Dallas Rekey vs Replace Residential Locks: Real 2026 Cost Guide and When Each Is the Right Answer

TL;DR for Dallas Homeowners

If you just bought a Dallas home, just had a tenant move out, or just had a roommate leave on bad terms, you have two options for securing the house against the old keys: rekey the existing locks (re-pin the cylinders so the old key no longer works) or replace the locks entirely (new hardware, new keys). Rekeying runs $20-$45 per cylinder plus a typical service-call fee of $55-$95 — a 6-lock house rekey runs $175-$365 all-in. Full replacement runs $85-$285 per door depending on hardware quality — a 6-lock house replacement runs $510-$1,710 all-in. The right answer depends on the existing hardware: if your locks are recent, branded, and in good condition, rekey. If they are 15+ years old, off-brand, or showing wear, replace.

This guide breaks down the actual security difference between the two approaches, when each is the right answer, what real 2026 Dallas pricing looks like for both, and the specific scenarios where one is clearly the better call.

The Security Difference Between Rekey and Replace

Both rekey and replace achieve the same primary outcome: the previous owner's key no longer opens your door. The difference is in what hardware you end up with afterward.

Rekey: The locksmith removes the existing cylinder from each lock, dumps the old pins, and re-pins the cylinder to match a new key. The lock body, deadbolt, latch, and strike plate remain the same — only the pin configuration changes. The new key works; the old key does not.

Replace: The locksmith removes the entire lock assembly (deadbolt body, latch mechanism, strike plate, sometimes the entire door knob set) and installs new hardware. New key, new mechanical components, new security ratings (potentially).

The functional security difference: rekey changes the keying but does not upgrade the lock's mechanical or design security. If your existing locks are low-grade builder hardware (common on Dallas tract-housing builds from the 2000s and 2010s), rekeying preserves the same modest pick resistance, bump resistance, and bypass vulnerability that came with the original install. If your existing locks are ANSI Grade 1 or Grade 2 commercial-rated (Schlage B-series, Kwikset SmartKey, Medeco, etc.), rekeying is functionally equivalent to replacement.

Per the American National Standards Institute (ANSI) Builders Hardware Manufacturers Association published standards, residential locks are graded into ANSI/BHMA Grade 1 (commercial-grade), Grade 2 (heavy residential), and Grade 3 (standard residential). Most Dallas builder-grade hardware is Grade 3 — adequate for normal residential security but vulnerable to specific bypass techniques.

When Rekey Is the Right Answer

Rekey is the right call when:

• You just bought the house and you do not know how many copies of the old key are circulating
• You had a roommate or tenant leave and you want to invalidate their keys
• You lost a key and want to invalidate it without changing hardware
• Your existing locks are recent (under 10 years), branded (Schlage, Kwikset, Baldwin, Medeco), and in good mechanical condition
• You want the cheapest secure option for handling a keying change

A typical 6-door Dallas house rekey: 2 deadbolts on the front door (main + storm), 1 deadbolt on the back door, 1 deadbolt on the garage entry from the house, 1 keyed knob on the front door, 1 keyed knob on the back door. Six cylinders total. Real 2026 cost: $175-$365 depending on whether all six match a single key (called "master keying" or "all keyed alike") or use multiple key combinations.

When Replace Is the Right Answer

Replace is the right call when:

• Your existing locks are 15+ years old and showing wear (sticky cylinders, loose deadbolt action)
• Your existing locks are off-brand or unknown make with no clear security rating
• You want to upgrade to higher-security hardware (Grade 1 vs Grade 3, or pick-resistant cores)
• You want to add smart-lock features (keypad, Bluetooth, Wi-Fi, Z-Wave)
• A lock has been damaged during a break-in attempt or attempted entry
• You are renovating and updating the visual hardware to match new doors

A typical 6-door Dallas house replacement with mid-range Schlage B-series hardware: $510-$910 all-in. Same job with Grade 1 commercial-rated hardware: $850-$1,710. Same job with smart locks (keypad + Wi-Fi on the front and back doors only): $850-$1,450.

Real 2026 Dallas Pricing

| Service | Typical 2026 Dallas Cost | |---|---| | Single cylinder rekey | $20-$45 per cylinder | | Service call / dispatch fee | $55-$95 | | 6-door home rekey (all keyed alike) | $175-$365 | | Single Grade 3 deadbolt replacement | $85-$165 installed | | Single Grade 2 deadbolt replacement | $135-$245 installed | | Single Grade 1 deadbolt replacement | $185-$385 installed | | Single smart lock (keypad) replacement | $185-$285 installed | | Single smart lock (Wi-Fi enabled) | $285-$485 installed | | 6-door home replacement (Grade 3 builder-grade) | $510-$910 | | 6-door home replacement (Grade 2 mid-tier) | $810-$1,310 | | 6-door home replacement (Grade 1 commercial) | $1,110-$1,710 |

Add-on services common on these calls:

• New key cuts (additional copies): $4-$12 per key
• Master key configuration (one master opens all, individual keys for each lock): +$25-$75 setup
• Re-keying to existing key (so a new lock matches your old key): +$15-$35 per cylinder
• Strike plate hardening (replace builder-grade strike with 3" screw security plate): $25-$45 per door

Per the Builders Hardware Manufacturers Association published consumer guidance, the single highest-ROI residential security upgrade is replacing the strike plate with a hardened plate using 3-inch screws into the door framing. This $25-$45 upgrade prevents the most common forced-entry method (kicking the door in) for a fraction of the cost of upgrading the lock itself.

