Cost to Rekey a Lock in 2026: NYC Locksmith Pricing Guide

Rekeying a lock typically costs $20 to $60 per cylinder for the work, plus a $50 to $125 service call in NYC. A standard 2 to 4 door NYC apartment runs $80 to $250 total. A whole house with 5 to 8 cylinders runs $150 to $400. Rekeying is faster, cheaper, and more secure than buying new locks in almost every situation, with a handful of specific exceptions covered below. Here’s the honest 2026 walkthrough of pricing, what the work actually involves, and when to rekey versus replace.

What Rekeying a Lock Actually Means

Rekeying changes the internal pin configuration of an existing lock cylinder so that an old key no longer works and a new one does. The lock body, the strike plate, the deadbolt, and the door hardware all stay. Only the small brass pins inside the cylinder get swapped out.

Practical effect: the key from the old tenant, the contractor, the ex-roommate, the property manager, all become useless. The new key the locksmith hands you is the only key that works.

Replacing a lock, by contrast, means tearing out the entire cylinder and lock body and installing a new one. Different cost (3 to 5 times higher), different time (15 to 30 minutes longer per door), and different security tradeoffs.

What Rekeying Actually Costs in NYC in 2026

Pricing is built from three things: the service call, the per-cylinder labor, and any extra hardware.

NYC locksmith service call

Cost: $50 to $125

The flat fee for the locksmith to come to your address. Manhattan and Brooklyn typically run higher ($75 to $125), Queens, Bronx, and Staten Island lower ($50 to $90). After-hours, weekends, and emergencies add 25 to 50 percent.

Per-cylinder rekey labor

Cost: $20 to $60 per cylinder

The actual work of pinning the cylinder. A standard 5-pin Schlage or Kwikset takes 10 to 15 minutes per cylinder. A 6-pin or 7-pin commercial cylinder takes 15 to 25 minutes. High-security brands (Medeco, Mul-T-Lock, Abloy) cost more because the pins are more expensive and the equipment is more specialized ($75 to $150 per cylinder).

Total cost by NYC home type

Real 2026 NYC pricing:

Manhattan and Brooklyn pricing tends to be 15 to 25 percent higher than the outer boroughs. After-hours service adds 25 to 50 percent.

What the Locksmith Actually Does on the Call

The work is straightforward but not as simple as it looks online.

1. Removes the cylinder from the lock body (5 minutes per door)
2. Disassembles the cylinder and removes the existing pins
3. Replaces the bottom pins with new pins matched to the new key cuts
4. Replaces or rotates the springs and reassembles the cylinder
5. Tests the new key in the cylinder before reinstalling
6. Reinstalls the cylinder and tests the lock through 5 to 10 cycles
7. Cuts the customer’s working keys to match (typically 2 to 3 keys included)

Total time on a 3-cylinder NYC apartment: 30 to 60 minutes including paperwork.

When Rekeying Makes Sense

Almost every situation where you want to invalidate old keys without changing the lock hardware. The most common reasons:

• Just moved into a new apartment, condo, or house

• Lost a key and don’t know where it is

• Ex-roommate, ex-tenant, or ex-spouse moved out

• Contractor, cleaner, or service provider had a copy

• Suspected unauthorized key duplication

• After a break-in attempt where keys may have been compromised

• Standardizing multiple locks to a single key (key alike)

• Annual security refresh on a high-value property

When Replacement Makes More Sense Than Rekeying

Rekeying isn’t always the right call. Replace the lock when:

• The lock is older than 15 to 20 years and showing wear (springs weak, cylinder wobbly)

• The lock is rated below ANSI Grade 2 and the door is your primary entry (NYC street-level apartments need Grade 1 or Grade 2)

• You’re upgrading from a basic deadbolt to a smart lock or high-security cylinder

• The current lock is damaged from a prior attempted break-in

• You want to switch from a Kwikset to a Schlage, Medeco, or Mul-T-Lock for better security

• You’re consolidating to a smart-home setup (Apple Home Key, Z-Wave for Ring, etc.)

If you’re switching to a smart lock, see our 2026 NYC smart locks guide for the residential and rental-friendly picks.

