Why Strongbox Lock & Safe Co. Is North Hills’s Preferred Lock Installation & Rekey Company
We’ve built our reputation in North Hills one door at a time. Homeowners here remember the bait-and-switch operators who quoted $19 over the phone and handed them a $400 invoice. We do the opposite: flat price quoted upfront, backed by our 90-Day Done Right Promise in writing. No paperwork to file. No argument. If it’s not right, we come back.
Our technicians are background-checked, uniformed, and present company ID at every door in North Hills - whether it’s a single-family stucco home off Nordhoff or a 1970s apartment building near Sepulveda and Roscoe. The person who opens your locks should be the most verifiable person you’ve ever hired.
Calls are answered by a live person, 24/7, including nights, weekends, and holidays. No voicemail trees. No callback queues. Gil Navarro set this standard decades ago, and we haven’t relaxed it.
We also understand what other locksmiths miss: North Hills’s concentrated stock of post-WWII tract homes absorbed severe ground motion during the 1994 Northridge earthquake, and the resulting foundation shifts created chronic door-frame misalignment that standard lock installations simply don’t address. A technician from Encino or Sherman Oaks doesn’t encounter this at the same rate. We do. We shim, relocate strike plates, and reinforce jambs as part of the job - not as an upsell.
Our Lock Installation & Rekey Services in North Hills
Smart Lock Installation
Smart lock installation in North Hills typically costs $280-$450 including the device, with Yale and Schlage being our most reliable performers on older doors. The question we hear most: will a smart lock work on a 1960s door with a quake-racked frame? Usually yes, but it requires more than a standard install. We often need to plane the door edge, install a reinforced strike box, or add a wrap plate to compensate for the 1/8″-3/16″ misalignment common in North Hills foundations. We recently replaced a 1970s-era Kwikset single-cylinder deadbolt on a Roscoe Boulevard tract home where the frame had racked 3/16″ from the quake; we reinforced the strike with a 2-3/8″ heavy-duty plate and rekeyed the matching knobs to a single key for the homeowner. The smart lock we installed - a Yale Assure - has operated without binding for two years since.
Keyless Entry
Keyless entry systems in North Hills range from $220-$380 installed, depending on whether we’re retrofitting a standard deadbolt location or drilling fresh holes in a hollow-core apartment door. The Sepulveda Boulevard corridor’s 1970s apartment buildings are a particular specialty. Many still run original master-key systems that have been patched by multiple technicians over three decades. We can install standalone keyless entry on individual units without disturbing the building’s master system - a practical solution for landlords who aren’t ready to rekey the entire property. For homeowners in the tract home neighborhoods, we favor Baldwin and Schlage keyless deadbolts with mechanical backup cylinders, since Wi-Fi connectivity can be spotty in some pockets of North Hills.
Keypad Lock
Keypad lock installation in North Hills runs $180-$320. These are popular with families near the North Hills East pocket who want the kids to get in without managing keys. The heat factor matters here: North Hills regularly hits 100-108°F in summer, and cheap keypad housings warp or fade within two seasons. We install only UV-stabilized units with rubberized gaskets, and we always check whether your aluminum-frame security door expands enough to bind the bolt throw in August. If it does, we’ll spot the problem and address it - not leave you with a keypad that works nine months of the year.
Biometric Lock
Biometric lock installation in North Hills starts at $340 and can reach $520 for multi-factor units with keypad backup. These make sense for home offices, gun rooms, or properties with high tenant turnover where keys keep getting lost. The fingerprint sensors we install - primarily Kwikset Halo Touch and Yale biometric models - are rated for the temperature swings of the San Fernando Valley. We always verify door frame squareness before quoting biometric installs, since the motorized deadbolt mechanisms have less tolerance for misalignment than manual throws. On quake-shifted North Hills frames, that verification step is non-negotiable.
