Defiant Deadbolt: What $20 Gets You (and What It Doesn't)

Defiant is a house brand. It has no factory, no engineering department and no independent existence outside Home Depot's shelves — it is a name applied to hardware built by somebody else.

That somebody is Taiwan Fu Hsing Industrial Co. Ltd, one of the world's larger lock manufacturers, which working locksmiths report has produced Defiant hardware exclusively for Home Depot for close to twenty-five years. Community Worth being precise about where that comes from: the figure traces to a Defiant promotional video, reported by a practising locksmith. It is not a filing or a press release, and we've tagged it accordingly rather than promoting it to fact.

This is the same arrangement you'll find behind a great deal of the hardware aisle, and it is not automatically bad. Taiwan Fu Hsing builds to whatever specification the buyer orders. Home Depot ordered a lock to hit a shelf price. That's what arrived.

The criticism that does survive is narrower and more useful: there is no locksmith support network, no parts channel, and no serial-number service path. If a Defiant cylinder fails in eight years, the answer is a new lock from Home Depot under the lifetime warranty — which is a perfectly reasonable answer at this price, and a completely different relationship from the one you get with a manufacturer that stocks replacement parts.

Working locksmiths who have stripped these report a consistent picture: the cylinder on both the Defiant deadbolts and the doorknobs contains five pin stacks, three of them security spools, on the KW1 keyway. Community

Three spools in a twenty-dollar lock is a real result. A spool pin has a waisted middle section, so under tension it catches at the shear line and produces a false set — the plug rotates a few degrees and stops dead. An inexperienced picker reads that as progress and keeps pushing. What they actually have to do is back off the tension and start again. Three of those in a five-pin stack meaningfully slows a beginner down.

It does not slow down anyone with experience, and it does nothing at all about the rest of the lock. Which is the whole review in one sentence: Defiant spent its money in the one place a customer can't see and skipped the places they can.

The drill plate

There is a hardened plate behind the cylinder face, and the marketing counts it as drill resistance. Locksmiths who have gone at one report that it is straightforward to remove. Community Better than a bare cylinder, but closer to a gesture than a barrier, and we're scoring it that way.

The bolt, and a correction

An earlier version of this page listed the bolt simply as "standard", implying it was short. It isn't. Corrected Defiant states that every one of its deadbolts uses a hardened steel bolt with a full one-inch throw — the same projection as the Schlage B60N. Manufacturer The housing is die-cast zinc alloy rather than stamped sheet. Manufacturer

The differences that remain are real but narrower than we implied: bolt diameter, the absence of a hardened free-spinning anti-saw insert, and the strike plate. On throw length specifically, these two locks are equal.

Defiant uses the KW1 keyway — the Kwikset profile, and the most common residential keyway in North America. Community

A Defiant key will physically enter a Kwikset cylinder and vice versa. It won't turn unless the bitting matches, but the blank fits, which means a locksmith can rekey a Defiant to your existing Kwikset keys in minutes without touching anything else on the door.

For a renter, or anyone who has just bought a house already keyed on Kwikset, that is the practical case for this lock: swap the deadbolt, have it cut to your existing key, and you have changed your locks for the price of the hardware plus a rekeying fee. It isn't the secure answer. It is the cheap answer, and sometimes that's the one being asked for.

The flip side is that KW1 means no key control whatsoever. Blanks are on the rack at every hardware store, every kiosk and most supermarkets. Anyone who has held your key for thirty seconds can have a copy, and nothing about this lock will ever tell you it happened. That's equally true of the Kwikset locks it's compatible with — see our SmartKey 980 review, where the key-control problem is even worse — but it's worth saying plainly rather than filing under "compatibility".

An earlier version of this page said Grade 1 gives you "roughly double the tested security and durability" of Grade 3. That was a guess, and it undersold the case badly. Corrected The real figures are on our own grades explainer:

Defiant's own materials describe its Grade 3 certification as surviving 200,000 cycles and two door strikes. Manufacturer That matches the standard, and it is the number to hold onto.

Grade 1 is not twice Grade 3. On impact it is five times. The ram is a weighted pendulum standing in for a shoulder or a boot. Grade 1 hardware must take ten hits and still function. This lock is certified to take two.

Against the Schlage

Two housekeeping notes on that table. Earlier versions of this page quoted the Schlage at "$35–$40" in one place and "$35–$85" in another; the figure recorded in our own B60N review is roughly $33–$52, and that's what we're using. Corrected We also credited Schlage with a "Snap & Stay" installation system; we could not verify that as a Schlage product name and it has been removed. Corrected

Neither lock has key control. Both have a one-inch bolt. Both carry a lifetime mechanical warranty. The gap is everything around the cylinder — the certification, the strike plate, and the anti-saw insert — and it costs somewhere between ten and thirty dollars depending on the day.

There is a real case for the Defiant, and it isn't a grudging one:

• Landlords doing turnovers in volume. Low-risk units, keyed-alike combo packs, replaced rather than serviced. The economics are the point.
• Renters who can't justify $40. Swap it, rekey it to your existing keys, take the old one with you.
• Anyone already on the Kwikset platform who wants one more door on the same key without buying another brand.
• Interior doors, garage side doors, sheds and outbuildings — the places where a lock's job is to mark a boundary rather than resist an attack.
• Right now, because the Schlage peg is empty. A working deadbolt today beats a better one on Thursday.

If none of those describe you, the extra money is the easiest security spend available and you should just make it.

The Defiant isn't a scam and it isn't junk. Five pins with three spools is more cylinder than the price demands, the bolt throws a full inch, the housing is proper cast zinc, and the KW1 keyway makes it the cheapest way to put one more door on a key you already carry. Somebody made real decisions here, and some of them were good ones.

But the good decisions are all inside the plug, and almost nothing that stops a break-in happens inside the plug. Grade 3 means two blows from the ram where Grade 1 means ten. The strike plate anchors to trim. The drill plate comes off. Every part of this lock that a person would actually attack is the part that was built to the price.

So buy it deliberately or don't buy it. For a rental turnover, a shed, an interior door, or a combo pack that puts four openings on one key for under forty dollars, it is exactly the right tool and there's no shame in it. For the front door, walk ten feet and pick up the B60N.

And whichever you buy — spend the eight dollars on a strike reinforcer and three-inch screws. That is the single best-value purchase in this entire category, and it works just as well on the cheap lock as the expensive one.
