Allentown’s dense neighborhoods, from the South Side rental blocks to the Sixth Ward’s alley-load doors, present lock challenges you won’t find in suburban markets. Tight clearances, original mortise hardware, and doors that have shifted through decades of Lehigh Valley winters require a technician who has worked this exact stock before. We have. Our trucks carry the spacers, vintage cylinders, and narrow-profile smart lock kits that Allentown’s housing actually needs.
Why Strongbox Lock & Safe Co. Is Allentown’s Preferred Lock Installation & Rekey Company

Our technicians are background-checked, uniformed, and present ID at the door on every visit. In a city where you’re handing someone access to your home, that verification matters. We’ve served the Lehigh Valley for over 42 years, and we plan to be here in thirty more. That long view shapes how we treat every job.
Response time to Allentown averages 25-40 minutes during business hours, with 24/7 emergency lockout and re-key service available nights, weekends, and holidays. Calls are answered by a live person - no voicemail trees, no callback queues, no exceptions.
We understand Allentown’s housing intimately: the mortise locksets in 18103 South Side rowhouses, the swelling interior doors of pre-war stock in the Sixth Ward, the alley-load entries where standard smart locks simply won’t fit without modification. This is not generic locksmith work.
Our Lock Installation & Rekey Services in Allentown
Smart Lock Installation
Smart lock installation in Allentown runs $180-$340 for most residential doors, but the real question is whether your door can accept one. Many Sixth Ward and South Side rowhouses have narrow stiles or shallow backsets that prevent standard smart lock installation without a spacer kit or minor door modification. We carry slim-profile Schlage and Kwikset smart lock models specifically for these tight clearances, and we’ll tell you honestly if your existing door needs work before we quote the full job. Our 90-Day Done Right Promise covers the installation and the hardware - if it doesn’t function as promised, we come back. No paperwork, no arguing.

Keyless Entry
Keyless entry systems are increasingly popular among Allentown landlords managing multiple rental units, especially in the 18103 corridor where tenant turnover is constant. A keypad or electronic entry system eliminates re-keying between tenants and provides audit trails for property management. We install and program Medeco and Schlage keyless systems that integrate with existing door prep where possible, preserving the original door’s integrity in historic properties. For landlords with clusters of adjacent rowhouses, we can key alike or master-key across multiple units - one visit, coordinated access. The price quoted on the phone is the price you pay, and every system is backed by our written 90-Day Done Right Promise.

Keypad Lock
Keypad lock installation in Allentown typically costs $160-$290 installed, depending on whether your door needs strike adjustment or prep work. These are workhorse solutions for rental properties and multi-generational homes where keys get lost or shared unpredictably. We’ve installed hundreds in Allentown’s rowhouse stock, including units on Hamilton Street and the South Side blocks where original wooden doors have swollen and shifted. A keypad eliminates that problem entirely. We stock weather-resistant models rated for the freeze-thaw cycles that seize lesser hardware, and we program them on-site before we leave.

Biometric Lock
Biometric lock installation in Allentown starts around $220-$380 for residential-grade fingerprint readers, with commercial systems running higher. These units demand precise alignment and clean power, so we assess your door’s condition and clearance before quoting. In Allentown’s older housing, we often need to address underlying issues - a racked frame, a swollen door, a corroded strike - before the biometric mechanism will function reliably. We do that prep work as part of the installation, not as an add-on surprise. Our technicians carry the narrow-profile biometric models that fit where standard units won’t.

Key Duplication
Key duplication in Allentown runs $4-$12 per standard key, with high-security blanks like Medeco or Abloy running $18-$35. We cut keys on-site from code or from your existing key, including skeleton keys for original mortise locks that many shops can’t duplicate. Landlords in the South Side often need ten, fifteen, twenty keys cut after a batch re-key - we handle that volume while you wait, with verification that every key operates every lock before we leave. It’s part of the same visit, same flat price, same written guarantee.

Electronic Lock
Electronic lock installation covers a broad category - from simple push-button units to networked access control - and in Allentown’s rental market, we see demand across that full spectrum. Typical residential electronic lock installation runs $170-$320. For landlords managing multiple properties, we can install standalone electronic locks or advise on integrated systems. The Lehigh Valley’s humidity and temperature swings mean we specify hardware with proven environmental ratings, not budget units that fail after two seasons. We install what we’d put on our own doors.

