Fast, Reliable Lock Installation & Rekey Across Yonkers
Lock installation and rekeying in Yonkers means working with hardware most suburban locksmiths never touch: pre-war mortise locksets, cast-iron vestibule entries, and original cylinders that have been turning for eighty or ninety years. A standard rekey on a cylindrical Kwikset runs $25-$45 per cylinder. A mortise cylinder rebuild on a 1920s Park Hill apartment door runs $65-$120 per cylinder, quoted in writing before we start. We’re Novak Lock & Security, independently owned and operated since 2002, and our crews serve Yonkers neighborhoods every day. Call (331) 310-8471 and a live person answers, 24/7.
Why Novak Lock & Security Is Yonkers’s Preferred Lock Installation & Rekey Company
Yonkers is not a typical Westchester town. The southwestern and downtown neighborhoods, particularly around Getty Square, Park Hill, and Nodine Hill, are dense with 3-to-6-story brick apartment buildings from the 1910s through 1940s. Those buildings still run original mortise locksets. A technician who only knows modern cylindrical hardware cannot service them properly. Our techs rebuild antique mortise cylinders and box strikes at near-urban NYC scale because Yonkers demands it. We stock parts for obsolete cylinder formats that big-box stores stopped carrying decades ago.
Every Novak technician is background-checked, uniformed, and works under The Haven Standard, the same documented quality framework applied across all ten Haven brands. Daniel Novak, who leads Novak Lock & Security, built the company on one rule: the price quoted on the phone is the price on the invoice. Haven Standard Clause 1. No exceptions, no add-ons at the door. Since 2002 we’ve installed or serviced 60,000+ locks, keys, and systems, every one with a written price before we started and a documented photo record when we left.
Our Lock Installation & Rekey Services in Yonkers
Our Lock Installation & Rekey team handles the full spectrum, from entry-grade rentals in Nodine Hill to high-security cylinders on riverfront properties near the Hudson. Here’s what Yonkers homeowners and building superintendents call us for most.
Smart Lock Installation
Installing a smart lock on a pre-war door is not a drop-in job. The existing mortise lock body sits inside the door, not on the surface, so most consumer smart locks require either an adapter plate or a careful retrofit that preserves the original trim. In Park Hill and Getty Square buildings, we commonly install smart locks that work with the existing mortise case rather than replacing it. The job typically runs $180-$320 in Yonkers, including the lock, labor, and programming. We also handle commercial smart lock systems for multi-unit buildings where superintendents want audit trails on common-area doors.
Keyless Entry
Keyless entry in Yonkers’s rental stock usually means one of two things: a keypad deadbolt on an apartment door for tenant turnover, or an electric strike tied to an intercom system at the building entry. The intercom-to-electric-strike systems in Yonkers’s aging mid-rises fail constantly, and we service those strikes and their wiring. For apartment doors, a keypad deadbolt installation runs $140-$260. For vestibule electric strike replacement on an older building, expect $220-$400 depending on the strike model and whether the intercom wiring needs repair.
Keypad Lock
Keypad locks are the practical middle ground for Yonkers homeowners who want keyless entry without Wi-Fi dependencies. They hold up better than smart locks in the Hudson River humidity, but the keypad contacts still need occasional cleaning when corrosion builds. We install and rekey keypad deadbolts throughout Yonkers, including the eastern side’s 1940s-1960s colonials and split-levels where standard cylindrical prep makes the job straightforward. A keypad deadbolt installation runs $110-$190 in Yonkers.
Biometric Lock
Biometric locks use fingerprint or facial recognition to open. They’re popular on Yonkers rental office spaces and private home offices. On a pre-war door, biometric locks face the same retrofit constraints as smart locks: the mortise case sits inside the door, so installation is more involved than a surface-mount deadbolt. We install biometric locks on both mortise-prep and standard-prep doors in Yonkers. A fingerprint deadbolt installation runs $180-$300; a full biometric mortise lock conversion runs $350-$600 depending on whether we rebuild the existing case or replace it.

Trusted Brands We Service in Yonkers
We’re factory-authorized on Medeco, Mul-T-Lock, and Abloy high-security cylinders, and we service the full spectrum down to entry-grade Schlage and Kwikset. For Yonkers’s older buildings, we also stock replacement parts for Baldwin mortise locks and Sargent cylinders, the two brands most common in pre-war multi-family construction. That matters when a 1930s door needs a new cylinder and you don’t want to replace a cast-iron lock case that still has decades of life in it. We keep those parts in local stock so Yonkers calls get same-visit turnarounds instead of week-long special orders.
Common Lock Installation & Rekey Problems We See in Yonkers Homes
- Hudson River corrosion seizes windward vestibule cylinders. The elevated humidity along Yonkers’s western edge accelerates corrosion inside lock cylinders and on strike plates. By winter, keys snap off or won’t turn at all. We pull the cylinder, clean or replace the internal pins and springs, and rekey to a fresh key.
- Original mortise cases crack during freeze-thaw cycles. Yonkers’s hard winters put real stress on cast-iron lock cases in older brick buildings, especially where door alignment has shifted over decades. A cracked mortise case is a replacement job, not a rekey.
- Obsolete cylinder formats block modern deadbolt retrofits. Many pre-war Yonkers doors use cylinder formats no longer manufactured. A modern deadbolt won’t simply drop in without cutting into the original door and jamb, which often voids historical trim. We source and rebuild the original format instead.
- Master key system compromise from tenant turnover. Building superintendents in Yonkers’s older multi-family stock routinely manage master-key systems spanning 20-80 units. High tenant turnover means those systems get compromised and need full rekey cycles far more often than ownership-stable buildings. We handle that pinning work at commercial volume.

FAQs - Lock Installation & Rekey in Yonkers
Yes, in most cases. If the mortise case is intact and the cylinder threads are not stripped, we pull the cylinder, re-pin it to a new key, and reinstall it. The only time you need a full lockset replacement is when the cast-iron case itself is cracked, which happens in Yonkers’s hard freeze-thaw cycles, usually where door alignment has shifted. Call (331) 310-8471 and describe the door; we’ll tell you what’s likely before we even schedule.
Rekey every time a tenant moves out, and re-pin the entire master system whenever a master key goes missing. In Yonkers’s multi-family stock, where buildings of 20-80 units are common and turnover is constant, we recommend superintendents keep a rekey log and pre-schedule rekeys during turnover season, which runs heaviest from April through September. A full master-key rekey for a 30-unit building runs $900-$1,800 depending on cylinder count. Call (331) 310-8471 for a written quote.
Not necessarily. Hudson River humidity corrodes the internal pins and springs long before the lock case fails. We pull the cylinder, inspect the pin stack, and often find the problem is three or four corroded pins, not the whole lock. We replace the pins, rekey the cylinder, and the lock turns again. If the case has cracked from freeze-thaw stress, that’s a replacement job, and we’ll tell you that in writing with a photo record of what we found.
You do not need to change the door. We install smart locks that work with the existing mortise case using adapter plates, so the original cast-iron trim stays intact. The job costs more than a standard deadbolt smart lock installation because the mortise retrofit is more involved, but it’s far cheaper than replacing a pre-war door and frame. In Yonkers, expect $250-$400 for a mortise-compatible smart lock installation.
Rekeying changes the internal pins so old keys stop working and new keys work. Replacing swaps the entire lock body and cylinder. In Yonkers’s pre-war buildings, the cast-iron mortise case inside the door is often better made than anything sold today, so we rekey it whenever the case is intact. We replace only when the case is cracked, the threads are stripped, or the landlord wants a different lock grade entirely. Call (331) 310-8471 and we’ll tell you which applies to your door.
