Hello and thanks in advance! I was/am in a two-year lease on a house in Denver, CO. I found a new apartment and submitted a 60-day notice to vacate. A friend picked up a package on the last day of the 60-day period and was seen and photographed by nosy neighbors. The keys were then left in the house as per our agreement. The landlord has called me to tell me she has changed the lock on the front door because the home is "no longer secure" and intends to change the back lock as well. She is now demanding rent for this month despite wanting to claim the keys (she could not find them but I have since left her a message letting her know where they are). She also threatened to get an arrest warrant for my friend for trespassing, despite us the supposed leasees giving them permission. Is it legal for her to charge me this rent or take me to small claims despite her changing the locks without my consent/claiming my keys? It seems to me that she has a clear understanding that we will not be coming back to the property.
Additional info: it's legal for me to record our phone conversations in Colorado, so I have evidence that she has changed the locks and will claim my keys.
