Call (877) 664-8139 for a flat price before we roll - no bait, no switch.
Why Strongbox Lock & Safe Co. Is Altadena’s Preferred Lock Installation & Rekey Company
Altadena homeowners aren’t looking for the cheapest bid. They’ve seen the $19-ad scam, and they remember the technician who quoted one price on the phone and another at the door. We don’t work that way. The price we quote is the price you pay. Period.
Our 90-Day Done Right Promise backs every job in writing - no paperwork to file, no argument to have. If it’s not right, we come back. That’s been our standard for over four decades, and it’s why Altadena residents from the lower avenues near Mariposa Street to the canyon-edge homes off Chaney Trail call us back for second and third jobs.
Because Altadena is unincorporated LA County, the Sheriff’s response times to canyon-edge streets near Chaney Trail can exceed 30 minutes, making residents willing to pay a premium for rapid-response rekeying after a break-in - a dynamic absent in incorporated Pasadena. We understand this reality. Our background-checked, uniformed technicians show ID at every door, and a live person answers every call, 24/7, including nights, weekends, and holidays. When security can’t wait on a patrol car, we get there fast.
We rekeyed a 1920s Spanish Colonial Revival cottage on Loma Alta Drive after the homeowner lost all keys during the Eaton Fire evacuation. The original mortise lock required a rare Corbin cylinder blank - we sourced it from our vintage stock, matched the skeleton key cut, and installed a new Schlage deadbolt as a primary lock for security compliance. That’s the kind of problem-solving Altadena’s housing stock demands.
Our Lock Installation & Rekey Services in Altadena
Smart Lock Installation in Altadena
Smart locks on Altadena’s vintage doors aren’t plug-and-play. The wood thickness on 1920s Craftsman entry doors often exceeds standard specs, and the beveled edges that give these doors their character prevent flush mounting of standard smart lock hardware. We custom-shim and router where needed, integrating Yale and Schlage smart deadbolts that actually seat properly and communicate reliably with your home network. We’ve installed keyless entry systems in restored bungalows near Mendocino Street and new builds in the rebuilt Eaton Fire zones alike - each job measured to the door, not to a generic template.

Keyless Entry Systems
Keyless entry means different things depending on which Altadena neighborhood you’re in. For the mid-century ranch homes near New York Drive, a clean keypad lock with a satin nickel finish matches the aesthetic without drilling new holes. For the Spanish Revival cottages around Santa Rosa Avenue, we often recommend Baldwin hardware with concealed mounting to preserve the original door face. Our technicians carry multiple finish options on every truck serving the 91001 and 91003 ZIP codes, so you’re not stuck with whatever was in the warehouse.

Keypad Lock Installation
Keypad locks solve a specific problem in Altadena’s rental and temporary housing market, which exploded after the January 2025 Eaton Fire displaced thousands of residents. Property managers and homeowners hosting displaced families need rapid rekeying without chasing down physical keys. We install and program Medeco and Schlage keypad locks that allow code changes in under 60 seconds - no locksmith visit required for tenant turnover. For the rebuilt homes going up on Altadena’s burned lots, keypad locks offer a practical bridge between construction-phase access and permanent residential security.

Biometric Lock Installation
Biometric locks - fingerprint readers, primarily - are increasingly requested for Altadena’s hillside estates above Loma Alta Drive, where wrought-iron gates and secondary structures need access control without the bulk of traditional hardware. We install Mul-T-Lock and Yale biometric units rated for outdoor exposure, calibrated for the temperature swings that come with foothill living. These aren’t the finicky consumer-grade units that fail after one wet season. We spec commercial-grade readers with weather sealing appropriate to Altadena’s Santa Ana wind cycles and summer heat spikes.

