Your home security is only as strong as the locks protecting it. K&D Locksmith NYC specializes in professional deadbolt installation and security upgrades in Westchester Square — from replacing worn-out builder-grade hardware with ANSI Grade-1 deadbolts, to installing high-security Medeco and Mul-T-Lock cylinders and modern smart lock systems. Same-day service, upfront pricing, and licensed technicians.
Westchester Square is a historic commercial and residential neighborhood in the southeast Bronx, anchored by the old Westchester Square — a former town center that still gives the area its distinct character. The neighborhood is home to a mix of attached row houses, private homes, and multi-family buildings along streets like Westchester Avenue, Commerce Avenue, and St. Peter's Avenue. Like many dense urban neighborhoods, home security here matters — and the first line of defense is always the deadbolt on your front door.
K&D Locksmith NYC installs, replaces, and upgrades deadbolts for Westchester Square homeowners, renters, and property managers. Our technicians carry a full inventory of ANSI Grade-1 deadbolts, high-security cylinders from brands like Medeco and Mul-T-Lock, and smart lock systems — so we can complete your installation in a single same-day visit with no waiting on parts. We assess your door, recommend the right hardware for your situation, and install it cleanly with no gaps, wobble, or misalignment.
We are fully licensed and insured, serving all of the Bronx. Explore all of our Bronx locksmith services.
Not all deadbolts offer the same level of protection. Here's how the three main grades compare across the security features that matter most.
Basic residential — typically builder-grade locks installed in new construction.
Highest ANSI residential rating — the standard we install for most Westchester Square homes.
Best ValueMedeco, Mul-T-Lock — engineered for environments requiring the highest protection.
Every security upgrade we offer is performed by licensed technicians using quality hardware that lasts.
New deadbolt installation for doors that don't currently have one, or same-door prep replacement of an existing deadbolt with a higher-grade model. Done right the first time.
Replace worn, damaged, or outdated lock hardware with modern Grade-1 equipment. We remove the old lock, install the new one, and test the fit and function before we leave.
For homeowners who want the ultimate protection, we install high-security cylinders from Medeco and Mul-T-Lock — featuring drill-resistant steel, anti-pick pins, and patented key control.
When the lock hardware is still in good condition, rekeying is the smart, cost-effective alternative to a full replacement. We reconfigure the cylinder so only new keys work.

Everything you want to know before scheduling your deadbolt installation or security upgrade.
For residential use in Westchester Square, we recommend ANSI/BHMA Grade-1 deadbolts at a minimum. Grade-1 is the highest standard for residential locks — it offers superior pick resistance, bump resistance, and long-term cycle durability compared to the Grade-2 or Grade-3 hardware often found in builder-grade homes. For properties requiring maximum security, we also install high-security deadbolts from Medeco and Mul-T-Lock, which add drill resistance and patented key control.
A standard deadbolt replacement — swapping an old deadbolt for a new one in the same door prep — typically takes 20 to 30 minutes. If we need to drill a new hole for a deadbolt where one didn't exist before, that can take up to 45–60 minutes. Either way, same-day service is the norm throughout Westchester Square and surrounding Bronx neighborhoods.
Grade-1 deadbolts meet ANSI standards for residential security and resist most common attacks including picking and bumping. Medeco and Mul-T-Lock high-security locks go several steps further: they feature drill-hardened steel inserts, precision-machined cylinders with extremely tight tolerances that resist picking, and patented keyways with restricted key control — meaning keys can only be duplicated with authorization. They're ideal for Westchester Square homeowners wanting maximum peace of mind.
Absolutely. We install a wide range of smart locks that replace or augment your traditional deadbolt — including keypad entry, Bluetooth-enabled smart locks you control from your phone, and Z-Wave connected locks for smart home integration. Most smart locks fit standard 2-1/8-inch door bores, so installation is typically straightforward. We configure the lock, set up your access codes, and test everything before we leave.
Yes — same-day deadbolt installation is our standard in Westchester Square, Bronx. Because we stock Grade-1 deadbolts and high-security hardware directly in our service vans, there's no waiting on parts to be ordered or shipped.
