We’ve worked Philadelphia’s narrow streets and tighter-than-tight parking for over 42 years.

Why Strongbox Lock & Safe Co. of Philadelphia Is Philadelphia’s Preferred Lock Installation & Rekey Company
Philadelphia’s unmatched density of 19th- and early 20th-century brick rowhouses means the city is saturated with original mortise locksets - the deep, rectangular mechanisms set into the door stile - rather than the cylindrical deadbolts standard in newer construction. A Philadelphia locksmith who cannot rekey, rebuild, and source parts for antique Corbin, Sargent, and Yale mortise locks will lose a dominant share of residential calls, a demand virtually nonexistent in newer Sunbelt or suburban markets. We keep those parts on our trucks. We recently responded to a call in Fishtown where a homeowner thought their front door lock was broken. What we found was a 1920s Corbin mortise case with a worn cam follower and dried lubricant - the cylinder turned but wouldn’t throw the bolt. Instead of selling a new deadbolt, we cleaned and rebuilt the internal mechanism, saving the owner the cost and preserving the original hardware, which is exactly what keeps word-of-mouth strong in these neighborhoods.
Our Lock Installation & Rekey team has built a strong local reputation across Philadelphia’s rowhouse neighborhoods. Customers in Point Breeze, Kensington, and West Philly call us back because we diagnose before we sell. A live person answers every call, 24/7 - no voicemail trees, no callback queues, no exceptions. Our background-checked, uniformed technicians present ID at every door, and the price we quote on the phone is the price on the invoice. Every job carries our 90-Day Done Right Promise, backed in writing with no extra paperwork.
Our Lock Installation & Rekey Services in Philadelphia
Smart Lock Installation
Smart lock installation in Philadelphia rowhouses presents real challenges that suburban installers rarely face. Your 1920s door may be 1¾ inches thick with a mortise pocket eating up most of the stile, leaving little real estate for a modern smart deadbolt. We measure first, then recommend units that fit without chewing through vintage wood. Typical smart lock installation in Philadelphia runs $280-$450 including hardware setup and smartphone pairing. We install Schlage Encode, Yale Assure, and Kwikset Halo models that integrate with existing Wi-Fi - no hub required.

Electronic Lock & Keypad Entry
Electronic locks and keypad entry systems work well on Philadelphia’s pre-hung steel security doors, which are common over original wood entries in South Philly and Pennsport. We mount the keypad on the steel outer door and wire it to release both the electronic strike and the inner mortise bolt. Electronic lock installation in Philadelphia typically costs $220-$390. For commercial properties on Chestnut Street or in Center City office conversions, we install Sargent and Yale networked systems with audit trails and scheduled access codes.

Key Duplication
Key duplication in Philadelphia isn’t always straightforward. Mortise lock keys, especially older Yale and Corbin bit-key patterns, don’t feed through standard hardware store machines. We cut these on manual duplicators and can often fabricate working keys from broken fragments. Standard house key duplication runs $4-$8 per key. Antique mortise keys or high-security Medeco blanks run $18-$35. We stock Philadelphia’s most common keyways, including the Kwikset KW1 and Schlage SC1 profiles found in post-1955 rowhouse renovations.

Biometric Lock Installation
Biometric locks - fingerprint readers - suit Philadelphia homeowners who want keyless entry without remembering codes. We install these primarily on secondary doors: basement entries, garage-access doors in West Philly twins, and rear kitchen doors in Point Breeze rowhouses where carrying groceries makes fumbling for keys a nuisance. Fingerprint lock installation in Philadelphia runs $320-$480. We favor units with mechanical key override, because biometric sensors can struggle in Philadelphia’s humid summer months when fingers are damp.

Trusted Brands We Service in Philadelphia
We install and service the full range of premium security hardware: Schlage, Medeco, Mul-T-Lock, Abloy, Baldwin, Yale, Kwikset, and Sargent. For Philadelphia’s older housing stock, our trucks carry Sargent mortise lock parts and Yale cylinder components that national chains don’t stock. When your 1930s Baldwin entry set needs a new spindle or your Medeco high-security cylinder needs pinning, we don’t order and make you wait - we fix it now. That parts availability is why our turnaround on Philadelphia lock repairs averages same-day, while competitors quote a week for “special order” components we keep on hand.
Common Lock Installation & Rekey Problems We See in Philadelphia Homes
- Worn cam followers in antique mortise locks cause the cylinder to spin freely without retracting the bolt. Homeowners think the lock is broken and need replacement. Usually, a rebuild of the internal mechanism - cleaning, lubricating, replacing the cam follower - solves it for a fraction of the cost. We see this constantly in South Philly and Fishtown.
- Seasonal wood swelling in rowhouse door frames binds mortise bolts, especially after January freezes or the first major summer heat wave. The lock isn’t failing; the frame has shifted. We adjust the strike plate and sometimes plane the jamb rather than sell you hardware you don’t need.
- Frozen exterior cylinders in damp mid-Atlantic cold trigger unnecessary drilling by impatient locksmiths. Philadelphia’s winter humidity means ice forms inside the cylinder plug. A proper diagnosis - de-icer, gentle warming, or lubricant with a low freezing point - opens the door without destroying your lock.
- Layered security doors complicating smart lock retrofits. Many Philadelphia homes have a pre-hung steel security door over the original wood entry with its mortise lock. Installing keyless entry means coordinating both doors so one code or fob releases both bolts in sequence. We engineer this properly rather than leaving you with two separate locks and two separate keys.

FAQs - Lock Installation & Rekey in Philadelphia
Yes, in most cases we can rekey or rebuild your mortise lock while preserving the original case and hardware. We remove the cylinder, repin it to a new key, and inspect the internal mechanism for worn cams or dried lubricant. If the case itself is sound, replacement is unnecessary. Call (844) 643-4161 - we’ll assess it over the phone and give you a flat price for rekeying or rebuilding.
Philadelphia’s humid summer heat causes wooden door frames in older rowhouses to swell, binding the bolt against the strike plate. The lock isn’t failing; the frame has expanded. We adjust the strike, sometimes plane the jamb slightly, and ensure the bolt throws smoothly year-round. If your deadbolt sticks every July, call us - it’s a 30-minute fix, not a lock replacement.
Yes, but it requires careful measurement and often custom mounting. Old Philadelphia doors are thick, with mortise pockets that reduce available stile width. We select smart locks with compact backsets and reinforce the mounting area when needed. Not every smart lock fits every old door, but we carry models that do. Call for a free assessment - we’ll tell you honestly if your door is a candidate or if a keypad on your steel security door makes more sense.
In Philadelphia’s damp, mid-Atlantic cold, yes - exterior cylinder freeze-ups are common from December through February. Moisture enters the keyway, freezes overnight, and blocks the plug from turning. A locksmith who drills the lock without diagnosing this destroys perfectly good hardware. We use lock de-icer and lubricants formulated for low temperatures. If your lock freezes repeatedly, we can install a weather-rated cylinder or adjust the door sweep to reduce moisture intrusion.
Yes. This is a standard Philadelphia configuration, especially in South Philly and Kensington. We mount the keypad or smart lock on the steel outer door and coordinate it with the inner mortise lock so one action releases both bolts. You can choose keyed-alike mechanical backup or independent systems. Installation typically runs $260-$420 depending on the hardware. Call (844) 643-4161 for a free estimate - we’ll walk you through the options that fit your setup.
