Rekeying & Deadbolt Installation
Moving into a home along Hempstead Turnpike or settling into one of Franklin Square's quiet side streets like Corona Avenue is exciting — but the locks on your new front door have a history you don't know. Previous owners, contractors, real estate agents, and movers may all have had copies of the same key, and there is no way to account for every one. Rekeying those locks and adding a deadbolt is the single most impactful security upgrade a new resident can make in the first 48 hours, and it costs far less time and money than most people expect when a trained mobile locksmith handles it on-site.

Why New Residents in Franklin Square Need Rekeying and Deadbolt Installation First
When a property changes hands in Franklin Square — whether it is a cape-cod rental near the Franklin Square LIRR station area or a split-level on one of the neighborhood's tree-lined residential blocks — the lock cylinder retains every combination ever cut for it. Rekeying changes the internal pin configuration of that cylinder so only freshly cut keys will work, rendering every prior copy useless overnight. It is a faster process than replacing the entire lockset, and in most cases the existing hardware can stay in place. Our technicians arrive with a full kit of replacement pins and springs sized to the most common residential lock brands found throughout Nassau County, including Schlage and Kwikset cylinders, so rekeying is typically completed in minutes per lock.
Adding a deadbolt installation on top of a rekeyed knob lock creates a two-layer barrier that dramatically raises the effort required to defeat your door. A spring-latch door knob lock alone can be slipped with a credit card in seconds. A properly installed, grade-one deadbolt with a hardened steel bolt and reinforced strike plate makes that same technique impossible. For doors facing alleys or secondary entrances, we also recommend a jimmy-proof deadbolt installation — a surface-mounted interlocking rim lock whose design means the bolt cannot be pried away from the frame even with significant lateral force. If you are unsure which option suits your door, call 516-212-6909 and one of our technicians will walk you through the options before you commit to anything.
Mortise Lock and Commercial Locksmith Services for Franklin Square Businesses
Rekeying and deadbolt installation are not exclusively residential concerns. Business owners setting up shop along Franklin Square's commercial corridors frequently need a mortise lock upgrade when taking over a retail or office space. A mortise lock is a multi-function mechanism that sits inside a precisely routed pocket in the door edge, combining a latch, a deadbolt, and sometimes a privacy function into a single robust unit. Because the body of the lock is embedded in the door rather than surface-mounted, it is far more resistant to kick-in and wrench attacks than a standard cylindrical lockset. Our commercial locksmith team handles mortise lock installation, cylinder replacement within existing mortise bodies, and master-key system setup for businesses that need tiered access across multiple doors or suites.
Commercial properties in Franklin Square often operate on schedules that make daytime service appointments difficult. Our 24/7 availability means a commercial locksmith technician can rekey your mortise lock system after closing, install panic hardware on your exit doors before the morning rush, or respond to an emergency locksmith call if a key breaks off in a lock at 2 a.m. We carry commercial-grade mortise lock bodies, high-security cylinders, and the door-reinforcement hardware needed to bring older commercial doors up to current standards — all without forcing you to shut down operations any longer than necessary.
Residential Locksmith Deadbolt Installation: Choosing the Right Hardware for Your Home
Not every door in a Franklin Square home needs the same solution, and one of the most valuable things a residential locksmith visit provides is an honest assessment of what each entry point actually requires. A solid-core front door may be an ideal candidate for a Grade 1 deadbolt installation with a reinforced strike plate and three-inch screws that anchor into the door frame's structural wood rather than just the casing. A side door with a hollow-core slab may need the door itself upgraded before any lock hardware will offer meaningful protection. An interior door with a simple door knob lock might be perfectly adequate as-is. Our technicians evaluate each door before recommending hardware, and we never upsell products that a given situation does not call for.
For sliding patio doors and French doors that are common in Franklin Square's mid-century homes, standard deadbolts are not the right fit. We install multi-point locking bars, auxiliary pin locks, and track blockers that address the specific vulnerabilities of those door types. For apartment-style units or in-law suites within a single-family home, a jimmy-proof deadbolt installation on the secondary entry door gives occupants independent security without requiring a full lock replacement on the shared entryway. Whatever the configuration, our residential locksmith team documents every change made, hands you the new keys on the spot, and leaves no marks on the door frame or finish when a damage-free installation is achievable with the existing door prep.

Frequently asked questions
How much does a local locksmith charge for rekeying and deadbolt installation in Franklin Square?+
There is no single flat rate because the final price depends on several factors: the number of locks being rekeyed or replaced, the grade and brand of deadbolt hardware selected, whether a mortise lock or a jimmy-proof deadbolt installation is involved, the time of day the work is performed, and the travel distance to your address. Emergency locksmith calls made late at night may carry a different rate than a scheduled daytime appointment. What we always do is provide an exact up-front quote after assessing the job — you know the full cost before any work begins, with no add-ons after the fact.
How much is the average locksmith charge for a mortise lock replacement versus a standard deadbolt?+
Mortise lock work is generally more involved than a surface-mounted deadbolt installation because the mortise body sits inside a routed pocket in the door edge, which requires precise fitting and often more time on-site. Standard deadbolt installation on a pre-bored door is comparatively straightforward. The specific cost depends on the lock grade you choose, whether new door prep is needed, and other job-specific factors. We assess the door first and give you a firm price before starting — there is no guesswork on your end.
How much should a locksmith cost in NYC or the Nassau County area, and are your prices the same?+
Pricing in the greater New York metropolitan area, including Nassau County communities like Franklin Square, reflects local labor costs, parts availability, and demand patterns. We do not offer a simple per-lock price because variables like lock type, hardware grade, time of service, and whether an emergency locksmith response is needed all affect the final figure. What we can tell you is that we confirm the full price up front, we do not add hidden fees after the work is done, and every quote reflects the actual scope of the job at your specific address.
Can a locksmith program my key fob, or do I have to go to a dealer?+
Yes, a locksmith can program key fobs for a wide range of vehicle makes and models. Our automotive locksmith technicians carry the programming equipment needed to handle transponder keys and remote fobs roadside in Franklin Square — no dealership appointment required in most cases. The process depends on the specific vehicle year, make, and model, so if you want to confirm your vehicle is supported before scheduling, call 516-212-6909 and we can check on the spot.
What is the difference between rekeying a lock and replacing it, and which one do I need as a new resident?+
Rekeying changes the internal pin configuration inside your existing lock cylinder so that only new keys will operate it — all prior keys become useless. Replacing the lock means removing the entire lockset and installing new hardware. For most new residents in Franklin Square, rekeying is the right first step because it is faster, leaves the existing hardware in place, and addresses the core concern of unknown key copies. Lock replacement makes more sense when the existing hardware is worn, damaged, a low-security grade, or incompatible with the deadbolt or mortise lock system you want to add. Our technicians assess each door and recommend the option that actually fits the situation rather than defaulting to the more expensive choice.
Do you offer 24/7 emergency locksmith service in Franklin Square, and how quickly can a technician arrive?+
Yes — we operate around the clock, every day of the year, including holidays. Our mobile technicians serve Franklin Square and nearby Nassau County communities, so arrival times are generally shorter than they would be for a company dispatching from farther away. Exact response time depends on current call volume and your specific location, but when you call 516-212-6909 we will give you an honest estimated arrival window before you confirm the appointment. We do not route calls to unknown contractors — the technician who comes is part of our own trained and insured team.
