Moving into a new apartment or house in Brooklyn? A lock change is the first thing you should do. You never know how many copies of the old keys exist. Our locksmiths remove your existing locks and install brand-new deadbolts, knob locks, and entry locksets on the same visit. We carry Schlage B60N, Kwikset 980, and Medeco Maxum deadbolts on every truck — the same locks recommended by NYC housing authorities. Average lock change cost: $75–$150 per lock including hardware.
If your locks are in good condition, rekeying is faster and cheaper than a full lock change. We modify your existing lock cylinders so old keys no longer work, and cut new keys on-site. Ideal for landlords between tenants, roommate changes, or anytime you need fresh key control. We rekey deadbolts, knob locks, and mailbox locks. Average rekeying cost: $20–$40 per lock. Most apartments completed in under 30 minutes.
Locked out of your apartment or house? Our 24/7 emergency lockout team arrives at your Brooklyn location in 15–25 minutes. We use non-destructive entry techniques to get you back inside without damaging your locks or door. Whether it’s a brownstone in Brooklyn Heights, a walk-up in Williamsburg, or a condo in DUMBO — we handle it all. Lockout service cost: $75–$125. No overtime charges for nights, weekends, or holidays.
Upgrade to keyless entry with a smart lock installation. We install and program top-rated smart locks including August Wi-Fi Smart Lock, Yale Assure Lock 2, Schlage Encode Plus, and Kwikset Halo. Smart locks let you unlock your door with your phone, create temporary access codes for guests and dog walkers, and monitor who enters your home. We handle the full installation including Wi-Fi setup and app configuration. Smart lock installation cost: $150–$350 including the lock.
Protect your home against break-ins, lock bumping, and picking with high-security residential locks. We install Medeco Maxum, Mul-T-Lock Hercular, and ASSA Abloy residential cylinders that provide maximum resistance against forced entry. These locks feature patented key control — keys cannot be duplicated at hardware stores without your authorization card. Recommended for ground-floor apartments, brownstones, and homes with high-value contents. Cost: $150–$350 per lock.
Is your lock sticking, turning hard, or not latching properly? Our locksmiths diagnose and repair all residential lock issues on-site. We fix misaligned strike plates, worn cylinders, broken springs, and frozen mechanisms. In most cases, a repair is $50–$90 and saves you the cost of full replacement. We also offer annual lock maintenance service for landlords and property managers.
Lost your mailbox key or is the lock broken? We replace USPS-approved mailbox locks on individual mailboxes and cluster box units (CBUs) in apartment buildings throughout Brooklyn. We carry standard C9100, C9200, and Florence mailbox locks. Mailbox lock replacement: $35–$65 per lock. We also cut duplicate mailbox keys on-site.
Our Brooklyn Heights headquarters at 170 Hicks St, Brooklyn, NY 11201 and our Williamsburg location at 232 Leonard St, Brooklyn, NY 11211 allow us to respond quickly across Brooklyn Heights, DUMBO, Downtown Brooklyn, Williamsburg, Greenpoint, Park Slope, Cobble Hill, Carroll Gardens, Fort Greene, Prospect Heights, and all surrounding neighborhoods.

We recommend at minimum rekeying all locks when you move into any new apartment or home in NYC. You don’t know how many copies of the old keys exist — previous tenants, their friends, building staff, or old roommates could all have copies. If your locks are older than 10 years or show signs of wear, a full lock change to new Schlage or Kwikset deadbolts provides better security. NYC tenant law requires landlords to provide new locks, but many only rekey — upgrading is worth the investment.
Yes. We install August, Yale, Schlage, and Kwikset smart locks on standard apartment doors. Most smart locks fit existing deadbolt holes with no drilling required. We handle the full installation including mounting, Wi-Fi/Bluetooth pairing, app setup, and programming access codes. If you rent, we recommend smart locks that fit over your existing deadbolt (like the August Wi-Fi Smart Lock) so you can take it with you when you move.
Yes. We provide volume rekeying services for landlords and property management companies across Brooklyn. Between-tenant rekeying, master key system setup, and bulk lock installations are our specialty.
