Home Rekeying & Lockout Service

When you call 914-670-1446 and report a house lockout, the first thing we do is confirm your location and verify basic ownership or residency — a standard step that protects every homeowner in the neighborhood, including you. Our mobile unit is already stocked with the tools needed for damage-free entry on most residential lock types: spring-latch door knob locks, single- and double-cylinder deadbolts, rim locks, and the mortise lock assemblies common in Larchmont's older Tudor and Colonial homes along Magnolia Avenue and the Manor district. We aim to get you back inside without drilling or replacing hardware whenever the lock design and condition permit it.

Before any work begins, we give you a firm, upfront quote based on the specific factors involved — the lock type on your door, whether it is a standard or high-security mechanism, the time of day, and travel distance to your address. There are no surprise charges once you approve that number. If you have already tried a spare key hidden outside or checked an unlocked window or back door and found no way in, that is exactly the right approach — and calling a professional is the correct next step rather than risking door-frame damage from improvised methods.

Rekeying is the process of reconfiguring the pin tumblers inside an existing lock cylinder so that the old keys no longer work and a fresh set of keys operates the lock. It is not the same as replacing the entire lockset, and in most cases it costs less while delivering the same security outcome. For homeowners in Larchmont who have just purchased a property — especially the older Victorian and Craftsman-era homes near Larchmont Avenue — rekeying is critical because you have no way of knowing how many copies of the original key are floating around from previous owners, contractors, or real estate agents. Our emergency locksmith team carries a full set of rekeying kits for Kwikset, Schlage, Baldwin, and most other major hardware brands, so the work is done on your doorstep, typically in under an hour.

Rekeying makes equal sense after a relationship change, a roommate departure, or any situation where a key has been lost or not returned. We can also rekey every lock in the house to a single master key, eliminating the need to carry a separate key for the front door, side entry, and garage. For properties with a mortise lock — the larger, rectangular mechanism set into the door edge itself, widely found in pre-1960s Larchmont homes — rekeying requires specific cylinder tools and expertise that go beyond basic locksmithing. Our technicians carry mortise-specific equipment and stock replacement cylinders for the most common mortise lock configurations, so you are never told to wait for a part to be ordered.

A mortise lock is built differently from a cylindrical deadbolt or a door knob lock: it sits inside a pocket cut into the door edge and integrates the latch, deadbolt, and sometimes a privacy turn all into one heavy-duty body. That construction makes it exceptionally strong, but it also means that worn internal parts, a sagging door, or years of Westchester humidity can cause it to bind, fail to latch, or stop turning entirely. We repair and rebuild mortise lock assemblies, replace worn cylinders, and — when the body itself is beyond service — install a modern replacement mortise lock that matches the existing door prep so no carpentry is needed.

For newer construction and rentals throughout Larchmont, door knob lock replacement and deadbolt upgrades are among our most-requested residential calls. If your knob lock is the only security on an exterior door, that is a vulnerability worth addressing — knob locks alone are not rated for exterior security use. We carry Grade 1 and Grade 2 deadbolts and can pair a new deadbolt with a rekeyed or replaced knob lock in a single visit. If you are unsure what hardware makes sense for your specific door thickness, frame condition, and security goals, our technician will walk you through the options before anything is installed. Call 914-670-1446 any time — our line is answered live, 24 hours a day, seven days a week.

Larchmont's Boston Post Road corridor — with its mix of boutiques, restaurants, and professional offices — relies on dependable access control just as much as its residential streets do. Our commercial locksmith services extend to businesses of all sizes in the area: master key system design, high-security deadbolt installation, mortise lock service for storefront doors, access control hardware, and emergency after-hours lockout response when a manager or employee is locked out of the office or cannot secure the building at close. Commercial locks face far heavier daily use than residential hardware, and a failed lock on a retail or office door is a liability issue as much as an inconvenience.

Our emergency locksmith response applies equally to residences and businesses. If a door lock fails at 2 a.m. on a Tuesday after a Larchmont storm knocks the power out and your electronic access control stops responding, we will dispatch a technician the same way we would for a noon call on a Sunday. Insured, trained, and carrying the hardware most likely to match your existing system, our technicians do not treat after-hours calls as an exception — it is simply how this service works around the clock.

Every call we take falls somewhere on a wide spectrum of residential and commercial lock needs.

We would rather give you an accurate answer upfront than send a technician who cannot solve your problem.
