Who has a key to your home?

For major renovations or new construction, contractors often install locks with master pins that work with multiple sets of keys. Learn more about master pins and tips to hire a trustworthy locksmith.



I just moved into a new home, and had a locksmith change my locks. He found exactly what this video talked about - there was a master pin in both of my deadbolts, so that the builder could still come in my home. What this video said is true, and I'm so glad I got my locks changed!

Sound very uneven, spoiling a good video

Master keys work for someone who needs access to a lot of properties without the hassle of carrying a whole ring of keys e.g in my rentals, but no one, even the maintenance people get one. If a homeowner is gone the Gen'l contractor can remove the lock and get it rekeyed to match your key and you would not know it was changed. I've also used a separate lock during a construction phase and then replaced it when the new tenant moves in. or a lock box with a 4 digit code I give to the subs. that code can change as well. if anything suspicious is going on. Also in most home with security systems there is a separate code which contractors can use to disarm the system. But it is best to change it entirely
