We’ve been working in Scarsdale for decades. We know the heavy oak doors on the Tudor Revivals near Saxon Woods, the Colonial Revivals off Post Road with their original brass escutcheons, and the French Norman estates in Heathcote where skeleton-key interior sets still turn. These aren’t standard installations. They require a locksmith who understands mortise geometry, who carries period-correct cylinders, and who won’t suggest tearing out character-grade hardware because it’s easier. That’s our Lock Installation & Rekey team.
Why Strongbox Lock & Safe Co. of New York City Is Scarsdale’s Preferred Lock Installation & Rekey Company
Scarsdale homeowners call us back. They mention our technicians by name in reviews - the uniform, the ID badge at the door, the written quote that matches the invoice. Over 42 years, we’ve built a reputation in Westchester County for doing the job once and standing behind it. Our 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no argument.
We answer calls live, 24/7. Nights, weekends, holidays - a real person, every time. When you’re locked out of a Scarsdale home in February with a frozen mortise cylinder, you don’t want voicemail. You want someone who knows where you are and what’s wrong.
Our response time to Scarsdale averages under an hour for emergencies. We carry Medeco, Baldwin, and Yale cylinders on every truck, plus smart-lock retrofit kits sized for older door preps. That inventory matters here. Scarsdale’s housing stock is unlike neighboring municipalities - larger estates, architect-designed, built to last. The locks should be too.
Our Lock Installation & Rekey Services in Scarsdale
Smart Lock Installation
Scarsdale’s absentee homeowners - splitting time between here and the Hamptons, Florida, or overseas - drive steady demand for smart-lock retrofits. We install Yale and Schlage smart deadbolts that integrate with existing mortise bodies where possible, or we fabricate custom strike brackets when the door prep doesn’t match. A typical smart lock installation in Scarsdale runs $320-$580, including integration with your existing skeleton-key interior sets. We recently serviced a 1928 Tudor Revival on Brewster Road where the original Baldwin mortise lock had seized during a freeze-thaw cycle. We sourced a period-correct Baldwin brass mortise cylinder, rekeyed it to match the existing skeleton-key system, and upgraded the deadbolt to a Grade-1 Medeco for enhanced security - all while preserving the original decorative escutcheon.

Keyless Entry Systems
Keyless entry in Scarsdale means something different than in a new-build subdivision. Here, it’s often about granting access to housekeepers, contractors, and property managers without duplicating physical keys across a household that’s frequently empty. We install keypad and proximity systems that work alongside antique hardware, not against it. Entry sequences can be programmed, changed, or revoked remotely. Most Scarsdale keyless retrofits fall between $280-$520.

Keypad Lock Installation
Keypad locks suit side doors, pool houses, and carriage-house garages in Scarsdale’s larger estates. We favor commercial-grade units with weatherized keypads that withstand Westchester’s freeze-thaw punishment. Installation on solid-wood or steel-clad doors from the 1930s-1950s often requires custom strike-plate fabrication. Expect $240-$450 for most keypad installations in Scarsdale, with same-day service when the door prep is standard.

Biometric Lock Installation
Biometric locks - fingerprint readers - appeal to Scarsdale homeowners who want access control without codes to remember or keys to lose. We install fingerprint-enabled deadbolts from select manufacturers, with particular attention to cold-weather reliability. Westchester winters stress electronic components; we specify units rated for subzero operation and back them with our 90-Day Done Right Promise. Biometric installation in Scarsdale typically runs $380-$650.

Key Duplication
We duplicate keys on-site for Scarsdale customers - including the bit-and-barrel skeleton keys common to 1920s-1950s interior mortise locks, which most hardware stores cannot cut. We also duplicate modern Medeco and Mul-T-Lock high-security keys, which require specialized blanks and authorization. Key duplication runs $8-$35 per key depending on complexity, with master-key system coding available for multi-user estates.

Trusted Brands We Service in Scarsdale
We stock and install Medeco, Yale, and Baldwin hardware from our mobile inventory - the three brands we encounter most in Scarsdale’s older homes. Medeco for Grade-1 security upgrades on century-old doors. Yale for smart-lock retrofits that preserve existing trim. Baldwin for period-correct mortise cylinders and decorative escutcheons that match original 1920s-1950s installations. We don’t sell what we wouldn’t install on our own homes. And we don’t arrive with a truck full of one brand, hoping it fits. We carry the right stock for Scarsdale doors.
Common Lock Installation & Rekey Problems We See in Scarsdale Homes
- Freeze-thaw frame shift misaligns mortise deadbolts. Westchester County’s repeated freeze-thaw cycles from November through March cause settled door frames and aged threshold weatherstripping to shift, throwing mortise bolts and deadbolts out of strike alignment. The door won’t secure. We file strikes, reset hinges, and realign lock bodies - usually same-day.
- Corroded exterior keyways after winter ice exposure. Exterior keyways on these older homes ice over and corrode faster than modern cylindrical locks, generating a predictable winter service surge. We extract broken keys, replace pitted cylinders, and recommend weatherized covers where appropriate.
- Smart-lock retrofit brackets fail to match original door prep. Mixing modern smart-lock components with original mortise bodies often fails when the retrofit bracket doesn’t match the door prep, requiring custom fabrication. We measure, fabricate, and install - no gaping holes, no exposed screws.
- Absentee homeowners return to seized or corroded locks. A notable share of Scarsdale homeowners split time between this primary residence and secondary homes, leaving large estates empty for weeks. We install smart-lock systems with remote monitoring and master-key access for trusted staff - so you’re never locked out of your own home after a long absence.

FAQs - Lock Installation & Rekey in Scarsdale
We can usually rekey an original 1930s mortise cylinder to accept a modern key profile without replacing the entire lock body. We source period-correct mortise cylinders that fit the original case and match the decorative escutcheon - preserving your home’s character while updating key control. Call (877) 691-7931 to describe your lock; we’ll tell you if your cylinder is serviceable or needs replacement.
Yes - in most cases we install a smart deadbolt on the front door while leaving skeleton-key interior sets untouched. We select retrofit hardware that clears existing trim and fabricate custom strike brackets when the door prep doesn’t match standard templates. Your interior doors keep their original character; your entry gets modern access control.
Westchester’s freeze-thaw cycles shift door frames and compress weatherstripping, misaligning mortise bolts with strike plates so the door won’t latch or deadbolt. We realign strikes, reset hinges, and shim frames - usually same-day, without replacing the lock. If the bolt itself is damaged from repeated forcing, we replace just the bolt or cylinder, not the entire mortise body.
We can integrate master-key access with most antique mortise systems by installing a new master-keyed cylinder in the existing lock body. Each user gets a key that opens specific doors; you keep a grand master that opens all. We also layer in smart-lock codes for temporary access that you can revoke remotely. Estate master-key systems in Scarsdale typically run $450-$1,200 depending on door count and cylinder grade.
Usually not. We extract the broken or stuck key, inspect the cylinder for ice damage or corrosion, and replace just the cylinder if the mortise body is sound. Most frozen-key extractions in Scarsdale run $120-$220. If the mortise body itself is cracked - rare, but possible after decades of freeze stress - we’ll quote a full replacement with period-matched hardware. Call (877) 691-7931; we’ll walk you through what we see.
