Luggage compartment opening

Hello, short simple question: How do I get the trunk open if neither the electrics nor the emergency opening works more? With me, the belt of a carrying bag has been so elegantly tangled that both don’t work anymore. Was in a workshop and mine something of a day’s work. They would have to remove the rear seat and then try to get in the trunk from behind. I’m afraid that doesn’t work. Anyway, I know from the Audi that the trunk and the rear seat with a The car shows in the display that the boot flap is still open. Probably that’s why the opening motor doesn’t start (no matter what I try). And if I try to open it manually, I can’t turn the key to the right. Probably because the lock is not hooked in at all. So, and now I’d like good advice.
