If you live in a Brooklyn walk-up off Flatbush Avenue or a converted brownstone in Park Slope, you have probably stood in your hallway staring at your door hardware and wondered whether what you have is actually enough. The door knob lock that came with your apartment feels flimsy, the super installed a deadbolt years ago, and nobody has explained how those two pieces of hardware actually work together — or whether they are doing the job at all. This guide breaks it down in plain terms so you can make a smart decision about your door before a problem forces the decision for you.
Understanding the difference between a knob lock and a deadbolt is not just a hardware trivia question — in a dense urban borough like Brooklyn, where buildings share walls, vestibule doors are propped open constantly, and exterior doors face real daily stress, the combination of locks on your door is a genuine safety issue. Here is what each lock type actually does, where each one falls short, and how the right combination — including a properly installed mortise lock — meets the security demands of a real NYC apartment.
Frequently asked questions
Who are some reputable locksmiths in Brooklyn, New York?+
A reputable locksmith Brooklyn residents can trust will show up in a marked vehicle, identify themselves clearly, provide a written price before starting work, and carry insurance. At Top Brooklyn Locksmith, we are insured, operate 24/7 with a local mobile team, and specialize in residential, commercial, and emergency locksmith services across every Brooklyn neighborhood — from Bay Ridge to Greenpoint. Ask any locksmith you call whether they will confirm the full price before touching your lock. That single question filters out most bad actors quickly.
Is a door knob lock enough to secure my Brooklyn apartment?+
On its own, no. A door knob lock uses a spring-latch bolt that can be bypassed without a key by someone who knows what they are doing — and unfortunately, searches for how to pick a door knob lock are common enough to confirm that knowledge is widely available. For an exterior apartment door in Brooklyn, you need at minimum a keyed deadbolt alongside your knob lock. A better solution for older Brooklyn building doors is a mortise lock, which combines latch and deadbolt functions in a single heavy-duty unit that is far more resistant to both picking and forced entry.
How much does a locksmith cost in Brooklyn, and what affects the price?+
There is no single flat rate because several real factors move the number: the type of lock being serviced (a mortise lock installation is more involved than a basic knob lock rekey), the grade and brand of hardware selected, whether the door frame needs reinforcement or new holes need to be cut, the time of day the job is scheduled, and the travel distance for our mobile unit. What does not change is our process — we confirm an exact up-front price with you before any work begins. You always know what you are agreeing to before we touch anything.
What is a mortise lock and do I need one for my Brooklyn apartment?+
A mortise lock is a heavy-duty lock assembly that fits inside a rectangular pocket cut into the edge of your door, combining a latch bolt and a keyed deadbolt in one unit. It is the standard hardware on commercial doors and older pre-war residential buildings throughout Brooklyn because it is significantly more durable and secure than a surface-mounted deadbolt paired with a separate knob lock. If your door currently has mismatched or worn hardware — especially in an older brownstone or a high-traffic building entrance — a mortise lock installation is often the most sensible long-term upgrade. Our team handles mortise lock installation, repair, and replacement across Brooklyn. Call (631) 380-4138 to schedule an assessment.
