Your front door lock is your home's first and most important line of defense. When that lock is compromised — whether through age, a lost key set, a recent move, or a break-in — K&D Locksmith NYC delivers fast, professional lock change service throughout the Bronx. Our licensed technicians arrive fully equipped with a complete inventory of Grade-1 deadbolts and high-security cylinders, so we can assess your door and install the right hardware without a second trip.
From Mott Haven and Hunts Point to Pelham Gardens and Kingsbridge, we've helped thousands of Bronx homeowners, renters, and business owners upgrade their locks and restore their peace of mind. Every lock change we perform is backed by our commitment to quality workmanship and transparent pricing — no surprise charges, no upsells. We give you a clear quote before we start, install the hardware correctly the first time, and hand you your new keys before we leave the driveway.
Five common situations that call for a lock change — don't wait until it's too late.
Previous tenants or owners may have given out copies to contractors, neighbors, or former occupants — you can't know how many keys are out there.
A compromised lock must be replaced immediately — even a partially damaged cylinder is structurally weakened and provides far less protection.
If you don't know where your keys ended up, assume they could end up in the wrong hands — change the lock before someone else uses them.
Always rekey or change locks after an occupant changes — you can't be certain they haven't made copies of the key before leaving.
Worn locks fail at the worst possible moment — they can stick, jam, or provide easy entry for intruders. If your lock is stiff, rattling, or over 10 years old, it's time for a change.

Common questions about lock change service in the Bronx — answered clearly.
A standard residential deadbolt replacement typically takes 20 to 45 minutes per door. More complex installations — such as high-security cylinders, commercial locks, or reinforced strike plates — may take slightly longer. Our technicians carry all required hardware in their vans, so there is no delay waiting for parts or making a return trip.
Rekeying changes the internal pin configuration of an existing lock cylinder so that old keys no longer work — the hardware itself stays in place. A lock change replaces the entire lock mechanism with new hardware. We recommend a full lock change when the existing lock is worn, low-grade, physically damaged, or when you want to upgrade to a higher security level.
K&D Locksmith NYC installs a range of trusted brands including Schlage, Kwikset, Medeco, Mul-T-Lock, and ASSA Abloy. For maximum residential security, we recommend Grade-1 deadbolts from Schlage. For the highest level of protection with key control, we recommend Medeco or Mul-T-Lock high-security cylinders, which provide pick, bump, and drill resistance and prevent unauthorized key duplication.
Yes. An authorized occupant or property owner should be present when we perform the lock change. This confirms proper authorization to modify the locks and allows us to hand you the new keys in person. For commercial jobs, a manager or authorized representative can be present in place of the owner. We cannot perform a lock change without confirmed authorization from someone on-site.
