I live with my parents and am the primary caregiver. I have POA for them. Siblings have recently, without even asking my parents, gotten house keys. They did only have one key, but now they also have made a key for the deadbolt. This is the lock we use when we are at home. When there is someone at home to unlock the door I don't understand why they would need to get in? My mother is not happy that they would also be able to come in and 'snoop around.' She has already caught DIL looking through financial papers. I am worried that they will come in before we have gotten up and scare me - thinking that a burglar has gotten in. My mother wants to change the lock but also worried that they will just stop coming to help with anything. We are getting the feeling that they will help when they can control everything. Already had some boundary problems. Caught in the middle - help!
