How much does it cost to change locks on two doors? Here’s the structure up front: the total is built from hardware, labor, and a one-time service fee for the visit. The hardware tier you choose moves the number more than anything else — basic locksets cost far less than smart or high-security models — and doing both doors in one appointment is cheaper than two separate visits because you pay the trip fee once. Need it after hours? An emergency surcharge applies on top. Below is the full breakdown — how hardware tier, timing, and door condition move the number, and when rekeying can cut the bill in half.
Two-door lock change costs at a glance
| Item | What drives the price |
|---|---|
| Typical total, two doors (parts + labor) | Hardware tier per lock, one shared visit |
| Per-lock replacement range | Knob locks lowest; smart and high-security top |
| Average cost per lock | Mid-grade deadbolts set the midpoint |
| Locksmith labor, hourly | Drilling or door prep adds time |
| Minimum service / trip fee | Paid once per visit |
| After-hours surcharge | Nights, weekends, holidays cost more |
| Emergency visit total | Immediate dispatch, late-night travel |
| Rekeying instead (per lock) | Keeps existing hardware — the budget option |
A professional can change a standard residential lock in about 20 to 30 minutes, so both doors are usually done within the hour. If the goal is simply making old keys stop working — after a move, a lost key, or a roommate change — read our guide on how much it costs to rekey a lock first; rekeying keeps your existing hardware and costs a fraction of a full change.
What the hardware costs, by lock type
The lock you choose is the single biggest factor in your final bill. For two doors, you can mix and match — many of our customers put a high-security deadbolt on the front door and a standard lock on the second door.
- Basic lockset / locking doorknob: the budget tier. Fine for interior doors and privacy, but not recommended as the only lock on an entry door — the mechanism is less resistant to force.
- Standard deadbolt: the mid-grade workhorse. A deadbolt’s solid bolt can’t be forced back the way a spring latch can, which is why it’s the baseline we recommend for any residential door that faces the outside world.
- Smart lock: a step up in price. Keypad, phone, or fingerprint entry, guest codes, and usage notifications — a genuine convenience upgrade if you’re tired of keys.
- High-security lock: the premium tier. Drill- and pick-resistant construction with complex pin systems and hardened steel. Worth it for street-facing doors and anyone who wants the best defense available.
What else moves the price up or down
- Door condition. If the new lock doesn’t match the old bore holes, or the frame is warped or damaged, the locksmith may need to drill or adjust — extra labor that adds to the bill. Badly damaged doors may need door repair before a new lock will seat correctly.
- Timing. Weekday business hours are cheapest. Nights, weekends, and holidays add an after-hours premium, and a full emergency locksmith visit bills at the top of the scale.
- Location. NYC labor rates run higher than suburban averages — the quote reflects real travel and parking time across Manhattan, Brooklyn, and Queens.
- Extras. Additional key copies, smart-lock programming, and reinforced strike plates each add modest line items. Ask for them in the same visit — it’s cheaper than a second appointment.
Rekey, repair, or replace?
Before paying for two new locks, check whether you actually need them. Rekeying — changing the internal pins so old keys stop working — costs a fraction of what a full replacement with labor can reach. If your current locks are in good condition and the problem is who has keys, rekeying both doors is the smart move; our rekey vs. replace guide walks the decision through. Repair makes sense for a sticky lock or misaligned latch — but if the fix costs 50% or more of a new lock’s price, replace it. Replace when hardware is old, damaged, or you’re upgrading security; details and hardware options are on our lock change service page.
DIY vs. hiring a pro
Swapping a basic doorknob yourself costs only the price of the hardware, versus a professional install of the same lock with parts and labor included. For one simple interior lock, DIY is reasonable. For entry doors, smart locks, or high-security hardware, an improperly installed lock can be easy to bypass, damage the door, or void the manufacturer’s warranty — and when a locksmith supplies the lock, the guarantee typically covers both the product and the work. Two entry doors is exactly the kind of job where the pro’s precision pays for itself.
Getting a fair two-door quote
Ask for an itemized estimate up front: hardware for each door, labor, trip fee, and any after-hours charge. Confirm the locksmith is licensed and insured, ask about their arrival window, and ask whether they discount the second lock — most do, since the travel is already covered.

Frequently asked questions
How much does it cost to change locks on two doors, bottom line?
Plan on a total built from two locks’ worth of hardware plus one visit’s labor and service fee. Two basic deadbolts land near the low end of the scale; two smart or high-security locks push higher. Call (212) 204-1655 with your door details for a firm two-door quote.
Is it cheaper to do both doors in one visit?
Yes. The minimum service fee is paid once, and most locksmiths discount additional locks in the same appointment. Two separate visits would nearly double the fixed costs.
Is rekeying just as secure as replacing the locks?
Yes — as long as the existing hardware is in good condition. Rekeying makes every old key useless while the lock’s physical strength stays the same. Replace only if the hardware is worn, damaged, or due for a security upgrade.
How long does the job take?
About 20 to 30 minutes per standard lock, so both doors are typically finished in under an hour. Smart locks or doors needing modification take longer.
What do locksmiths charge per hour?
Most NYC locksmiths bill by the hour, and quotes across the industry vary with job complexity and hardware. On top of labor there’s the one-time minimum trip fee, which is why bundling both doors into one appointment is the biggest single saving.
Why does emergency service cost more?
The after-hours surcharge covers a technician on call around the clock — immediate dispatch and late-night travel. An emergency visit bills at the top of the scale, and it’s what you’re paying for when a lock change genuinely can’t wait until morning.
Ready to book both doors in one visit? The single-appointment saving only shows up when the tech arrives with the right hardware for each door, so tell us what’s on them when you call. Schedule a professional lock change for both doors or call (212) 204-1655.
