how to lock fuel-lid?

Guys

I dont have this problem with my volvo S40. the fuel-lid cover can only be opened with a touch button in the dashboard. However, this bmw doesn't have that same lock-in feature. Everytime i sent my car for washing, the guys accidentally flip open the fuel-lid during the cleaning/wiping process and i have to quickly push it back. this is not good and unsafe. is there a way to mitigate this?

AFAIK from asking the SA you can only lock the fuel lid when u lock your car doors and it opens when u unlock your doors.

Bmw's fuel lid locks and unlocks with the doors.
