Rekeying and replacing are both the right answer, just not for the same situation
Rekeying costs less and solves most situations homeowners face.
Rekeying means changing the internal pin configuration inside your existing lock cylinder so old keys no longer work. Replacing means removing the lock entirely and installing new hardware. The honest answer depends on three things: why you're calling, what condition your locks are in, and what security grade your current hardware actually is. Here's how to know which one your Dallas home needs.
Dallas homes carry a wide range of lock conditions, and that changes everything
The lock hardware on a Dallas home tells a specific story depending on where and when it was built.
An older Oak Cliff bungalow might have original knob locks from the 1970s: functional-ish and a Grade 3 at best. A new construction home in Prosper or Celina almost certainly has builder grade cylinders. They work fine, but they're the minimum the builder was required to install.
Here's what most homeowners don't realize about builder grade locks: the cylinder quality is often good enough to justify rekeying. The hardware body is brand new. Replacing it would be money spent on something that didn't need replacing.
On the flip side, a worn lock in an older East Dallas property might have a cylinder that's been rekeyed two or three times already. The tumblers are loose. The keyway is wallowed out. That lock deserves replacement, not because rekeying won't work mechanically, but because the housing itself has earned retirement.
Lock condition, not just key control, is the real starting point for this decision.
Three times rekeying was the right call, and one time it wasn't
Most Dallas homeowners who call us after moving into a new house don't need new locks.
Here's a scenario we handle constantly. A family closed on a house in Richardson, newer construction, solid Kwikset deadbolts on both the front and back doors. The previous owner had three copies of the key out there: the real estate agent, the seller's adult kid, and a neighbor who used to water plants.
That's a classic key loss scenario, where one or more copies of a house key are unaccounted for. The family called us expecting to spend several hundred dollars on new hardware.
We checked the deadbolts first. Both were Grade 2, solid, not worn, and less than four years old. The lock body was sound. The keyway was clean. There was no reason to replace them.
We rekeyed both cylinders, cut two new keys on site, and that family had full key control in under 45 minutes. The old keys won't turn those cylinders anymore. The locks themselves are the same locks, just set to a new pin stack (the driver and key pins inside the cylinder that determine which key profile operates the lock).
Now here's the scenario where the answer flipped. Same neighborhood, older house from the mid 1990s. Single knob lock on the front door, no deadbolt. The homeowner called after a breakup rekey situation: a former partner still had a key. We could have rekeyed it. We didn't recommend it.
A knob lock with no deadbolt on a primary entry door is a security downgrade risk. It puts the homeowner in a position of paying to re-pin hardware that wasn't protecting them adequately in the first place. We recommended replacing the knob lock and adding a Grade 1 deadbolt above it. That's the honest call.

Sound hardware, full key control restored in under 45 minutes. No reason to replace a lock that isn't the problem.
If it doesn't need replacing
We say so. If it genuinely does, we explain why before we touch anything.
Our standards for knowing which service is right
Our process starts with a lock condition assessment before any recommendation is made.
A lock condition assessment is a visual and functional inspection of your existing hardware. We check for wear on the cylinder, the condition of the bolt mechanism, the security grade of the lock body, and whether the door frame itself is reinforced enough to matter.
If your hardware is in good shape and your reason for calling is key control (moving into a new place, losing a key, a relationship change) rekeying is almost always the right answer. If the hardware is worn, damaged, a low security grade, or missing a deadbolt entirely, we'll tell you that directly, before any work starts.

Checklist
What we check on every job before we quote a service
- Cylinder inspectionWe check for wear, looseness, and whether the keyway has already been rekeyed multiple times.
- Hardware grade checkWe identify the ANSI lock grade (Grade 1, 2 or 3) of your existing hardware. Grade 3 locks are often worth replacing rather than rekeying.
- Door frame reviewA rekeyed lock on a weak door frame doesn't add real security. We flag this.
- Reason based matchingKey loss and relationship changes point toward rekeying. Damage and low grade hardware point toward replacement.
- Transparent recommendationWe tell you what we found and why we're recommending what we're recommending.
Assessment first. Recommendation second.
What shapes whether you need to rekey or replace
Six real scenarios. Six clear verdicts. No "it depends" as a final answer.
When rekeying is the right move3
- Scenario 1You just moved into a Dallas home, and the hardware is solid.
Previous owners and agents had keys. The deadbolts are Grade 1 or Grade 2, less than ten years old, and in good working condition. Verdict: rekey. You get full key control without replacing hardware that doesn't need replacing.
Rekey - Scenario 2You lost a key and your locks are newer.
A key is somewhere out there. Your Schlage deadbolt is two years old and the cylinder is tight. Verdict: rekey. The lock is fine, the pin stack just needs to be reset.
Rekey - Scenario 3A breakup or divorce rekey situation.
A former partner has a key. Your hardware is in good shape with no damage or forced entry. Verdict: rekey. It's faster and resolves the key loss scenario completely.
Rekey
When replacement is the right move3
- Scenario 4Your door only has a knob lock with no deadbolt.
Rekeying a knob lock that's your only line of defense isn't a real security upgrade. Verdict: replace the knob lock and add a deadbolt above it.
Replace - Scenario 5Your locks are visibly worn or have been rekeyed multiple times.
A loose cylinder, worn keyway, or significant age isn't worth re-pinning. You'd be paying to reset a lock that's already failing. Verdict: replace.
Replace - Scenario 6You're upgrading from builder grade to something better.
New construction in Frisco or McKinney works fine, but it's the builder's minimum. Rekeying won't change the grade of the lock body. Verdict: replace with the grade you actually want, then key it to your preference.
