What It Costs to Rekey Locks, and What Changes the Price

The cost to rekey a lock is built from three separate pieces: a call-out that covers getting a technician to your door, a labour charge per cylinder, and a small parts cost for the new pins and cut keys. The important consequence of that structure is that the first lock on a visit always costs the most, and every additional cylinder afterwards costs considerably less, because the call-out has already been paid.

That is why rekeying five doors is nowhere near five times the price of rekeying one, and why doing the whole house in a single visit is the best value available in this kind of work.

What actually drives the number

• How many cylinders, which is the biggest factor by far. Count deadbolts and knobs separately, because a door with both has two cylinders.
• The type of hardware. A standard residential deadbolt is quick. A mortise lock in an older Charlotte home, a commercial lever, or a high-security cylinder takes longer and needs different pinning.
• Whether everything is keyed alike, which is usually included and occasionally adds a little where cylinders come from different manufacturers.
• How many keys you want cut, since the first two or three are typically part of the job and extras are cheap to add at the same time.
• When you call. Standard hours cost less than an evening, a weekend or an urgent same-day visit.
• The condition of the lock, because a seized or badly worn cylinder may need work before it can be rekeyed at all.

The mixed-manufacturer problem

Worth understanding before you get a quote, because it surprises people. Rekeying works within a manufacturer’s keyway. A cylinder from one maker and a cylinder from another accept physically different key blanks, so they cannot be keyed to the same key without changing hardware.

Plenty of Charlotte homes have picked up mismatched hardware over the years: the original builder deadbolt on the front, something different on the back after a break-in or a repair, and a third thing on the door from the garage. If you want one key for everything, one or two cylinders may need swapping to match the rest. That is a hardware cost on top of the rekey, and it is almost always still cheaper than replacing every lock in the house.

Rekeying versus buying new locks

Rekeying is the cheaper option whenever the hardware is sound, and it produces the same security outcome for the thing most people are actually worried about, which is who still holds a working key. New hardware makes sense when a cylinder is worn out, when it is low grade and sitting on a door that matters, or when you want something the old lock cannot do such as a keypad.

The mistake worth avoiding is replacing perfectly good hardware because a hardware store shelf made it feel like the obvious move. Rekeying changes who can open the door, which is usually the entire question.

When you should be rekeying

The clearest trigger is closing on a house. Charlotte’s growth means a very high volume of closings every month, and in the window between listing and handover a key can pass through a seller, their family, a cleaner, a stager, a contractor, an inspector and an agent lockbox. None of that is sinister and no seller can honestly promise every copy came back.

Other triggers: a lost keyring, a tenant moving out, a housemate leaving, the end of a relationship, a contractor who had access during a renovation, or simply not knowing how many copies exist. Rental turnover is the routine case, and rekeying between tenancies is the baseline most property managers work to.

What a quote should include

Ask for a total, itemised, before anyone drives out. That means the call-out stated separately, the per-cylinder rate, how many keys are included, and whether keying alike is part of the price. Ask what happens if a cylinder turns out to be seized or damaged, and what that changes.

Be careful with a headline price that sounds unusually low. A very cheap figure quoted over the phone is a recognised pattern that ends with a much larger number once the technician is on site. A legitimate quote will also come with a business name that matches the vehicle and the invoice, and the technician will ask you to prove you have a right to be in the property. ALOA, the trade’s professional body, treats that verification as a baseline requirement, and it is the same check protecting your home from the next person who calls about it.

The upgrade worth adding while someone is there

Since the labour is already on site, this is the cheapest moment to fix the thing that actually fails during a break-in. Most forced entries split the door jamb rather than defeating the cylinder, which is why reinforcing the door frame matters as much as the lock itself. Swapping the short screws in the strike plate for three-inch screws that reach the framing, and fitting a reinforced box strike, costs very little alongside a rekey and does more for the door than any pinning change.

The same applies to the door from an attached garage, which in a great many Charlotte builds carries an interior-grade knob and no deadbolt at all despite being an exterior door in every practical sense. Layered thinking of this kind is what the National Crime Prevention Council has always recommended over single-product fixes.

Getting the most out of one visit

Before you call, walk the house and count every cylinder including the garage service door, any gate, and the mailbox if it is keyed. Decide whether you want one key for everything. Note any lock that already sticks or needs jiggling, because that is a cylinder nearing the end of its life and it is better dealt with now than during a lockout.

One visit, every cylinder, one key, and the strike plates upgraded while the technician is on the step. That is the version of this job that gives you the most for the money.
