When a lock needs to go — not just be rekeyed

Some locks have earned retirement: the deadbolt that needs a hip-check to throw, the knob that spins a little too freely, the builder-grade cylinder that was never great to begin with. We replace worn, damaged, and outdated locks with hardware that actually resists force — installed square, tested, and backed by Texas Locksmith License B19775. You approve the quote before anything comes off the door.

What a proper lock change includes

Hardware matched to your door. Backset, bore size, door thickness, handing — we measure before we recommend, so the new lock fits the existing prep instead of fighting it.

Honest grades. Lock grades aren’t marketing — Grade 1 hardware survives more force and far more cycles than the bargain bin. But not every door needs it, and we’ll say so when a solid Grade 2 deadbolt does the job for less.

The frame check most installers skip. A strong deadbolt in a weak frame is false security — most forced entries break the jamb, not the lock. We check the strike plate and frame, and reinforce with 3-inch screws into the stud where it’s warranted.

Old hardware off, new hardware proven. We test the latch, the throw, and the key before we call it done.

Two honest detours: if your hardware is fine and you only need old keys to stop working, rekeying is cheaper and we’ll tell you. And for whole-home projects — several doors, maybe a smart lock in the mix — start at the residential locksmith page. Businesses, see commercial locksmith for storefront and office hardware.

After a break-in attempt
Replace the damaged lock — but look at the frame and strike plate too, because that’s usually what actually gave way. We assess both and quote the repair honestly, without turning one bad night into a whole-house upsell.

Should I buy locks myself, or do you supply them?
Either works. We carry quality residential hardware on the van and can quote options in your price range — or install locks you’ve already bought, as long as they fit your door prep (we verify before drilling anything).
What’s the difference between Grade 1 and Grade 2 locks?
ANSI grades measure durability and force resistance. Grade 1 is the strongest rating — commercial-level — while Grade 2 is solid residential hardware. We recommend by door and risk, not by price tag.
Will a new lock fit the holes in my existing door?
Usually yes — most residential doors share standard prep. We measure backset and bore before installing, so you’re not left with a misaligned latch or visible gaps.
Someone tried to break in. What should I replace?
Start with the damaged lock, but have the frame and strike plate checked too — forced entries usually break the jamb first. Reinforcing the strike with long screws is cheap and adds real resistance.
