Are Your Locks Actually Good Enough? A 5-Minute Security Check

Are Your Locks Actually Good Enough? A 5-Minute Check

Why Most Locks Fail (And How to Spot Yours)

Your front door lock looks fine. It turns. It clicks. But that doesn't mean it's secure.

Most residential locks installed by builders are ANSI/BHMA Grade 3, the minimum acceptable standard. They'll stop an opportunist trying the knob, but not much else. A determined intruder with a screwdriver can pop many Grade 3 deadbolts in under a minute if the strike plate is flimsy or the screws are short.

The good news: you can assess your locks right now without special tools. Walk to your front door and check five things. Takes five minutes.

Check 1: What Grade Is Your Deadbolt?

Turn your deadbolt and look at the faceplate (the metal edge in the door frame). You might see a stamp: Grade 1, Grade 2, or nothing at all. No stamp usually means Grade 3.

Grade 1: Highest residential rating. Resists 10 strikes at 75 pounds of force, 250,000+ cycles. These cost more but they're worth it for exterior doors.

Grade 2: Mid-tier. Five strikes at 75 pounds, 150,000+ cycles. Acceptable for most homes, significantly better than Grade 3.

Grade 3: Builder-grade. Two strikes at 75 pounds, 50,000 cycles. If your deadbolt has no visible rating, assume this. It's the legal minimum, not a security standard.

If you have Grade 3 locks on exterior doors, upgrading to Grade 1 is one of the simplest security improvements you can make. A professional can rekey and upgrade in one visit.

Check 2: How Long Is Your Deadbolt Throw?

Lock your deadbolt. Open the door and measure how far the bolt extends from the edge of the door into the frame.

Anything under 1 inch is weak. The bolt needs to sink deep into the strike plate and frame. A half-inch throw can be pried or kicked loose. A full 1-inch throw (or longer) makes forced entry much harder.

Most modern deadbolts offer at least 1 inch, but older locks, especially those installed in the 1980s or earlier, often fall short. If yours is short, replace it. You can't fix throw length; it's built into the lock.

Check 3: Is Your Strike Plate Reinforced?

The strike plate is the metal bracket screwed into the door frame where the deadbolt lands. Most builder-installed plates are thin stamped metal held by two half-inch screws that barely bite into the frame.

Open your door and look at the strike plate. Is it a flimsy L-bracket with short screws? Or a heavy-duty box strike with screws at least 3 inches long that anchor into the wall stud?

A proper strike plate should be solid steel, at least 1/8-inch thick, with a recessed box that wraps around the bolt. The screws should be 3+ inches and penetrate the framing lumber behind the trim. This is where most kick-in attacks succeed, the lock holds, but the frame splits. Upgrading your strike plate costs less than $50 in hardware and makes a bigger difference than most lock upgrades.

Check 4: Can You See Daylight Around Your Door?

Close your exterior doors. Stand inside and look at the edges, top, and bottom. Do you see light seeping through gaps?

Visible gaps mean the door doesn't sit flush in the frame. That's a problem. Even a Grade 1 deadbolt won't help if someone can slip a pry bar into a quarter-inch gap and lever the door open. Gaps also let in drafts, which drives up energy bills, but the security risk is worse.

If you see light, you need weatherstripping at minimum. If the gap is wide or the door sags, you might need the frame adjusted or the hinges reinforced. A mobile locksmith can assess both the lock and the door-frame fit in one visit, check our services page for details.

Check 5: Are Your Windows and Sliding Doors Locked?

Front-door security gets attention, but intruders often bypass it entirely. Ground-floor windows and sliding glass doors are easier targets if they're not secured.

Walk around your home. Check every accessible window. Do the locks actually engage, or are they painted shut, broken, or missing? Sliding doors should have a secondary lock or a wooden dowel in the track. The factory latch alone won't stop someone lifting the door off its track from outside.

If you find broken window locks or weak sliding-door hardware, fix them. This isn't paranoia, FBI data consistently shows forced entry through windows and secondary doors is nearly as common as front-door attacks. For comprehensive security advice, visit our blog for more guides.

When to Rekey, Upgrade, or Replace

If your locks passed all five checks, you're in good shape. If not, here's what to do:

Rekey if: Your locks are Grade 1 or 2, but you've moved in recently, lost a key, or ended a relationship where someone else had a key. Rekeying changes the pins so old keys won't work. It's faster and cheaper than replacing the whole lock, and a mobile locksmith can do it on-site in minutes.

Upgrade if: You have Grade 3 locks, short deadbolt throw, or weak strike plates. Swapping to Grade 1 deadbolts with reinforced strikes is a one-time cost that pays off in security and insurance discounts in some cases.

Replace if: Locks are visibly damaged, sticky, or so old the manufacturer no longer makes parts. Trying to repair a lock that's failing internally usually costs more than replacing it outright.

Not sure which applies? A locksmith can assess everything in one visit and quote you a flat rate before starting work. No surprises.

Frequently Asked Questions

What's the difference between Grade 1, 2, and 3 locks?

ANSI/BHMA grades measure durability and forced-entry resistance. Grade 1 is highest (commercial-quality, used in homes for maximum security), Grade 2 is mid-tier residential, and Grade 3 is minimum builder-grade. Higher grades use thicker materials and withstand more force.

Can I rekey my locks myself?

Technically yes if you buy a rekey kit, but it requires removing the lock, disassembling the cylinder, and matching new pins to a new key without mistakes. Most people find a locksmith faster and cheaper when you factor in the risk of breaking the lock or ordering wrong parts.

How much does it cost to upgrade to Grade 1 deadbolts?

Expect $100, $250 per door for the lock, installation, and a reinforced strike plate. Prices vary by lock brand and whether you're also rekeying. A mobile locksmith can give you an exact flat-rate quote over the phone before dispatch.

Do smart locks make my home more secure?

Smart locks add convenience (keyless entry, remote access) but aren't inherently more secure than a high-grade mechanical deadbolt. Security depends on the lock's physical build, check the ANSI grade, deadbolt throw, and strike-plate quality just like any other lock.

What if my door frame is damaged or rotted?

A better lock won't help if the wood around it is soft. You'll need the frame repaired or reinforced first, often with a steel security plate or a full jamb replacement. A locksmith can identify frame issues during a security assessment and recommend next steps.
