21 Secrets Locksmiths Won’t Tell You

How to outsmart burglars and what they're really thinking when you call at 2 a.m.

A lot of us do undercover work for the cops


We make keys for them and get them into places at 3 a.m. so they can set up surveillance equipment or put the bugs in place. It's part of the thrill of doing what we do.

Contractors stink at installing dead bolts


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 to know before hiring a handyman.

The best lock is a dead bolt that’s properly installed


It should have at least a one-inch “throw,” and 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. These are signs your house is vulnerable to burglars.

Use a double cylinder lock to avoid break-ins


If you have a window on or near your door, a thumb-turn dead bolt won’t do much good. They knock out the glass, stick a hand in, and turn. Get a double cylinder lock that needs a key on the inside.

Think twice before you buy a locked safe at a flea market, estate sale, or auction

It's probably going to cost you $300 or more to open it, and chances are, all you're going to find is mouse poop.

When you buy a new house, always have your locks rekeyed


Otherwise there's probably a master key out there that can easily open your home.

Keys stamped “Do not duplicate” are duplicated all the time


Ask me about high-security locks with keys that can’t be replicated at the hardware store.

You're supposed to check ID before you open anything


But half the time when someone is locked out of their house or car, where do you think their ID is?

These are the biggest mistakes people make with their safe:


Spinning the dial too fast, trying to open it before it's unlocked, and forcing it closed when there's obviously a problem.

It’s easy to defeat the cheapo locks from big-box stores


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

I've seen my share of dead bodies


It's always a bad sign when the landlord calls to get into an apartment, and nobody's seen the tenant for ten days.

Divorce lock-outs are a challenge


The soon-to-be-ex wife will call and say she’s locked out, so I get her in and change the locks. Then the husband calls with the same request. I refer him to a competitor.

Don't feel bad if you have to call me twice in a short span of time


I once had a guy lock himself out of his house three times in one day.

If you’re locked out, please call just one of us


More than once, I arrived at a lock-out to find two competitors’ trucks already there. At that point, we all agreed to leave and abandon the inconsiderate victim.

Never tell me, "Don't worry. It's an easy lock."

Every time someone says that, it takes an extra 10 minutes to get it open. It's the kiss of death.

If you call at 2 a.m., bewaware


If some guy calls me because he’s locked out of his car at a strip club, a service call that’s normally $55 is automatically $100. If he’s got money for strip clubs, he’s got money for me.

Don’t believe a car dealer who says only he can duplicate keys

In most cases, a locksmith who specializes in automotive work can make you a key—usually cheaper.

Try the door


I’ve gone to houses and found it open. (I’m still going to charge you for the service call.)

If your key won’t turn, try WD-40 or silicone spray


Sometimes the pins get jammed up, and 25 to 40 percent of the time, that solves the problem. Here are more brilliant uses for WD-40.

Have a housekeeper who needs a key?

Ask me to key your door so that your master key works on both the dead bolt and the doorknob, but hers works just on the knob. On the day she comes, lock only the knob.

Many locksmiths in the phone book or online are scam artists


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. Then they charge you $125 for a replacement lock you can buy at Home Depot for $25. Find someone reputable at findalocksmith.com, the official website of the Associated Locksmiths of America.
