We’ve worked in Monrovia for decades. We know the difference between a standard rekey on a Kwikset deadbolt in a 1960s ranch near Huntington Drive and a delicate mortise-lock service on a 1920s bungalow off Myrtle Avenue. That local knowledge saves time and protects your doors.

Our Lock Installation & Rekey Services in Monrovia
Smart Lock Installation
Smart lock installation in Monrovia costs $180-$420, including the lock, installation, and pairing with your phone or home system. Many Monrovia homeowners in the foothills want remote access for rental units or family members, but they also need hardware that withstands Santa Ana wind grit and temperature swings. We install Schlage Encode and Yale Assure models rated for exterior exposure, and we make sure the strike plate is properly seated in older door frames that may have settled or warped. For homes near Monrovia Canyon Park, we can pair smart locks with reinforced deadbolts for layered security.
Keyless Entry & Keypad Lock Installation
Keypad locks suit Monrovia’s multi-generational households and vacation rentals. Installation runs $150-$320. We see strong demand in the hillside neighborhoods above Foothill Boulevard, where homeowners want to grant access to gardeners or housekeepers without hiding a key under a planter. Keypad locks eliminate that risk. We program user codes on-site and show you how to add or delete them. For historic bungalows in Old Town, we select low-profile models that don’t dominate a period door.
Biometric Lock Installation
Biometric locks, using fingerprint recognition, start at $280 installed in Monrovia. These make sense for home offices, workshops, and detached garages in the canyon-adjacent areas where you may want quick, keyless access without fumbling in the dark. We install units from trusted manufacturers and verify they function reliably in Monrovia’s temperature range. Fingerprint sensors can struggle with very dry skin, common in our Santa Ana wind conditions, so we demonstrate proper enrollment technique and backup access methods.
Key Duplication
Key duplication in Monrovia is $4-$18 per key, depending on the blank. We cut standard Kwikset and Schlage keys while you wait, and we stock blanks for older skeleton-key systems found in Monrovia’s Craftsman bungalows. If you have a mortise lock with a bit key, bring it in. We can duplicate those too, a service most hardware stores in the San Gabriel Valley no longer offer. For high-security Medeco or Mul-T-Lock keys, we verify authorization before cutting, as these restricted blanks require proper credentials.
Rekeying Services
Rekeying changes the internal pin configuration so old keys no longer work. In Monrovia, rekeying a standard deadbolt costs $45-$85 per cylinder. For historic mortise locks, the range is $75-$140 due to the specialized pinning and the care required with aged brass components. Rekeying is the practical choice after a move, a lost key, or a staffing change. It’s faster than full replacement and preserves hardware that matches your home’s character.

Common Lock Installation & Rekey Problems We See in Monrovia Homes
- Santa Ana wind grit seizes exterior cylinders. Monrovia’s position at the base of the San Gabriel Mountains channels dry, dusty wind directly into lock mechanisms. We regularly find foothill homeowners unable to turn their deadbolts after a wind event. Cleaning and lubricating with graphite, not oil, solves it. For repeat problems, we recommend weather-sealed cylinders.
- Temperature swings bind deadbolts in wooden frames. The foothills see 30-degree day-to-night swings that cause door frames to expand and contract. In winter, the deadbolt throw may not align with the strike plate. In summer, the opposite. We diagnose whether the lock needs adjustment or the frame needs shimming.
- Original mortise locks are damaged by inexperienced technicians. The historic bungalows around Myrtle Avenue and Old Town carry locks that require skeleton keys and specific disassembly sequences. Forcing the mechanism or drilling it out destroys hardware that is difficult to replace. Our technicians have worked on these systems for decades.
- Standard gate hardware fails against wildlife. In upper Monrovia near Monrovia Canyon Park, bears have opened simple gate latches. We install cane bolts, heavy-throw deadbolts, and latch guards that resist prying. This is a Monrovia-specific concern that locksmiths in flatland cities never encounter.

FAQs - Lock Installation & Rekey in Monrovia
They drive fine grit into lock cylinders, causing sticking and eventual seizing, especially in foothill homes near Monrovia Canyon Park. The dry, pressurized wind carries mineral dust from the San Gabriel Mountains directly into exterior hardware. We recommend weather-sealed cylinders and annual maintenance with dry graphite lubricant, not oil-based products that attract more grit. Call (833) 294-4584 to schedule a seasonal tune-up for $89.
Yes. We regularly rekey mortise locks in the Craftsman and Spanish Colonial Revival homes around Old Town and Myrtle Avenue. These locks use different pinning systems than modern cylinders and require specialized tools and knowledge of skeleton-key bitting. We preserve the original hardware while updating the keying for your security. Not every locksmith in the San Gabriel Valley works on these systems. We do.
Heavy-throw deadbolts, cane bolts on wooden gates, and latch guards that resist prying force. Standard residential hardware is not designed for wildlife intrusion. We recently serviced a 1920s Craftsman bungalow on Myrtle Avenue where a bear had pried open a wooden gate with a standard latch. We reinforced the gate with a cane bolt and installed a heavy-throw Schlage deadbolt to resist similar intrusions, while preserving the home’s original mortise lock on the front door with a period-appropriate rekey. For upper Monrovia properties, we assess every access point, not just the front door.
Yes. The pronounced day-to-night temperature swings in Monrovia’s foothills cause wooden door frames to expand and contract enough to bind deadbolt throw bolts seasonally. You may find the deadbolt stiff in winter and loose in summer, or the strike plate may no longer align. We adjust, shim, or relocate strike plates as needed. Sometimes the solution is a properly installed adjustable strike rather than replacing the lock itself.
Yes, and we select models that work with older door construction. Many Monrovia bungalows have thinner doors, non-standard backsets, or mortise pockets that complicate modern deadbolt installation. We measure on-site and recommend Schlage or Yale models that fit without damaging period woodwork. For homes where a full smart lock isn’t practical, we can install smart keypads on secondary doors or garages. Call (833) 294-4584 for an assessment.
