Our Lock Installation & Rekey Services in Del Aire
Smart Lock Installation
Del Aire’s LAX shift-worker population drives real demand for smart locks. Nurses, baggage handlers, air traffic controllers, they don’t keep 9-to-5 schedules. A smart lock lets them grant temporary access to dog walkers or family members without hiding a key under a planter. We install Schlage Encode, Yale Assure, and Kwikset Halo models that integrate with existing deadbolt prep holes, even on the heavier FAA-retrofitted doors where alignment is already touchy. Our Lock Installation & Rekey team measures door thickness, backset, and jamb condition before recommending hardware. Retrofit doors often measure 1-3/4 inches instead of the original 1-3/8, and not every smart lock accommodates that without modification.

Keypad Lock Installation
Keypad locks are the workhorse choice for Del Aire’s rental properties and multi-generational households. No phone required, no Wi-Fi dependency, just a six-digit code that can be changed in thirty seconds when a tenant moves out or a caregiver’s access needs to end. We install Schlage and Kwikset keypad deadbolts with motorized bolts that tolerate the slight frame racking common in sound-insulated homes. If your door has shifted since the FAA retrofit, we’ll shim the strike or deepen the mortise so the bolt throws clean every time. Typical keypad installation in Del Aire runs $180-$290 including hardware.

Biometric Lock Installation
Fingerprint locks have come down in price and up in reliability. For Del Aire homeowners who want keyless entry without remembering codes, we install biometric deadbolts from recognized manufacturers with capacitive sensors that work through minor grime and temperature variation. These require precise door prep, which is why our field measurement matters. A biometric lock misaligned by even 1/8 inch won’t seat properly, and on a retrofitted door with a racked jamb, that tolerance is everything. We don’t sell you a lock that won’t fit. We measure first, quote flat, then install.

Key Duplication
Key duplication sounds simple until you’re holding a worn Medeco or Mul-T-Lock key that the hardware store machine can’t read. We cut high-security keys on code machines with factory-spec blanks, not the guesswork you get from a self-service kiosk. For Del Aire’s older homes, we also duplicate the original Kwikset and Schlage keys that may have been rekeyed two or three times since 1955. Key duplication runs $4-$18 per key depending on blank type, and we stock Del Aire’s most common profiles so you’re not waiting on a parts order.

Trusted Brands We Service in Del Aire
We install and service Schlage, Kwikset, Medeco, Mul-T-Lock, Abloy, Baldwin, Yale, and Sargent. For Del Aire’s sound-insulated homes, we keep adjustable strikes, extended lip plates, and thicker door hardware in stock because we’ve learned what these retrofitted doors need. A standard strike plate from the big-box store often won’t cover the gap left by a shifted jamb. We carry the parts that do. That means one trip, one flat price, and a lock that works the day we leave and six months later.
Common Lock Installation & Rekey Problems We See in Del Aire Homes
- Deadbolt throw misalignment from FAA-retrofit door weight. The heavy insulated slabs installed under the Residential Sound Insulation Program displaced original wood jambs over time. The deadbolt that threw smoothly in 2010 now grinds or won’t extend. We shim, adjust, or replace the strike plate, and if the jamb has racked severely, we reinstall with longer screws into the framing.
- Strike plate screws loosened by low-frequency aircraft vibration. Constant vibration from LAX arrivals at low altitude works fasteners loose in 60-year-old wood frames. It’s not imagination. We’ve found strike plates hanging by a single screw in homes directly under the approach path. We replace with 3-inch screws into the stud and use thread-locking compound.
- Incompatible lock prep on replacement door slabs. The FAA program’s replacement doors often came with standard 2-1/8 inch bore holes, but the original 1950s doors in Del Aire used different backsets or smaller face bores. A deadbolt installed without adapting the prep will bind, wobble, or fail to seat. We measure and adapt on site.
- Rekeying needs after lost keys from shift-worker turnover. Del Aire’s high concentration of airport employees means roommates, house-sitters, and temporary arrangements are common. Rekeying is cheaper than replacing hardware and restores key control immediately. A typical Del Aire rekey runs $120-$180 for 2-3 locks.

What moves you within these ranges? Hardware grade is the big one. A Schlage B60N Grade 1 deadbolt costs more than a Kwikset SmartKey entry lock, but it’ll also take more abuse and last longer on a door that’s already working against its frame. Labor complexity matters too. A straightforward swap on a plumb door takes forty minutes. A retrofit door with a racked jamb, stripped screws, and non-standard prep can run two hours. We quote flat before we start. The price on the phone is the price on the invoice. Seniors and veterans receive a permanent 5% discount. Repairs over $250 qualify for $50 off.

FAQs - Lock Installation & Rekey in Del Aire
The heavy insulated door slabs installed under the FAA program displaced your original wood jamb over time, causing the deadbolt hole and strike plate to fall out of alignment. This is a failure pattern we see almost exclusively in Del Aire and other LAX flight-path communities. We fix it by shimming or relocating the strike, deepening the mortise, or in severe cases, reinstalling the jamb with proper shimming against the framing. Call (833) 294-4584 for a free assessment.
Yes. The low-frequency vibration from aircraft passing at low altitude gradually loosens strike plate screws, deadbolt alignment, and hinge fasteners in older wood frames. It’s a slow-creep failure that locksmiths in Del Aire encounter far more often than peers in inland South Bay cities. We prevent recurrence by using longer screws into the stud and thread-locking compound on critical fasteners. If your strike plate has worked loose repeatedly, this is likely why.
Usually, yes, but the door thickness and jamb condition must be verified first. Retrofit doors often measure 1-3/4 inches rather than the original 1-3/8, and the added weight may have racked the frame. We measure on site, confirm the smart lock’s adjustable backset range, and address any alignment issues during installation. Not every smart lock suits every retrofitted door. We won’t sell you one that doesn’t fit.
For the original 1950s stock, Schlage Grade 1 deadbolts offer the best balance of durability and retrofit compatibility. For homes with significant jamb racking from the FAA program, we often recommend Medeco or Mul-T-Lock with adjustable strikes and reinforced boxes that tolerate minor misalignment. The right lock depends on your door’s specific condition, which is why we inspect before quoting. Call (833) 294-4584 to schedule.
If the key won’t turn because the cylinder has shifted with the jamb, forcing it can damage the pins. We remove the cylinder, rekey it to a new key code, and correct the underlying alignment issue so the new key operates smoothly. A rekey after retrofit typically runs $65-$95 per cylinder including the new keys. If the cylinder itself is damaged from forced turning, replacement may be more economical. We’ll tell you straight which path saves money.
