Very, Very rarely does a crook pick a lock. 99.9% of the time they just kick in the door or break a window to get in. Either the front or back, depending on neighborhood activity, dogs, bushes, etc. Also, 99% of the time they knock on the front door or ring the doorbell first to see if anyone is home. Thus, it is a good idea to have some sort of video doorbell that notifies you if someone walks to your front door. You can then answer through the speaker and just tell them you are busy in your home office and wont be opening the door for them. They will just go to another home to try.
