How Much Does It Cost to Have a Deadbolt Lock Installed?

Deadbolt lock installation pricing is built from two core components: parts and labor. On the parts side, the lock hardware itself varies widely. A standard single-cylinder deadbolt — the kind you key from outside and turn a thumb-turn from inside — is a common, cost-effective choice for most Brooklyn apartment doors. Step up to a double-cylinder model (keyed on both sides), a smart deadbolt with app control, or a heavy-duty mortise deadbolt lock, and the hardware cost rises accordingly. Brands like Schlage and Kwikset sit at different price points, and commercial-grade hardware costs more than residential-grade for good reason: it's built to take far more daily use.

On the labor side, a straightforward deadbolt installation on a pre-bored wooden door takes less time than cutting a new mortise pocket into a steel fire door or fitting an entry door knob and deadbolt lock set into a door that's never had either. Factors that shape the final labor quote include door material (wood, steel, fiberglass), whether an existing hole needs to be enlarged or filled, the lock grade being installed, and travel distance to your address within the Brooklyn area. Time of day matters too — emergency or late-night calls involve a different rate than a scheduled daytime appointment. We quote you the exact number before touching anything.

This is the question that trips up a lot of Brooklyn homeowners, especially in older row houses and pre-war buildings. A mortise deadbolt lock is a large, rectangular lock body that fits into a deep pocket (the 'mortise') carved into the edge of the door. You'll find them in many of the older brownstones along Eastern Parkway and on commercial storefronts throughout Bay Ridge. They offer exceptional strength and often combine the latch, deadbolt, and sometimes a door knob lock function into a single unit — which is why a commercial locksmith call for a mortise job takes longer and involves more specialized parts than a simple cylinder swap.

Standard tube-style deadbolts, by contrast, fit through a circular bore hole and are easier to replace or rekey. If your door already has a mortise cutout but the lock body is worn or damaged, a direct replacement keeps costs lower than switching lock types entirely. If you're not sure which type your door uses, a quick photo of your door edge sent to our team can help us arrive prepared with the right parts — call us at (718) 866-3646 and we'll walk you through it before we even leave the shop.

Plenty of Brooklyn residents ask how to change a deadbolt lock on their own, and for a straightforward swap on a standard door with existing holes in good condition, it can be a DIY project. You remove the old lock, drop the new cylinder into the same bore, and secure it with the provided hardware. A 2-pack entry door knob and deadbolt lock set from a hardware store gives you matching hardware for both the knob and the deadbolt at once, which is a smart move for rental unit turnover or a new build.

Where things go sideways: misaligned strike plates, doors that have shifted with age (very common in Brooklyn's older housing stock), stripped screw holes, and steel doors that need special drill bits. A mortise lock replacement is almost never a confident DIY job — the tolerances are tight, the pocket must be precisely cut, and a poor fit compromises the security the lock is supposed to provide. If there's any doubt, a trained locksmith handles the job faster, with the right tools, and with the confidence that the lock is actually secure when done. Our team also handles deadbolt lock replacement on doors where the previous hardware was forced, damaged, or simply too old to function reliably.

A question we hear constantly — especially from new tenants in Crown Heights or new homeowners closing on a place in Canarsie — is: what does it mean to rekey a lock? Rekeying changes the internal pin configuration of your existing lock cylinder so that old keys no longer work. The lock body, the door hardware, and the strike plate all stay in place. Only the tiny pins inside the cylinder are changed, calibrated to match a new key cut. It's faster, less expensive than a full deadbolt lock replacement, and the right call when the lock itself is in good working condition but you simply don't trust who might have copies of the old key.

Full replacement makes more sense when the lock is visibly damaged, when you're upgrading to a higher security grade, or when you're switching from a standard deadbolt to a mortise lock setup. If you're outfitting multiple doors — say, a front entry and a rear gate — a 2-pack entry door knob and deadbolt lock set that can be rekeyed to a single key gives you one-key convenience without sacrificing security. We can rekey multiple locks to match on the same visit, which is a popular option for landlords managing Brooklyn rental properties.

How do I know if a locksmith is legit? It's a fair and important question, especially in a dense market like Brooklyn where fly-by-night operators sometimes advertise low prices and then inflate the bill once they're at your door. Here's what to look for: a real locksmith gives you a firm, itemized price before starting work — not a vague estimate that doubles once the lock is already off the door. They arrive in a marked vehicle, carry proper identification, and can answer specific questions about the work they're doing. A legitimate operation is insured, which protects both the technician and your property.

Our full service menu covers far more than deadbolts. We handle: residential deadbolt installation, mortise lock installation and repair, mortise lock rekeying, entry door knob and deadbolt lock set installation, high-security lock upgrades, smart lock installation, lock rekeying (single or master-key systems), emergency lockout response, broken key extraction, door frame and strike plate repair, lock cylinder replacement, mailbox lock replacement, gate lock installation, padlock installation, window lock installation, car lockout service, automotive key duplication, transponder key programming, ignition lock repair, garage door lock service, commercial deadbolt installation, commercial mortise lock service, access control hardware installation, lock hardware consultation for landlords, and after-hours emergency locksmith response across all Brooklyn neighborhoods. How much should an emergency locksmith cost? For any emergency call — whether it's a lockout at 2 a.m. near the corner of Flatbush and Church or a broken mortise lock on a storefront on 5th Avenue in Bay Ridge — the same rule applies: we give you the price upfront, and it doesn't change.

Let's address both sides of this. On trust: a professional locksmith's quote should be transparent and itemized. When you call us, we ask the right questions — what type of door, what type of lock, what's the situation — so we can give you an accurate number before dispatching. How much does an emergency locksmith cost near me? The cost varies by lock type, time of day, and the complexity of the job, but with Ralph Locksmith Corp, the number we quote is the number you pay. That's how trust is built.

As for how a locksmith opens a locked door — legitimately — the methods depend entirely on the lock type and situation. For a standard pin-tumbler deadbolt during a lockout, a skilled technician uses non-destructive entry tools appropriate to the lock. For a more complex mortise lock or a high-security cylinder, the approach may differ. In all cases, we verify ownership or authorization before proceeding — this is a non-negotiable part of how any responsible locksmith operates. We never share or demonstrate bypass techniques, because that knowledge belongs in trained hands. What matters to you as a homeowner is that we get you back inside safely, without damaging your door or hardware, and then give you an honest assessment of whether your lock needs replacing or is fine to continue using.
