safe lock blocks passenger door

hello community has the following problem…my safe guard (that’s what the adac man called and explained (if you use the remote control to close the door 2 times)) can no longer be unlocked on the passenger side. so you can neither open the door by remote control nor by hand. I have also only closed the door on the driver’s side and the passenger door does not react! you don’t notice any twitching or similar in the pen with which you can open the door. n. the door paneling can unfortunately not be removed without damage because the screws are on the b-pillar or at the entrance bar and you can’t get there… my problem is that I’m going to work with the car and 2 colleagues abroad this evening and therefore have quite bad contact with a FOH or my workshop 🙁 …the adac mann said however that there would probably be crash sensors that would unlock this safe security just at a crash! now my question: k can you trigger these sensors somehow from the engine room? does anyone know the problem? the FAQ didn’t help me any more… many thanks already in advance and beautiful Sunday!
