I lost my only key to my Williamsburg apartment - what are my options?

If you lost your only key to your Williamsburg apartment, brownstone, or storefront, you have more options than you think - and most of them do not require a frantic search for a 24-hour phone dispatcher. The short answer: call a local same-day locksmith to open the door without destroying the lock, then get a spare key cut immediately so you are not back in this spot next week.

Here is exactly how it works, what a locksmith will actually do at your door, and what you should know before anyone touches your lock.

What does a locksmith actually do when you are locked out of your apartment?

The first thing a locksmith does is assess the lock. In Williamsburg and Bed-Stuy, most prewar walk-ups and brownstones still run Kwikset or Schlage deadbolts, sometimes original hardware that has been in place for decades. Newer buildings in Greenpoint and East Williamsburg often have Medeco or Mul-T-Lock cylinders, which are high-security and significantly harder to pick.

For a standard Kwikset or Schlage deadbolt, a trained locksmith will attempt lock picking first. This is non-destructive. The lock is manipulated open using tension tools and picks, the cylinder stays intact, and you are inside in minutes. No damage, no replacement cost.

If the lock resists picking - common with Medeco M3 or Mul-T-Lock MT5+ cylinders, which use sidebar mechanisms specifically designed to defeat picking - the locksmith moves to lock bypass techniques. This might mean shimming, decoding, or using a bypass tool suited to that specific lock model.

Drilling is a genuine last resort. A locksmith will only recommend drilling when the lock cannot be opened any other way, or when a snapped key or broken key is jammed deep enough in the cylinder that extraction tools cannot reach it. Even then, only the cylinder is drilled, not the door or the housing. The cylinder gets replaced afterward.

One thing a real neighborhood locksmith will never do is recommend drilling a standard lock on a first visit. If a technician shows up and immediately reaches for a drill, that is a red flag.

What happens if a key snapped in the lock or broke off in the ignition?

A snapped key or broken key in the lock is its own situation. It is not the same as a simple lockout, and it should not be treated as one.

For a broken key in a door lock - say a deadbolt on a Bushwick storefront or a co-op in Downtown Brooklyn - a locksmith uses a broken key extractor. This is a small hooked tool designed to catch the serrations on the key fragment and pull it out without pushing it deeper. The key has to be positioned correctly for this to work. If someone has already tried to push the fragment out from the other side or used the wrong tool, extraction becomes harder.

Once the fragment is out, the locksmith can cut a new key from the lock itself using a code-cutting machine, or decode the existing cylinder and cut to code. You do not necessarily need to rekey the lock unless the lost key is also unaccounted for, in which case a rekey is the smart call anyway.

A broken key in an ignition is a separate job that crosses into automotive locksmith territory. Most locksmiths who handle commercial and residential work do not carry the specialty tools for ignition extraction. Be specific when you call so you get the right technician sent to you.

One more situation worth knowing: a frozen lock. In a Brooklyn winter, especially on older buildings in Greenpoint or East Williamsburg where the door faces north, moisture gets into the cylinder and freezes. The key goes in but will not turn. Do not force it - that is exactly how keys snap. A locksmith can thaw the cylinder or apply a graphite lubricant. A can of WD-40 is a temporary fix at best and can attract dirt over time. Proper cylinder lubricant or a product like Kryptonite Bike Lock Lube works better for long-term maintenance.

How do you prevent losing your only key from turning into a crisis again?

The answer is simple and most people skip it: cut a spare key the same day the problem gets resolved.

At B & G Hardware in Williamsburg, key duplication happens at the counter while you wait. Bring your key in and walk out with one or two copies in under five minutes. For standard Kwikset KW1 or Schlage SC1 keyways, the cut is straightforward. For Medeco or Mul-T-Lock keys, duplication requires a registered key card and can only be done by an authorized dealer - which is something to ask about when you have your lock installed.

If you are a landlord or super managing multiple units in a Bed-Stuy brownstone or a Williamsburg rental building, a master key system is worth the investment. A Medeco or Mul-T-Lock master key system lets you carry one key for all units while tenants have individual keys that do not cross over. It also protects against bumping - a technique where a specially cut key is struck to momentarily align the pins and open a lock. High-security cylinders with anti-bump pins, like the Schlage B60N with a Primus cylinder or any Mul-T-Lock deadbolt, resist this effectively.

For small business owners with a storefront or office in Downtown Brooklyn or Williamsburg, consider a smart lock like the Schlage Encode or the Yale Assure SL. You can issue codes instead of physical keys, revoke access instantly, and never deal with a lost key situation again. These locks still have a physical cylinder as a backup, which a locksmith can service or rekey.

Frequently asked questions

How fast can a locksmith reach me in Williamsburg or Greenpoint for an apartment lockout?

Most calls in Williamsburg, Greenpoint, and Bushwick get a locksmith on-site within 30 to 45 minutes. If you can walk to 210 Roebeling St in Williamsburg, you can skip the wait entirely and handle it at the counter.

Will a locksmith have to drill my lock if I'm locked out?

Drilling is a last resort. A skilled locksmith will first attempt non-destructive entry using lock picking or bypass techniques. Drilling only happens when the lock is a high-security model that resists picking, or when a snapped key has completely blocked the cylinder.

Can I get a spare key made after a lockout so this doesn't happen again?

Yes, and you should do it the same day. At B & G Hardware in Williamsburg, keys are cut while you wait at the counter. Bring your working key or have the locksmith cut a new one from the lock itself after the lockout is resolved.