Rekeying vs. Replacing: The Cost Comparison

For a typical 3-cylinder NYC apartment:

Rekeying is 60 to 80 percent cheaper than even basic replacement. Unless you have a specific reason to upgrade hardware, rekeying is the default for new tenants and post-move-in security.

When You Can’t Rekey (and Have to Replace)

A few specific situations where rekeying isn’t an option:

• The lock cylinder is damaged or worn beyond repair

• The lock is a discontinued model and replacement pins are unavailable

• The cylinder is a sealed or tamper-resistant high-security model where rekeying requires a manufacturer key code (Medeco, Mul-T-Lock require authorization)

• The lock is a basic builder-grade lock with cheap pins that won’t hold a new key cut reliably

• You want to convert from a key-only lock to a smart lock or keypad lock

Builder-grade Kwikset and Defiant locks (the brand most NYC apartment buildings install) can be rekeyed but the pins wear within 2 to 3 years even on light use. If your apartment came with builder-grade locks and you’re planning to stay 5+ years, replacing with mid-grade Schlage or higher is often a better long-term investment.

Frequently Asked Questions

How much does it cost to rekey a house in NYC in 2026?

$150 to $400 for a typical 5 to 7 cylinder NYC house or brownstone, including the service call. Manhattan and Brooklyn pricing trends 15 to 25 percent higher than outer boroughs. After-hours and emergency rekeying adds 25 to 50 percent to the base rate.

Can I rekey a lock myself?

On Kwikset SmartKey locks, yes, the manufacturer sells a rekey kit ($10 to $20) and the process is genuinely DIY-able. On every other brand, no, the rekeying requires removing the cylinder, disassembling it, and matching new pins to a key. The tools cost more than a single locksmith visit and the learning curve isn’t worth it for most homeowners.

How long does NYC apartment rekeying take?

30 to 60 minutes for a typical 2 to 3 cylinder apartment. The locksmith arrives mobile, does the work in your hallway or just inside the door, and hands you 2 to 3 working keys before leaving.

How many keys come with a rekey?

Most NYC locksmiths include 2 to 3 keys in the rekey price. Additional copies cost $3 to $7 each. If you need more (4 or more) for a household, ask up front so they bring the right blanks.

Is rekeying as secure as replacing the lock?

Yes, when done correctly. The pin configuration is what determines key compatibility, and rekeying changes the pin configuration completely. A rekeyed Schlage Grade 2 deadbolt is exactly as secure as a brand-new Schlage Grade 2 deadbolt, just at one-quarter to one-third the cost.

Will rekeying break my landlord’s master key?

In most NYC rental buildings, yes. If your apartment is on a master key system (the building staff can access with a master), rekeying typically removes you from the master. Always check your lease before rekeying a rental. Many leases require landlord approval and require that the new pins be compatible with the building master.

How often should I rekey my locks?

Every time someone moves out (roommate, tenant, family member), every time a service provider had a key for an extended period, after any break-in attempt, and as a baseline preventive every 3 to 5 years for high-value properties. NYC pre-war buildings with shared key histories often benefit from rekeying every 2 to 3 years.

Can a locksmith rekey a smart lock?

Yes, on smart locks that have a physical key backup, the cylinder can be rekeyed independently of the smart functionality. Schlage Encode, Yale Assure, and Kwikset Halo all allow this. The smart codes are managed separately through the app.

What’s the cheapest way to secure a new NYC apartment?

Rekey before you move in (or within the first week). For under $250, you guarantee that no prior tenant, contractor, broker, or property manager has a working key to your space. Replacing locks costs 3 to 5 times more for the same security outcome.

Can all locks be rekeyed?

Most can, but not all. High-security models (Medeco, Mul-T-Lock, Abloy, Bilock) require a manufacturer key code and authorization. Damaged or discontinued cylinders sometimes can’t be rekeyed because the right pins aren’t available. A reputable NYC locksmith will tell you up front if your specific lock can be rekeyed.

Will rekeying void any warranty on my lock?

No. Rekeying is a standard maintenance procedure recognized by all major lock manufacturers. The warranty covers manufacturing defects, not pin configuration changes.
