Rekeying & Lock Changes

Rekeying means a technician disassembles your existing lock cylinder and replaces the internal pins and springs so that your old key no longer operates it. A brand-new key — cut on the spot — is the only one that will work going forward. The lock hardware itself stays in place, which is why rekeying is often the most efficient path when the locks are in good physical condition but key control has been compromised. Our technicians routinely rekey Schlage, Kwikset, and other common residential cylinder formats, and we can key multiple locks alike so one key opens every door in your home. This is a popular request among homeowners along Whippany Road who are finishing a renovation and want to retire all the contractor keys at once.

Replacing a lock — swapping out the entire door knob lock, deadbolt, or mortise lock assembly — makes more sense when the hardware is worn, damaged, or simply not up to the security level you want. A standard door knob lock alone offers minimal resistance to forced entry; pairing it with a Grade 1 deadbolt dramatically changes the equation. Our technicians install new hardware damage-free where the existing door prep allows, fitting replacement locks cleanly so the door operates smoothly and the finish looks intentional, not patched.

A mortise lock is a full-body lock mechanism that sits inside a recessed pocket — the mortise — cut into the edge of the door. Because the lock body is embedded rather than surface-mounted, mortise locks are inherently more resistant to kick-in and pry attacks than a standard cylindrical deadbolt. They are common in older Whippany homes built in the mid-twentieth century, in commercial storefronts, and in multi-unit residential buildings throughout Morris County. As a commercial locksmith resource for the area, we service mortise lock hardware regularly — rekeying cylinders, replacing worn case mechanisms, installing new mortise sets, and sourcing hard-to-find replacement parts for legacy assemblies.

If your building has a mortise lock that has become stiff, fails to latch reliably, or simply needs its cylinder rekeyed after a tenant or employee change, call us at 973-566-5581 and we will dispatch a trained technician to your location. Mortise lock work requires familiarity with the specific case geometry and lever or knob trim of your existing hardware — our team brings that hands-on experience to every job, whether it is a single-family home near Troy Hills or a retail unit in a commercial strip along Route 10.

The most common upgrade we perform is removing an aging door knob lock — often a builder-grade knob with a thin latch bolt — and installing a properly matched deadbolt alongside it, or replacing both with a single high-quality handle-set that integrates a deadbolt throw into one unit. For exterior doors, we strongly recommend a minimum Grade 2 deadbolt, and in many situations a Grade 1 unit with a reinforced strike plate anchored with three-inch screws. Our technicians will assess your door thickness, backset distance, and cross-bore size before recommending hardware, so what we install fits your specific door without hacking or shimming.

For Whippany residents who want keyless convenience without sacrificing security, we also install electronic deadbolts and smart lock conversions that retain your existing deadbolt mortise and simply replace the cylinder with a motorized or push-button mechanism. These work especially well for homeowners who manage short-term rentals or frequently need to grant temporary access to family members. Whatever direction you choose, we confirm the up-front price — factored by lock grade, hardware brand, any additional parts needed, and the time of your call — before a single screw turns.

Beyond planned rekeying appointments, we respond to urgent situations around the clock. If you discover a lock has been tampered with after returning home late, if a commercial door knob lock fails mid-shift at your Whippany business, or if a property manager needs emergency re-keying after an eviction, our mobile units are already on the road. Being a true emergency locksmith service means we do not forward calls to an answering service at night — a real technician picks up, gathers the details, and dispatches immediately.

For commercial clients — office suites, warehouses, medical practices, and retail spaces throughout the Whippany area — we handle master key system planning, mortise lock replacement on heavy-use commercial doors, and coordinated rekeying across multiple suites so that management keys and tenant keys are properly segregated. Ownership verification is a standard part of every commercial call; we confirm authorization before beginning any work, which protects both you and the integrity of your property. To schedule service or get an immediate response, call 973-566-5581 — we answer 24/7.

Pricing for rekeying and lock change work is not one-size-fits-all, and we think it is important to be transparent about what shapes the quote you receive. The primary factors are the type and grade of lock involved — rekeying a basic cylindrical deadbolt involves different labor and parts than servicing a multi-point mortise lock or installing a Grade 1 electronic deadbolt. Time of day matters as well; after-hours and overnight emergency calls reflect the cost of having a trained technician available at 2 a.m. Travel distance from our base in the Whippany area and the quantity of locks being serviced in a single visit also affect the total. If replacement parts or new hardware are needed, those are itemized clearly.

What we commit to is this: before any work begins, your technician states the exact price and answers any questions you have. There is no pressure, no hidden labor fee added at the end, and no bait-and-switch after we arrive. If circumstances change mid-job — for example, a lock that turns out to need a full replacement rather than a rekey — we explain what was found and confirm the revised price before proceeding. This approach keeps the relationship straightforward and earns the kind of repeat calls we get from Whippany homeowners who have used us once and return whenever a lock situation comes up.
