Thank you to everyone who commented about my lock and key issue yesterday. In the comments Teddy Rose said "do not pass go, do not stop to collect $200, do not blog, get the locks changed now, as in yesterday!"
I'm telling you, I could do with that $200 right about now. Today I took the day off at work, and the locksmith came and changed every lock in the house that could be changed, as well as adding one to the garage door. So, several hour and $600 later, we are feeling a little more secure.
I may have to replace two screen doors and maybe look at some kind of security system, but for now, anyone using the old keys won't be able to get into the house at all, and that is the main thing.
