I purchased a wrecked 2018 M3 with a blown pyrofuse. No airbags were deployed but I think the driver's seatbelt srs module went off. The 12v battery is entirely dead. I contacted the previous owner who said he had a few Tesla key cards but wasn't sure which was for the old Tesla. He was nice enough to give me both his key cards to test on the old car to see which is the correct key card. After hooking up a jumper battery to the car and seeing the car's screen monitor boot up I tried both key cards on the pillar key sensor- neither card would lock/unlock the car.
Question: After an accident/blown pyrofuse does the functionality of the key card stop working until the fuse is replaced?
