 - current models). There could be a different procedure how on older models. Please copy an paste your original post on XF x250 (2007 - 2015)
