lets say you have a 4 story building with 10 offices on each floor.
total 40 locks each needs a key that opens only that lock. then you
have cleaning people that clean only one floor so now you need a key
that will open every lock on each floor but no locks on any other
floor.then the the building manager needs a key that will open every
lock in the building. so you have 40 separate keys 4 master keys and
one grand master key.does home depot sell this setup for 29.95 per
lock? if they do then i agree with you we dont need locksmiths anymore,
becase the only other thing they can do is open the safe you inherited
from your family member who passed away and you can do that with the
small torch set that home depot sells.those papers that burnt werent
important anyway were they?
