ignition hole cover/clip
 

Hi - Its my first time on here and im hoping someone can help! After a recent valet the small circular clip/cover that covers the emergency ignition port on a keyless start model has come off and vanished - I cannot for the life of me locate this part anywhere in the uk, Can anyone assist please as its driving me bonkers!
Im not sure how to add a photo but im led to believe the part number is:-
BBM3-67-H41
Thanks in advance
