I work away from home for most of the week. My neighbourhood is what they describe as 'gentrifying' but we still get a lot of break-ins. It's mostly just kids who take advantage of unlocked doors and windows so I have upgraded the locks to ones that are harder to break into. I don't have a lot of valuable stuff, but it's not a great feeling to come home to a house that has been ransacked. This blog has tips on the most secure door and windows locks on the market that can be used for upgrading the locks on your home.