What Experts Say

"Most Dallas homeowners who call about rekeying are weighing it against a much more expensive full replacement they do not actually need. If the existing hardware is a recent Schlage or Kwikset and the action is smooth, rekeying is the right call — same security outcome at a quarter of the price. The exceptions are damaged locks, off-brand hardware, and homes where the owner specifically wants to upgrade. The other thing every homeowner should consider is the strike plate — three-inch screws into the framing is the single best $30 you can spend on home security." — ALOA-certified residential locksmith, 14 years Dallas metro service, anonymized

Per the Associated Locksmiths of America (ALOA) published residential security guidance, the recommended professional workflow on a rekey call is: visual inspection of existing hardware, mechanical test of cylinder and deadbolt action, recommendation based on age and condition, written estimate, and execution. Skipping the visual inspection step is the most common reason a locksmith over-quotes a replacement when a rekey would have served the same purpose.

Real Dallas Residential Scenarios

Scenario A — Just-closed home purchase in Plano: New homeowner wanted all keys invalidated. Six exterior locks, all Schlage F-series from a 2018 build. Locksmith rekeyed all six to a single new key in 90 minutes on site. Total cost: $245.

Scenario B — Post-divorce key invalidation in Highland Park: Owner wanted all locks rekeyed plus an upgrade to higher-security hardware on the front door. Locksmith rekeyed four interior-facing doors ($165) and replaced the two front doors with Grade 1 Medeco hardware ($485). Total cost: $695.

Scenario C — Rental property turnover in Oak Cliff: Landlord wanted rekey on three doors after a tenant move-out. Builder-grade Kwikset hardware from a 2015 build, all in good condition. Locksmith rekeyed all three to a new key in 40 minutes. Total cost: $145.

Scenario D — Break-in attempt damage in East Dallas: Front door had visible pry damage on the deadbolt. Locksmith assessed and recommended full deadbolt replacement plus strike plate hardening. Replaced deadbolt with Grade 2 Schlage B-series ($165), hardened strike plate ($35). Total cost: $225.

Frequently Asked Questions

Q: How long does a Dallas rekey take? A: For a typical 4-6 door home, 60-120 minutes on site. Each cylinder takes 8-15 minutes to dump pins, re-pin, and reassemble. Service call dispatch adds 25-45 minutes of drive time depending on location in the metro.

Q: Can I rekey my own locks instead of calling a locksmith? A: For Kwikset SmartKey locks specifically — yes, with the included reset tool. The DIY rekey on SmartKey takes about 60 seconds per lock. For Schlage, Baldwin, Medeco, and most other brands, you need a pinning kit ($45-$95), follower, plug spinner, and several hours of practice. Most Dallas homeowners find the $30-$45 per cylinder professional rekey cheaper than the DIY learning curve.

Q: Is rekeying really as secure as replacing the locks? A: For the same brand and grade of hardware, yes — the security comes from the lock's design and grade, not from how recently it was rekeyed. Rekeying changes the pin configuration but not the mechanical security characteristics. If your existing hardware is solid, rekeying is equivalent to replacement at a fraction of the cost.

Q: Should I get all my locks keyed alike (one key for everything) or keep separate keys? A: All-keyed-alike is the most common Dallas residential choice — one key opens every exterior lock. The trade-off: if that key is lost or compromised, every lock needs to be rekeyed. For most homeowners, the convenience outweighs the risk. Master-key configurations (one master for all, individual keys for specific locks) are typically only worthwhile for rental properties or large multi-family homes.

What to Do Right Now

If you need to invalidate keys to your Dallas home today:

1. Walk through your home and count the locks that need re-keying (front door deadbolt + knob, back door, garage entry, side door, etc.). Six locks is typical for a 4-bedroom Dallas home.
2. Inspect each lock. If they are Schlage, Kwikset, Baldwin, or Medeco and in good mechanical condition (smooth turn, no sticky cylinders), rekey is likely the right call. If they are off-brand or 15+ years old, replacement is likely the better call.
3. Call a licensed Dallas locksmith for an in-home estimate. Verify the Texas DPS Private Security Bureau license number before authorizing work.
4. Consider adding strike plate hardening on at least the front and back doors — the highest-ROI residential security upgrade available.

A correctly chosen rekey or replacement gives you the same key-invalidation outcome with materially different cost and security characteristics. The right answer depends on what hardware you already own.
