Why "more locks means more security" is bad advice for a prewar walk-up in Midtown Manhattan

More locks on your front door does not make your prewar walk-up in Midtown Manhattan harder to break into. In many cases it makes things worse. The deadbolt you added in the middle of the door can actually weaken the frame around the original hardware. The spare key under the mat, the alarm sticker on the window, the fake security camera in the corner of your storefront lobby - none of these do what you think they do. Here is what actually works, and why so many property managers and building owners in New York City are still running on bad information.

Which common security myths put NYC properties at the most risk?

The most dangerous myths are the ones that feel logical. More locks, more security sounds reasonable until you understand that most break-ins in New York City are not forced entries through the lock itself. Burglars kick in doors, pry door frames, or walk through unlocked back doors and service entrances that building owners simply forget about. Adding a second or third lock to a hollow-core door or a weak frame does not fix any of that.

The alarm sticker myth is just as persistent. A sticker from a monitoring company on the window of a Chelsea brownstone or a Financial District storefront does not stop anyone who has seen one before. Experienced criminals recognize outdated branding and ignore it. A real deterrent is a functioning monitored alarm tied to a verified response, not a piece of vinyl.

The fake security camera myth is similar. Dummy cameras fool nobody who has spent five minutes in a building supply store. The dome housing and the blinking red LED are widely recognized. If you are going to install cameras, install real ones. Systems running on Hikvision or Axis hardware, properly positioned and recorded, change behavior because they are credible.

Then there is the spare key in the planter problem. A key under the mat, above the door frame, or inside a fake rock near the entrance of a Murray Hill co-op is not a convenience, it is an invitation. If you need emergency access, a property manager with a master key system is a better answer than a hidden spare.

What security mistakes do building owners in NYC overlook most often?

Back door neglect is one of the most consistent problems we see across commercial properties in all five boroughs. The service entrance, the loading dock door, the rear stairwell exit in a Tribeca loft building - these get treated as secondary concerns. They should be treated as primary ones. A reinforced Sargent 8200 series mortise lock on the front door means nothing if the rear exit can be bypassed with a credit card or a flathead screwdriver.

The first floor risk is real, but the assumption that upper floors are safe is wrong. Buildings in the Upper East Side and across Midtown Manhattan see breaches on higher floors through accessible windows, rooftop access points, and elevator mechanical rooms. Access control is not just a ground-floor problem.

The WD-40 on locks habit is worth addressing because it is genuinely harmful. Building supers across New York City spray WD-40 into cylinder locks to solve a sticking problem. It loosens things temporarily and then attracts grit, which accelerates wear and eventually makes the cylinder easier to manipulate. Use a dry graphite lubricant or bring in a locksmith to diagnose whether the cylinder or the door alignment is the actual problem.

Property managers also underestimate the bump key vulnerability. Standard pin tumbler cylinders found in older buildings - even those with recognized brand names on the housing - are vulnerable to bump key attacks. A brand name on the lock does not guarantee safety. Medeco, Abloy Protec2, and Mul-T-Lock MT5+ cylinders are specifically engineered to resist bumping and picking. These are the products that should be in your key schedule, not whatever came standard when the building was last renovated.

What should a property manager or business owner actually do instead?

Target hardening is the professional framework, and it means layering real deterrents that each require a different bypass method. A criminal presented with a Schlage B-series deadbolt on a reinforced steel frame, a proximity card reader tied to a Lenel or Honeywell access control panel, and a functioning Axis CCTV system with visible signage faces a completely different calculation than one walking past a door with three cheap padlocks and a sticker.

For commercial properties, a properly designed master key system from a manufacturer like Best Access, Corbin Russwin, or Sargent gives building owners control without distributing individual keys to every tenant, contractor, and maintenance worker. Every key that exists is a potential vulnerability. A master key system limits that exposure while keeping access organized and auditable.

Renters often believe they cannot change their locks. In New York City, renters can change locks as long as the landlord receives a copy of the new key. If you are a renter in a walk-up in Hell's Kitchen or a co-op on the Upper East Side and your building's cylinders are original hardware, a rekey or a cylinder upgrade is a reasonable request and in many cases your legal right.

Keyless is not unsafe. The belief that smart locks are a security step backward is outdated. A Yale Assure Lock 2 or a Schlage Encode Plus installed correctly on a solid door with a reinforced strike plate meets or exceeds the physical protection of most keyed locks in residential use. The window of opportunity for a criminal is not wider because there is no keyhole - it is often narrower because there is no key to copy or steal.

If you manage a property in Midtown Manhattan, Brooklyn, Queens, the Bronx, or Staten Island and you are not sure whether your current hardware is doing what you think it is, reach out to Imperial Locksmith and Security through the contact section at imperial-locksmith.com. A real assessment of your existing system costs far less than responding to a breach that a sticker and a hidden key were supposed to prevent.

Frequently asked questions

Can a renter legally change the locks in a New York City apartment?

Yes, renters in New York City can change their locks, but they are required to provide the landlord with a copy of the new key. This applies to most residential leases under New York state law. If you are unsure, ask your building manager before you call a locksmith.

Are keyless smart locks actually less secure than traditional deadbolts?

No. A properly installed smart lock such as the Schlage Encode Plus or Yale Assure Lock 2 meets ANSI Grade 1 standards, the same benchmark as a quality keyed deadbolt. The risk comes from poor installation or cheap hardware, not the keyless format itself.

Do alarm company stickers actually deter break-ins if you don't have an alarm?

Experienced burglars recognize stickers from systems that are no longer active or common enough to be meaningless. A visible deterrent only works when it is backed by real hardware. A monitored alarm, access control system, or CCTV camera is what actually changes a criminal's decision.
