Deadbolt Installation

Not every door is built the same, and the lock that protects it shouldn't be chosen at random. New York City apartments commonly feature steel-clad or solid-wood doors with specific bore-hole measurements, while Queens row houses and detached homes in the outer boroughs often have older wooden door frames that require precise fitting to avoid weakening the door's integrity. Our technicians assess your door thickness, frame condition, existing hardware cutouts, and strike-plate depth before recommending a lock grade. We regularly install Schlage, Kwikset, and Medeco deadbolts, as well as mortise lock systems — a format widely used in older New York City buildings where the lock body sits recessed inside the door rather than surface-mounted. A mortise lock offers exceptional resistance to lateral force and is often the correct choice for pre-war apartment doors that weren't designed to accept a standard cylindrical bore.

For renters and co-op owners dealing with narrow door stiles or double-door setups, a jimmy proof deadbolt installation is frequently the best answer. A jimmy proof deadbolt — also called an interlocking deadbolt — mounts on the surface of the door and frame, making it ideal when drilling a full bore hole isn't possible or permitted. Our team carries jimmy proof models suited to both wood and metal doors, and we can explain which option fits your lease terms and building rules before we start any drilling.

A proper deadbolt installation is more than dropping a lock into an existing hole. Our technicians start by verifying the door is square in its frame — a common issue in older New York buildings where settling and humidity have shifted alignment over decades. A misaligned door causes premature wear on the bolt mechanism and can leave visible gaps that undermine security. Where necessary, we adjust strike plates, reinforce door frames with steel inserts, and ensure the bolt throw engages cleanly and fully. For doors that currently have only a door knob lock with no secondary deadbolt, we drill a new bore hole to the correct diameter and depth, then fit the deadbolt so both locks operate independently without interfering with each other.

We work damage-free where the door and frame conditions allow. That means using precise hole saws and chisels rather than destructive methods, and taking care to preserve door finish and frame paint — something that matters especially in rental apartments where tenants are responsible for returning the unit in good condition. After installation, every lock is tested multiple times for smooth operation, and we walk you through using any new key sets or thumbturn mechanisms before we leave.

For residents and property owners who want the highest level of door security, a mortise lock fitted by an experienced commercial locksmith or residential specialist offers a level of structural integration that surface-mounted locks simply can't match. The mortise lock body is set into a routed pocket in the door edge, distributing force across a much larger area of the door. This makes it extremely difficult to defeat through blunt impact — a real concern on ground-floor apartments in busy neighborhoods like Jackson Heights, Woodside, or Long Island City's industrial-residential mix near the waterfront. We carry multi-point mortise systems that engage the door at the top, middle, and bottom simultaneously, which is particularly valuable for thin or lightweight doors.

Beyond mortise lock options, we also install high-security cylinders with anti-pick, anti-drill, and anti-bump pins for customers who want to retain an existing lock body but upgrade its resistance. Restricted keyways — where copies can only be cut by our team — add another layer of key control, useful for landlords managing multiple units or homeowners who've recently had a key go missing. If you're unsure which direction makes sense for your door and threat model, call (347) 960-2142 and one of our technicians can talk you through the options before you commit to anything.

The final cost of a deadbolt installation depends on several variables: the type of lock selected (a basic single-cylinder unit versus a full mortise lock system), whether new bore holes need to be cut, the condition of the existing door frame, travel distance to your location, and the time of day — after-hours and emergency locksmith calls do carry a different rate than standard daytime appointments. We confirm an exact price up front before any tool touches your door. There are no hidden call-out fees added quietly at the end. What we quote is what you pay.

Our mobile units are stocked with hardware and tools to handle most installations in a single visit. As a 24/7 emergency locksmith team, we respond to urgent situations — a damaged lock after an attempted break-in, a lock that's seized and won't turn, a newly moved-in tenant who needs the locks re-keyed or fully replaced before their first night. Long Island City's mix of high-rise rentals, converted warehouses, and historic row homes means our technicians have encountered nearly every door configuration in the New York market. That depth of local, hands-on experience is what separates a correct installation from one that looks fine but fails under pressure. Call (347) 960-2142 any time — we answer 24/7 and can usually have a technician at your door faster than you'd expect.
