My friend you aren't thinking. The ONLY way to remove the lock without damaging the door is to do it with a screwdriver from the inside. Secondly, my wife is 75 years old and has arthritis problems. She also had rotator cuff surgery this past February. If she went out the emergency exit and fell to the ground the injuries she would sustain might very well be life threatening. You conduct that drill at your leisure if you like. I will remove the lockset from the inside and save my wife from all the injuries.