Trusted Brands We Service in Allentown
We stock and install Schlage, Kwikset, and Medeco hardware from our local inventory, which means faster turnaround for Allentown customers and no waiting for special orders on common items. Schlage’s residential and light commercial lines handle the bulk of our deadbolt and smart lock installations. Kwikset’s SmartKey system offers landlords a re-keyable cylinder they can reset themselves between tenants - a practical choice for high-turnover properties. Medeco’s high-security cylinders and key control systems protect against unauthorized duplication, critical for property managers and homeowners who need key accountability. We also service and install Abloy, Mul-T-Lock, Baldwin, Yale, and Sargent where the application calls for it. The right lock goes on the right door, not just what’s on the truck.
Common Lock Installation & Rekey Problems We See in Allentown Homes
- Freeze-thaw cycles seize original mortise cylinders. Allentown’s position in the Lehigh Valley floor creates sharp cold-air pooling in winter. Original mortise locksets in pre-1940 rowhouses, common throughout 18103 and the Sixth Ward, seize when moisture enters the cylinder and freezes. Standard re-keying fails if the cylinder is corroded inside - we diagnose this before quoting, and we stock replacement mortise cylinders that fit vintage hardware without destroying the door’s original character.
- Summer humidity swells original wooden doors and misaligns strikes. The interior doors in Allentown’s pre-war stock are solid wood, not hollow-core modern units. They swell in July and August humidity, causing latches to miss strikes that aligned perfectly in October. Even new deadbolts won’t latch until the strike plate is repositioned. We address this as part of installation, not as a separate “discovery.”
- Tight clearances on alley-load and townhome doors block standard smart lock installation. Many Sixth Ward and South Side entries have narrow stiles, shallow backsets, or decorative molding that prevents standard smart lock mounting. We carry slim-profile models and spacer kits specifically for these conditions, and we’ll modify the door prep where necessary - always with your approval and a clear price before we start.
- Batch re-key demand from high-turnover rental clusters. Allentown’s South Side has some of the highest tenant-turnover rates in the Lehigh Valley. Landlords who own adjacent rowhouses on the same street routinely schedule a single technician to re-key four or five units in one visit. This batch workflow is routine for our Allentown operation but rare in suburban markets like Macungie or Lower Macungie. We coordinate master-keying, key-alike grouping, and key duplication in one efficient visit - the price is quoted flat before we arrive.

FAQs - Lock Installation & Rekey in Allentown
Yes, in most cases we can re-key or replace the cylinder while preserving the original mortise lock body. Last winter we serviced a six-unit brick row on South 8th Street in the Sixth Ward where the original 1910 mortise locksets had seized from freeze-thaw. We re-keyed all units to a master-keyed Schlage system, preserving the vintage hardware while giving the landlord single-key access. If the cylinder is too corroded inside, we stock replacement mortise cylinders that fit without modifying the door. Call (877) 664-8139 - we’ll diagnose it on the phone and quote a flat price before we roll.
Yes, we can master-key or key-alike across multiple adjacent properties in a single visit. Allentown’s South Side rental blocks see this request regularly - landlords with clusters on Hamilton Street, South 8th, or nearby corridors schedule batch re-keys to minimize vacancy downtime. We coordinate the pinning, cut all keys on-site, and verify every key operates every lock before we leave. The flat price covers the full visit; call (877) 664-8139 to schedule.
Often yes, but it depends on your door’s exact stile width and backset depth. Many Sixth Ward alley-load doors have clearances too tight for standard smart lock mounting. We carry slim-profile Schlage and Kwikset models and spacer kits specifically for these conditions. We’ll measure and advise before quoting - if your door needs minor prep work, that’s included in the flat price we give on the phone. Call (877) 664-8139 to arrange a free assessment.
A standard residential re-key in Allentown runs $89-$140 per cylinder, with no separate service call fee. Mortise lock re-keying or cylinder replacement runs $120-$195.
