Best advise open another account and start again,
Sometimes it's a nightmare's with keys and the key fobs some guest are just plain idiots,
I had to start charging a deposit also we live on an island and it's not easy to get keys cut, almost 15km to the nearest place plus my time.
I only have one apartment on Airbnb at the moment and it has a keycard entry system you would not believe how many guest forget them, go out,
I had a guest not long ago lose one so he says, we had to have all the cards and the lock reprogrammed, We dont have to buy a new lock,