Key Duplication
Key duplication in North Hills costs $4-$12 per key for standard Kwikset and Schlage blanks, with Medeco and Mul-T-Lock high-security keys running $18-$35. We stock blanks for the brands we install - no sending you to a hardware store with a half-working key. For landlords near Sepulveda and Roscoe, we maintain key records by property address and can reproduce duplicates from our files if a tenant loses their only set. That’s faster and cheaper than rekeying the cylinder every time a key walks off with a departing renter.

Trusted Brands We Service in North Hills
We install and service Kwikset, Medeco, Yale, and Baldwin hardware - brands we’ve stocked parts for since before North Hills was incorporated as its own community. Kwikset remains the most common legacy brand in local 1950s-1970s homes, and we carry the full range of replacement cylinders, latches, and strike plates to match. For homeowners upgrading security without replacing the entire door prep, Medeco and Yale offer high-security cylinders that drop into existing Kwikset deadbolt housings. We keep these in stock at our Los Angeles shop, so most North Hills jobs don’t wait on parts. If your Baldwin hardware needs service, we have the specialized tools and pinning kits - not every locksmith does.
Common Lock Installation & Rekey Problems We See in North Hills Homes
- Thin-gauge original strike plates bend or break under misaligned deadbolts from earthquake-shifted frames. We replace these with 2-3/8″ heavy-duty strike plates with 3″ screws that bite into the framing, not just the jamb.
- Aging Kwikset deadbolts (pre-2000) fail to retract fully in summer heat when aluminum frames expand and bind the bolt. Rekeying won’t fix this - the bolt mechanism itself is worn. We diagnose this on arrival and quote the repair honestly.
- Compromised master-key systems in Sepulveda Boulevard corridor apartments lock out tenants after multiple patch jobs cause keyway wear. These systems need systematic rebuilding, not another band-aid. We assess whether to rekey the cylinder, replace it, or redesign the master hierarchy entirely.
- Hollow-core doors on rental units can’t support standard deadbolt backsets without reinforcement. We install wrap plates and door edge guards as standard practice on these doors, not as add-ons.

FAQs - Lock Installation & Rekey in North Hills
Yes, in most cases, though it requires additional prep work that standard installs don’t. We typically need to shim or plane the door edge, install a reinforced strike box, and sometimes add a wrap plate to compensate for the 1/8″-3/16″ misalignment common in North Hills foundations. The smart lock itself - Yale and Schlage units handle this best - mounts normally once the door prep is corrected. Call (877) 664-8139 and we’ll assess your frame over a quick photo or site visit; estimates are free.
We can rekey a single apartment cylinder without disturbing the building’s master key hierarchy, though we need to verify the system’s pinning chart first. The Sepulveda corridor’s 1970s-era buildings often have compromised master systems patched by multiple technicians over 30 years, so we may recommend a systematic rebuild if keyway wear is severe. Single-unit rekeys run $120-$165; full system assessment is $95 and credited toward any rebuild work. Call for a free evaluation.
We do, but only with reinforcement - wrap plates and door edge guards that distribute the bolt pressure across the door face. Hollow-core doors alone can’t withstand forced entry and will split around a standard deadbolt. Our installs on these doors include the reinforcement as standard, not as an upsell. Typical cost: $220-$295 with Kwikset or Schlage hardware installed. We won’t put a deadbolt on a hollow door without it.
No. Rekeying changes which key operates the lock; it doesn’t fix mechanical binding from thermal expansion. North Hills’s 100-108°F summer heat expands aluminum frames enough to misalign deadbolt throws and cause latch misses. The fix is frame adjustment, strike plate relocation, or in severe cases, replacing the aluminum frame with a thermally stable steel unit. We diagnose binding causes on arrival and quote the actual repair, not a rekey you don’t need. Call (877) 664-8139 for an exact assessment.
Yes, provided the cylinders and bolt mechanisms are still functional. Original Kwikset hardware from the 1970s is generally rebuildable, though we often find thin-gauge strike plates and worn latches that should be replaced at the same time. Rekeying to a single key runs $120-$165 for two cylinders (front door and garage, for example), with new keys included. If the quake shifted your frame, we’ll include strike plate relocation and shimming in the quote. Call for a free estimate - we’ll inspect the hardware condition on site.
