Our Lock Installation & Rekey Services in Claremont
Smart Lock Installation
Smart locks make sense for Claremont’s rental market, especially near the Claremont Colleges where landlords manage multiple properties and remote access simplifies turnover. We install Wi-Fi and Bluetooth-enabled deadbolts from Schlage and Yale that integrate with existing door prep - critical on 1920s craftsman doors with non-standard bore holes. Our technicians carry adapters and escutcheon plates specifically for these older Claremont homes, so you don’t end up with gaps or misaligned hardware. A typical smart lock installation in Claremont runs $280-$450 including hardware and labor.
Keyless Entry Systems
Keyless entry eliminates the rekeying cycle entirely - a practical solution for Claremont landlords who face August and May turnover rushes on streets like 10th, 11th, and 12th. We install standalone keypad deadbolts and hardwired access-control systems for multi-unit buildings, all programmed on-site. For faculty housing and small apartment complexes near the colleges, we can set up tiered access codes that expire automatically. Keyless entry installation in Claremont typically costs $220-$520 depending on network integration and door condition.
Keypad Lock Installation
Keypad locks bridge old and new - mechanical push-button models work without batteries or Wi-Fi, making them reliable for Claremont’s hillside homes where power outages during Santa Ana wind events aren’t rare. We stock mechanical and electronic keypads from Kwikset and Schlage, and we know which models tolerate the dust and heat cycles that define inland Southern California. Installation runs $180-$340 for most Claremont residential doors.
Biometric Lock Installation
Biometric locks - fingerprint readers - suit Claremont homeowners who want maximum control and no keys to lose or copy. We install residential-grade biometric deadbolts that store multiple fingerprints, with override keys for backup. On older Claremont doors, we reinforce strike plates and jambs to handle the deeper hardware these units require. Biometric installation typically runs $320-$580.
Electronic Lock Service & Installation
Electronic locks cover everything from simple push-button models to networked systems with audit trails. In Claremont, we see strong demand from the institutional market - the Claremont Colleges consortium, with its seven campuses, runs complex master-key and electronic access systems that dwarf typical residential needs. Our technicians understand both worlds: the single-family home on Mountain Avenue and the multi-building master key system at the colleges. Electronic lock service in Claremont starts at $150 for diagnostics and reconfiguration, with full installations from $260-$620.
Key Duplication & Master Key Systems
We cut keys on-site for all major brands and build master key hierarchies for Claremont landlords and small commercial clients. Student rental turnover drives steady demand each semester - we can rekey an entire property to a new master in one visit, with all keys cut and working before we leave. Master key rekeying in Claremont runs $85-$150 per cylinder, with volume discounts for multi-unit properties.

Trusted Brands We Service in Claremont
We stock and install Schlage, Kwikset, Medeco, and Yale hardware from our local inventory, which means most Claremont jobs need no special-order delay. Schlage’s residential smart locks handle our heat and dust cycles well. Medeco’s high-security cylinders suit landlords who need key control - no unauthorized duplicates possible. Yale’s electronic line integrates cleanly with home automation systems popular in newer Claremont builds. We carry mortise cylinders and adapters for the vintage locksets still common in north Claremont’s historic homes, so we’re not forcing modern hardware where it doesn’t belong.
Common Lock Installation & Rekey Problems We See in Claremont Homes
- Santa Ana dust infiltration. Claremont sits at the base of the San Gabriel Mountains, and those intense Santa Ana winds drive fine particulate dust deep into pin-tumbler and wafer mechanisms. Keys stick, bind, or refuse to turn - a failure pattern we see far less often in coastal LA cities where the marine layer keeps airborne dust damp and heavy.
- Heat-expanded door frames. Summer temperatures routinely hit 100°F+ in Claremont, causing metal door frames and thresholds to expand. Deadbolts feel frozen or resistant even when the lock itself is sound. The fix is usually strike-plate adjustment, not lock replacement - but only if the technician recognizes what’s actually happening.
- Aging mortise hardware in historic homes. The craftsman bungalows and Tudor revival homes north and central Claremont, built between the 1910s and 1940s, often still run original mortise locksets. These require different tooling, different parts, and different expertise than standard cylindrical locks. We’ve seen inexperienced locksmiths damage irreplaceable vintage hardware by forcing modern components where they don’t fit.
- Corrosion from occasional marine layer push. Despite being inland, Claremont occasionally catches moisture from marine layer pushes that slip through the Puente Hills gap. Garage-door springs and hinges on older tract homes show accelerated corrosion - a secondary issue we check when we’re already on-site for lock work.

FAQs - Lock Installation & Rekey in Claremont
Most Claremont landlords near the colleges rekey between every tenant, typically twice yearly aligned with the August and May move cycles. The Claremont Colleges’ academic calendar is predictable - new leases start August 1 and May 15 - so you can schedule rekeying in advance rather than scrambling. We offer volume pricing for multi-unit properties and can master-key your buildings so you carry one key, tenants carry another, and maintenance staff has a third. Call (877) 664-8139 to set up a seasonal schedule - estimates are free.
Yes, and more than most residents realize until their key starts sticking. Claremont’s position at the base of the San Gabriel Mountains funnels Santa Ana winds directly through the city, carrying fine mountain and desert dust into pin-tumbler chambers where it abrades metal surfaces and causes binding. We see this failure mode constantly in Claremont and rarely in coastal cities where humidity keeps dust from becoming airborne. Annual lubrication with dry graphite - not oil, which attracts more dust - helps, but severely contaminated cylinders need professional cleaning or replacement.
Mortise-style locksets or high-quality cylindrical deadbolts with decorative escutcheons that cover existing bore holes without damaging original woodwork. North Claremont’s 1910s-1940s homes often have 2-3/8″ backsets and non-standard door prep that modern hardware won’t fit without modification. We stock Sargent and Baldwin mortise cylinders that match vintage aesthetics while providing modern security, plus adapters that let us install Schlage or Kwikset deadbolts without drilling new holes in irreplaceable old-growth doors. The right lock preserves your home’s character. The wrong lock destroys it.
Yes, with the right preparation and hardware selection. Old wooden doors in Claremont’s historic districts are often thicker, harder, and more brittle than modern softwood doors, requiring slower drilling and specialized bits to prevent splitting. We carry reinforced strike plates and longer screws to anchor into solid framing behind century-old trim. Smart locks from Schlage and Yale offer retrofit models specifically designed for non-standard door prep. A typical smart lock retrofit on a Claremont craftsman door runs $320-$480 including necessary modifications.
Metal expansion from extreme heat, not lock failure. Claremont’s 100°F+ summer days cause steel door frames and brass thresholds to expand by fractions of an inch - enough to misalign strike plates and make deadbolts drag or feel frozen. The lock itself is fine; the geometry has shifted. We adjust strike-plate position and check frame squareness, which usually solves it permanently. If a previous installer simply forced the lock to work despite misalignment, you may also have internal wear that needs addressing. Call (877) 664-8139 - we’ll diagnose whether it’s expansion, wear, or both, and quote the fix before we start.
