We’ve been driving to Selden since the early 1980s, back when the Pine Barrens still felt like a real buffer between here and the city. Our technicians know the difference between a Hawkins Ave split-level and a ranch off Bicycle Path, and we know which deadbolts were thrown in during the 1972 construction boom and which have been replaced three times by landlords cutting corners. That matters because a lock that looks fine from the outside can have a cylinder so worn that rekeying it is throwing good money after bad. We’re the Lock Installation & Rekey team that tells you the truth about your hardware, even when the truth is “this needs to go.”
Why Strongbox Lock & Safe Co. Is Selden’s Preferred Lock Installation & Rekey Company
We’ve served Suffolk County for over 42 years, and Selden has been a core part of our route since the hamlet was still filling in with cape cods and ranches for the LIRR commuter crowd. Our reputation here is built on showing up when we say we will - usually within 45 minutes for emergency calls - and on technicians who present ID at the door in uniform, every single time.
Selden customers specifically mention our flat-price quoting in reviews. They’ve been burned by the $19-ad locksmiths who roll up in an unmarked car and invent a “drilling fee” on the spot. We don’t operate that way. The price we quote on the phone is the price on the invoice. Period.
Our local knowledge runs deep. We know which Selden neighborhoods have the original 1960s Kwikset knobsets that share discontinued keyways. We know which rental complexes near Middle Country Road have seen so many tenant turnovers that the lock cylinders are essentially smooth inside. And we know that freeze-thaw cycle that hits every January, when the phone starts ringing about deadbolts that worked fine in November and now won’t throw.
Our Lock Installation & Rekey Services in Selden
Smart Lock Installation
Selden’s older homes present a specific challenge for smart locks. The door frames on those ranch and split-level builds weren’t designed for the torque and thickness of modern electronic deadbolts. We reinforce the strike jamb, check the door edge for proper bore alignment, and make sure your Yale or Schlage Connect actually seats cleanly without binding. In that split-level home on Hawkins Ave, we replaced a worn-out Kwikset deadbolt from the 1970s - no longer keyable alike with the tenant’s new Schlage - with a Baldwin smart lock, integrating it with the homeowner’s smart home system for quiet, keyless entry. The wood frame needed shimming. We did it right, not fast.

Keyless Entry
Keyless entry systems are increasingly popular with Selden’s aging homeowners who are done with fumbling for keys in the dark. We install keypad and touchscreen entry on front doors, side entries, and even garage man-doors. For the ranch homes common in the 11784 ZIP, we pay special attention to the back door - often an original hollow-core with a minimal prep that can’t handle a heavy electronic lock without reinforcement. We quote that reinforcement upfront. No surprises.

Keypad Lock
Keypad locks bridge the gap between traditional hardware and full smart-home integration. They’re reliable, they don’t depend on Wi-Fi, and they’re straightforward to reprogram when a tenant turns over or a housekeeper changes. In Selden’s rental market, that’s a practical advantage. We install Kwikset SmartCode and Schlage keypad deadbolts with codes that won’t fade in the humidity of a Suffolk County summer, and we show you how to change them yourself.

Biometric Lock
Biometric locks - fingerprint readers - are no longer exotic. We install them on Selden homes where keys have become a genuine burden, whether due to arthritis, memory concerns, or simply a preference for clean, keyless living. The technology has improved; modern biometric sensors handle the temperature swings of Central Suffolk County better than early generations. We still recommend a mechanical backup, and we’ll explain why during your free estimate.

Trusted Brands We Service in Selden
We stock and install Medeco, Yale, and Baldwin hardware for Selden customers, with same-day availability on most common configurations. Medeco for the homeowner who wants pick-resistance and key control. Yale for clean smart-home integration with reliable app support. Baldwin for the custom finish that matches existing brass or oil-rubbed bronze hardware on a cared-for home. We don’t show up with whatever’s on the truck and hope it works. We match the lock to the door, the door to the frame, and the whole assembly to how you actually live.
Common Lock Installation & Rekey Problems We See in Selden Homes
- Freeze-thaw deadbolt misalignment. Central Suffolk County’s freeze-thaw cycles cause the wood door frames common in Selden’s ranch-style homes to swell in winter and shrink in summer, chronically throwing deadbolt-to-strike alignment out of spec. We see this every January. The fix isn’t always the lock - sometimes it’s the frame, and we’ll tell you which.
- Worn cylinders from repeated rekeying. Selden’s rental density drives steady rekeying demand, but many older builder-grade locksets have been rekeyed so many times the cylinders are worn to the point where new keys no longer fit securely. At that stage, replacement is the only reliable fix. We’ll show you the wear and explain why.
- Custom carriage-house door binding. Custom carriage-house doors with thick wood can bind against electronic deadbolts if not properly reinforced, leading to motor burnout or jammed bolts. We measure the door thickness, check the backset, and install reinforcement plates before the smart lock goes in.
- Discontinued keyways on original hardware. Those 1970s Kwikset and Weiser locks often used keyways that are no longer manufactured. Rekeying becomes impossible. Keying alike with new hardware becomes impossible. The only path forward is replacement, and we’ll help you choose hardware that matches your security needs and your budget.

FAQs - Lock Installation & Rekey in Selden
Sometimes, but often not reliably. Original builder-grade locks from the 1960s-70s Long Island boom frequently have worn tumblers, discontinued keyways, or cylinders that have been rekeyed so many times they no longer hold pin settings securely. We inspect first. If rekeying is viable, we’ll do it. If the cylinder is too worn, we’ll explain why replacement is the better spend and quote both options on the phone. Call (877) 664-8139 for a free estimate - we’ll ask the right questions about your hardware before we drive.
Yes, and it’s one of the most common service calls we get every winter. The wood frames on Selden’s ranch and split-level homes swell in cold, humid weather and shrink in dry summer heat, gradually shifting the strike plate out of alignment with the deadbolt. The lock isn’t broken. The frame has moved. We adjust or relocate the strike, check the door hinges for sag, and get the bolt throwing cleanly again. Call (877) 664-8139 - same-day service is usually available.
Yes, with proper prep. Custom carriage-house doors with thick wood require reinforcement behind the lock body and careful bore alignment to prevent binding that burns out the motor or jams the bolt. We measure door thickness, check backset, and use finish-protective techniques during installation. We also match hardware finish to existing fixtures - Baldwin and Yale both offer options that complement traditional carriage-house styling. Call (877) 664-8139 to schedule a look.
Replace the locksets. Repeated rekeying grinds down cylinder pins and widens chambers until new keys sit loose, catch, or fail to turn. This is especially common in Selden’s higher-turnover rentals with original 1970s hardware. Rekeying a worn cylinder is temporary at best. We install new hardware with fresh, precise tolerances - Medeco or Schlage for durability, or Kwikset SmartKey if you anticipate frequent future rekeying. Call (877) 664-8139 for landlord pricing and volume scheduling.
Yes, and we do it properly. Older split-level door frames in Selden often have minimal prep - thin jamb stock, shallow bore depth, or hinge sag that throws the whole door out of square. We reinforce the strike side, check and adjust hinges if needed, and install the electronic lock so it doesn’t bind or overtorque. The result is a keyless entry that works smoothly in August humidity and January cold. Call (877) 664-8139 for a free estimate and flat quote.
