Best Door Locks for Home Security in 2026

Before you compare features, look for the ANSI/BHMA grade on the box. It's a simple 1-2-3 rating, and Grade 1 is the strongest. Most residential deadbolts are Grade 2, which is fine for a typical home. Avoid Grade 3 for an exterior door. It's built for interior or light-duty use and won't take much of a kick.

A solid pick for most homeowners is a Grade 1 or strong Grade 2 deadbolt with a one-inch throw bolt and a hardened steel insert that resists sawing. Schlage's B60 series and Kwikset's higher-end deadbolts both qualify. The grade tells you how the lock holds up to force, drilling, and thousands of cycles. The brand name on the front doesn't.

One thing the grade doesn't measure: pick resistance. That's a separate conversation, and it matters more than people think.

Skip the gimmicks and focus on four things. First, a single-cylinder deadbolt (key outside, thumbturn inside) is right for most doors. Only use a double-cylinder (key on both sides) if there's glass within arm's reach of the lock, and even then, check your local fire code first, because keyed-both-sides locks can trap people in an emergency.

Second, look at pick and bump resistance. Cheap pin-tumbler locks open fast in skilled hands. Kwikset's SmartKey and Schlage's higher security cylinders add resistance, and if you want serious key control, brands like Medeco and Mul-T-Lock use patented keyways so nobody copies your key at a kiosk. Third, the strike plate and screws. A lock is only as strong as what holds it to the frame. Fourth, a one-inch deadbolt throw, not the half-inch latch that comes on many doors.

For most North Dallas homes, a Grade 1 deadbolt with a bump-resistant cylinder and a reinforced strike plate covers the realistic threats.

Smart locks have gotten good. A keypad means no spare under the mat, you can give the dog walker a code that expires, and you get a phone alert if the door's left unlocked. For families and short-term rentals around Frisco and McKinney, that convenience is real.

That said, a smart lock is still a deadbolt with electronics bolted on. The mechanical guts decide how secure it is, so buy one with a real ANSI grade, not just a slick app. Keep a mechanical key backup or a keypad you trust, because batteries die at the worst time, usually a cold January morning. Pick a model with auto-lock, low-battery warnings, and a brand that still pushes firmware updates.

Good options pair a Grade 1 or 2 build with a keypad or smart module from established makers. If you're going keyless, plan for the day the power or the battery quits, not the day it works.

Here's the part the box won't tell you: most break-ins don't pick the lock. They kick the door, and the wood splits around the strike plate. You can spend $300 on a deadbolt and still lose if it's screwed into a flimsy frame with short screws.

Do these four things and you'll stop more attacks than any lock upgrade alone. One, swap the strike plate screws for three-inch screws that bite into the wall stud, not just the door jamb. Two, add a reinforced strike plate, often called a box strike or a security strike. Three, check that the deadbolt fully extends into the frame without sticking, because a half-thrown bolt is half a lock. Four, make sure the door slab itself is solid-core, not hollow.

These fixes cost little. Most of them are a screwdriver and a trip to the hardware store. If a door is sagging, the bolt won't line up, and that's worth a pro's eye.

New house in Allen or Prosper? You don't always need new locks. If the existing deadbolts are decent Grade 1 or 2 hardware, rekeying is faster and cheaper than replacing. Rekeying changes the pins inside the cylinder so the old keys stop working, which is exactly what you want after a move, a breakup, or losing track of who has a copy.

Replace the lock instead of rekeying when the hardware is corroded, sticky, a flimsy Grade 3, or so old you can't get parts. Also replace if you're upgrading to a smart lock or want a patented keyway like Medeco for key control. A locksmith can usually tell in a minute by feeling how the cylinder turns and reading the grade stamp.

A realistic rekey runs in the low double digits per lock plus a service call, while a full deadbolt swap with quality hardware often lands in the $150-250 range per door installed. Numbers vary with the lock you choose.

You don't need a fortress. For most homes in the McKinney area, here's a sane setup. Put a Grade 1 deadbolt with a bump-resistant cylinder on every exterior door. Reinforce each strike plate with a box strike and three-inch screws. Add a smart keypad lock on the door you use daily if the convenience is worth it to you, and keep a mechanical backup.

If you want keys that can't be copied at a hardware store, step up to a patented keyway like Medeco or Mul-T-Lock on your main entries. Then do the boring stuff: trim shrubs near windows, light the entry, and don't leave the garage-to-house door unlocked, because it's the softest entry point in most houses.

If any of this feels like guesswork, that's normal. Choosing the right grade, matching it to your door, and installing it so it actually holds is where a licensed locksmith earns the call.
