You locked your apartment door this morning, heard the knob click, and walked away confident. But if that door knob lock is the only thing standing between your home and an intruder, you may be far less protected than you think. A standard knob lock — the kind found on millions of New York City apartment and brownstone doors — was designed primarily for privacy, not security. Understanding why that matters, and what to do about it, is the first step toward genuinely protecting your space.
This guide breaks down exactly why a door knob with lock alone falls short in a city like New York, what upgrade options actually work, and how Cloisters Locksmith NYC can help you make a smart, lasting improvement — whether you live on the Upper West Side, in Astoria, or along a quiet Carroll Gardens block.
Frequently asked questions
Is a door knob lock enough security for a New York City apartment?+
In most cases, no. A door knob lock is designed for privacy and light-duty security, not to resist forced entry. The mechanism is exposed on the outside of the door and relies on a spring latch that can be defeated without touching the key cylinder. For genuine protection, a Grade 1 deadbolt — or a mortise lock if your door is compatible — should be installed alongside the knob lock, with a reinforced strike plate anchored into the wall stud. Our team can assess your specific door and recommend the right combination for your building type.
What is a mortise lock and do I need one?+
A mortise lock is a complete locking assembly — combining a latch bolt, a deadbolt, and often additional security features — housed in a single unit that is recessed into the body of the door. Because the hardware is embedded rather than surface-mounted, it is far more resistant to kick-in and forced entry than a standard knob lock or even a surface-mounted deadbolt. Mortise locks are common in New York City's pre-war buildings and are an excellent choice for brownstones, townhouses, and any solid-wood door with sufficient thickness. If you're not sure whether your door can accommodate a mortise lock, our locksmiths can evaluate it on-site.
How much does a local locksmith charge for a lock upgrade in NYC?+
The final cost depends on several factors: the type of lock being installed (a deadbolt swap is simpler than cutting a mortise pocket), the grade and brand of hardware you choose, whether any door frame reinforcement is needed, the time of day, and travel distance to your location. There is no single flat answer that is honest for every job. What we can promise is that Cloisters Locksmith NYC will give you a confirmed, exact price before any work starts — so you know exactly what you're agreeing to.
What should I do if I'm locked out of my apartment?+
First, check whether you have a spare key with a trusted neighbor, family member, or building superintendent — this is the fastest resolution that costs nothing. If your building has a super or property manager on call, contact them before anything else. If none of those options are available, call a professional locksmith rather than attempting to force the door, which can damage the frame, the lock, and potentially expose you to liability. Cloisters Locksmith NYC is available 24 hours a day at 646-760-8361 — we can typically reach most NYC locations quickly, verify your right to access the property, and get you inside without unnecessary damage to your door.
