My realtor gave key to buyer under contract

Under contract with a buyer. My Realtor represents both of us. I am selling it with owner financing, my realtor has all ready given a key to the buyer we don’t even have a set close date yet. I was originally selling it furnished but this buyer doesn’t event want the furnishing I had moved most the stuff out but they have now removed the rest of the furniture from the property. My father in-law went up today to get some lazy boy recliners and said the place is completely empty... then when I asked my realtor who had the key she lied and said she did. When I had just texted the buyer and they said they had it. This realtor is also the broker the property was a vacation property in a small town population is only 645 and she is the only real-estate agent up there.
