Still need assistance with the key issue .
As understood the FOB works but not the key in the door .
This is probably due to the key never being used . spray WD40 in the key hole and wait for it to soak in .
then try inserting the key and wiggle it around ,it will eventually loosen up and turn .
If this does not work then you will need to remove the door panel and check the linkage are all free and move .
if all are free you will have to replace the key cylinder .
Need further assistance with this issue then please get back to me .
Kind regards Greg
