5 Ways a Locksmith Can Improve Security for NYC Residents

Post shared with us by a LockSmith from NYC

The 2 AM calls follow a pattern. Somebody kicked in an apartment door, the tenant is standing in the hallway with a cop, everybody assumes the lock failed. Then I get down on one knee with a flashlight and find the same thing I found last month in a different zip code: a decent deadbolt thrown into a strike plate held by two three-quarter-inch screws that never reached past the trim. The lock held fine. The half inch of pine around it did not.

Fifteen years of these calls across this city and the lesson has stayed stable. People buy locks. Break-ins go through everything around the lock.

The Door Assembly Fails Before the Cylinder Ever Gets Tested

Start with the strike plate, the metal rectangle the bolt slides into, because this is the cheapest fix in all of home security. The screws that ship in the box are stubs. Swap them for 3-inch screws that bite through the jamb into the wall framing behind it, add a reinforced plate if the door takes a heavy-duty box, done. Twenty minutes, a few dollars and a kick that would have opened the door now bruises a heel instead.

Hinges next. On doors that swing outward, the hinge pins face the world, which means three tapped-out pins can take a locked door off like a cabinet panel. Set screws or security studs in the hinges close that hole. I check hinge exposure on every job now because of how often the fanciest lock on the block sits three feet from this exact oversight.

Then the slab itself plus how it grabs the frame. A standard American residential setup locks at one point, the deadbolt, so all the force of a kick concentrates right there. The multi-point systems that come standard on European exterior doors engage the frame at several heights at once, top, middle, bottom, which spreads an impact across the whole assembly instead of one screwed-on plate. For street-level entries, garden apartments, anywhere a door faces the public directly, that construction difference matters more than any cylinder upgrade. The brownstone crowd tends to resist until I point out the originals on their 1900s doors were mortised into hardwood by people who assumed horses outside, not battery drills.

The Burglary Numbers Are Falling. My Phone Is Not Ringing Less.

Fair is fair, the city’s trend is real. NYPD’s year-end count put burglary at 12,777 complaints across the city in 2025, down around 4 percent and the first half of 2026 dropped a further 16 percent, one of the steepest midyear declines the CompStat era has recorded. Anyone telling you the sky is falling in New York is selling something.

What the citywide average cannot tell you is anything about your door. Burglary here is block-by-block, building-by-building and the attempts that do happen have not gotten politer. Most are fast and physical, a kick, a pry bar at a gap, a reach through a flimsy window latch. The movie stuff, the tension wrench and the picks, is rare on residential jobs because force is quicker and burglars are practical people. Which reorders the shopping list: frame, strike, hinges, window latches first, lock sophistication second.

When the lock itself is the weak point, the grading system does the talking. Locks carry ANSI grades, 1 through 3, Grade 1 built for the abuse commercial doors take, Grade 3 built for a price point. A Grade 1 deadbolt properly installed into a reinforced strike is a different object from what most hardware aisles sell as standard, at a difference of maybe forty dollars. Cheapest insurance in the trade after the screws.

Smart Locks Earn Their Place Here, With Two Warnings Attached

I install keyless systems weekly and the case for them in this city is honest. Dog walker at 2, delivery at 4, in-laws landing early, a code for each, revoked whenever, no key copies floating around the neighborhood. Property managers love the entry logs plus the ability to cut access the day a tenant leaves instead of re-keying the day after. For buildings with turnover, the math works fast.

The warnings come from my winter call log. Batteries die, cold speeds it up and every January brings a run of people locked out by a dead 9-volt. Keep the mechanical key override, know where that key lives, replace batteries on a calendar instead of on faith. Second warning: a smart lock bolted into a weak frame is a phone app attached to the same kickable door. The electronics change convenience. The carpentry still decides the break-in.

Rekey the Day You Move In, Not the Month After

Whoever lived in your place before you still has a key. So does their ex, their dog sitter, the contractor from the kitchen renovation. Rekeying, swapping the pins inside the existing cylinder so old keys die, costs a fraction of new hardware and takes minutes per lock. It belongs on the moving-day list next to the utilities call and after any roommate change or lost key ring it belongs there again.

One safety note I give unprompted. Double-cylinder deadbolts, the kind needing a key on the inside too, tempt people with glass near the door. Fire codes restrict them in many situations for a plain reason: in smoke, at night, nobody finds a key. There are better answers for glass-adjacent doors than locking yourself in with your own security.

If you take one thing from a locksmith instead of a lock company: walk your own door tonight. Push on the frame, look at the strike screws, check which way the hinges face, try the window latches. Ten minutes of looking finds what fifteen years of 2 AM calls keep finding for me, usually before the city’s fastest-moving trade finds it first.
