I keep my doors locked for safety reasons, but I do not mind if parents come into my daycare area (I have a separate daycare space in the basement). In fact, I set up an intercom system with my garage door where I let them in without actually going to the door...so they actually have to come in and get their child. To be honest, I have been on the parent's side and it was a very uncomfortable feeling not ever seeing the area where my child played each day (she would bring him dressed to the door). I felt like it was my duty as a parent to see the space from time to time and make sure everything seemed okay (clean, kids happy, etc). Knowing what it's like to be the parent, I put my system in place partly because it is safer for me not to be leaving kids alone to take others to the door, but also because I feel it brings peace of mind to the parents. Now, I would certainly not welcome them to wander around the family areas of my home, but they are welcome to come into my daycare space daily. It is really scary being a parent and leaving your child with a stranger. Now, on the other issues you mentioned...I would ask, why are you allowing her to come earlier and pick-up later? Is that what you agreed to in your original contract? If it isn't working for you, you have to tell the parents and either change it or terminate care. Resenting the parent for something you have agreed to will not get you anywhere.
