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 We replace worn, damaged, and outdated locks with hardware that actually resists force — installed square, tested, and backed by Texas Locksmith License B19775.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.
