How Much to Rekey a House in Charlotte: Real Costs vs Replacement

Rekey vs replace: the decision tree

Rekey when the hardware is in good shape and you just want to invalidate every old key. Replace when the hardware is failing, you want to upgrade the security grade, or after a break-in damaged the cylinder. For 90 percent of Charlotte rekey calls, the right answer is rekey, because most homes have hardware that is functioning fine and the homeowner just wants to know that previous keys do not work anymore.

The math is direct. A rekey of 5 cylinders in a standard Charlotte home runs about $200 inclusive. Replacing 5 cylinders with comparable Schlage or Kwikset hardware plus the labor to install them runs $500 minimum, up to $1,500 if you upgrade to mid-grade hardware. Replacement makes sense when the hardware needs swapping anyway, not as a substitute for rekeying.

Charlotte rekey pricing table

Cylinder type	Per-cylinder rekey	Notes
Standard Schlage or Kwikset	$20 to $30	Most Charlotte residential hardware
Standard Defiant or generic builder-grade	$20 to $30	Common in new construction in Ballantyne plus Steele Creek
High-security Medeco or Mul-T-Lock	$40 to $60	Restricted keyways, more complex pinning
Schlage Primus (high-security)	$35 to $55	Pin-and-side-bit pinning, more time per cylinder
Older 1920s mortise (Plaza Midwood plus Dilworth and NoDa bungalows)	$40 to $80	Different cylinder, sometimes needs new pinning

Service call adds $50 to $75 to cover the trip. After-hours adds another $50 to $100. The full breakdown lives on the cost page.

Why move-in day is the right rekey day

Charlotte's housing market sees high turnover, especially in the inner ring plus the Ballantyne corridor. The previous owner of your house probably gave keys out to multiple people during their tenure. The cleaning service got one. The dog walker got one. The neighbor with the spare-key arrangement got one. Maybe a contractor mid-project still has one in a tool bag. None of those people have any current reason to enter your house, but they all have physical access.

Rekeying the day you take possession solves this in one visit. You move in knowing no other key in existence opens any of your doors. The cost (around $200 for a typical Charlotte home) compares favorably to the cost of dealing with a stranger using an old key six months later. We schedule a lot of these on closing day or the day after, because move-in day is when the homeowner already has movers and HVAC techs onsite anyway.

How rekeying actually works

The mechanical work is straightforward. We remove the cylinder from the lock, pop the cylinder cover, and dump the old pins. We measure the cut depths on a new key (which we cut from a fresh blank in the truck) using a pinning kit, then drop in fresh pins matched to the new bitting. The cylinder gets reassembled and reinstalled in the door. The old key no longer turns the cylinder because the pin heights no longer match the cuts on the old key.

The whole sequence takes about 5 to 10 minutes per cylinder on a standard residential lock. Older mortise cylinders take longer because the cylinder design is different. High-security cylinders take longer because the pinning kits use more piece parts (sidebar pins, finger pins, master wafers). At the end of the visit you walk out with two or three new keys, and any old keys you hand us get cut up so they cannot be reused.

What about smart locks?

If you have a smart lock like a Schlage Encode or a Yale Assure, you do not need a rekey because the smart lock uses electronic credentials (numeric codes, fobs, plus phone keys), not physical keys. You change the codes from the app. Most smart locks also have a backup key cylinder, and that backup cylinder can be rekeyed using the same process as a standard residential cylinder. If the previous owner had a backup key, get the backup cylinder rekeyed even if you change all the electronic codes.

Hybrid setups (some doors smart, other doors keyed) are common in Charlotte. The smart locks get a code change. The keyed cylinders get rekeyed. Total job runs roughly the same as a full keyed-cylinder rekey because the labor is in the keyed cylinders, not the smart-lock side.

Common Charlotte rekey scenarios

1. Move-in day after closing on a house anywhere in Mecklenburg County.
2. Lost key with no clear sense of where it ended up. Maybe at the gym, maybe in a parking lot, maybe in a kid's backpack.
3. Roommate move-out where the keys were never returned cleanly.
4. Contractor finish where the contractor had a master key during the build.
5. Post-break-in when the burglar may have copied a key found inside.

How to prepare for the rekey appointment

Bring nothing special. We bring the pinning kits, the blanks, plus a cutter built into the truck. Have working keys for every cylinder you want rekeyed (so the tech can verify each cylinder opens correctly before and after the work). If a cylinder is already malfunctioning, tell us on the dispatch call so we can bring replacement hardware in case the rekey is not the right answer for that specific door.

Plan for 45 to 90 minutes at home for the appointment. The tech will walk through the house with you, identify every cylinder, confirm the rekey scope, then work through them one door at a time. At the end you sign off and pay, then walk away with the new keys plus a written summary of what was rekeyed.
