tough job.

Seriously, this would mean serious jobs for house-breakers to get in and decipher this lock? Do you think this double-chain lock would be enough security for you in case some attempted break-in would happen? I can get paranoid with locks at time that is why even after checking them before going up to bed, I still ask the husbo to check it again before he sleeps.

How paranoid can you get when you think about your home safety?
