Why Strongbox Lock & Safe Co. of Philadelphia Is Fullerton’s Preferred Lock Installation & Rekey Company
Fullerton homeowners call us because we understand what we’re walking into. The post-WWII housing stock here - mostly twins and small ranches built from the 1950s through the 1970s - presents a specific set of lock problems that newer suburban developments simply don’t have. Original builder-grade knob locks with no deadbolt. Steel storm door combinations that fight every upgrade. Keyways worn smooth after sixty years of use. We’ve solved these problems in Fullerton hundreds of times.
Our reputation here is built on showing up when we say we will, quoting a real price on the phone, and standing behind the work. The 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no argument. Dale Corrigan has led Strongbox with this standard since the beginning, and it’s why Fullerton customers stay with us for decades.
Every technician who comes to your door is background-checked, uniformed, and carries ID. You’ll know who you’re letting into your home. And the price we quote is the price on the invoice - period. We’ve seen too many Fullerton residents burned by the $19-ad locksmith scam that triples the bill once the truck arrives. That doesn’t happen here.
Our Lock Installation & Rekey Services in Fullerton
Deadbolt Installation
Most Fullerton homes were built with knob-only entry locks and no deadbolt. That was standard construction in the 1960s, but it doesn’t meet modern security needs. We install Schlage and Kwikset deadbolts specifically chosen for Fullerton’s door frames, which are thinner and more settled than newer construction. The steel storm doors common here often require strike plate adjustment or closer re-positioning to clear the new deadbolt throw. We handle that on-site, not as an add-on.

Rekeying
Moving into a Fullerton twin or ranch? Rekeying changes the internal pin configuration so old keys no longer work - same lock, new key. For original Kwikset B-profile knobs still common in Fullerton, rekeying is often possible and costs less than full replacement. But after sixty years of wear, some keyways are too degraded to accept new pins cleanly. We’ll tell you honestly which path makes sense, with the flat price quoted before any work begins.

Smart Lock Installation
Fullerton’s retirees and long-term homeowners are increasingly asking about keyless entry. We install keypad and electronic locks from Schlage and Yale that integrate with existing deadbolt prep - critical in these older homes where door modification is limited. For ranches with steel storm doors, we verify clearance for the smart lock’s housing and battery pack before recommending a model. Not every smart lock fits every Fullerton door, and we’ll say so upfront.

Biometric and Keypad Lock Options
For homeowners who want to eliminate keys entirely, biometric and keypad locks offer direct entry without fumbling for a key in the dark or cold. In Fullerton, where the Lehigh Valley winter can leave fingers stiff and keys dropped in snow, this matters. We install these with attention to the freeze-thaw cycling that affects door frame alignment - a lock that works in September may bind by January if installed without accounting for seasonal wood movement.

Trusted Brands We Service in Fullerton
We stock and install Schlage, Kwikset, and Medeco hardware with local parts availability for Fullerton customers. That means faster turnaround and no waiting for a special order from a warehouse three states away. Schlage’s commercial-grade deadbolts hold up well in Fullerton’s high-use twin home entries. Kwikset’s SmartKey technology allows future rekeying without disassembling the lock - useful for rental units or family homes where key control changes. Medeco’s high-security cylinders resist picking and bumping, which matters for homeowners who want more than standard protection. We carry the full line, not just what fits in a van.
Common Lock Installation & Rekey Problems We See in Fullerton Homes
- Steel storm door screens block deadbolt installation. The steel-frame screen/storm door combinations extremely common in Fullerton’s ranches often position the screen door frame directly in the path of a new deadbolt throw. We adjust the closer arm, relocate the strike, or select a shorter-throw deadbolt to clear the interference without leaving the door undersecured.
- Original knob-only locks have worn keyways that won’t rekey. Fullerton’s 1960s Kwikset B-profile knobs have been in service for sixty-plus years. The keyway walls wear, the pin chambers oval out, and new pins won’t seat with the precision rekeying requires. When we encounter this, we quote replacement honestly - no charge for the diagnosis, and the flat price includes everything.
- Freeze-thaw frame shifts cause newly installed locks to bind. The Lehigh Valley’s pronounced freeze-thaw cycling - temperatures regularly oscillating through 32°F from November into March - causes wooden door frames in Fullerton’s mid-century housing stock to swell, shift, and bind lock bolts. A lock that operated smoothly in autumn may stick by February. We account for this in installation, using adjustable strikes and proper backset depth to maintain function through seasonal movement.
- Shared twin-home wall means both units’ locks misalign simultaneously. In Fullerton’s twin homes, the shared interior wall means both units’ front doors sit on the same structural frame. When one neighbor’s door frame shifts from freeze-thaw movement, the adjoining unit’s lock alignment is often affected simultaneously. We frequently end up servicing both halves of a twin on a single dispatch, rekeying both to match or installing paired deadbolts that function through the same seasonal stress.
We recently serviced a twin home on Maple Street where the original 1960s Kwikset B-profile knobs were binding in both units due to frame swelling. We installed Schlage deadbolts in both doors and rekeyed them to match, solving the alignment issue and upgrading security from the builder-grade originals.

FAQs - Lock Installation & Rekey in Fullerton
Yes, very possibly. In Fullerton’s twin homes, the shared interior wall means both front doors sit on the same structural frame, and freeze-thaw movement in that frame commonly misaligns both units’ locks simultaneously. We often diagnose this by checking both doors even when only one was called in. Call (844) 643-4161 and we’ll assess whether rekeying, strike adjustment, or deadbolt installation is the right fix - estimates are free.
Sometimes they can be rekeyed, but often the keyway is too worn after sixty years for new pins to seat precisely. We’ll test yours on-site and tell you honestly which path costs less and secures better. If replacement is needed, we quote the full flat price before any work begins. Call (844) 643-4161 to schedule a look.
It depends on the specific storm door geometry and the smart lock model. Many smart locks require more clearance than a steel storm door provides, or their battery housing interferes with the screen frame. We measure before recommending, and we stock models known to work in Fullerton’s common storm door configurations. Call (844) 643-4161 and we’ll verify fit before you buy anything.
The Lehigh Valley’s freeze-thaw cycling - temperatures regularly crossing 32°F from November through March - causes Fullerton’s wooden door frames to swell and shift seasonally. A lock installed without accounting for this movement will bind when the frame expands. We use adjustable strikes, proper backset depth, and hardware selected for seasonal tolerance to prevent this. If your current installer didn’t, we can correct it. Call (844) 643-4161.
Yes, and we do this regularly in Fullerton. Rekeying both units on one dispatch saves you money and ensures the locks are keyed alike or separately as you prefer, with both functioning through the same seasonal frame movement. The typical range for a twin-home dual rekey is $80-$140. Call (844) 643-4161 for a flat quote - estimates are free.
