I can't tell you how many times I go out to rekey one or let someone in, and I find problems. If it's not installed right, it won't protect you. Here's what you need to know before hiring a handyman.

An experienced house locksmith knows dead bolts should have at least a one-inch “throw.” On the “strike side,” there should be a security plate with screws at least three inches long that go all the way into the door’s wood frame. Look out for these signs your house is vulnerable to burglars.

Most are mass-produced by reputable manufacturers but to very low standards. Look for at least a grade 2. Here are more things you should never buy at big-box stores.

Don't fall for these sneaky ways con artists try to win your trust. They’ll quote you a great price, but when they get there, they’ll say you have a special lock they can’t pick, so they have to drill it open.
