We’re the Lock Installation & Rekey team that knows Compton’s housing stock inside out - the original 2-3/8″ backsets, the add-on wrought iron security doors, the decades of tenant turnover that leave cylinders worn past saving.

We’ve been serving Compton and surrounding communities for over 42 years. The city’s post-WWII bungalows built from the 1940s through the 1960s are familiar territory - narrow door preparations, mismatched hardware from decades of quick fixes, and that second locking system on nearly every house: the wrought iron security screen door. When you call us, you’re getting a technician who carries the right backset adapters, who knows which smart locks fit without boring new holes, and who won’t treat your security door as an afterthought.

Our Lock Installation & Rekey Services in Compton
Smart Lock Installation
Smart locks are increasingly popular with Compton landlords who manage multiple properties and need remote access control. But here’s the local reality: many Compton bungalows have that original 2-3/8″ backset, and not every smart lock accommodates it without drilling. We stock retrofit-ready Kwikset and Yale smart locks that fit narrow preparations, and we’ll tell you honestly if your door requires modification or if a different model makes more sense. We also check your wrought iron security door - some smart lock customers want keypad access on the outer door too, which means coordinating two electronic systems. We handle both. Typical smart lock installation in Compton runs $180-$320 including hardware.

Keyless Entry & Keypad Lock Installation
Keyless entry systems solve a real problem in Compton’s rental market: no more chasing down keys from departed tenants. We install mechanical and electronic keypad locks from Schlage and Baldwin that withstand heavy use. The marine-layer-to-inland-heat thermal cycling here is hard on electronics, so we specify weather-rated components for exterior doors and security screens. A standard keypad lock installation in Compton costs $140-$260. If you’re rekeying multiple units at a turnover, we often recommend keyless entry as the long-term cost saver - no more rekeying every six months.

Biometric Lock Installation
Biometric locks - fingerprint readers - are finding their way onto Compton’s duplexes and small apartment buildings where owners want to eliminate key distribution entirely. We install Medeco and Mul-T-Lock biometric units rated for commercial-duty cycles. These require precise door prep and clean power; we’ll survey your installation site and quote flat, including any needed striker plate adjustment on that second security door. Biometric installation in Compton typically runs $280-$450. Not every door is a candidate, and we’ll say so upfront.

Electronic Lock Service & Installation
Electronic locks with audit trails and scheduled access codes are standard equipment for Compton property managers handling Section 8 and other regulated housing. We service and install electronic locks from Sargent and Yale with features like auto-lock, tamper alerts, and master-override programming. Many of these integrate with existing intercom systems in converted duplexes and triplexes. Electronic lock work in Compton ranges from $160 for basic replacement to $380 for full networked installation. We also provide Key Duplication for properties staying with traditional cylinders - precision-cut on-site, working the first time.

Trusted Brands We Service in Compton
We install and service Kwikset, Medeco, Yale, and Baldwin - and we carry common cylinders, latches, and strike plates for Compton’s two-door setups on every truck. That means faster completion and fewer return trips. When we quote a job in Compton, we specify the brand and series, not “a comparable lock.” If your wrought iron security door needs a Schlage-grade commercial knob to survive tenant turnover, we’ll say so. If a Medeco high-security cylinder is overkill for your application, we’ll say that too. The right lock for the right door. That’s how we work.
Common Lock Installation & Rekey Problems We See in Compton Homes
- Thermal racking on wrought iron security doors. The daily swing from cool marine-layer mornings to warm inland afternoons gradually warps welded steel frames out of square. Striker plates misalign. Locks jam or won’t latch. We diagnose this on nearly every Compton security door call and correct it with plate adjustment or shimming - not just a new cylinder that will jam again in six months.
- Original 2-3/8″ backsets blocking standard deadbolt replacement. Compton’s postwar bungalows were built with narrow door preparations. Forcing a modern 2-3/4″ backset deadbolt bores a hole that weakens the old door. We stock adapters and specify compatible hardware so your door stays intact.
- Cylinders worn beyond rekeying from decades of tenant cycling. Rekeying requires intact pin chambers. When keys have been forced, pins are damaged, or chambers are wallowed out, rekeying produces a lock that fails again quickly. We inspect before we commit and recommend full cylinder replacement when that’s the honest answer.
- Multi-unit properties needing master-key or keyed-alike systems. Garage conversions and unpermitted ADUs are common on Compton’s small lots. A “house call” becomes a three-unit rekey with different access levels. We carry the pinning kits and code books to build master-key hierarchies on-site.

FAQs - Lock Installation & Rekey in Compton
Yes, it’s extremely common here. The daily thermal swing from marine-layer cool to inland heat gradually racks welded steel frames out of square, misaligning striker plates. We correct this with plate adjustment and shimming, not just a new cylinder. Call (833) 294-4584 - we’ll diagnose both your security door and main entry lock together.
Yes, and we typically key them alike so one key operates both. We serviced a duplex on Compton Boulevard in the 90220 ZIP where the landlord needed a full rekey after a tenant move-out. The front door had a worn Kwikset deadbolt with a 2-3/8″ backset, and the wrought iron security door’s Schlage knob was seized due to thermal frame drift. We replaced both cylinders with matching keyed-alike Schlage units and adjusted the striker plate on the security door. Call (833) 294-4584 for a flat quote on your property.
Yes, with the right hardware selection. We stock Kwikset and Yale smart locks that fit 2-3/8″ preparations without boring new holes. We’ll verify your door’s condition and specify a compatible model before quoting. Call (833) 294-4584 - we’ll confirm fit and price over the phone.
Yes. Garage conversions and backyard ADUs are common on Compton’s small postwar lots, and we regularly build keyed-alike or master-key systems for multi-unit properties on the spot. We’ll survey access needs - owner override, tenant privacy, maintenance access - and pin cylinders accordingly. Call (833) 294-4584 to schedule.
Sometimes, but often no. Decades of tenant cycling in Compton’s rental stock leaves pin chambers worn or damaged. Rekeying a compromised cylinder produces a temporary fix that fails quickly. We inspect first and recommend honestly - rekey if the chamber’s sound, replace if it’s not. Either way, the price we quote is the price you pay. Call (833) 294-4584 for a free look.
