What lock replacement in Dallas covers for Arlington properties.
Arlington sits between Dallas and Fort Worth, and the housing stock reflects that - a large share of the city's single-family homes were built between the 1960s and the 1990s, which means a lot of existing hardware is builder-grade and long past its designed lifespan. Neighborhoods like Pantego borders, South Arlington near the Entertainment District, and older subdivisions off Collins Street frequently turn up with deadbolts that have worn cylinders, loose strike plates, or misaligned bolts that never threw correctly to begin with.

Lock replacement means removing the existing hardware completely - cylinder, bolt mechanism, strike plate - and fitting a new unit that matches the door prep. It is different from rekeying, which keeps the existing lock body and only changes the pin stack inside the cylinder. When the lock body itself is broken, corroded, or too worn to rekey reliably, replacement is the right call.
We carry Grade 1 and Grade 2 deadbolts, standard knob and lever sets, keyed entry handlesets, and common smart lock models on the truck. Most Arlington residential replacements are done in under an hour per door.
Call 469-300-5525How a door lock is built, and why worn parts can't be adjusted away.
Understanding the hardware makes the replacement decision straightforward.
Cylinder, bolt, strike plate
A deadbolt has three working parts. Each one can fail independently, and a failure in any one of them means the lock is not doing its job.
The cylinder is the part you put the key into. Inside it, a stack of spring-loaded pins aligns when the correct key is inserted, allowing the plug to turn. When the pins are worn, the key starts to stick or the cylinder turns stiffly. When the cylinder is damaged from a forced entry attempt, it may turn without moving the bolt at all.
- CylinderHouses the pin stack. Worn pins cause stiff operation. A damaged cylinder after a break-in attempt often looks intact from outside but won't move the bolt.
- Bolt mechanismThrows the bolt into the strike plate when the cylinder turns. Worn internal springs can leave the bolt partly retracted even when the key turns fully.
- Strike plateThe metal plate in the door frame that receives the bolt. A standard builder-grade strike plate is held by short screws that don't reach the stud - upgrading to a 3-inch screw strike plate is part of most replacements.
- BacksetThe distance from the door edge to the center of the lock hole. Standard is 2-3/8 or 2-3/4 inches. The replacement lock has to match the existing prep or the door needs drilling.
Four situations that call for replacement, not rekeying.
Rekeying is cheaper. But these four situations need a new lock.
Check this first
Does the key turn smoothly and the bolt throw fully?
If the key sticks, the bolt won't throw all the way, or the cylinder spins without engaging, the lock body itself is the problem.
Before deciding between rekeying and replacement, it helps to know which situation you are dealing with.
The lock was forced or tampered with
A deadbolt that has been attacked - kicked, drilled, or picked repeatedly - often has internal damage that isn't visible from outside. The cylinder may still accept a key but the bolt mechanism is compromised. Rekeying a damaged cylinder does not restore structural integrity. Arlington Police recommend replacing hardware after any break-in, not just rekeying it.
The hardware is builder-grade and more than 15 years old
Most production homes built in Arlington in the 1970s through 1990s came with Grade 3 or unrated hardware. These locks are not designed for long-term security use. The pin stacks wear out, the bolt mechanisms weaken, and they are straightforward to pick or bump. Replacement with a Grade 1 or Grade 2 deadbolt is the practical fix.
The cylinder is stuck and the key won't come out
A cylinder that traps the key or won't release it past a certain point usually has a broken wafer, a failed anti-pick pin, or a spring that has collapsed inside. Once the cylinder is stuck in that state, it needs to come out. A replacement cylinder or a full new lock goes in its place.
You want a smart lock where a keyed lock was
Most smart locks replace the entire interior assembly and sometimes the exterior cylinder too. The door prep usually works, but the backset, bore size, and door thickness have to be confirmed before we order or bring hardware. Tell us the door details when you call and we will confirm compatibility.
Not sure whether you need replacement or a rekey? Call and describe what the lock is doing. We will tell you which applies before anyone drives out.
Call 469-300-5525How lock replacement in Arlington actually works.
We start by confirming the door prep so the replacement hardware fits without modifying the door.
Remove the old hardware. The deadbolt, knob set, or lever comes out - cylinder, bolt mechanism, trim, and all mounting screws. We inspect the door edge and frame for damage before the new lock goes in.
Upgrade the strike plate. Standard builder strike plates use short screws that only reach the door jamb, not the stud behind it. We replace them with a heavy-gauge plate and 3-inch screws that anchor into the framing.
Install and align the new lock. The new deadbolt or knob set goes in, the bolt is checked for full throw into the strike plate, and the cylinder is tested with the key several times. Fit, not just function, matters - a bolt that throws stiffly against the strike plate will wear the cylinder faster.
Rekey to your existing key if you want it. If you are replacing one lock among several and want them all on one key, we can rekey the new cylinder to match the others on the same visit. This avoids carrying multiple keys.
What it costs depends on the grade of hardware, the number of doors, and whether you are adding smart lock capability. See the Dallas locksmith cost guide for how pricing works.