Trusted Brands We Service in Altadena
We stock and install Kwikset, Medeco, Yale, and Baldwin hardware from our Los Angeles-based inventory, with same-day parts availability for most Altadena service calls. That matters when you’re dealing with obsolete Corbin cylinders in a Spanish Revival mortise box or need a specific Baldwin rosette to match existing door hardware. We don’t show up with one brand and talk you into it. We bring what’s right for your door, your security needs, and your home’s character. Our technicians carry the full range on their trucks - no return trips, no “we’ll order that and come back next week.”
Common Lock Installation & Rekey Problems We See in Altadena Homes
- Seasonal deadbolt binding on sun-baked wood doors. Altadena’s position at the base of the San Gabriel Mountains produces wide daily temperature swings that cause door frames to expand and contract enough to make deadbolts bind or misalign seasonally. We see this every August on homes above Loma Alta Drive, where late-summer sun bakes wood-framed doors that were installed with standard backsets and no seasonal adjustment gap. The fix is precise mortising with expansion tolerance, not forcing the bolt.
- Mortise lock replacement gaps. Replacing original mortise locks with modern Kwikset hardware without matching the existing escutcheon hole pattern leaves unsightly gaps and weakens door integrity. We see this botch job frequently on Altadena’s 1920s-1950s housing stock, where a previous owner or handyman routed out vintage hardware and slapped in a standard bore. Our repair includes custom escutcheon plates or proper mortise-to-bore conversion that preserves door strength.
- Smart lock mounting failures on Craftsman doors. Smart lock installations on Craftsman-style wooden doors often fail because the wood thickness or bevel prevents flush mounting, requiring custom shimming that generic instructions ignore. We’ve removed dozens of poorly seated smart locks from Altadena bungalows, reinstalled correctly with proper spacing and strike alignment.
- Post-fire rekeying urgency. The January 2025 Eaton Fire burned through large sections of Altadena specifically - not neighboring Pasadena or San Marino - making post-fire locksmith work the single most defining service demand in this community. We secure vacant and damaged lots against looting, install hardware on newly rebuilt homes, and re-key temporary housing for displaced residents on timelines that generalist locksmiths can’t meet.

FAQs - Lock Installation & Rekey in Altadena
We typically rekey temporary housing in Altadena within 2-4 hours of your call, and same-day service is standard for fire-displaced residents in the 91001 and 91003 ZIP codes. We maintain expanded stock for the post-fire surge and prioritize calls from FEMA-assisted housing and rebuilt lots. Call (877) 664-8139 - we’ll give you a flat quote and a real arrival window, not a four-hour “sometime today” runaround.
Yes, but it requires custom fitting that standard installation instructions don’t cover. Altadena’s Craftsman doors are typically thicker and more steeply beveled than modern prehung units, so we router additional clearance and custom-shim the mounting plate for flush contact. We’ve installed Yale and Schlage smart locks on dozens of Altadena bungalows from Mendocino Street to the upper avenues - done right, they look original and function reliably.
Yes, we stock vintage Corbin cylinder blanks and mortise components specifically for Altadena’s Spanish Colonial Revival housing stock. These parts are obsolete at most suppliers, but we’ve maintained inventory for over 42 years of local service. If your original mortise box is salvageable, we can rekey it to match a new skeleton key or integrate a modern Schlage deadbolt for primary security - the approach we used on the Loma Alta Drive cottage post-Eaton Fire.
Altadena’s late-summer heat swells sun-baked wood door frames, compressing the deadbolt strike tolerance that was set during cooler months. The daily temperature swing from cool foothill mornings to 90-plus afternoons accelerates the cycle. We fix this by resetting the strike with seasonal expansion gaps, not by forcing the bolt deeper. It’s a ten-minute adjustment that prevents the lock from jamming entirely when you need to evacuate during Santa Ana wind events.
Yes, we install keyless entry on Altadena’s wrought-iron estate gates, including the older Corbin-style and non-standard gate hardware common on hillside parcels above Loma Alta Drive. These installations require weather-hardened keypad or biometric units with proper strike alignment for gate swing, plus battery or low-voltage power solutions. We spec Medeco and Mul-T-Lock outdoor-rated hardware, not indoor locks slapped on a gate. Call (877) 664-8139 for a free on-site assessment and flat quote.
