drop off safe doesn't accommodate all VW keys

My car booked for a service this Friday but I had to drop it off early as I work far. there is a drop in safe where you can drop in the keys if you bring car outside business hours. This service is pretty useless to me as the hole of the drop in safe is too small for Toureg keys. When I leave the keys with security guard she says she is not allowed to take them. So what must happen now? must I be late for work because of a malfunction in a drop off safe and there are no mitigating factors for their shortfall? Nxa. ****ed off is an understatement.
