First service airbag msg then a few days later My key wouldn't come out so I left it there overnight to fins out it was inn acc position next morning & battery dead. Googled & got key out using hole under ignition & screwdriver. Charged got bad battery msg on charger. Replaced battery car starts but still got airbag msg & still have key issue. Tried to hook up obd2 but port is dead???? Any reasons come 2 mind?? For both key issue & obd issue or r they connected to airbag msg maybe too?