Tell us the door details on the call
When you call 469-300-5525, tell us your location in Arlington, what the lock is doing, and the door material if you know it. For smart locks, door thickness and existing backset matter. We confirm what hardware we will bring before dispatching.
- Step 2
Technician removes and inspects
The old lock comes out and the door edge, bore, and frame are checked before anything new goes in. If there is frame damage or a bore that needs modification, we tell you on the spot with a clear cost before proceeding.

The new hardware goes in, the bolt throw is checked against the strike plate, and the key is tested multiple times in both directions. Any rekeying to match other locks in the house is done last, and we confirm the key works before we leave.

Lock replacement questions we hear most from Arlington customers.
How do I know if I need replacement or just a rekey?
If the lock body works correctly - the key turns cleanly and the bolt throws fully - but you just want to change who has a working key, a rekey is the right call and costs less. If the cylinder is stuck, the bolt won't throw all the way, the lock was forced, or the hardware is old builder-grade, replacement is what fixes it. Call and describe what the lock is doing and we will tell you which applies before dispatching.
How much does lock replacement cost in Arlington?
Cost depends on the grade of hardware, the number of doors, whether you want smart lock capability, and the time of day. Grade 1 deadbolt replacements cost more than Grade 2, and smart lock installation adds time for pairing and setup. We quote before anyone drives out. The Dallas locksmith cost guide on this site explains how pricing is structured.
Can you replace my lock and rekey it to match my other locks?
Yes. We carry rekeying tools on the truck and can pin a new cylinder to match your existing house key on the same visit. Tell us on the call that you want them matched so we confirm the cylinder we bring is rekeyable to your key profile.
Do you carry hardware on the truck or do I have to buy it first?
We carry common Grade 1 and Grade 2 deadbolts, standard knob and lever sets, and several smart lock models. For less common hardware - specific finishes, high-security cylinders, or commercial-grade locks - call ahead and we confirm availability before dispatching.
How long does a lock replacement take in Arlington?
A single deadbolt replacement on a standard wood door with an existing bore typically takes 30 to 45 minutes. Adding a knob set or lever on the same door adds another 20 to 30 minutes. Smart lock installation takes longer if the door needs a new bore or if the hub and app pairing requires troubleshooting. Multiple doors in one visit are more efficient than separate calls.
What grade of deadbolt should I put on an Arlington home?
ANSI Grade 1 is the highest residential rating and holds up better to physical attack than Grade 2 or Grade 3. Older Arlington neighborhoods with 1970s and 1980s construction often have Grade 3 or unrated builder hardware still on the doors. Grade 1 is the practical upgrade for any exterior door used regularly. We stock both and can show you the difference in bolt thickness and cylinder quality on site.
